NIE Number in Spain: Complete Guide for Families (2026)

What Is a NIE Number and Why Families Need One

If you are moving to Spain with children — or buying a holiday home there — the NIE (Número de Identificación de Extranjero, or Foreigner ID Number) is the single piece of paperwork that unlocks everything else. Without it, you cannot open a bank account, enrol your kids in school, sign a rental agreement, or register with a Spanish GP. This guide covers everything British and Irish families need to know in 2026, including what has changed since Brexit and how to apply for children as well as adults.

What Is a NIE Number and Why Families Need One

A NIE is Spain’s permanent tax and foreigner identification number assigned to every non-Spanish national who has legal, financial, or administrative dealings in the country. Think of it as the Spanish equivalent of a National Insurance number — a unique reference that follows you across every official transaction.

The number looks like this: X1234567A — a letter, seven digits, then a second letter. Once issued, it never changes or expires, whether you use it every month or once a decade.

It is worth understanding the difference between a NIE and a TIE (Tarjeta de Identidad de Extranjero, or Foreigner Identity Card). The NIE is simply the number itself; the TIE is a physical residency card that carries that number. Families buying a holiday home or completing a short financial transaction may only ever need the NIE number. Families relocating permanently will eventually apply for a TIE — but the NIE comes first and underpins everything.

A NIE is legally required for:

• Buying or selling property
• Opening a Spanish bank account
• Filing taxes as a resident or non-resident
• Setting up utilities (electricity, water, internet)
• Signing a rental agreement or mortgage
• Starting a business or taking up employment in Spain
• Enrolling children in the Spanish school system

Crucially, every family member — including infants and young children — needs their own separate NIE. A parent’s NIE cannot be used on a child’s behalf.

When to Apply: School Enrolment, Property and Healthcare

When to Apply: School Enrolment, Property and Healthcare

The golden rule is: apply before you need it. Timelines typically run two to six weeks from booking your appointment to holding the certificate in hand. In smaller cities such as Alicante, you may wrap it up in under a fortnight. In Madrid or Barcelona, particularly during summer, expect to wait closer to six weeks.

School enrolment is the most urgent trigger for many families. To register your child at a colegio (primary school) or secondary school in Spain, the school or the local authority will ask for the child’s NIE. Choosing between state, concertado (semi-private), and international schools is a major decision, but none of those processes can begin without the NIE in place for each child. See our guide to enrolling children in Spanish schools for the full picture.

Property purchase is another common trigger. Estate agents and notaries will ask for your NIE from the very first stage — including when signing a reservation contract. Apply well before you travel for viewings.

Healthcare: registering with the Spanish public health system and obtaining a tarjeta sanitaria (health card) for each family member requires a NIE and local registration known as empadronamiento (registering your address at the ayuntamiento, or town hall). See our article on registering for healthcare in Spain as a UK family for step-by-step detail.

Start your NIE applications as soon as you have confirmed your move or purchase — not after you arrive.

How to Apply for a NIE in Spain Step by Step

There are three legally recognised routes: applying in person in Spain, applying through the Spanish consulate in your home country, or using a qualified legal representative acting under a notarised power of attorney.

Route 1 – Apply in Spain

How to Apply for a NIE in Spain Step by Step

This is the most common option for families already in the country. You apply at the Comisaría de Policía Nacional (National Police headquarters) or the Oficina de Extranjería (immigration office) in the province where you intend to live.

1. Book a cita previa (appointment) at sede.administracion.gob.es. In larger cities, slots can fill up weeks in advance.
2. Complete form EX-15 for each applicant — available to fill in online and print.
3. Pay the administrative fee via the modelo 790 (código 012) form — approximately €10 (about £8.50) [do uzupełnienia: confirm exact 2026 rate] per person, payable at a Spanish bank before your appointment.
4. Attend the appointment with all original documents and photocopies.
5. Receive your NIE certificate on the day or return to collect it within the stated timeframe.

Route 2 – Apply at the Spanish Consulate in the UK

For families still based in the UK, the Spanish Consulate General in London handles NIE applications. Contact the consulate by emailing [email protected] to request an appointment. Physical presence is mandatory — you cannot submit by post. The document requirements are the same as applying in Spain.

Route 3 – Through a Legal Representative

A Spanish lawyer or gestor (administrative agent) can apply on your behalf under a notarised power of attorney. This adds cost but suits families managing the process entirely from the UK.

Since Brexit, UK citizens are treated as third-country nationals rather than EU nationals, which means slightly more documentation may be expected — but the NIE process itself remains straightforward.

Documents Required for Children and Adults

Prepare the following for each applicant, including every child:

Documents Required for Children and Adults

• EX-15 form — completed online and printed, but left unsigned until instructed at the appointment. The form must state the reason for needing a NIE (school enrolment, property purchase, employment, etc.).
• Valid passport — original plus a photocopy of the biographical data page.
• Proof of reason for the NIE — for example, a school acceptance letter, property reservation contract, or employment offer.
• Modelo 790 fee receipt — approximately €10 (about £8.50) [do uzupełnienia: confirm exact 2026 rate], paid at a Spanish bank in advance.

For children, the process requires extra attention. Spain’s electronic immigration system does not permit anyone under 18 to be listed as the direct applicant. A parent or legal guardian must submit the application on the child’s behalf, selecting the “on behalf of a third party” option when logging in to the Sede Electrónica de Extranjería. Entering the child’s date of birth as the primary applicant will result in an automatic rejection.

Additional documents for children typically include:

• Birth certificate (original and copy)
• If issued outside Spain: an apostille stamp plus a sworn Spanish translation (traducción jurada)
• Documentation confirming parental responsibility or legal guardianship

UK birth certificates can be apostilled via the FCDO Legalisation Office [do uzupełnienia: current processing times and fees].

Common Mistakes Families Make (and How to Avoid Them)

Leaving it too late. The process averages two to six weeks, not counting the time needed to book an appointment. Start immediately once you have confirmed your move, school choice, or property.

Forgetting each child needs a separate NIE. Every child requires their own EX-15 form, their own fee payment, and ideally their own appointment (or a joint family appointment at a police station that accommodates groups).

Common Mistakes Families Make (and How to Avoid Them)

Applying for a child as if they were an adult. On Spain’s electronic portal, entering a minor’s date of birth as the primary applicant triggers an automatic error. You must always apply as the legal guardian acting on the child’s behalf.

Incomplete or uncertified documents. For UK passport holders post-Brexit, missing documents are the most frequent cause of rejected appointments. Any document in English may need a sworn translation — check with the specific office in advance.

Confusing the NIE with residency. A NIE does not grant the right to live in Spain long-term. If your family plans to stay beyond 90 days in any 180-day period, you will also need to apply for a TIE residency permit. The NIE and TIE are different things.

Not bringing enough photocopies. Spanish administrative offices routinely ask for both originals and one or two copies of every document. Bring extras — it saves a wasted trip.

NIE Number FAQs for Families Moving to Spain

Does a baby or very young child need a NIE?

Yes, if your child will be enrolled in school, registered with the health service, or named in any legal or financial document in Spain, they need their own NIE regardless of age. A parent applies on their behalf.

How long does the NIE process take in 2026?

Between two and six weeks from appointment to collection, depending on location and season. Busy offices in Madrid and Barcelona tend to take longest, especially July to September.

NIE Number FAQs for Families Moving to Spain

Can I apply for a NIE from the UK before moving?

Yes. The Spanish Consulate General in London processes NIE applications for UK residents. Email [email protected] to arrange an appointment. Physical attendance is required.

What is the difference between a NIE and a TIE?

A NIE is a number; a TIE is a physical card. Non-residents buying property or making financial transactions generally only need the NIE number. Families relocating to Spain permanently will eventually apply for a TIE residency card, which carries the same NIE number.

Does a NIE expire?

No. Once issued, your NIE is permanent, even if you leave Spain for several years.

How much does a NIE cost per person?

The administrative fee (paid via modelo 790, código 012) is approximately €10 (about £8.50) per applicant [do uzupełnienia: confirm exact 2026 rate]. You pay at a Spanish bank before your appointment. Each child needs a separate payment.
