How to get the NIE in Spain as an EU / Erasmus student (2026 guide)

The NIE for EU students is the document Spain politely insists you need but treats like an inconvenience. The system pretends you're EU and therefore free to move — and simultaneously requires you to register, pay a fee and queue for an appointment that doesn't exist.

This is the 2026 step-by-step. The forms, the bank payment, the appointment system that breaks every Monday at 8 AM, and the documents that get half of students sent home and told to come back tomorrow.

What "the NIE" actually is when you're an EU citizen

The terminology trips up everyone, so let's clarify:

• NIE (Número de Identidad de Extranjero) — a number. Looks like X-12345678-A or Y-12345678-B. You'll use it on contracts, taxes, healthcare, the lot.
• Certificado de Registro de Ciudadano de la Unión — a green A4 paper certificate that confirms you're registered on the Central Foreigners' Registry as an EU citizen residing in Spain.
• Green NIE — slang for the certificate above. People say "I got my NIE" when they mean "I got my certificado".

For EU students you do the registration once, pay one fee, and walk out with both the number and the certificate. Non-EU students go through a different (longer) process to get a physical card called the TIE — see our TIE guide for non-EU students for that.

Who needs to do it

The official rule: any EU/EEA/Swiss citizen staying in Spain for more than 3 months is legally required to register and obtain the certificate.

In practice:

• Erasmus students staying a full semester (4–10 months) — yes, do it
• Exchange students staying less than 3 months — technically no, but it's still useful for opening a real Spanish bank account, signing a long phone contract or getting a transport pass that requires proof of residency
• Anyone planning to work part-time in Spain — yes, your employer will ask for the NIE in the first contract
• Anyone applying for a Spanish grant — yes, the IBAN must match a name with a Spanish ID number

If you're staying 3 months or less and you only need a basic prepaid SIM and Revolut, you can skip the NIE. For anything more permanent, do it.

Before you book — what to prepare

You need three things, and the order matters:

1. A confirmed address in Spain with proof (your rental contract or, more often, your volante de empadronamiento — see our empadronamiento guide)
2. The EX-18 form — downloadable from the official police website. Fill it in in Spanish, in blue or black pen, no Tipp-Ex. Sign it.
3. The modelo 790 código 012 — the tax form for the fee. Generate it from the Ministry of Interior site, print three copies, take to any bank in Spain that accepts public taxes (BBVA, CaixaBank, Santander, Sabadell, Bankinter all work).

Pay the €12.10 fee at the bank, get the stamped receipt back. Without that stamped receipt the police will not process you.

You will also need:

• Your passport (original — they don't accept photo IDs from other EU countries even though technically your national ID card should suffice; bring the passport to avoid the argument)
• Photocopy of the passport (data page only)
• Proof of residence in Spain (empadronamiento, ideally less than 3 months old)
• Proof of enrolment at your Spanish university (in Spanish — your International Office issues this)
• Proof of financial means — typically a bank statement showing you have enough to support yourself (~€600/month × duration of stay), OR a letter confirming you're receiving the Erasmus+ grant, OR a parental support letter with their bank statement
• Proof of health coverage — your EHIC card (European Health Insurance Card) is the standard answer, or a private insurance policy with full medical coverage in Spain
• All photocopies: passport, EHIC, empadronamiento, university enrolment, financial proof. The police often keep the photocopies and return originals.

The thing nobody mentions: bring two photocopies of everything. The form 790 receipt, the passport, the EHIC — they sometimes lose one and you save yourself a 30-minute walk to the fotocopiadora.

Booking the cita previa

The appointment is booked through the central platform: sede.administracionespublicas.gob.es → Citas → select your province → select "Certificados UE" or "Asignación NIE" depending on what your province lists.

The realistic experience:

• Refresh the page repeatedly. Slots open and disappear in seconds — especially in Madrid, Barcelona and Valencia.
• Try Tuesday–Thursday early mornings. Mondays are gridlocked because of the weekend backlog.
• Try every office in your province. Madrid has multiple comisarías handling NIE; Barcelona similarly. The Móstoles office processes Madrid residents and is often less saturated than the central one.
• Don't use third-party "appointment finder" sites that charge €30+. They use the same public endpoint you do — they just bombard it. You're paying for inconvenience, not access.

If you genuinely can't get an appointment within your needed timeframe:

• Gestorías charge €40–€80 to book on your behalf. Reasonable people use them; it's a real industry with no shame attached.
• Some cities have "ampliaciones" of slots at 9 AM on Monday or after 8 PM on Friday — set a phone alarm and try the system at those times.
• Document everything. Screenshots of empty appointment lists are valid evidence of impossibilidad if anyone questions why your registration is late.

The appointment day

Arrive 15 minutes early. Bring everything in a folder, in this order:

1. Passport on top
2. EX-18 (filled, signed)
3. 790-012 receipt (stamped by bank)
4. Empadronamiento volante
5. University enrolment proof
6. Financial proof
7. EHIC or insurance proof
8. All photocopies behind each original

At the desk, the police officer will:

1. Check your passport
2. Check the form 790 receipt — no receipt, no service
3. Review your other documents
4. Type your details into the system
5. Print the green certificate (certificado de registro) with your name, NIE number, address, date and an official stamp
6. Hand you the certificate and your originals back

The whole interaction takes 20–30 minutes. You walk out registered.

Don't lose the green certificate. It's a single A4 sheet of plain paper with a stamp. Photograph it, scan it, store it in your email and your cloud. Replacement is technically possible (you re-do the registration) but you'll wish you hadn't lost it.

After you have the NIE

Things you can now do that you couldn't before:

• Open a full Spanish bank account (BBVA, CaixaBank, Santander) — required for some Erasmus grant payments
• Sign a yearly rental contract in your own name
• Sign a phone contract with monthly billing instead of prepaid
• Register with the public health system (SNS) if your studies extend long enough that the EHIC stops covering you
• Get a Spanish driving licence issued in your name (rare for Erasmus, useful for longer stays)
• Pay Spanish taxes in your name if you start any paid work, internship or freelance gig

The number itself goes on every Spanish form for the rest of your life — if you come back as a tourist, as an employee, as a homeowner, the NIE you got as a student is the one that follows you.

Common pitfalls

• Filling the EX-18 in pencil or with corrections. It gets rejected. Print a fresh copy if you mess up.
• Paying the 790 at the wrong type of bank. It must be a bank that handles state taxes (Cajeros con servicio de pago de tasas). BBVA, CaixaBank, Santander, Sabadell, Bankinter all work. ING, Openbank and most digital-only banks don't process the 790. If your bank refuses, walk into any high-street bank — they're legally required to process the tax for non-customers.
• Bringing financial proof in your home currency only. Some officers accept it, some don't. Bring a Spanish bank statement if you have one, or a recent statement clearly translated/explained.
• Showing up with an EHIC that expires before your stay ends. Renew before you leave home — it takes 2 weeks in most EU countries and is free.
• Getting confused between the certificate and the TIE card. Some EU students arrive thinking they need a card with a photo (like the TIE). They don't. The green A4 paper is the final document.

The 24-hour fast path (when you absolutely need it)

If you have an internship starting Monday and you don't have the NIE:

1. Today: download EX-18, print 790-012, walk into BBVA branch, pay the €12.10
2. This afternoon: secure all photocopies and documents in one folder
3. This evening: refresh the cita previa page from 8 PM to midnight — slots for next-day appointments sometimes appear from cancellations
4. Tomorrow: if you got the slot, you walk out registered tomorrow morning. If not, bring everything to your local comisaría and ask for an atención urgente citing the work contract reason — sometimes accepted in smaller cities.

This is the emergency path. For most students the standard route — book 2–3 weeks ahead — works fine.

The NIE certificate is one of those Spanish bureaucratic milestones: painful to set up, then quietly useful for the next decade. Once you have the green paper, every other Spanish form gets easier.
