NIE in Spain: what it is and when it is needed

The NIE, or Número de Identidad de Extranjero, is the personal, unique identification number Spanish authorities use for foreign nationals. It appears in official documents and administrative records connected to that person.

Many residence and EU registration procedures assign an NIE automatically as part of the process, so most people never need to file a standalone request.

A separate NIE application is only relevant when you need the identifier for a formal economic, professional or social matter before any residence process would assign one — for example a property transaction, company-related formalities, or a tax or administrative procedure where the authority handling it requires the number.

The exact need depends on the transaction and the receiving authority: a bank account enquiry, property viewing or short visit does not automatically require one.

According to Spain's Ministry of the Interior, a person requesting an NIE separately must not be in Spain irregularly and must communicate the reasons for the request.

Form: EX-15 (Solicitud de Número de Identidad de Extranjero) · Fee: modelo 790, código 012.

• EX-15 — the official NIE application form, completed and signed.
• Fee 790, code 012 — proof that the corresponding fee has been paid.
• Passport or identity document — original and copy of a valid full passport, identity document, travel document or registration certificate, as applicable.
• Documented reason — evidence or explanation of the economic, professional, social or other reason supporting the request.
• Representative’s authority — where a representative files the request, proof of sufficient authority expressly allowing that person to submit it.

The Ministry of the Interior sets out three official submission routes for a separate NIE request:

1. Personally in Spain, at the relevant Foreigners Office or Police Station.
2. Through a legally authorised representative in Spain, who must evidence sufficient power expressly allowing the submission.
3. From your country of residence, through the Spanish consular office with jurisdiction over that place.

Whichever route applies, the file is built around the same core: EX-15, the 790 code 012 fee, identity document and the documented reason.

Appointment availability and local submission arrangements vary. A fixed turnaround time cannot be guaranteed.

• Applying for an NIE when the number will already be assigned through a residence or EU registration procedure.
• Treating the NIE as proof of legal residence or permission to work.
• Attending without evidence explaining the formal reason for the request.
• Confusing the NIE number with the TIE card.
• Assuming every authority accepts the same supporting documents.

• Ministry of the Interior — Documentación de las personas extranjeras (NIE)
• Ministry of Inclusion — Modelos generales (official EX forms)

Official requirements and appointment procedures can change. Check the competent authority before filing.
