You've been in Madrid for a few weeks. Things are going well. And then your landlord, or your new boss, or the clerk at the bank says the same words every EU citizen here eventually hears: "Necesito tu NIE verde."

If you're an EU, EEA, or Swiss citizen planning to stay in Spain for more than three months, the NIE verde is the document that turns you from "visitor" into "resident on paper." Here's exactly what it is, what to bring, and where to go in Madrid.

Quick honesty: I'm not an EU citizen myself, so my own route into Spain was the TIE, not the NIE verde. But I've sat in the same comisaría queues helping EU friends and clients get theirs, and the rhythm of it (the form, the tasa, the appointment that vanishes) is identical. So this is the version I wish someone had handed them.

What Is the NIE Verde (and Why Does Everyone Keep Asking for It)?

The NIE verde is officially the Certificado de Registro de Ciudadano de la Unión Europea, or CUE. It's a green paper certificate (hence "verde") issued to EU, EEA, and Swiss citizens who'll live in Spain longer than three months. It contains your NIE number, your permanent ID number in Spain, the one that follows you onto every contract, payslip, and trámite from here on.

It's paper, not a card, and yes, it's a little anticlimactic for something so important. Laminate it. People ask for it constantly.

NIE Verde vs. NIE Blanco: What's the Difference?

This trips everyone up, so here's the plain version. The NIE blanco just assigns you a NIE number, handy for one-off things like buying property or a quick tax matter. The NIE verde goes further: it registers you as a resident. Same number underneath, different document, different purpose. If you're moving here to live, the verde is the one you want.

What Documents Do I Need for the NIE Verde?

Bring everything, and bring a photocopy of everything. This is the list that actually gets you through in one visit:

• Completed form EX-18 (not EX-17, this is the single most common mistake, more below).
• Valid passport or national ID, original and a photocopy.
• One passport-size photo, white background.
• Tasa 790 Código 012 payment receipt (around €10.71), paid before your appointment, not on the day.
• Proof of why you're staying: an employment contract, or if you're not working, bank statements showing you can support yourself plus private health insurance.

Where Do I Apply for the NIE Verde in Madrid?

You go to a Comisaría de Policía with an extranjería office, by appointment (cita previa) only. Common Madrid ones:

• Comisaría de Los Leones, Calle Los Leones de Castilla, 12.
• Comisaría de Moratalaz, Avenida de Moratalaz, 52.
• Comisaría de Fuencarral, Calle Estébanez Calderón, 1.

The appointment itself is usually quick. Finding the appointment is the hard part, the cita previa slots open and disappear in minutes, which is what quietly costs people weeks.

Common Mistakes to Avoid

• Filling in EX-17 instead of EX-18. Different form, different procedure. Double-check.
• Trying to pay the Tasa 790 on the day. It has to be paid beforehand, receipt in hand.
• Forgetting the photocopies. There's rarely a copy machine waiting for you, and "I'll be right back" is how appointments get lost.

Quick Questions People Ask

Is the NIE verde the same as the TIE? No. The NIE verde (CUE) is for EU citizens. The TIE is the physical card for non-EU residents. Different documents, different people.

Does the green certificate expire? The NIE number is permanent. After five years of legal residence you can apply for the permanent version of the certificate.

Do I need to be empadronado first? Often yes, and it makes everything easier. (Here's our empadronamiento guide.)

I lost my green paper. Now what? You keep the NIE number forever, but you'll want a duplicate certificate, which is another appointment, sadly.

The Real Question

Getting the NIE verde isn't complicated. Getting an appointment before your landlord loses patience, paying the right tasa with the right code, and bringing the right form (EX-18, I promise it matters), that's where the time goes.
