How to Get Your NIE Number in Spain: The 2026 Guide for UK Buyers

The NIE number is the first bureaucratic hurdle you'll face when buying property in Spain, and it trips up more UK buyers than any other single step. Not because it's difficult — it's not — but because the process is poorly documented, inconsistent between locations, and the appointment booking system can be genuinely frustrating.

Here's everything you need to know.

What Is a NIE?

NIE stands for Número de Identidad de Extranjero — literally "Foreigner's Identity Number." It's a unique tax identification number assigned to non-Spanish nationals. It is not a residency permit. It doesn't give you the right to live or work in Spain. It's simply an identification number that Spain uses to track your tax and legal obligations.

You need a NIE to:

• Buy or sell property
• Open a Spanish bank account
• Sign a rental contract
• Pay Spanish taxes
• Connect utilities (electricity, water, gas)
• Buy a car
• Start a business

Once issued, your NIE number is permanent. It doesn't expire or need renewing, though the physical certificate can expire (usually after 3 months) and may need to be re-issued for certain transactions.

Option 1: Apply From the UK

You can apply at one of Spain's three consulates in the UK:

• London: 20 Draycott Place, SW3 2RZ
• Manchester: Suite 1A, Brook House, 70 Spring Gardens, M2 2BQ
• Edinburgh: 63 North Castle Street, EH2 3LJ

The process:

1. Book an appointment through the consulate (check their website for the current booking system — it changes)
2. Fill in form EX-15 (available as a PDF on the consulate website)
3. Pay the fee: Tasa 790-012, approximately €12 (payable in GBP equivalent at the consulate)
4. Bring your passport (original plus photocopy) and a cover letter explaining why you need the NIE (property purchase is a standard accepted reason)
5. Attend in person

Typical processing time: 2–4 weeks. Some consulates have been known to take longer. The London consulate tends to be the busiest.

Option 2: Apply in Spain

You can apply in person at any Policía Nacional office in Spain that handles foreigner documentation (Oficina de Extranjería). This is faster in theory — sometimes same-day — but the appointment system is the bottleneck.

The appointment booking website (sede.administracionespublica.gob.es) is notoriously overloaded. Appointments in Málaga, Barcelona, and Madrid are frequently unavailable weeks in advance. Tips that actually work:

• Check the booking site early morning (7–8am Spanish time) when new slots are released
• Try smaller cities — Almería, Huelva, Jaén, Castellón all have shorter waits
• Some gestoría offices (administrative consultants) can book appointments on your behalf for a fee of €50–100
• Your lawyer may be able to apply on your behalf with a power of attorney

What you need in Spain:

• Passport (original plus photocopy of the photo page)
• Completed form EX-15
• Paid Tasa 790-012 (pay at a Spanish bank first, bring the stamped receipt)
• Proof of reason (property purchase contract, reservation agreement, or a letter from your lawyer)
• Two passport-sized photos (some offices require them, some don't — bring them to be safe)

Common Mistakes

• Waiting too long to apply. Start the NIE process as soon as you're serious about buying. Don't wait until you've found a property — by then, you'll be racing against the reservation timeline
• Not paying the fee in advance. In Spain, the Tasa must be paid at a bank before your appointment. You can't pay at the police station
• Wrong form. The EX-15 is for a NIE number. The EX-18 is for a TIE (identity card for EU citizens). Don't mix them up
• Expired certificate. The paper NIE certificate typically has a 3-month validity stamp. The number itself never expires, but some notaries and banks insist on a certificate issued within the last 3 months. If yours has expired, you may need to get a new certificate (same number, new paper)

How Long Does It Take?

Route	Appointment Wait	Processing	Total
UK Consulate	1–2 weeks	2–4 weeks	3–6 weeks
Spain (Málaga/Barcelona)	2–6 weeks	Same day – 1 week	2–7 weeks
Spain (smaller cities)	Few days – 2 weeks	Same day	Few days – 2 weeks
Via gestoría/lawyer	Variable	Variable	1–4 weeks

The single best piece of advice: apply for your NIE the moment you start seriously looking at property in Spain. Not when you find one. Not when you put in an offer. The moment you start looking.
