No NIE number, no house in Spain. It is the first official document you need, and at the same time the step where most buyers lose unnecessary time. This guide explains exactly what a NIE is, how to apply for one from the Netherlands or Belgium, what it costs and how long it takes. That way you know precisely what to arrange before you sit down at the notary.
What exactly is a NIE number?
NIE stands for Número de Identidad de Extranjero, the Spanish identification number for foreigners. Think of it as a Spanish social security number: a unique number linked personally to you that you keep for life. It is not a residence permit, and it does not automatically make you liable for tax in Spain. It is simply the number by which the Spanish authorities recognise you in anything involving money, property or tax.
When do you need a NIE?
You need a NIE as soon as you buy or arrange anything of value in Spain. In practice that comes down to:
- signing the deed of sale at the notary
- opening a Spanish bank account
- applying for a Spanish mortgage
- registering the property in the land registry
- connecting water, electricity and internet
- declaring and paying taxes such as the IBI
If you are buying together with your partner, each buyer needs their own NIE. If the property will be registered in two names, count on two applications.
The three ways to apply for a NIE
1. At the Spanish consulate in the Netherlands or Belgium
The most common route for buyers who are still at home. You book an appointment with the consulate online, submit form EX-15 together with your passport and evidence of your economic reason, and collect the document later. The advantage is that you do not have to travel to Spain. The drawback is the waiting time: in busy periods an appointment can take several weeks or even months, so start early.
2. In Spain at the Policía Nacional
If you happen to be in Spain, for example during a viewing trip, you can apply on the spot at a foreigners office (Oficina de Extranjería). You book a cita previa online in advance, pay the fee using modelo 790 (código 012) at a bank and submit everything in one go. In many cases you receive your number the same day or within a few days.
3. Through a power of attorney
The fastest and most relaxed route: you give a Spanish lawyer or gestor a power of attorney (poder notarial) and they submit the application on your behalf. You sign the power of attorney before a notary in the Netherlands or Belgium, have it legalised with an apostille and send it over. After that you do not have to do anything yourself. For buyers with a busy schedule this is almost always the best choice, certainly if you buy off-plan and several signing moments follow.
The application in six steps
- Choose your route: the consulate, in Spain itself or through a power of attorney.
- Gather your documents: a valid passport plus a copy, a completed EX-15 form and evidence of your economic reason, for example a reservation contract or a statement from your estate agent.
- Book an appointment, online at the consulate or via cita previa in Spain.
- Pay the fee using modelo 790 and keep the proof of payment.
- Submit everything and check your details carefully: a misspelled surname can easily cost you weeks.
- Collect your NIE or have it forwarded, and make a few certified copies straight away.
Costs and processing time
The fee itself is low: count on roughly 10 to 12 euros per person. If you hand the whole thing over to a lawyer or gestor, that usually costs 150 to 300 euros per application, including the power of attorney and the translations. Compared with the total buyer's costs of 8 to 13% on top of the purchase price, that is a negligible expense.
Processing time varies considerably by route. In Spain you are often done within a week; through the consulate you should count on four to eight weeks, and longer in high season. So start the application before you definitively reserve a property, not afterwards.
The most common mistakes
- Starting too late. The application itself is almost never the problem, the waiting time for an appointment is.
- Applying for only one NIE while you are buying together.
- Turning up with a passport that is about to expire.
- Being unable to show evidence of your economic reason, which gets the application rejected.
- Thinking your NIE expires. The number is valid for life; only the paper certificate sometimes has a limited validity.
Planning to rent the property out? Then, in addition to your NIE, you also need a holiday rental licence , which you only apply for once the property is in your name.
What comes after your NIE?
With your NIE in hand you can open a Spanish bank account, apply for a Spanish mortgage and sign at the notary.

Frequently asked questions
How long does applying for a NIE number take?
In Spain itself you are often done within a week; through the Spanish consulate in the Netherlands or Belgium you should count on four to eight weeks. The real delay is almost always the waiting time for an appointment, not the processing itself.
What does a NIE number cost?
The fee is roughly 10 to 12 euros per person. If you hand the application over entirely to a lawyer or gestor, you normally pay 150 to 300 euros per application, including the power of attorney and translations.
Do I have to travel to Spain for my NIE?
No. You can apply at the Spanish consulate in the Netherlands or Belgium, or give a power of attorney (poder notarial) to a Spanish lawyer who arranges everything on your behalf. You then only need to travel to Spain for the viewing or the notary.
Does my NIE number expire?
The number itself is valid for life and stays linked to you. Only the paper certificate can have a limited period of validity; you simply have it reissued without receiving a new number.
