An NIE number in Spain is a tax identification number for foreign nationals. You need it to buy property, open a Spanish bank account and pay taxes. You can apply in person at a police station in Spain, through a Spanish consulate abroad, or via a lawyer with Power of Attorney. Most applications are processed within two weeks.
Before you can buy a home in Spain, there’s one key document you’ll need: an NIE – your official tax ID for property, banking and legal matters. Without it, you won’t be able to complete a purchase, open a bank account or sign most contracts.
Whether you’re planning a viewing trip or preparing to reserve a property, applying for your NIE should be high on your to-do list. This guide explains how to apply, what documents you’ll need and when to get it sorted in your buying journey.
What is an NIE number in Spain?
An NIE (número de identidad de extranjero) is the tax identification number issued to foreign nationals in Spain. You need one to buy property, open a bank account, pay taxes or sign most official contracts. It applies to all non-Spanish nationals, regardless of nationality or residency status. One caveat: the NIE identifies you for tax purposes only – it does not grant the right to live in Spain.

- You can apply in Spain, through a Spanish consulate abroad or via a lawyer with Power of Attorney
- Processing times range from the same day to two weeks, depending on the region

How to get an NIE number in Spain
Applying for an NIE in person while you’re in Spain is relatively straightforward.
You’ll need to make an appointment at a designated police station or immigration office (Oficina de Extranjeros). It’s strongly advised to pre-book this online via sede.administracionespublicas.gob.es, which has an English version. Without a booking, you may face long queues or be turned away.
It’s also worth noting that English isn’t spoken in all Spanish police stations – especially in remote areas. It will be a huge help if you can speak Spanish, or you take someone with you who does.
You will need to complete an EX-15 form, which is in Spanish. Many buyers choose to have a lawyer or estate agent help them complete the paperwork accurately.
| Route | Who it suits | Where to apply | Typical timeline |
|---|---|---|---|
| In person in Spain | Buyers already in the country or on a viewing trip | Local police station or Oficina de Extranjeros | Same day to two weeks |
| Spanish consulate abroad | Buyers not yet travelling to Spain | Spanish Embassy or Consulate in home country | Two to four weeks |
| Via a lawyer (Power of Attorney) | Buyers who prefer not to apply in person | Your Spanish lawyer applies on your behalf | Two to four weeks |

How to get an NIE number from your home country
If you’re applying from outside Spain, your local Spanish Embassy or Consulate can handle your application. This must be done in person – there is no online-only option.
However, it doesn’t have to be you who applies. You can authorise a Spanish-based representative (usually your lawyer) to apply on your behalf using a Power of Attorney. The representative will need a certified copy of your passport along with the required documents.
What documents do you need to apply?
To apply for an NIE, you will need:
- EX-15 form – downloadable from the Spanish government website or available at the police station. It must be completed in Spanish.
- Original passport plus two photocopies – bring both the photo page and any relevant visa pages.
- Two recent passport-sized colour photographs
- Proof of address – a utility bill, bank statement or tenancy agreement from your home country.
- Proof of reason for application – for property buyers, a signed reservation contract is the standard document accepted.
- Power of Attorney document – required only if a lawyer or representative is applying on your behalf.
If applying through a Spanish consulate, check requirements directly with your local consulate before attending, as they can vary slightly by country.
Processing times vary. In some regions, you’ll be given your number immediately after the appointment. In others, expect to wait between two days and two weeks.
Why do I need an NIE number?
The NIE is how the Spanish authorities identify you for tax purposes. Without one, you won’t be able to complete any official or financial process related to your property purchase. You’ll need it to:
- Buy or sell a property
- Pay taxes
- Open a bank account
- Apply for a residence permit
- Buy a vehicle or take out a phone contract
- Organise utilities and insurance
Your NIE will also appear on your Spanish residence card if you later choose to live in Spain permanently.
The number itself is nine characters long and starts with a letter (X for foreigners), followed by seven digits, and ending with another letter.
When should you apply for your NIE?
The right time to apply depends on where you are in your buying journey.
On a viewing trip: If you’re likely to reserve a property while in Spain, apply during the trip. Many buyers do this on their first or second day, before viewings begin, to avoid delays later.
Before reserving a property: Some agents and developers will ask for your NIE at the point of reservation. Applying before you travel means it’s ready when you need it.
After reserving, before exchange: At the latest, you’ll need your NIE in place before signing the contrato de arras (reservation contract) or the full purchase deed. Waiting until this stage adds unnecessary pressure.
Your estate agent or lawyer can usually help you book an appointment and, in many cases, accompany you to the correct police station. Getting it sorted early avoids one of the most common causes of delay in the Spanish buying process.
