NIE Foreigner’s Guide — Step-by-Step Guide 2026
The NIE number is the first administrative milestone for any foreigner planning to buy property, open a bank account, or move to Spain in any way. Without it, nothing moves forward—and every year we see transactions being delayed at the very last minute simply because the NIE application was started too late.
The good news is that the process itself is manageable once you know which route fits your situation and what documentation you need to bring.
At Sunny Home Deals, we’ve guided hundreds of international buyers through the NIE process. In this article, we’ve gathered everything we know about it.
What is the NIE number?
NIE stands for Foreigner Identification Number: the identification number for foreign nationals. It’s a personal nine-character code (one letter, seven digits, and one letter) used by the Spanish authorities to identify you in any fiscal and legal context.
Think of it as, for foreigners, the equivalent of the identification number on a Spanish national ID document. It’s personal, for life, and the same number is used for every transaction you make in Spain.
When do you need an NIE?
You need an NIE for practically anything that has tax implications in Spain:
Buying a property or plot of land.
Opening a Spanish bank account.
Signing a mortgage.
Taking out utilities, internet, or insurance.
Selling or inheriting a property.
Registering a company or starting a business.
Buying or registering a vehicle.
If you’re only going on holiday, you don’t need it. But the moment you decide to buy something with tax weight or to settle in Spain, this is your first step.
The three ways to apply
There are three ways to get an NIE. Which one suits you best depends on where you are and how quickly you need it.
Route 1: Spanish consulate in your country of residence
We recommend this route if you have time to plan ahead. You book an appointment at the consulate or Spanish embassy in your country, submit the documentation in person, and you receive your number in 1–3 weeks.
Advantages:
You don’t need to travel to Spain.
You arrive with everything ready before the housing search even begins.
The consulate handles the process from your country of origin.
Disadvantages:
You need to live near a consulate or travel there.
During the busy season (March to July), appointments can be hard to secure.
Route 2: Police station / Foreign Nationals Office in Spain
If you’re already in Spain (visiting or staying longer), you can apply directly at a Foreign Nationals Office or at a police station with a counter for foreign nationals. You book the appointment online using prior appointment, and you submit your documentation on the day of the appointment.
Advantages:
Fast: often issued the same day or within a few days.
Helpful if you’re already planning a visit to Spain.
Disadvantages:
Appointments in high-demand locations (Alicante, Málaga, Marbella) get filled quickly.
Communication is entirely in Spanish; you may need a translator or a lawyer with you.
Route 3: Notarial power of attorney to a lawyer in Spain
We recommend this route when time is limited or when the buying process is already underway. You grant a Spanish lawyer a notarial power of attorney (poder notarial), which allows them to apply for the NIE on your behalf.
Advantages:
The quickest: usually completed in just a few working days.
You don’t need to travel or request an appointment at the consulate.
The lawyer can take care of the rest of the purchase at the same time.
Disadvantages:
Costs more (the lawyer’s fees, plus extra).
The power of attorney must include an apostille if it’s signed in your country of origin.
Documents you need
No matter which route you choose, you’ll need roughly the same documentation:
Passport (valid, not expired) and, in addition, a certified copy of the photo page.
EX-15 application form, filled out correctly and signed.
Justification of why you’re applying for the NIE (purchase contract, letter from the intermediary, a statement from the seller or from the lawyer: anything that shows a specific reason).
Proof of payment of the government fee (form modelo 790 código 012, around €10–€12 depending on the year).
Two passport-size photos (sometimes they’re required and sometimes not; it’s safer to bring them).
For the power of attorney route, your lawyer will also need the apostilled power of attorney and a certified copy of the passport.
Timelines and costs
Consulate abroad Time: 1–3 weeks Cost: ~€12 (government fee).
Police station in Spain Time: Same day–1 week Cost: ~€12 (government fee).
Power of attorney to the lawyer Time: 3–10 working days Cost: €200–€400 (lawyer’s fees + power of attorney included).
Remember: the NIE is for life. You only pay for it and complete the process once.
Common mistakes
Waiting too long. Many buyers start their NIE application once the purchase agreement has already been signed. That delays the closing by weeks. Start as soon as you begin thinking about buying.
Not justifying the application enough. Both consulates and police stations require a specific reason. “I might buy something” isn’t enough. Bring a letter from a real estate agency or a lawyer.
Forgetting the apostille on the power of attorney. If you sign a power of attorney in your home country, a notary public and your ministry of foreign affairs must attach the apostille—otherwise it won’t be accepted in Spain.
Confusing the NIE with residency. The NIE is only a tax number. It doesn’t grant you the right to live in Spain permanently. For that, you need a residence permit (a separate process).
When you already have your NIE
When your NIE is issued, you’ll receive an A4 sheet with the number. Keep the original in a safe place and scan a copy. You’ll need to present it or hand it over for every legal procedure in Spain—from opening a bank account to signing the title deed.
The number itself doesn’t expire and normally doesn’t require renewal. However, the A4 sheet may need to be reissued (updated with a new date stamp) for certain procedures if more than three months have passed since it was issued; even then, the number will remain the same.

Frequently asked questions
How long does it take to get an NIE? It can take anywhere from a few days up to three weeks, depending on the route. The fastest is through a lawyer with power of attorney (3–10 working days), and the slowest is via a Spanish consulate abroad (1–3 weeks).
Does an NIE cost money? The government fee alone is around €12. If you apply through a lawyer with power of attorney, expect an additional cost of €200–€400 for their service.
Do I need to speak Spanish to apply? No, if you apply through your home country’s consulate or via power of attorney to a lawyer. At a police station in Spain, all communication is in Spanish; therefore, you’ll need someone who speaks Spanish with you.
Does the NIE expire? No—the number itself is for life. The A4 sheet you receive may need to be reissued for certain procedures if it’s been more than three months, but the number stays the same.
Can I apply for an NIE for my partner at the same time? Yes, but each person needs their own application, their own documentation, and their own fee. That said, you can have the appointment together at the consulate.
Do my children also need an NIE if we buy the property together? Only if they’re listed as owners in the deed. If you and your partner buy in your own names, the underage children don’t need one.
