NIE Number Spain: What It Is, Why You Need One and How to Get One

If you’re searching for your dream home in Spain, there’s one small piece of paperwork you’ll require: the NIE number. Short for Número de Identidad de Extranjero, it’s a unique tax and ID number issued by the Spanish authorities to any foreign national who has financial, legal or professional dealings in the country. If you’re buying a home on the Costa del Sol, you can’t complete the purchase without one.

The good news is that getting an NIE is one of the more straightforward parts of the buying process in Spain. However, the application route, processing times and documents you’ll need can vary depending on where you apply. This guide walks UK buyers through everything you need to know: what an NIE actually is, why you need one, how to apply, what it costs and how long it takes.

What is an NIE number?

An NIE is a personal identification number that the Spanish Ministry of the Interior (Ministerio del Interior) issues to non-Spanish nationals. It’s a unique reference across the Spanish tax and administrative system, staying with you for life, even if you leave the country and come back years later.

An NIE number follows a simple format: a letter (usually X or Y), followed by seven digits, followed by another letter. For example: X-1234567-A.

Why do UK buyers need an NIE to purchase property in Spain?

As per GOV.UK, every foreign buyer purchasing real estate in Spain is legally required to have an NIE before completing the transaction. The number is needed to:

• Pay property transfer tax (ITP) on resale homes, or VAT (IVA) on new builds
• Sign the public deed of sale (escritura) at the notary
• Register the property in your name at the Land Registry
• Pay ongoing taxes such as IBI (council tax equivalent) and non-resident income tax

Since Brexit, nothing has changed about the NIE requirement itself for UK citizens. What has changed is the timing pressure around the 90/180-day rule, which limits how long you can stay in Spain as a visitor. If you’re planning to handle the NIE application in person in Spain, you’ll want to factor that into your travel plans, or use the UK route instead.

As part of the buying process that we help all our clients through, the NIE is one of the first steps we flag, because delays can hold up completion of the property purchase – and nobody wants that.

What else can you use your NIE for in Spain?

Once you have your NIE, you’ll use it for more than just your property purchase. It’ll likely show up on pretty much any form you have to fill in. It’s the single number that unlocks most of the administrative life of a foreign national in Spain, including:

• Opening a Spanish bank account
• Setting up utilities, such as electricity, water, internet and phone
• Paying property and non-resident income tax
• Buying a car or obtaining Spanish car insurance
• Signing employment contracts
• Applying for Spanish residency
• Importing belongings or registering at your local town hall

How to get an NIE number from the UK

For most UK-based buyers, applying through the Spanish Consulate at home is the most practical route, especially if you won’t be in Spain for a long enough period of time to apply there.

There are three Spanish Consulates that handle NIE applications for UK residents: London, Manchester and Edinburgh.

You’ll need to book an appointment through their online system, as availability can be limited.

The documents you’ll need:

• Original passport and a photocopy
• A completed EX-15 application form
• A completed Modelo 790, Código 012 tax form, plus proof you’ve paid the fee at a Spanish bank
• Justification of why you need an NIE, like a signed reservation contract or a letter from your Spanish lawyer confirming you’re attempting to buy property
• Two recent passport-sized photographs

How to get an NIE number in Spain

If you’re going to be in Spain long enough to apply for your NIE, there are plenty of avenues for you to pursue, such as at a police station or using your lawyer with power of attorney.

You can attend a designated Oficina de Extranjeros (Foreigners’ Office) or police station authorised to handle NIE applications. In most cases, that means booking a prior appointment online through the Spanish government portal. Documents are broadly the same as for the UK route: passport and photocopy, EX-15 form, Modelo 790 proof of payment and justification of your reason for applying.

You can also use a lawyer, which is often a route many of our clients choose, especially if they’re not expected to stay in Spain long enough to complete the process.

By signing a power of attorney, you can authorise your Spanish lawyer to apply for the NIE on your behalf. It’s much faster and removes the appointment headache, which means you don’t have to be present. The trade-off here is cost, though – you’ll have to pay the lawyer a fee on top of the government charge, but it’s money well spent.

How long does it take to get an NIE number in Spain?

It depends on whether you apply in Spain or via the UK, and if everything is in order. Occasionally, you can walk out on the same day with an NIE certificate in Spain, but it can take from a couple of days to a fortnight to arrange normally.

If you’re applying in the UK via a Consulate, it can take longer (around 3 to 6 weeks). If you’re using a lawyer with power of attorney, processing is generally quick once the paperwork is lodged, potentially taking up to three weeks for completion.

How much does an NIE number cost?

The official government fee is not too steep, roughly sitting at €9.84. This is payable via the Modelo 790 Código 012 form through a Spanish bank. This is the same whether you apply in Spain or through a UK Consulate.

If you use a lawyer to apply on your behalf, you can expect to pay a service fee of around €100 to €250 on top of the government charge, depending on the provider you use.

Does an NIE expire?

No, an NIE number is permanent. Once it’s issued, it’s yours for life. Even if you lose the certificate, the number remains valid.

The physical certificate, on the other hand, carries an issue date. Some Spanish institutions will ask for a certificate issued within the last three months when opening accounts or completing certain transactions.

If your NIE certificate is older than that and you need to use it for a new institution, you may be asked to request a fresh copy.

The number doesn’t change; only the dated document.

Starting your Spanish property journey

The NIE is one step in what is typically a simple process, and not the bureaucratic nightmare it’s made out to be.

Between the reservation contract, due diligence, private purchase contract and completion, there’s a lot to stay on top of with a Spanish property purchase. So, it pays to have people around you who have done it multiple times before.
