What Is a NIE Number?

NIE stands for Número de Identidad de Extranjero — your Spanish foreigner identification number. It's a personal, unique, permanent tax ID assigned to any foreigner who needs to do anything official in Spain.

Think of it as your Spanish social security number. You'll need it for:

• Buying property
• Opening a bank account
• Getting utilities (electricity, water, internet)
• Getting a mortgage
• Paying taxes
• Starting a business
• Registering with a doctor
• Enrolling children in school

It's permanent — once you have it, you keep it for life, even if you never live in Spain.

Do You Need a NIE to Buy Property?

Yes. You cannot buy property in Spain without a NIE number. The notary will not let you sign the deed without it.

You also need it before you can open the Spanish bank account that you'll use to pay the deposit.

How to Apply for Your NIE

There are two main routes, depending on where you are:

Option 1: In Spain (Faster)

Apply at a National Police station (Comisaría de Policía) with an Extranjería office.

1. Book an appointment (cita previa) online at the National Police website
2. Complete form EX-15 (Solicitud de NIE)
3. Pay the fee (tasa) at a bank — currently ~€9.86
4. Attend your appointment with your documents
5. Receive your NIE — often the same day, sometimes within a week

Option 2: At a Spanish Consulate (From Abroad)

Apply at the Spanish consulate in your home country.

1. Contact your local consulate to check their process
2. Complete form EX-15
3. Pay the fee — varies by consulate (~€9–€15)
4. Submit by post or in person
5. Wait — processing time is 1–4 weeks

Option 3: Use a Lawyer or Gestor

If you're not in Spain and don't want to deal with the consulate, a Spanish lawyer or gestor can apply on your behalf with a power of attorney.

• Cost: €50–€150 (plus the government fee)
• Time: 2–4 weeks
• Convenience: High — they handle everything

Documents You'll Need

• Completed EX-15 form (available online)
• Valid passport + a photocopy
• Passport-size photograph (sometimes required)
• Proof of reason for NIE — e.g. a property reservation contract, a letter from a lawyer, or a job offer
• Fee payment receipt (the tasa, paid at a bank before your appointment)

If applying by proxy (through a lawyer), you'll also need a notarised power of attorney.

How Long Does It Take?

If you're buying property soon, start your NIE application immediately — it's the most common delay in the buying process.

How Much Does It Cost?

• Government fee (tasa): ~€9.86
• Consulate fee (abroad): ~€9–€15 (varies)
• Lawyer/gestor service: €50–€150 (if using one)

It's one of the cheapest parts of the whole buying process.

Common Questions

Is the NIE the same as residency?

No. The NIE is just an ID number. Residency (residencia) is a separate process that gives you the right to live in Spain. You can have a NIE without being a resident.

Does the NIE expire?

No. Once issued, your NIE is permanent and never expires.

Can I get a NIE before finding a property?

Yes — and you should. Having your NIE ready speeds up the buying process significantly.

Do I need to be in Spain to get a NIE?

No. You can apply at a Spanish consulate in your home country, or use a lawyer with power of attorney.

Next Steps in the Buying Process

1. Open a Spanish bank account (passport + NIE)

Your NIE is the key that unlocks everything else. Get it sorted early, and the rest of the process flows smoothly.
