EU Citizen Registration Spain 2026: Green Certificate

What the green certificate actually is

The certificado de registro de ciudadano de la Union, commonly shortened to the green certificate or still called the “green NIE” by long-time expats, is the document that proves an EU, EEA, or Swiss citizen is formally registered as a resident of Spain. It is a small green A4 sheet, not a plastic card, and it carries your name, nationality, address, and NIE number.

This certificate exists because EU citizens exercise a treaty right to live and work anywhere in the Union; Spain is not “granting” you residency the way it grants a visa to a non-EU national, it is registering a right you already hold. That distinction matters for almost everything downstream: the process, the documents, and the card versus paper distinction all follow from it.

Unlike a passport or a TIE card, the green certificate has no expiry date. You do not renew it on a schedule; you would only request a replacement if it is lost, damaged, or your registered details change, for example a change of address.

Who must register, and by when

The 90-day threshold is the rule to remember. If you are an EU, EEA, or Swiss citizen visiting Spain for less than 90 days, you do not need to register at all; you are exercising ordinary freedom of movement as a visitor. Once you intend to actually live in Spain past that point, registration becomes mandatory, regardless of whether you are working, retired, studying, or simply relocating with savings.

This applies whether you are moving for a job, starting a business as autonomo, enrolling in university, or retiring on the Costa del Sol. It does not apply to short-term property owners who spend a few weeks a year in Spain and remain registered elsewhere; the obligation is tied to genuine residence, not property ownership or occasional visits.

Documents you need

• Valid passport or national ID card
• Completed EX-18 application form
• Proof of the reason for residence: employment contract, autonomo registration, university enrollment letter, or evidence of sufficient means for non-workers
• Private or public health insurance policy valid in Spain, if you are not covered through employment or Spanish social security
• Proof of address, generally an empadronamiento certificate or a rental contract
• Payment of the small government tasa

Non-EU family members of an EU citizen do not apply for this certificate themselves. They apply separately for the EU family card (tarjeta de familiar de comunitario), which follows a related but distinct process. See our full breakdown of that route and the wider Family Reunification Visa Spain page for how family cases are structured.

Income and insurance rules for non-workers

If you are registering as an EU citizen who is not employed, not self-employed, and not a student, the requirement shifts from proof of activity to proof of sufficient means: you must show you will not become an unreasonable burden on Spain’s social assistance system, plus valid health insurance covering your stay.

Unlike the non-lucrative visa for non-EU nationals, there is no single, uniformly published income figure applied nationwide for this EU registration route. Caseworkers commonly reference the IPREM income indicator as a benchmark, but the exact standard applied can vary by province and even by office within a province. This is one of the more common places clients get inconsistent informal advice, since a figure that satisfied an office in one region does not guarantee the same result elsewhere. We confirm the current practical standard used locally in Malaga before you file, rather than relying on a single generic number.

The green paper vs the TIE card confusion

This is the single most common point of confusion we hear from EU citizens settling in Spain. The TIE, Tarjeta de Identidad de Extranjero, is a plastic photo ID card issued to non-EU nationals holding a residency authorisation; it expires and requires fingerprinting. EU, EEA, and Swiss citizens registering under the community regime do not get a TIE at all. They get the green certificate instead, a paper document with no photo and no expiry date.

	Green Certificate (EU citizens)	TIE Card (non-EU)
Format	Green A4 paper	Plastic photo ID card
Expires?	Never	Yes, per permit validity
Who gets it	EU, EEA, Swiss citizens	Non-EU residents (or Withdrawal Agreement UK nationals)
Fingerprinting?	No	Yes, in person

Both processes assign an NIE number, which is exactly why the two get mixed up. See our NIE Number Spain guide and TIE Card Spain guide for the fuller picture of how the NIE, the green certificate, and the TIE card relate to one another.

The Brexit-era UK nationals note

This is a genuine exception worth stating clearly. UK nationals who were already living in Spain before the end of the Brexit transition period, 31 December 2020, are protected under the UK-EU Withdrawal Agreement. Despite retaining rights closer to an EU citizen’s than a typical third-country national’s, they hold a TIE card, not a green certificate, specifically marked to reference the Withdrawal Agreement.

UK nationals arriving in Spain now, after that cutoff, are third-country nationals under ordinary Spanish immigration law. They do not use this EU citizen registration process at all; they need a visa (non-lucrative, digital nomad, work, or another route) and then a standard TIE card, exactly like applicants from the US, Canada, or Australia. See our Non-Lucrative Visa Spain and TIE Card Spain guides for that route, and get in touch if you are unsure which category applies to your specific arrival date and situation.
