Many entrepreneurs believe FranceConnect+ is mandatory by INPI. It's a misconception. The Guichet Unique requires an eIDAS qualified signature, period. FranceConnect+ is ONE way to obtain it; others exist, legally equivalent, that don't require La Poste Digital Identity, physical visit, or dependence on a regularly failing public service.
This article details the complete method to sign on INPI without FranceConnect in 2026.
Why avoid FranceConnect+?
- The service crashes regularly: blank page, orange banner, loading loop. See FranceConnect+ doesn't work.
- Your La Poste Digital Identity was rejected or its level is insufficient.
- You live abroad: no accessible French post office for physical certification.
- You're in a hurry: creating a La Poste Digital Identity takes 2 to 5 days.
- You don't want to depend on a State service that can fail at the worst moment.
In all these cases, the alternative route exists and works.
The legal principle: eIDAS, not FranceConnect+
The European eIDAS Regulation 910/2014 defines the qualified electronic signature as a signature with a certificate issued by a qualified provider listed on the EU Trust List. This definition is technologically neutral: it doesn't mention FranceConnect+ or La Poste Digital Identity.
The INPI Guichet Unique strictly applies this definition. When it verifies a signed PDF, it only looks at:
- Is the certificate on the EU Trust List?
- Is the cryptographic level qualified (QC / QSCD)?
- Is document integrity preserved?
If you sign via Universign, Yousign Pro+, Certigna or any other qualified route, the result is strictly identical in INPI's eyes. The Guichet Unique gives no preference to FranceConnect+.
The complete method to sign without FranceConnect+
Step 1 — Complete your formality up to the signature step
On procedures.inpi.fr, follow the normal flow of your formality. You arrive at the "Signature of the summary" step.
Step 2 — Download the PDF summary instead of clicking FranceConnect+
On the signature screen, the Guichet Unique generally offers:
- A "Sign with FranceConnect+" button (the standard route).
- A "Download summary" link (what we want).
- An "Upload signed file" button (to re-upload a PDF signed elsewhere).
Click "Download summary". Save the PDF without opening it in Adobe Reader. See detailed tutorial.
Step 3 — Have the PDF signed by a qualified provider
Several options depending on your profile:
- Individual / SME / one-off formality → SignerSynthèse.fr (€29 ex. VAT pay-as-you-go).
- Accounting firm / lawyer → Yousign Pro+ or AR24 pack (€10-25/signature).
- Large structure with API need → Universign direct or DocuSign Business Pro.
For SignerSynthèse.fr, the journey is:
- Upload the PDF summary on the home page.
- Fill in identity (name, email, phone).
- Pay €29 ex. VAT (Visa, Mastercard, Amex, Apple Pay, Google Pay).
- Verify identity by ID photo + selfie + SMS (Universign PVID journey).
- Receive the signed PDF by email in 2 minutes.
Step 4 — Re-upload the signed PDF on the Guichet Unique
Go back to procedures.inpi.fr. On the signature screen, click "Upload signed file" (instead of FranceConnect+). Upload your qualified-signed PDF. The Guichet Unique cryptographically verifies the signature and validates the formality instantly.
Without FranceConnect+: €29 ex. VAT, 2 minutes.
eIDAS qualified signature via Universign (EU Trust List). 100% accepted by the INPI Guichet Unique.

Use cases where the without-FranceConnect+ route is mandatory
1. You live abroad
For a French expat needing to sign a business cessation or articles amendment, the FranceConnect+ route is impractical (no accessible post office). The remote qualified route is the only option.
2. You manage multiple companies
For a holding director needing to sign 5 articles amendments in parallel, the pay-as-you-go qualified route allows signing everything in 30 minutes. With FranceConnect+, expect several hours of retries in case of failure.
3. Your La Poste Digital Identity was rejected
If the La Poste app refuses your identity (poor photo quality, unrecognised document, failed verification), the FranceConnect+ route is closed to you. See La Poste Digital Identity rejected.
4. The service is down and you have a tight legal deadline
For an articles amendment to be filed within one month of the AGM, or annual accounts at legal limit, you can't wait for FranceConnect+ to come back online.
FAQ
Is the PDF signed without FranceConnect+ actually accepted by INPI?
Yes, at 100%. The Guichet Unique checks the cryptographic level of the certificate, not the obtaining route. A Universign signature is worth a FranceConnect+ signature.
Can I verify my signature before uploading?
Yes. Open the signed PDF in Adobe Reader, right-click the signature → "Properties". You should see: level "QES / Qualified Electronic Signature", issuer in the French qualified providers list.
Is there a risk INPI changes its mind on alternative providers?
Very low. eIDAS compliance is guaranteed by European regulation, which prevails over French law. INPI cannot legally prefer FranceConnect+ over other qualified routes.
How much does the without-FranceConnect+ route cost for 5 formalities/year?
5 × €29 = €145 ex. VAT for 5 pay-as-you-go signatures. That's cheaper than a Yousign Pro+ subscription or DocuSign Business Pro.
Conclusion
FranceConnect+ is not mandatory for signing an INPI Guichet Unique formality. You can perfectly do without it using a qualified eIDAS provider listed on the EU Trust List. The legal result is identical, the procedure is faster (2 minutes vs 2 days), and you avoid public service outages.
For 99% of cases, the without-FranceConnect+ route is even more practical than the official route. It has become the standard for hurried directors and expats.
