A foreign founder can face a surprisingly specific obstacle when recruiting in France: the new employee has never worked in France and has no French social security number. An online form may ask for a NIR, the French national social security identification number, or a NIA, the temporary registration number used while identification is pending. That screen often leads an overseas director to conclude that the employee cannot be declared. The official rule is more useful: the absence of a NIR or NIA does not, by itself, prevent the prior declaration of employment from being taken into account.

The declaration is called the DPAE, short for déclaration préalable à l’embauche, or prior declaration of employment. It is a legal filing made by the employer before the employee starts work. It is not a work permit, not an employment contract, and not a substitute for registration of the employer’s French establishment. It is one part of a chain that also includes employee registration with the primary health insurance fund, occupational health, the personnel register, payroll and the monthly social declaration.

This article addresses a French company, branch or other employer engaging a person to work in France. It focuses on the practical answer to the crisis question: what should a foreign founder enter when the employee has no French number, and what should be done when the DPAE is nevertheless rejected? The answer is to use truthful identity data, request the appropriate registration route, preserve proof, and diagnose the actual error instead of manufacturing a number. For the wider incorporation sequence, the firm’s French company formation and compliance page provides the corporate context.

I. Can you file a French DPAE without a French social security number?

A. Can a foreign employee be declared without a NIR or NIA?

Yes, in the ordinary private-sector case covered by the general social-protection regime, the employer can file the DPAE even when the employee does not yet have a French social security number. This is not an informal workaround. The current URSSAF DPAE guidance expressly states: “Si votre salarié n’a ni numéro de Sécurité sociale ni NIA (numéro d’immatriculation d’attente), la déclaration est tout de même prise en compte.” In English, the declaration is still taken into account when the employee has neither a social security number nor a temporary registration number.

That sentence corrects a common but damaging assumption. The employer should not enter a random sequence, copy another employee’s number, put the company’s SIRET in the employee field, or use a number inferred from a passport. A false identifier can attach the declaration to the wrong person, corrupt a future payroll record, and create a much harder identity correction. The absence of a number is a fact to report; it is not a field to disguise.

The legislative text points in the same direction. Article R. 1221-1 of the French Labour Code requires the employee’s name, first names, sex, date and place of birth, and refers to “son numéro national d’identification s’il est déjà immatriculé à la sécurité sociale.” The qualifying words “s’il est déjà immatriculé” mean “if the employee is already registered with social security.” The number is supplied when it already exists; the provision does not turn a foreign employee’s first contact with the French system into a reason to invent one.

The DPAE still has to be filed. Article L. 1221-10 states that “L’embauche d’un salarié ne peut intervenir qu’après déclaration nominative accomplie par l’employeur.” In English, a salaried employee may only be hired after the employer has made the nominative declaration. The legal focus is therefore the employer’s timely and accurate declaration, not whether the employee already possesses a French identifier.

The first DPAE can also initiate several registrations. Under Article R. 1221-2 of the Labour Code, the employer uses the filing for, among other matters, “L’immatriculation du salarié à la caisse primaire d’assurance maladie.” The CPAM, or caisse primaire d’assurance maladie, is the primary health insurance fund. It is therefore coherent for the first declaration to precede the employee’s final French number: the declaration supplies the data that allows the competent body to process the employee’s registration.

A foreign founder should distinguish three questions that are often collapsed into one portal error:

• Has the employer identified the correct French entity and establishment?
• Has the employer sent a DPAE before the employee starts work?
• Does the employee already have a French social security number?

The first question concerns the company. The second concerns the employer’s legal deadline. The third concerns the employee’s social-protection identification. A “no” answer to the third question does not automatically produce a “no” answer to the first two. It may cause the CPAM to request supporting documents later, but that administrative follow-up is different from a failure to make the DPAE.

The same distinction matters for a foreign founder who sees a red error banner labelled “NIR missing.” First, check whether the message is a warning, a rejected transmission, or a payroll-software validation failure. URSSAF’s public guidance says the declaration is taken into account without a NIR or NIA, but a private payroll interface may be applying a stricter rule intended for a later payroll file. The employer should save the exact error, ask the provider which field is mandatory, and, if necessary, transmit through the competent official channel. A software screen is evidence of a technical event; it is not the source of the legal obligation.

There are limits to this answer. The worker’s lack of a French number does not remove the need to check the right to work, the applicable social-security regime, the actual place of work, or the identity of the legal employer. A posted worker, a person who normally works outside France, an agricultural worker, a seafarer and a person hired by a foreign company without a French establishment may fall under additional or different procedures. The correct response to those facts is a legal classification, not a false NIR.

For a French subsidiary of a foreign parent, the subsidiary is generally the employer if it signs the contract, directs the work and pays the salary. For a French branch, the branch’s establishment details and the registered foreign company’s identity must be kept consistent. For a foreign company with no French establishment, the founder must not assume that the subsidiary route applies. The question is always: which entity has the employer’s legal powers, where is the employee working, and which social-protection body receives the declaration?

B. Which identity details are needed when the employee has no French number?

The absence of a NIR does not mean that the identity section can be incomplete. It means that the employer must prepare the other mandatory details with unusual care. Article R. 1221-1 is the starting point. In addition to the employer information, it lists the employee’s name, first names, sex, date and place of birth, the number only if already registered, the date and time of hiring, and the nature and duration of the contract with the relevant probation information. The exact form fields can vary with the filing channel, but the underlying data must remain coherent.

For a foreign-born employee, collect the name exactly as it appears on the identity document, while preserving the distinction between family name and given names. Confirm accents, hyphens, compound names, transliteration and the order in which names appear. Record the date of birth, the town or locality of birth, the country of birth and the requested birth-department information where the system requires it. A person born outside France should not be forced into a French department code merely to pass a validation rule.

Keep a copy of the identity document in the employer’s secure personnel file, subject to the rules applicable to personal data. The document is not a substitute for the DPAE. It is supporting evidence for accurate data entry and for a later CPAM request. The founder should record who checked it, when it was checked and whether the name in the contract matches the name in the declaration. An English-speaking parent company should receive a clear internal summary, but the French source fields should remain available to the French employer and its advisers.

If the employee has a NIA, enter it only if it is the number actually issued to that employee. A NIA is the numéro d’immatriculation d’attente, a temporary registration number. It is not a placeholder chosen by the employer. If there is no NIA, leave the number absent through the route that permits absence and use the employee’s other identification data. If a system does not permit that route, ask URSSAF or the payroll provider to confirm the compliant channel rather than inserting a made-up value.

Prepare the employer data in a separate checklist. The SIREN is the nine-digit identifier for the legal business. The SIRET is the fourteen-digit identifier for a particular establishment. The APE code, meaning activité principale exercée, is the principal activity code. The company’s legal name, registered address, establishment address, SIRET, APE code and occupational-health service should be copied from the current corporate and employer records, not from an old draft of the articles.

A Kbis is the official extract showing a commercial company’s registration in the Trade and Companies Register. The RCS, or Registre du commerce et des sociétés, is that Trade and Companies Register. Since company formalities are now filed through the INPI one-stop process in many cases, the founder may also hold an RNE record. The RNE is the Registre national des entreprises, or National Business Register, and INPI is the Institut national de la propriété industrielle, the French National Institute of Industrial Property. A Kbis or RNE record proves corporate information; it does not prove that a particular employee’s DPAE was transmitted on time.

Before opening the form, create one data sheet with two columns: “source document” and “DPAE field.” Include the following items:

• the legal employer’s exact name and legal form;
• the employer’s SIREN and the SIRET of the establishment where the employee will work;
• the APE code and the establishment’s real work address;
• the competent URSSAF, meaning the Union for the Recovery of Social Security Contributions and Family Allowances;
• the occupational-health service or the service-registration reference;
• the employee’s name, first names, sex, date and place of birth and country of birth;
• the NIR or NIA, only if one has genuinely been assigned;
• the date and exact time of the planned start;
• the type and duration of the contract and the probation period when relevant; and
• the work-authorisation documents where the employee is a national of a country whose immigration status requires authorisation.

Do not confuse the company’s registered office with the employee’s workplace. A domiciliation address may be appropriate for corporate correspondence but may not be the place where the employee performs duties. The establishment attached to the DPAE should reflect the place connected with the employment. If the employee will work in two establishments, travel between locations or work remotely from another country, obtain a specific classification before filing. A NIR question cannot be answered correctly while the employer and workplace remain unidentified.

Work authorisation is separate. A foreign employee may need an immigration or work-authorisation check even though the DPAE can be filed without a NIR. The DPAE does not legalise an unauthorised employment relationship, and a work permit does not replace the DPAE. The employer should store the evidence of the authorisation check separately from the social-security identification file, with a clear decision date.

Finally, decide who is responsible for each action. The foreign founder may instruct an accountant, a payroll bureau or a French director, but delegation does not remove the company’s need to supervise the data. Put the responsible person, deadline, transmission channel and backup contact in writing. A board based outside France should be able to identify who could answer URSSAF, the CPAM or an inspection agent without searching through a chain of informal messages.

II. What should a foreign founder do when the DPAE is rejected?

A. How do you correct a blocked DPAE before the first working day?

Start by separating an absent French social security number from the actual rejection reason. If the employee has no NIR and no NIA, that fact is compatible with a DPAE according to URSSAF’s guidance. A rejected filing may instead relate to the employer’s SIRET, the occupational-health service, an impossible birth date, an invalid contract code, a mismatch between the establishment and URSSAF, or a technical authentication problem. Ask for the complete error wording and reference number. Do not accept a generic statement that “foreign employees cannot be filed.”

Next, identify the establishment and the recipient. Article R. 1221-3 of the Labour Code says that “La déclaration préalable à l’embauche est adressée par l’employeur” to the relevant collection body for the establishment. For a normal non-agricultural employer, that means the URSSAF body connected with the establishment that will employ the worker. The establishment address, SIRET, legal employer and occupational-health service should all point to the same employment arrangement.

Check the timeline before trying to solve the form. Article R. 1221-4 provides that the DPAE is sent “au plus tôt dans les huit jours précédant la date prévisible de l’embauche.” The French phrase means no earlier than the eight days preceding the expected hiring date. The filing must also be made before the employee starts work. If the start date is tomorrow and the portal is refusing the employee number, the employer should escalate immediately, not wait for a final NIR.

Use a short diagnostic sequence:

1. Open the legal employer’s current SIRET record and confirm that it is active and associated with the intended establishment.
2. Match the employer name, address and APE code in the DPAE to that record.
3. Confirm the competent occupational-health service and its reference.
4. Re-enter the employee’s identity from the source document, without changing spelling to satisfy an English payroll system.
5. Leave the NIR/NIA field absent when no number exists and the official route permits absence.
6. Confirm the planned date, start time, contract type, duration and probation information.
7. Save the complete error screen, timestamp, account used and every support reference.

Do not test the same form repeatedly with different invented identifiers. Repeated transmissions can create uncertainty about which declaration was accepted and may expose another person’s data. If a payroll provider’s software requires a number, ask the provider to explain whether it is validating a DPAE or a later payroll/DSN file. The DSN, or déclaration sociale nominative, is the monthly nominative social declaration; its identification requirements may not be identical to the first DPAE route.

The employer should try the official electronic route first. Article R. 1221-5 states that “La déclaration préalable à l’embauche est effectuée par voie électronique.” The same article sets out the paper alternative when the electronic route is not used: a signed form is sent to the body referred to in Article R. 1221-3 by registered letter with acknowledgement of receipt no later than the last working day before the hiring. The employer must keep a copy and the postal receipt until the receipt document arrives. The current text also says that the unavailability of one transmission method does not exempt the employer from using the other method.

This alternative is not a licence to ignore the portal or to send an incomplete letter. The paper form must contain the truthful employer, employee and contract information, and it must be addressed to the competent body. The founder should keep a copy signed by the employer, the registered-mail receipt, the delivery evidence, the portal error and the support correspondence. If the portal works but the NIR is absent, use the compliant electronic process. If the portal or authentication route is genuinely unavailable, document the reason for using the statutory paper route.

If the company has no active SIRET at all, do not confuse the legal ability to declare an employee without a NIR with the separate problem of establishing the employer’s establishment identity. The SIRET belongs to the employer’s establishment, whereas the NIR belongs to the employee. Contact the competent URSSAF with the incorporation evidence, the establishment record, the planned employment contract and the intended start date. Ask which identifier can lawfully be used while the establishment registration is pending. A registration receipt, Kbis, INPI submission reference or other document may support the exchange, but none should be substituted into a field without confirmation from the receiving body.

If the company’s registered office has recently moved, compare the old and new SIRETs and the effective date of the establishment change. A DPAE filed against an old establishment can be a different problem from a DPAE filed without a NIR. The correction should identify the employer, employee and start date, state the error precisely, and ask how the competent body wants the declaration corrected. Preserve both the original submission and the correction. Never delete the first receipt from the evidence file.

If the employee has already started, the situation becomes urgent. Make a truthful declaration as soon as possible through the correct route, state the actual start date, inform the payroll adviser and assess the social and employment consequences. Do not backdate a transmission or alter the employee’s identity to make the record appear timely. A prompt correction does not guarantee that there is no liability, but it gives the company a defensible chronology and avoids adding a false document to the original delay.

Escalation should be written, not merely oral. A useful message to URSSAF identifies the legal entity, establishment SIRET, employee’s name and birth details, planned start date and time, absence of NIR/NIA, exact portal error, attempted transmission time and requested instruction. Attach only the documents necessary for the request and protect personal information. Ask the recipient to confirm the correct channel and whether the first declaration will also initiate employer and employee registration.

B. How do you prove the filing and limit late-DPAE risk?

A successful data entry is not enough. The founder needs a receipt that identifies what was actually transmitted. Under Article R. 1221-7, the receiving body sends a document acknowledging receipt and recording the information, “dans les cinq jours ouvrables suivant celui de la réception du formulaire de déclaration.” If the employer does not contest the information within two working days after receiving that document, it constitutes proof of the declaration. The company should compare the receipt with the contract rather than filing it unread.

Pay particular attention to the employee’s name, birth data, employer SIRET, start date and time, contract type and occupational-health service. A receipt with a typo can be more dangerous than a missing receipt because it creates a false appearance of compliance. Send a correction request promptly if the wrong identity or establishment was recorded. Retain the message, the response and the new receipt together with the original.

The employee must receive evidence as well. Article R. 1221-9 provides: “Lors de l’embauche du salarié, l’employeur lui fournit une copie de la déclaration préalable à l’embauche ou de l’accusé de réception.” That means the employer gives the employee a copy of the declaration or its acknowledgement of receipt at hiring. The duty can be satisfied through a written employment contract containing the required mention of the recipient, but the founder should still give the employee a readable record of the actual filing whenever possible.

Store the receipt in a controlled compliance folder with the contract, identity document, work-authorisation check, health-service evidence, personnel-register entry and payroll mandate. The unique personnel register, called the registre unique du personnel or RUP, is mandatory in each establishment where employees work. Article L. 1221-13 states: “Un registre unique du personnel est tenu dans tout établissement où sont employés des salariés.” Record the employee in hiring order with the required information; the register is not a replacement for the DPAE, but it should tell the same story.

Occupational health also requires follow-through. Article R. 1221-2 links the DPAE to the request for the occupational-health service and the preventive health visit. Article L. 4624-1 says that the individual monitoring includes “une visite d’information et de prévention effectuée après l’embauche.” The employee without a NIR still needs the appropriate health process. Keep the appointment request, the service’s response and the resulting certificate or medical document in the proper confidential file.

The employer should then prepare the first payroll and the monthly DSN using the identifier information that is actually available. Ask the payroll provider how the employee is represented while CPAM identification is pending, how later receipt of the NIR will be added, and how a correction will flow into the next DSN. The answer should be written into the payroll instructions. A foreign parent should never let a provider silently replace the employee’s missing number with a technical dummy value.

Employer registration is a separate part of the first-hire chain. Article R. 243-2 of the Social Security Code addresses the delivery and communication of the employer’s registration number to the relevant bodies. The company should reconcile the employer number, SIRET and URSSAF account. If the legal entity is a French subsidiary, the parent’s foreign tax or social-security number should not be presented as the French employer’s registration. If the legal employer is the foreign company, confirm the special cross-border route before sending a French subsidiary’s identifiers.

The legal exposure of a late or absent DPAE should be described accurately. Article L. 1221-11 provides an administrative penalty when non-compliance is observed by the competent control agents. Its text refers to “Le non-respect de l’obligation de déclaration préalable à l’embauche.” The amount and collection mechanism should be assessed under the applicable provisions and facts; a founder should not rely on an outdated online calculator.

The more serious concept is concealed employment. Article L. 8221-5 describes concealed salaried employment where an employer “se soustraire intentionnellement à l’accomplissement de la formalité prévue à l’article L. 1221-10.” The word “intentionnellement” matters: a missing NIR is not the same as an intentional decision to hide employment, and an isolated technical error is not automatically a criminal conviction. It remains important to correct quickly because the company must be able to show the contract, the attempted filing, the error, the alternative transmission and the payroll record.

The potential criminal penalty is stated in Article L. 8224-1, which provides that violating the prohibitions in Article L. 8221-1 is punished by three years’ imprisonment and a fine of €45,000. This statement should not be applied mechanically to every late form. The legal classification, the employer’s intention, the reality of the work and the evidence all matter. A foreign board should obtain advice immediately if the employee worked before any declaration, if several employees are affected, or if the payroll provider created inaccurate records.

French case law illustrates why the evidence must be concrete. In its decision of 28 May 2013, Criminal Chamber, no. 11-87.775, the Cour de cassation held that the lower court’s reasons did not “caractérisent les éléments constitutifs des infractions retenues.” The official decision, no. 11-87.775, shows that a court must identify the facts and legal elements supporting the offence; a label such as “late DPAE” cannot replace that analysis. For the founder, this is not a reason to relax compliance. It is a reason to preserve the actual chronology and the exact role of each person.

In its decision of 26 November 2020, Second Civil Chamber, no. 19-24.303, the Cour de cassation approved a social-contribution adjustment where the facts showed services performed in conditions “caractérisant l’existence d’un lien de subordination juridique.” The official decision, no. 19-24.303, concerns the relationship between the work performed, the legal subordination and the URSSAF adjustment. It reinforces the practical point that an employer should not rely on a consultant label, foreign ownership or an English payroll contract when the day-to-day relationship is salaried.

Cross-border documents do not automatically displace French filing duties. In its decision of 12 January 2021, Criminal Chamber, no. 18-80.035, the Cour de cassation stated that “l’existence de certificats E101 et A1 ne fait pas obstacle à une condamnation.” The official decision, no. 18-80.035, concerned European social-security certificates: E101 is the historic certificate and A1 is the portable document identifying applicable social-security legislation. The case does not say that every foreign worker belongs to the French regime. It does show why a foreign company must classify the cross-border arrangement instead of treating a foreign certificate as a universal substitute for a DPAE.

If an inspection agent asks for proof before the acknowledgement arrives, Article R. 1221-12 requires the employer to present the receipt when it must still be retained or to communicate the elements showing that the DPAE was made. A foreign founder should therefore keep the transmission timestamp, confirmation screen, email, registered-letter evidence, support ticket and correction history in a single chronological file. The file should be understandable to a French reader even if the parent company’s board papers are in English.

Use the following post-filing reconciliation before the first payslip:

• the contract’s legal employer matches the DPAE’s employer;
• the establishment SIRET matches the place of work and the occupational-health service;
• the employee’s name and birth details match the identity document;
• the missing NIR/NIA is recorded as missing, not replaced with a dummy value;
• the DPAE receipt shows the correct start date and time;
• the employee received the required copy or contract mention;
• the RUP entry is dated and consistent with the hiring;
• the CPAM identification follow-up is assigned to a named person;
• the health-service request and preventive visit are tracked; and
• the first payroll and DSN instructions explain how the later French number will be added.

This record also protects the foreign founder against a recurring administrative failure: the parent company believes that a payroll bureau has completed the filing, while the bureau believes that the French director or the parent’s finance team will supply the missing identity information. The mandate should state who transmits, who receives the receipt and who corrects a rejected declaration. A service agreement is useful, but it does not turn an unverified email into proof of a DPAE.

If the employee later receives a NIR, update the payroll and social records through the proper channel, preserve the original no-number DPAE, and keep the CPAM correspondence showing the link between the temporary file and the final identifier. Do not create a second employment start date merely because the identifier changed. If the employee’s name, birth data or legal identity was wrong in the first filing, ask the receiving body how to correct the historic record and record the correction date.

For a company working with several foreign employees, standardise the process without standardising the identifiers. The checklist can be the same, but every NIR, NIA, passport record, date of birth, employer and establishment must be individual. The compliance manager should sample the receipts, compare them to the contracts and confirm that no dummy values appear in the payroll export. The foreign board should receive an exception report listing only actual blockers: no SIRET, wrong establishment, rejected transmission, missing work authorisation, unresolved identity mismatch or absent receipt.

Conclusion

A foreign founder does not need to wait for a French social security number before filing a DPAE for an employee who has no NIR or NIA. The official URSSAF position is that the declaration is still taken into account. The compliant approach is to enter accurate identity data, leave an unassigned number absent through the authorised route, and allow the DPAE to support the employee’s subsequent CPAM registration. The employer must still resolve the separate questions of the legal entity, establishment SIRET, occupational-health service, work authorisation and payroll route.

When a DPAE is rejected, treat the error as a diagnosis problem. Check the employer and establishment fields, verify the recipient, respect the eight-day window and preserve the timestamp. If the electronic route is genuinely unavailable, use the signed registered-letter route provided by Article R. 1221-5 and keep every receipt. If work has already started, make a truthful urgent correction and obtain advice on the consequences. The best evidence is a chronological file that shows what the company knew, what it transmitted, what failed and what it did next.

The practical test is simple: can the company show the employment contract, identity document, DPAE transmission, receipt or alternative proof, employee copy, RUP entry, health-service evidence, payroll instruction and CPAM follow-up without reconstructing the file after an inspection? If the answer is no, the foreign parent and French management should close that gap before the next hire.
