France INPI Guichet Unique Filing for Foreign Businesses: Routes, Tracking & Regularization

For an INPI Guichet Unique foreign business filing in France, the first practical question is which route describes the filer. A foreign individual helping create a French company is not the same applicant as an overseas company registering a French branch, and both differ from a foreign business with no French establishment. INPI operates the national online portal, but the authority that reviews the declaration depends on the business and its activity.

Key takeaways

Choose the route before translating documents. A French company with foreign founders generally follows the French company creation route; a foreign legal entity registering a branch follows a branch route; some foreign businesses without a French establishment are routed to tax or social-security authorities.
INPI is the portal operator, not a universal approver. The reviewing authority may be a commercial court registry (greffe), DGFiP, URSSAF, MSA, or CMA, depending on the case. INPI lists the competent authorities by activity and business situation.
A regularization request needs action inside the original filing. The portal says the reviewer’s processing clock pauses; you must make the requested changes in the form, provide requested documents, and sign the declaration again. No action within 15 days leads to automatic rejection. See the official status instructions.
Do not assume every foreign attachment needs a sworn translation. Prepare a French translation when the route or reviewing authority requires one. Confirm whether it must be by a court-listed traducteur agréé; a generic English-language certified translation may not meet that requirement.

Who this guide is for

This France-wide guide is for foreign founders creating a French company, overseas company representatives registering a French branch, and accountants, lawyers, or other authorized agents filing or correcting those declarations. An English-to-French packet is a useful working example; the same routing questions apply to records in other languages. Typical files may include a passport, proof of address, French company statutes, a foreign company registry extract, proof of authority to represent the company, and evidence of a French business address. It is most useful when you are unsure which route applies, cannot tell which authority is reviewing the file, or have received a French-language régularisation notice with a deadline.

Scope: the filing and correction lifecycle

This article focuses on the Guichet unique process: route selection, authority handoff, status tracking, regularization, and what to do after rejection. It is not a full guide to choosing a French legal form, tax planning, immigration eligibility, or every step needed before incorporation. For the legal distinction between a foreign company’s branch and subsidiary, see France: foreign-company branch vs. subsidiary. Foreign document authentication is a separate question; see the guide to apostille and legalization order.

Start by identifying the right filing route

The Guichet unique is a national digital gateway. France has no separate city or regional Guichet unique rules; the main difference is which authority receives and reviews the filing. The answer turns on the legal entity, activity, whether there is an establishment in France, and whether the foreign business employs people in France.

Situation	Likely route and reviewer	Practical distinction
A foreign individual or group creates a new French company, such as a SAS or SARL	French company creation. Commercial companies and commercial activity are generally reviewed by the competent greffe; activity-specific rules can change the validator.	The company is French even if its founder or shareholder is foreign. Do not select a foreign-company branch route just because the owners live abroad.
An existing overseas company registers a branch with a French establishment	Branch declaration, routed according to the French establishment and the activity to the competent validator, commonly a greffe for commercial filings.	This is a filing by the existing foreign legal entity. The portal may request current foreign company records, representative authority, and French establishment details.
A foreign business has no French establishment and no French employees	INPI identifies DGFiP as the validator for foreign enterprises in this category, across activities.	This is a special foreign-business route. It should not be filed as an ordinary French company creation merely to obtain a French tax identifier.
A foreign business has no French establishment but employs staff in France	For non-agricultural activity, INPI identifies URSSAF; for agricultural activity, MSA.	Employee and activity details affect the recipient. Follow the route generated by the portal and check the receiving body shown in the record.
Artisanal, agricultural, or individual liberal activity	Depending on the activity and form, the validator may be CMA, MSA, or URSSAF.	Describe each activity accurately. The portal’s activity classification and your legal form help drive the handoff.

These are routing guides, not a substitute for the case-specific destination displayed by the portal. For example, a French company with a foreign shareholder is not automatically routed like a foreign company without an establishment. The official INPI validator list is the best starting point when your activity or establishment situation is unusual.

How to file through the Guichet unique

Describe the entity and purpose accurately. Decide whether the filing creates a French company, registers an existing foreign company’s branch, or concerns a foreign company with no French establishment. Do not use the first route that looks familiar: the answers determine the checklist and destination.
Use the portal-generated document list. The required documents depend on the route and the answers in the form. A French company creation may involve identity and address documents, statutes, proof of the registered address, capital-deposit evidence, and publication evidence. A branch may involve the foreign company’s current registry extract and statutes, proof of the French establishment, and documents showing who can act for it. These are examples, not a universal checklist.
Check names and authority across the packet. Compare the company’s legal name, registration number, registered address, director names, dates, and signing authority in each record. If a representative or professional files for the business, keep the signed mandate and ensure it covers the relevant formality.
Complete the online form, payment step if applicable, and signature. Creation, modification, and cessation can have different signing prompts. Current INPI guidance says simple electronic signature is sufficient for creation; for a modification or cessation, the options include an advanced electronic certificate or a simple signature after strong authentication with FranceConnect+. Follow the instructions for the actual filing, especially if you are correcting a declaration rather than making a new one. INPI’s FAQ covers account access, signature options, fees, and filing follow-up.
Save the submission record and follow the dashboard. The portal dashboard is the record of the filing’s status and the reviewer’s request. Keep the submission summary, payment record, and any notice. A filed declaration is not yet an approval or proof that a Kbis is ready.

If you are unsure whether the proposed operation is a branch or subsidiary, pause before submitting and get advice on the business structure. The filing route and the underlying legal choice are related, but the Guichet unique does not make that choice for you.

Which documents need French translation?

For foreign-language company records, the useful French term is traduction en français. The phrase “certified translation” helps international applicants describe a professionally certified translation, but it is not a single France-wide credential that guarantees acceptance by every validator. The portal checklist and the authority reviewing the record control what must be translated and what form the translation must take. For a France-specific document discussion, see translation of foreign company records in France.

For a foreign branch, foreign statutes and registry extracts may need French versions for the filing. In a separate tax-registration route, DGFiP may have its own instructions for foreign statutes. Do not transfer one authority’s document rule to every Guichet unique route. If a notice specifically asks for a traduction assermentée or traducteur agréé, use the requested standard. In France, a traducteur agréé is a judicial expert listed by a Court of Appeal or the Court of Cassation; Service-Public explains how to find one.

Where the receiving authority accepts a standard certified translation, make sure the full record is translated, including headings, stamps, annotations, seals, and relevant handwritten notes. Keep the company’s registered name and registration number consistent rather than silently replacing them with a translated or phonetic version. A clear page-by-page layout helps the reviewer match the French text to the source. Ask the recipient whether a sworn translator is required before ordering; extra certification does not cure a wrong route or missing corporate authority document.

Translation and authentication are different steps. An apostille or legalization authenticates a public document or signature chain; it does not translate the document. The required order depends on the source document and the issuing country. Use the linked France foreign-company document authentication guide for that separate question.

Read the status labels and act on the record

After signature, the declaration is transmitted to the relevant recipient or recipients. In the dashboard, the labels describe different next actions:

En brouillon: the form is saved but not submitted. Continue or remove it.
En attente de paiement: payment of any applicable statutory fee is still due.
En attente de signature: the declaration has not been sent to the destination authorities. Signing is the submission action.
En cours de validation: the recipients are reviewing the filed information and attachments. The declaration is not normally editable at this stage.
En attente de régularisation: a reviewing body says the filing is incomplete, needs a correction, or needs supporting evidence. The reviewing body’s validation clock pauses while you respond.
Validée: the formalities have been validated and the relevant registers are updated.
Rejetée: that declaration did not create the requested new entry in the relevant registers. Review the reason and decision-maker before choosing the next step.

The official status guide says a regularization must be made in the original filing form. Add or correct the requested information, attach the documents asked for, then sign the complete declaration again. Depending on the correction, additional statutory fees may be due. Uploading a document without completing the new signature does not finish the response.

Do not treat an email as the entire record. Use it as a prompt to log in, open the dashboard, read the reviewer’s exact request, and note the deadline shown. While a filing is under validation, you generally cannot add an unsolicited attachment; wait for a regularization request or ask the named competent authority how it wants the issue handled.

Regularization, rejection, and a portal outage

When a filing enters En attente de régularisation, start by identifying who issued the request and what it asks for. Is the issue an untranslated foreign record, a missing page, inconsistent company name, incomplete authority chain, or an incorrect activity classification? Respond to the stated problem rather than replacing the whole packet with unrelated documents.

The Guichet unique states that if the filer takes no action within 15 days, the declaration is automatically rejected. The status page does not make that a generous translation window: if a missing French version may be requested, identify the recipient’s translation standard before the first submission and keep source files ready. When the notice is unclear, contact the authority named in the record promptly. INPI Direct can help with portal operation, but it cannot reverse a substantive decision made by a greffe or another validator.

If the status becomes Rejetée, read the decision and its stated reasons. The official instructions identify two broad options: challenge the decision through the competent legal channel within the applicable legal deadline, or make a new filing. The right choice depends on the reason and the decision notice; do not assume an appeal deadline or send a complaint to the technical help desk instead of the decision-maker.

A portal failure does not mean you should mail a paper packet to a guessed address. The official Guichet unique FAQ says that an alternative procedure may be offered depending on the malfunction and the formality. Start with the official portal and follow the instructions shown for your case; do not assume that email or an ordinary paper filing is an approved substitute.

Timing, fees, and the numbers to calendar

There is no guaranteed completion date for every foreign-business filing. Processing time depends on the formality and reviewing authority. INPI’s general information gives an average of roughly two weeks for a SIREN number, but that is not a service-level guarantee for a foreign-company route and does not predict when a competent greffe will issue a Kbis. A SIREN is issued after validation; the competent greffe supplies the Kbis. Check the current INPI guidance for status, SIREN, Kbis, and fees.

The Guichet unique itself is a free public service; some filing types still carry statutory fees set by the relevant rules. The amount depends on the filing and is displayed during the payment step. A paid accountant, lawyer, formaliste, chamber, or translation provider charges separately for its own service. Ask for a clear scope and price, and distinguish a professional’s service charge from the government fee.

15 days: the response period stated for an unanswered regularization request before automatic rejection. Calendar this from the notice and follow the deadline displayed in your case.
About two weeks: a general SIREN average reported by INPI, not a foreign-filing promise and not a Kbis deadline.
Three years: the status guide says an archived, validated declaration remains consultable on the portal for three years. Download records you need for longer retention.

Common friction points and field reports

Choosing the route by nationality rather than legal entity. A foreign founder can create a French company; that does not turn the filing into a foreign company branch registration.
Confusing the portal operator with the reviewer. The dashboard can show a reviewer-specific status. Contact the body that issued a content request, and reserve INPI Direct for portal and general process help.
Assuming a saved correction has been resubmitted. The status instructions require a new signature after regularization. Check the dashboard afterward to confirm that the declaration returned to validation.
Waiting to discover a language or identity issue. A foreign-language registry extract, company statute, or mandate may take time to translate; a foreign representative may also need to check the portal’s authentication and signature options early.

Individual user reports illustrate these frictions but do not measure how often they occur. On the government’s Services Publics+ feedback site, one filer in Morbihan described a creation file held for regularization despite believing the activity had already been validated by the CMA; INPI’s reply described its role as operating the portal and transmitting filings to competent bodies. A separate Reddit discussion by a non-French resident concerned a later modification and the difficulty of completing an advanced signature, not an initial company creation. These accounts support a practical habit—check the exact dashboard status, reviewer, and signature step—but they are not official rules or evidence of a typical processing time.

France-wide support and provider options

The rules are national, while support depends on the problem. Ordinary business formalities are submitted online; there is no city office to visit for routine filing. If you need help, identify whether you have a technical issue, a filing-content question, a legal-structure question, or a translation requirement.

Public or official resource	Use it for	Boundary
Guichet unique dashboard and help tools	Submitting, seeing the recipient’s status, reading a regularization notice, and checking payment or signature actions.	The portal record is the starting point for an in-progress declaration.
INPI Direct: +33 (0)1 56 65 89 98, weekdays 9:00–18:00	Technical access and general questions about using the portal or form.	It does not replace the authority reviewing the filing or provide a remedy against its decision. Contact details and support scope are on the official assistance page.
CCI, CMA, or agricultural chamber	Free general assistance tied to the activity and its formalities; useful when classifying an activity or understanding the process.	More hands-on assistance may be offered for a disclosed fee. It is optional, not a government filing charge.
Competent reviewer shown in the case	Questions about the substance of a correction or rejection from the greffe, DGFiP, URSSAF, MSA, or CMA.	Use the decision or request to identify the correct body; the portal help line cannot change the reviewer’s decision.

Check fee requests and route complaints correctly

The official portal is free to use, although a filing can have statutory charges. A private formaliste or adviser may also charge for optional help; the government distinguishes that professional service from use of the Guichet unique. Start at the official government portal and review any amount at the payment step. If a third party describes its own fee as a mandatory portal-access charge or promises guaranteed approval, verify the claim before paying and ask for the provider’s identity, written scope, and any mandate. This is a precaution, not a claim that every paid service is improper.

For a technical failure, contact INPI Direct. For activity classification or process guidance, ask the relevant chamber. For a content request or rejection, use the reviewer and decision details in the dashboard; formal challenges follow the deadline and route stated in the decision. A technical hotline is not an appeal channel.

Commercial translation and filing support

These are different paid services, not government endorsements. A translation provider prepares language deliverables; a mandataire or professional adviser may prepare or submit a form under an appropriate mandate. Neither should promise approval by a reviewer.

Service route	When it may fit	What to confirm first
CertOf online translation service	Foreign statutes, registry extracts, identity records, or mandates needing a clear translation in a supported language pair.	Confirm the language pair, document scope, delivery format, revision terms, and whether the recipient specifically requires a France-listed traducteur agréé. A CertOf certified translation is not automatically the same as a French sworn translation. Review CertOf’s translation quality process and who signs its translation certificate, or submit a translation order.
France-listed traducteur agréé	Use when the reviewing authority or the document’s intended use calls for a sworn translation by a French judicial expert.	Confirm the expert is listed for the required language and ask what source copy and certification form are needed. The Service-Public directory explains how to find a listed translator.
Accountant, lawyer, or formaliste acting as mandataire	Useful when the hard question is route selection, activity classification, corporate authority, or portal completion—not language alone.	Ask for the written mandate, exact tasks, fee, and which filings or corrections are included. Legal, tax, and filing advice is outside CertOf’s translation role.

For a question about CertOf’s document-translation scope, use the contact page or visit CertOf. Share the exact receiving authority and any wording from its notice so the appropriate translation type can be discussed. Do not send a translation order on the assumption that a certified translation will satisfy a sworn-translation requirement.

Frequently asked questions

Does INPI review and approve my foreign-company filing?

INPI operates the portal and routes the declaration. The competent reviewer depends on the case: for example, the commercial greffe, DGFiP, URSSAF, MSA, or CMA. The dashboard and any request or decision show which authority is handling the file.

Does a French company with foreign founders use the same route as a foreign company branch?

No. The first is a French company creation with foreign founders or shareholders. A branch filing is made by an existing foreign company for its French establishment. A foreign business with no establishment may have a distinct DGFiP or URSSAF/MSA route. Choose based on the entity and activity, not the nationality of an owner.

What does En attente de régularisation mean?

A reviewing authority says the declaration needs a correction or additional evidence. Open the original filing in the dashboard, answer the request, attach what it asks for, and sign again. The official instructions say an unanswered request leads to rejection after 15 days.

Can I email a missing document after I submit?

Do not assume an email adds a document to the active declaration. During validation, the contents are not editable. When the reviewer opens a regularization stage, make the requested change in the original form and complete the new signature. If the notice directs you elsewhere, follow its instructions and retain a copy.

Do foreign company documents need a French sworn translation?

There is no safe blanket answer that every foreign attachment on every Guichet unique route must be sworn. A French version may be requested, and the reviewer or specific filing can require a traducteur agréé. Check the exact notice or ask the competent authority before choosing a provider.

How do I track an INPI business filing in France?

Log in to the Guichet unique and open the Suivre dashboard. Read the status and the status of each validator. After validation, the SIREN is communicated through the portal; the competent greffe provides a Kbis when applicable. A general average is not a guaranteed date for either result.

Is the Guichet unique free, and can a regularization cost more?

Using the public portal does not itself add a platform surcharge, but statutory filing charges may apply. The payment step displays the amount for that formality. The status instructions also warn that some corrections can require additional fees. A private professional’s charge is separate.

What should I do if the portal is unavailable?

Start at the official portal and follow any alternative procedure it presents for your formality. Do not mail a packet to an unverified address or assume that email completes a filing. For a technical problem, contact INPI Direct through the official assistance channel.

What happens if the declaration is rejected?

Read the decision in the dashboard to identify the reason and decision-maker. The official status guidance allows a new filing or a challenge through the competent legal channel within the applicable deadline. If the rejection is substantive, contact the authority named in the decision or obtain qualified legal advice; INPI Direct handles portal support, not appeals.

Prepare the translation before the deadline starts

For a France filing, the best translation preparation begins with the route: identify the likely reviewer, confirm whether the foreign company record needs French, and ask whether a court-listed translator is required. Then provide a complete, legible source file and check that names, registration numbers, addresses, dates, and representative authority match throughout the packet. If you need document translation in a supported language pair, submit the files to CertOf for a scope check or contact the team. CertOf can help with translation and document presentation; it does not choose your French business structure, provide tax or legal representation, submit your Guichet unique filing, or guarantee that an authority will accept a translation.

Disclaimer: This guide is general information about France’s Guichet unique workflow, not legal, tax, or incorporation advice. Portal instructions, fees, and authority routing can change. Follow the checklist and deadline attached to your own filing and confirm any translation credential with the authority that will review it.
