A NIE (Número de Identificación de Extranjero) is the tax identification number Spain issues to every foreigner. You must have one to buy Spanish property — it's used on the escritura, on tax filings (ITP, IVA/AJD, plusvalía, modelo 210), and to open a Spanish bank account. Three routes: (1) apply at a Spanish consulate in your home country — cleanest for buyers who won't be in Spain first; (2) apply at an extranjería office in Spain — for those already here; (3) apply through a lawyer with power of attorney — the standard for foreign buyers using a lawyer for conveyancing. Documents: passport, form EX-15, proof of economic reason (typically a preliminary property contract), fee. Timeline: 2–8 weeks depending on route and location. Cost: modest (fee is small) — most of the cost is representation. We handle NIE acquisition as part of buyer's conveyancing — book a consultation.
What a NIE Is
The NIE is a tax identification number issued to foreigners. It's the equivalent — for foreigners — of Spain's NIF/DNI for nationals. Key points:
- The NIE is numeric with a letter prefix and suffix — e.g. X-1234567-A or Y-1234567-B.
- It's assigned for life — once issued, you keep the same number forever, even if you stop having any connection to Spain and return years later.
- It's separate from residence — you can have a NIE as a non-resident with a Spanish holiday home, or as a resident with a TIE card (the residence card shows your NIE on it).
- The physical NIE certificate is a white A4 sheet — no plastic card unless you're a resident (in which case you get a TIE card).
- The NIE is what you write on Spanish tax filings, notarial deeds, contracts, bank accounts, mortgages and utility contracts.

Why You Need One
You cannot buy Spanish property without a NIE. Specifically:
The escritura pública
The Spanish notary needs your NIE to prepare and execute the deed of purchase — the escritura won't be signed without it.
Tax filings at purchase
ITP (resale) or IVA + AJD (new build) are declared with your NIE. Plusvalía and IBI (post-purchase) require NIEs on file.
Bank account
Spanish banks require a NIE to open a non-resident account (some allow you to open provisionally and provide the NIE within a short window).
Ongoing tax
Non-resident property tax (modelo 210) is filed under your NIE annually or quarterly.
Utility contracts
Electricity, water, internet, phone — Spanish providers routinely require NIEs to set up service.
Mortgage
Spanish mortgage applications require NIEs — banks won't proceed without.
Each co-owner needs their own NIE. A couple buying jointly need two NIEs — you can apply for them together, but each is separate.
The Three Routes
| Route | Best for |
|---|---|
| Spanish consulate abroad | Buyers not currently in Spain who want the NIE before travelling. Applied for by you in person at the consulate covering your area. |
| Extranjería in Spain | Buyers already in Spain (viewing trip, tourist stay). Applied for at a designated National Police foreigners' office or Oficina de Extranjería. |
| Through a lawyer with POA | Buyers not in Spain and not travelling. Your lawyer, with your power of attorney, applies at the extranjería in Spain on your behalf. |
Route 1: Spanish Consulate
You attend the Spanish consulate covering your area of residence (UK: London, Manchester, Edinburgh depending on where you live; US: various by state; other countries similar). Steps:
Book an appointment
Consulate booking systems are the bottleneck — appointments can be scarce, especially in high season. Book weeks ahead.
Gather documents
Passport, completed EX-15 form (in Spanish), proof of economic reason (typically your preliminary property purchase contract or an equivalent), fee proof (modelo 790).
Attend the appointment
Attend in person with the documents. The consulate takes the file and processes it, typically returning the NIE certificate by post or requiring collection.
Receive your NIE
2–8 weeks typically after the appointment, depending on the consulate.
The advantage: you have the NIE before travelling to Spain for signing. The disadvantage: consulate booking scarcity is the main risk; miss a signing window and re-booking can add weeks.
Route 2: Extranjería in Spain
You apply at a National Police foreigners' office or Oficina de Extranjería in Spain (which specific offices vary by region — provincial capitals and larger tourist centres typically have them). Steps:
Book cita previa
The online cita previa (prior appointment) system is essential — walk-ins aren't accepted. Availability is very variable and can be days to weeks.
Prepare documents
Passport (with copies), EX-15 form, proof of economic reason (preliminary property contract), modelo 790 fee proof (typically pay at a Spanish bank before the appointment).
Attend the appointment
Present the file in person. In many offices the NIE certificate is issued the same day (resolución en el acto); in others you return to collect it after processing.
The advantage: often faster than the consulate route if cita previa is available. The disadvantage: cita previa scarcity can be extreme in some regions, and you need to be in Spain.
Route 3: Through a Lawyer
Your lawyer, with your power of attorney, attends the extranjería in Spain on your behalf. Steps:
Sign a POA covering the NIE application
A specific POA authorising the lawyer to apply for your NIE. See our power of attorney guide. Can be signed at a Spanish notary (if you're briefly in Spain) or at a home-country notary with apostille and translation.
Provide documents
Certified passport copy, POA, EX-15, proof of economic reason.
Lawyer books cita previa and attends
The lawyer navigates the cita-previa system (often faster with professional access), attends the appointment, and collects the NIE.
Lawyer holds the NIE certificate
Sent to you or held for use in the transaction.
The advantage: fully hands-off; you don't need to travel or navigate booking. The disadvantage: requires the POA to be in place first, and the POA lead time (particularly home-country notary + apostille + translation) is 2–4 weeks. For most buyers using a lawyer for full conveyancing, this is the default route — the POA covers both NIE and the escritura signing, so it's a one-time setup.
Documents You Need
- Valid passport — full validity, with sufficient blank pages. Copies of the biodata page are typically provided; some offices want certified copies.
- EX-15 application form — completed in Spanish. Available from the Spanish Interior Ministry site; your lawyer completes it if using route 3.
- Proof of economic reason — typically the preliminary property purchase contract (reservation contract, arras, or private purchase contract) evidencing the reason you need the NIE. A letter from your lawyer confirming the intended transaction can supplement.
- Modelo 790 fee — the specific fee code for NIE applications. Paid at a Spanish bank branch (or online with a certificate) with the paid proof brought to the appointment.
- Photos — some offices require passport-style photos; check the specific office.
- For POA route — the POA original with apostille and sworn Spanish translation if signed abroad.
Documentation errors are a common cause of NIE-appointment rejection or delay — the biggest single mistake is turning up without the modelo 790 paid, or with an EX-15 completed in English or with wrong details.
Timing Your NIE
Getting the timing right is essential to keep your purchase timetable clean:
Start the NIE process the moment your offer is accepted
The NIE lead time (2–8 weeks) is longer than the average purchase runway. Starting NIE at reservation or arras signing gives you a buffer against consulate booking delays.
- NIEs typically take 2–8 weeks from application to certificate, depending on route and location.
- Consulate route can be materially longer at peak times.
- The extranjería-with-lawyer route is often the fastest in-country option.
- You can't sign the escritura without the NIE, so this becomes a critical-path item for the purchase.
- Joint buyers — each needs their own NIE; they can be applied for together, but time is required per applicant.
- NIE certificates don't expire, but many Spanish institutions (banks, tax offices) prefer to see a "recent" NIE certificate — practically, a NIE more than 3 years old sometimes needs re-confirmation.
NIE vs TIE vs NIF
NIE
The tax ID number itself. Assigned once, kept for life. Applies to any foreigner with a Spanish reason (property, work, tax filing).
NIE certificate
The physical white A4 sheet issued by the extranjería or consulate. Proves you have a NIE.
TIE
The Tarjeta de Identidad de Extranjero — plastic residence card for foreigners resident in Spain. Shows your NIE on the front. If you become a Spanish resident, you get a TIE and use it in place of the NIE certificate.
NIF
Número de Identificación Fiscal — the umbrella term for Spanish tax IDs, including both NIF (nationals) and NIE (foreigners). Sometimes NIE is casually called NIF in Spanish usage — practically, if you're a foreigner, your NIE is your tax ID.
For a non-resident foreign property buyer, you need a NIE (not a TIE) — the NIE certificate is enough. If you subsequently become a Spanish resident, you'll swap the certificate for a TIE card, but your NIE number stays the same.
After You Have Your NIE
- Keep the certificate safe — you'll need copies (or the original) for the escritura, bank account, tax filings and utility contracts.
- Give a copy to your lawyer for the transaction file.
- Use it consistently — every Spanish transaction from this point uses your NIE.
- Open your Spanish bank account — with NIE, passport and proof of address. Non-resident accounts are simpler than resident accounts.
- Progress the escritura — the NIE is one of the last pieces to unblock signing.
- Post-purchase — your NIE will be used for modelo 210 filings, IBI direct debits, and community-fee registrations. Keep it accessible.

Frequently Asked Questions
Yes — Spanish law requires that any foreigner buying property in Spain has a NIE. The notary won't sign the escritura without it; ITP or IVA/AJD tax filings won't be accepted; a Spanish bank account can't be opened; and utility contracts won't be set up. Each buyer needs their own NIE — a couple buying jointly needs two. It's a foundational step; without it, none of the other purchase steps can proceed. Start the NIE application the moment your offer is accepted to avoid holding up the escritura.
Depends on your situation. If you're not travelling to Spain before signing, a consulate application in your home country lets you have the NIE in hand before travel — but consulate booking can be slow (weeks or more) and the consulate route can take longer overall. If you're going to be in Spain for viewings, applying at the extranjería while there is often faster. If you're using a lawyer for full conveyancing and have a power of attorney, letting the lawyer handle the NIE at the extranjería in Spain is often the cleanest route — the POA covers it plus the signing.
Typically 2–8 weeks from application to certificate, depending on route and location. Consulate applications can be at the longer end because of booking scarcity plus processing time. Extranjería applications in Spain vary hugely by office and cita previa availability — some offices issue same-day (resolución en el acto), others take weeks to book and further weeks to process. Lawyer-led applications via POA are typically fastest in-country. Start the NIE process early — it's often the critical-path item in a purchase.
Passport (with copies of the biodata page), completed EX-15 form in Spanish, proof of the economic reason for needing the NIE (typically your preliminary property purchase contract or a lawyer's letter confirming the intended transaction), proof of the modelo 790 fee paid, and — depending on the office — passport-style photos. Applications via power of attorney also need the POA original, apostille and sworn Spanish translation if signed abroad. Documentation errors (EX-15 completed in English, fee not paid before the appointment) are common causes of rejection.
Yes — with a power of attorney authorising the NIE application. This is the standard approach for foreign buyers using a lawyer for full conveyancing, because the same POA also covers the escritura signing, tax filings and utility transfers, so it's a single POA covering everything. Your lawyer applies at the extranjería on your behalf, handles the cita previa and documentation, and holds the NIE certificate for use in the transaction. You don't need to travel to Spain at all if this route is used.
The Spanish state fee itself (modelo 790) is small — under €20 at current rates. The main cost is in the process — consulate visit (travel to consulate, possibly repeat visits if slots are scarce), or lawyer representation with power of attorney (POA drafting, apostille if abroad, sworn translation, lawyer's time). For a lawyer-led NIE via POA, expect several hundred euros all-in as part of a conveyancing package. Standalone NIE-only work is available but less common — most buyers roll it into full conveyancing.
The NIE number itself is for life — once assigned, you keep it forever, even if you never return to Spain. The NIE certificate (the physical white A4 sheet) doesn't formally expire, but many Spanish institutions (banks especially) prefer to see a "recent" certificate — practically, an NIE certificate more than 3 years old sometimes needs re-confirmation or a fresh certificate issued. If you become a Spanish resident, you'll get a TIE card showing your NIE, and use the TIE instead of the certificate.
The signing doesn't happen. The notary won't execute the escritura without your NIE, so the completion is delayed until you have it. This can trigger contractual issues if the sale contract has a deadline, penalties for delay, or a nervous seller looking for a way out. Starting the NIE process the moment your offer is accepted, using the lawyer-led POA route where possible, and building buffer into the completion date all help avoid this scenario. If you're already at signing week without a NIE, treat it as an emergency — expedited routes exist but they're stressful and expensive.
