NIE Number Explained: How to Get Yours Before You Buy in Spain
A step-by-step guide for British buyers — where to apply, what it costs, and how long it takes in 2026
Last updated: 15 August 2026
If you're buying a property on the Costa Blanca or Costa Cálida, the NIE (Número de Identidad de Extranjero) is the single document that has to be in your hand before the notary will sign your deed. It's a personal ID number for foreigners, issued by the Spanish National Police, and it costs €9.84 in official state fee. Getting it wrong — or leaving it until three weeks before completion — is the most common reason British purchases stall at the last minute.
Here's exactly what the NIE is, why every buyer needs their own, and the three legitimate ways to get one from the UK — with realistic 2026 timelines so you can plan your purchase properly.
What is an NIE, in one sentence
An NIE is a permanent tax and identification number assigned to non-Spanish nationals who have any economic, professional, or administrative link with Spain — buying a property is the most common trigger. It follows the format of a letter, seven digits, and a check letter (for example, Y-1234567-A), and once assigned it's yours for life.
Two clarifications that trip British buyers up:
- The NIE number itself never expires, but the paper certificate you receive is often treated by banks and administrations as having a practical validity of three months — according to Granfield Estate's 2026 NIE guide. For a property purchase, the number is what matters; if the certificate is old, some banks may ask for a fresh copy.
- An NIE is not a residency permit. If you plan to spend more than 90 days at a time in Spain post-Brexit, you'll separately need a visa and, later, a TIE (Tarjeta de Identidad de Extranjero). The NIE is the foundation, not the whole building.
Why you need one before you buy
Without an NIE you cannot:
- Sign the escritura pública (title deed) at the notary — the deed cannot be drafted without it
- Open a Spanish non-resident bank account to transfer funds and pay the vendor
- Pay the property transfer tax (ITP for resales) or IVA (for new-builds), or file the non-resident income tax return you'll owe every year
- Have utilities, community fees, or a mortgage put in your name
If two people are buying jointly, each buyer needs their own NIE — including a spouse, business partner, or any child listed as co-owner on the deed. Parents apply on behalf of minors.
The three ways to get an NIE from the UK
British buyers have three routes. Which one is right for you comes down to how quickly you need it and whether you're planning to travel to Spain before completion.
Route 1: Apply in person in Spain
Book a cita previa (appointment) through the Spanish government portal at sede.administracion.gob.es, then attend a ComisarÃa de PolicÃa Nacional with an extranjerÃa (foreigners) office. In smaller Costa Blanca towns the number is often issued the same day; the real bottleneck is appointment availability, which in busy provinces like Alicante can run 4 to 8 weeks per Gentle Van Removals' May 2026 guide.
Route 2: Apply through a Spanish consulate in the UK
Three Spanish consulates in the UK issue NIEs — London, Manchester, and Edinburgh — and you must apply to the one whose catchment area covers your county, not necessarily the nearest one. Processing at the London consulate is typically 2 to 6 weeks once you have your appointment, according to British Life in Spain (April 2026); Edinburgh and Manchester tend to be faster.
Route 3: Grant power of attorney to a Spanish lawyer or gestor
Sign a Power of Attorney (poder notarial) in front of a UK notary, get it apostilled by the FCDO Legalisation Office (standard postal service around £30 per document), have it sworn-translated, and your Spanish lawyer applies for the NIE without you setting foot in Spain. This is the route most buyers take when they've already found a property and need to move fast. Total timeline typically 2 to 6 weeks, per Vista-Mundo's February 2026 UK buyers' guide.
How the three routes compare
| Route | Typical total time | Official state fee | Best for |
|---|---|---|---|
| In person in Spain | 1–8 weeks (mostly appointment wait) | €9.84 | Buyers already visiting to view properties |
| UK consulate (London / Manchester / Edinburgh) | 2–6 weeks (London), faster at Edinburgh/Manchester | €9.84 | Buyers still in the UK with time before completion |
| Power of attorney (Spanish lawyer) | 2–6 weeks | €9.84 + PoA + apostille + gestor fees (typically €200–€500 all-in) | Buyers under time pressure who can't travel |
Documents you'll need
Whichever route you choose, the file is the same:
- Completed Form EX-15 (Solicitud de Número de Identidad de Extranjero y Certificados), downloadable from the PolicÃa Nacional website
- Paid Modelo 790 código 012 receipt — the state fee is €9.84 in 2026 per Spanienfastigheter's July 2026 guide, paid at any Spanish bank before your appointment
- Valid passport plus a photocopy of the identification pages
- A short written justification of why you need the NIE — a signed reservation contract or note from your Spanish lawyer confirming a purchase in progress is normally sufficient
Timing your NIE around your purchase
Our practical advice: start the NIE process the day you decide you're seriously looking to buy, not the day you've signed a reservation. On the Costa Blanca and Costa Cálida, a straightforward resale purchase from reservation to notary can complete in 6–8 weeks — which is exactly the window in which NIE appointments in Alicante province tend to slip. If the number isn't ready, completion is pushed back, and in some cases the vendor keeps your deposit.
DirecSpain lists properties in Torrevieja, Orihuela Costa, Villajoyosa and across the Costa Blanca directly from local agencies — with no buyer commission — so you can shortlist and reserve while your NIE is being processed in parallel.
Frequently asked questions
Does my NIE ever expire?
No. The number itself is assigned once and is permanent. The paper certificate is sometimes treated as having a three-month practical validity by banks or government offices, but the number stays with you for life.
Do I need to be resident in Spain to have an NIE?
No. Most British buyers apply as non-residents specifically to buy a holiday home or investment property. The NIE just identifies you to Spanish authorities; it doesn't oblige you to live in Spain or file resident tax returns.
Can my Spanish lawyer get the NIE for me?
Yes. With a notarised, apostilled, translated Power of Attorney granted to your Spanish lawyer or gestor, they can file EX-15 and collect the certificate without you travelling. This is the most common route for buyers on a tight completion timeline.
What does the whole thing cost?
The state fee is €9.84 (Modelo 790, código 012). If you use a Spanish gestor with power of attorney, the all-in cost typically runs €200 to €500 per e-Residence's May 2026 breakdown, plus UK-side apostille (around £30) and sworn translation.
Do both spouses need an NIE if we're buying together?
Yes. Every person named as a buyer on the escritura needs their own NIE, including spouses, business partners, and any children listed as co-owners on the deed.
Can I open a Spanish bank account without an NIE?
You can usually open a non-resident account with just your passport, but you'll need the NIE to transfer larger sums, receive a mortgage, or link the account to a property purchase. It's cleaner to get the NIE first.
The bottom line
The NIE is a €9.84 form, but it's the bureaucratic gatekeeper of the entire Spanish property purchase. Start it early, pick the route that fits your timeline, and don't let it be the thing that delays completion. If you're already speaking to a Spanish lawyer about a purchase, the power-of-attorney route is almost always the safest bet.
