If you are an EU, EEA or Swiss citizen registering as a resident in Spain, you may need to prove healthcare cover as part of your Certificado de Registro (the green certificate / green NIE). This is a practical checklist of what your health insurance actually needs to show — who needs it, who does not, how S1, EHIC and GHIC fit in, and the documents to bring to your appointment. For plans, prices and quotes, see our main EU residency health insurance in Spain page.
The requirement
EU, EEA and Swiss citizens who plan to live in Spain for more than three months register on the Central Register of Foreign Nationals and receive the green certificate (Certificado de Registro de Ciudadano de la Unión). For economically inactive citizens — retirees, students, early retirees and people living from savings — registration usually requires proof of comprehensive healthcare cover plus sufficient resources.
That healthcare proof can be private health insurance, a registered S1, or accepted Spanish public healthcare. This page sets out exactly what each option needs to show. For plans, prices and quotes, use our main EU residency health insurance in Spain page.
Who needs it
Healthcare proof is generally required for economically inactive EU citizens who are not covered through work or an accepted public route. This typically includes:
Some applicants rely on public healthcare or exported rights instead of buying a private policy. This often applies to:
Who needs cover — at a glance:
| Your Situation | Healthcare Proof Usually Used | Private Insurance Needed? |
|---|---|---|
| Retiree, no S1 yet | Private health insurance | Yes, usually |
| Retiree with registered S1 | Exported public healthcare (S1) | No, where S1 is accepted |
| Student not covered another way | Private health insurance | Yes, usually |
| Living from savings / early retiree | Private health insurance | Yes, usually |
| Employee paying Spanish social security | Spanish public healthcare | No |
| Registered autónomo | Spanish public healthcare | No, where accepted |
| Non-working spouse / family member | Private cover or beneficiary route | Often, unless covered another way |
Key requirements
Where private insurance is your healthcare proof, this is the part that matters most. The policy should normally provide:
No-copay?
No-copay (sin copago) is generally the cleaner and stronger option for residency registration, because it looks more like comprehensive healthcare cover with nothing for you to pay per visit. Some local offices may be stricter than others and effectively expect it. A copay policy can be more affordable but may invite questions when used as your main residency proof.
EHIC / GHIC / S1
This is where a lot of confusion happens, because these documents are often mixed up. Here is how each one fits — or does not fit — EU residency registration:
| Document | What It Is For | Use for EU Residency Registration |
|---|---|---|
| EHIC | Temporary stays and emergencies within the EU | Not suitable for permanent residency registration |
| GHIC | Mostly UK temporary healthcare needs | Not suitable for EU residency for most post-Brexit UK nationals |
| S1 | Exported healthcare rights for eligible retirees / posted workers | Accepted where registered, as public-healthcare proof |
| Private health insurance | Living in Spain as an economically inactive resident | Suitable where comprehensive and active from the date needed |
The European Health Insurance Card covers temporary stays and emergencies within the EU. It is not designed for someone moving permanently, so it is not normally accepted as residency healthcare proof.
The UK Global Health Insurance Card mainly covers temporary healthcare needs. For most post-Brexit UK nationals it is not suitable for registering as a Spanish resident.
An S1 exports healthcare rights for eligible retirees and certain posted workers. Where registered and accepted, it serves as public-healthcare proof. Many people take out private insurance to cover the gap while waiting for an S1 to be issued and registered, then rely on the S1 once it is active. Local offices keep some discretion over what they accept.
Certificate
If you are using private insurance, the certificate (certificado de seguro) is the document the office actually checks. It should clearly show:
Documents
Health insurance is one part of the green-certificate appointment. The application form is the EX-18, and the healthcare proof sits alongside your identity and resources documents. A typical document set is:
Families
Family situations are where requirements most often get missed. Each person in the application generally needs healthcare proof, and mixed situations are common. Check:
Rejection risks
Most problems at the appointment come from the same handful of issues. Avoid these and the healthcare step is usually straightforward:
If private is needed
If private insurance is your route, you only need a comprehensive no-copay policy that is valid in Spain and documented properly — not a premium visa-style product. For EU residency we point people to the two no-copay Sanitas plans:
Más Salud Sin Copay the no-copay plan for individuals.
Más Salud Familias Sin Copay the family version, where you are covering a household.
Both are comprehensive, no-copay and come with a Spanish certificate suitable for the green certificate. For prices, comparison and to request a quote, see our EU residency health insurance quotes page.
This page covers the requirements. For prices, plan comparison and a quote, head to our main EU residency page — or message an English-speaking adviser to check your route first.
