How to Obtain the S1 Form in France
Obtaining the Form Through Your French Health Insurance Fund
- Request through your ameli account: Log in to your personal account, access the messaging section, and select “Request an S1 form.”
- Contact your CPAM: Your local Primary Health Insurance Fund (CPAM) issues the document if you are a pensioner, posted worker, or student.
- Apply through the MSA: Individuals covered by the agricultural scheme must contact their Mutualité Sociale Agricole (MSA) directly.
- Variable processing times: Each application is reviewed individually; expect several weeks depending on the complexity of your situation.
- Transmission to the host country: Once approved, your S1 is sent by the CPAM to the competent healthcare institution in your country of residence (EU/EEA/Switzerland).
Specific Procedure for UK Pensioners
- Contact NHS Overseas Healthcare Services: Recipients of a UK state pension must contact the NHS Overseas Healthcare Service by phone to start the application process.
- Provide proof of your UK pension: You will need your UK National Insurance number and evidence that you receive a pension.
- Issued by the UK authorities: The form is issued by the Department for Work and Pensions (DWP).
- Valid for use in France: The S1 allows you to register with the CPAM and receive healthcare coverage under the same conditions as French residents.
- Post-Brexit protection: The Withdrawal Agreement preserves these rights for pensioners covered before the end of the transition period.
Registering and Validating the S1 with the CPAM

Once you have obtained your S1 form, the next step is to register with your local CPAM (Primary Health Insurance Fund). This administrative process is essential to activate your healthcare rights and begin receiving reimbursements for medical expenses in France.
- Visit ameli.fr: Log in to your personal account through the official French Health Insurance website. This is the main platform for starting your registration process.
- Provide proof of identity: Submit a copy of both sides of a valid national identity card or passport.
- Submit proof of address: A document dated within the last three months is required (electricity bill, gas bill, rent receipt, etc.) to prove your residence in France.
- Provide bank account details (RIB): Submit a French bank account statement (RIB) so that reimbursements can be deposited directly into your account.
- Receive a temporary social security number: Once your application is approved, the CPAM will assign you a temporary French social security number, allowing immediate access to healthcare coverage.
After submitting these documents, you will receive a temporary certificate of entitlement, which serves as proof of coverage while your application is being finalized. For most EU citizens, certified translations of documents are generally not required, except in certain cases involving countries such as Greece or Bulgaria. Students may complete registration through the dedicated portal etudiant-etranger.ameli.fr, where a certificate of enrollment or student card is often sufficient. Completing these steps ensures a smooth and efficient validation of your S1 form and access to healthcare services in France.
What Is the S1 Form?
The S1 form is a portable document that allows you to access healthcare in another country within the European Union, the European Economic Area, or Switzerland. It enables you to register with the health insurance institution in your country of residence while remaining covered by the healthcare system of your home country.
This document is mainly intended for pensioners, posted workers, and students living outside their home country. It replaces older forms such as the E106, E109, E120, and E121. It remains valid as long as you continue to meet the eligibility conditions under which it was issued.
The S1 covers healthcare and maternity benefits in kind. Once registered, it entitles you to receive healthcare under the same conditions as residents of your host country, often without having to pay medical costs upfront.
