NIE number to buy property in Spain: what it is and how to get it

The NIE is the first piece of paperwork any foreign buyer needs in Spain. Without it you cannot sign the purchase deed, open a bank account or apply for a mortgage. This guide covers what it is, where to apply and how to delegate it if you cannot handle it in person.

What the NIE actually is

The NIE (Número de Identidad de Extranjero) is a personal, non transferable number that identifies a foreign national to the Spanish administration. It is not a residence permit and it grants no immigration status. It works purely as a tax and administrative identifier.

The version most of our clients need is the one applied for on economic grounds: buying a property, opening a bank account, signing utility contracts. You do not need to live in Spain to hold one.

Where to apply: police station in Spain or consulate at home

Both routes are valid.

A national police station in Spain, at the immigration office covering the province where you plan to buy. You need an appointment booked online, and it pays to book weeks ahead. If you are buying in Altea, the relevant office is in Alicante.

The Spanish consulate in your country of residence, before you travel. This suits buyers who would rather not spend part of a short trip to Spain queueing at an administrative counter.

Documents you need

• A valid passport, original plus a photocopy.
• Form EX15, the official NIE application.
• Evidence of why you need it. For a purchase, a reservation contract or deposit agreement is normally enough.
• Proof that the fee has been paid.

Each consulate and each police station adds its own details. Confirm the exact list before your appointment, because a single missing document means booking again and losing weeks.

Which route suits you

Applying in Spain has the advantage of resolving it while you are already viewing properties or closing the deal. The drawback is appointment availability: in high demand provinces like Alicante, slots go quickly.

Applying at your consulate avoids that scheduling problem but adds travel to the consulate, which may not be in your city, and the diplomatic route can take a little longer. If your nearest consulate is far away, weigh up whether an earlier trip to Spain makes more sense.

Can a lawyer do it for you?

Yes, and for buyers who are not yet in Spain this is the usual route. A power of attorney signed before a notary in your own country, then legalised for use in Spain, lets a lawyer or gestor apply for the NIE on your behalf.

The same power of attorney can then be used to sign the deposit contract and the deed itself, which matters if your work will not let you fly out twice. Make the scope explicit: applying for the NIE only, or also signing contracts, opening bank accounts and executing the purchase deed. A broader power means fewer documents to sign remotely, and also more trust placed in one person.

Does it expire?

The number itself does not. It stays yours for life and you will keep using it to file taxes, sell the property later or sign contracts in Spain. A physical card, where one is issued, can expire, but a purchase only requires the NIE certificate, which carries no expiry date.

If you lose the certificate, a duplicate can be requested at the same police station that issued it, or through your lawyer under power of attorney. You do not repeat the whole application.

Mistakes we see most often

Applying too late. In peak season, immigration appointments in Alicante are gone weeks in advance. Start when you decide to buy, not when you already have an accepted offer and a completion date.

Turning up with incomplete paperwork. One missing form means a new appointment.

Getting the order wrong with the bank. Some Spanish banks want the NIE issued before they open an account, so doing it the other way round adds delay for no reason.

Assuming the NIE lets you live in Spain. It does not. It is a tax and administrative identifier. If your plan involves spending more than 183 days a year here, that is a separate matter worth discussing with an adviser, because it changes your tax residence.

Realistic timing, as at August 2026

Two to four weeks from the appointment is normal, though the figure moves with the workload of the office and the time of year. Treat it as a guide, not a guarantee.

If your purchase has a deadline, start the NIE as soon as you decide to look for a property in the Altea area. It is the step that most often holds up everything else.

What it costs

The fee itself is modest, a matter of tens of euros paid through the standard tax form before your appointment. What actually costs money is delegating: a lawyer or gestor handling the application typically charges a few hundred euros, and the notarised and legalised power of attorney adds its own cost in your own country.

For most buyers that is money well spent, because the alternative is a flight and a day lost to a queue. But it is worth asking for the fee quoted in writing before instructing anyone, and asking whether it covers only the NIE or the wider purchase representation.

One NIE per buyer

If you are buying jointly, every person who will appear on the deed needs their own NIE. Couples routinely discover this late and lose weeks because only one of them applied.

The same applies if you are buying through a company: the company needs its own tax identification number, and the individual signing on its behalf still needs a personal NIE.

Once you have it

The next step is a Spanish bank account, which you need to pay the reservation, the deposit and the costs around the purchase. After that you can move on to checking the land registry filing and any charges (in Spanish) on the property you like, and if you are financing, start the mortgage application for non residents.

The NIE keeps working long after completion: registering a car, taking out private health cover, putting the electricity contract in your own name rather than leaving it with the previous owner. Treat it like your passport, not like a form you throw away after the notary.

This is general guidance on the procedure, not legal advice. Confirm the requirements for your own case with a lawyer or gestor before booking an appointment.
