How to apply for an NIE to buy property in Spain step by step

If we are thinking about buying a property in Spain and we are not Spanish, there is one essential step we must take into account: applying for an NIE. Without this number, we will not be able to formalise the property purchase or carry out other procedures related to the home.

The NIE is mandatory even if we do not plan to live in Spain. In other words, even if we only want to buy a property as a second home or an investment, we will need to obtain it beforehand.

At Fotocasa, we explain what the NIE is, when it must be requested and how to apply for it step by step if we are non-resident foreigners.

What is the NIE and why is it mandatory to buy property in Spain?

The Foreigner Identification Number (NIE – Número de Identidad de Extranjero) is a personal, unique and exclusive number assigned to foreigners who have a relationship with Spain for economic, professional or social reasons.

This number allows us to identify ourselves before the Spanish Administration.

In the case of buying a property, the NIE is required to:

• Sign the deed before a notary

• Pay taxes related to the purchase

• Register the property with the Land Registry (Registro de la Propiedad)

• Arrange utility contracts

It is important to clarify that the NIE is mandatory to buy a property even if we are not residents in Spain. It is not necessary to live in the country to obtain it, but it is essential for any transaction with economic significance, such as purchasing a property.

When should we apply for the NIE if we want to buy a property?

The NIE must be requested before formalising the purchase.

Since it is required to sign the deed and make the corresponding payments, it is advisable to start the process well in advance as part of the property purchase procedure.

If we wait until the last minute, the procedure may delay the transaction.

How to apply for an NIE step by step

The procedure can be carried out either in Spain or from abroad.

Where can you apply for an NIE?

There are two main options:

• In Spain, at Immigration Offices (Oficinas de Extranjería) or authorised Police Stations.

• Abroad, at the Spanish Consulate corresponding to the applicant’s place of residence.

What documents must be submitted?

According to official information, the following must be provided:

• The official application form (EX-15 form).

• A valid and complete passport (original and copy).

• Proof of the reason for requesting the NIE (for example, the intention to buy a property).

• Payment of the corresponding fee.

The application must be submitted in person or through a duly authorised representative.

Is an appointment required?

In Spain, the application usually requires a prior appointment (cita previa), which is arranged through the Police Electronic Headquarters (Sede Electrónica de la Policía).

If applying from abroad, the procedure is carried out through the corresponding Spanish Consulate, which may also require a prior appointment.

How much does it cost to apply for an NIE?

The assignment of an NIE is subject to payment of an administrative fee.

The amount is paid using the official fee form and must be settled before submitting the application. The cost of the NIE is €9.84 (or €7.31 if we need to update it).

How long does it take to obtain an NIE?

The timeframe may vary depending on where it is requested:

• If processed in Spain, the timing will depend on the office and administrative workload. In general, the processing time is usually around 2 weeks.

• If requested through a Consulate, the procedure may take longer, as the documentation is sent to Spain for processing.

For this reason, it is advisable to start the process with sufficient time within the purchase schedule.

Is an NIE the same as being a resident in Spain?

No. The NIE is simply an identification number. It does not imply obtaining residency or the right to live in Spain.

A foreigner can hold an NIE as a non-resident, simply to carry out economic transactions such as purchasing a property.

Can you buy property in Spain without an NIE?

No. The NIE is essential to formalise the public deed, pay taxes and register the property.

Therefore, any foreign buyer must obtain it in advance, even if they do not intend to reside in Spain.
