The NIE (Número de Identificación de Extranjero) is the single most important document in any Spanish property transaction. Without it, you cannot sign a purchase deed, open a Spanish bank account, pay taxes, or register a property in your name. Yet many foreign buyers arrive in Spain — or sign a reservation contract — without one, causing costly delays. This guide explains exactly what an NIE is, how to get one in 2026, and what to do if you cannot be present in Spain to apply.

What Is an NIE and Why Do You Need It?

An NIE is a unique tax identification number issued to foreign nationals in Spain. The full name is Número de Identificación de Extranjero. It is a permanent number — once issued, it does not expire and you will use it for every official transaction in Spain for the rest of your life.

For property buyers, the NIE is mandatory. It must appear on the purchase deed (escritura de compraventa), on all tax payment forms, on your Spanish bank account, and on utility contracts. Spanish law does not permit property transactions to proceed without a valid NIE for the buyer.

NIE Application: Step by Step

Step 1: Book an appointment. NIE appointments for property buyers in the Alicante / Torrevieja area are booked online at sede.policia.gob.es. Go to ‘Trámites’, then ‘NIE y certificados’, then select ‘Asignación de NIE’. Availability varies — book as early as possible, ideally before you even start viewing properties.

Step 2: Complete form EX-15 (for EU citizens) or EX-17 (for non-EU citizens). These forms are available on the Spanish Interior Ministry website. Complete them in Spanish. If you need help, we can assist.

Step 3: Prepare your documents. You will need: your valid passport (original and photocopy), a completed EX-15 or EX-17 form, proof of the reason for your NIE application (e.g., a signed reservation contract or a letter from your property advisor stating your intention to purchase), and the application fee (Tasa 790, Code 012) paid in advance at any Spanish bank branch.

Step 4: Attend your appointment at the designated Foreigners’ Office or National Police Station. In Torrevieja, this is handled at Comisaría de Policía Nacional. In Alicante, at the Oficina de Extranjería on Calle Decoración.

Step 5: Collect your NIE. For EU citizens, the NIE is often issued the same day. For non-EU citizens, processing typically takes 2–4 weeks. You will receive a green certificate (certificado de asignación de NIE) — this is your NIE document.

NIE Processing Times in 2026

EU citizens (including EEA nationals) typically receive their NIE on the same day as their appointment, or within a few days. Non-EU citizens — including British nationals post-Brexit, Russians, Ukrainians, Americans, and others — should expect 2–4 weeks from the appointment date.

Appointment availability in the Torrevieja and Alicante area varies significantly by season. In summer, waiting times for an appointment can reach 3–5 weeks. In winter, appointments are often available within 1–2 weeks. This is why we strongly recommend starting the NIE process before you begin property viewings — not after you have found a property.

Can Someone Apply for My NIE on My Behalf?

Yes. If you cannot travel to Spain, or if you want to save time, you can grant a power of attorney (escritura de apoderamiento) to a trusted representative who can apply for your NIE on your behalf. The power of attorney must be notarised and — if signed outside Spain — apostilled.

Sarah Katerina regularly applies for NIE numbers on behalf of clients who are purchasing remotely. We handle the appointment booking, the form completion, the Tasa 790 payment, and the collection of the NIE certificate — without you needing to be in Spain.

Common NIE Mistakes to Avoid

The most common mistake is waiting until after signing a reservation contract to start the NIE process. At that point, you are committed — and if your NIE is delayed, your purchase timeline slips.

The second most common mistake is completing form EX-15 or EX-17 incorrectly. Even small errors — a wrong date format, a missing address — can cause the application to be rejected. Always have the forms checked before your appointment.

Non-EU citizens sometimes underestimate processing times. A 4-week delay on an NIE can mean missing a contractual deadline, which in the worst case means losing your 10% deposit. Start early.

Frequently Asked Questions

What does NIE stand for in Spain?

NIE stands for Número de Identificación de Extranjero — Foreigner Identification Number. It is a unique tax and identification number issued to foreign nationals and required for all official transactions in Spain, including property purchases.

How much does it cost to get an NIE in Spain?

The NIE application itself costs €10.71 (Tasa 790, Code 012) paid at a Spanish bank branch. If you appoint a representative, there will be notary fees for the power of attorney (approximately €60–150) plus any professional fees for handling the process.

Do I need a new NIE every time I buy a property in Spain?

No. Your NIE is a permanent, lifelong number. Once issued, you use the same NIE for every property transaction, tax filing, and official process in Spain.

Can I use my NIE certificate to open a Spanish bank account?

Yes. Your NIE certificate, combined with your passport, is the standard documentation required to open a non-resident bank account at Spanish banks such as CaixaBank, Sabadell, or BBVA.

What is form EX-15 and EX-17?

EX-15 is the NIE application form for EU/EEA citizens. EX-17 is the equivalent form for non-EU citizens. Both are available from the Spanish Interior Ministry website and must be completed in Spanish.
