To buy a property in Spain you need an NIE, the Foreigner Identity Number: without it you cannot sign the deed, open a bank account or take out a mortgage. You apply using form EX-15, pay a €9.84 fee via tax form 790 code 012, and can do it in Spain, at the Spanish consulate in your own country, or through a representative holding power of attorney, with no need to travel.
What the NIE is, and what it is not
It is the number Spain assigns to any foreign national with economic, professional or social interests in the country. It is personal, unique and does not expire: you obtain it once and it serves you for life. The format is an initial letter (X, Y or Z), seven digits and a final check letter.
It is worth being clear about what it does not do, because this is where most confusion arises: the NIE does not grant the right to live in Spain or to work here. It is a tax and administrative identifier, nothing more. If your plan is to move, the NIE is the first step but not the only one.
NIE, TIE, NIF and the green certificate: what each one is
- NIE: the identification number itself. This is what you need in order to buy a property.
- TIE: the physical foreigner identity card, tied to a residence permit. It is a separate procedure.
- NIF: the tax code used with the Spanish tax office. For a foreign national it normally matches their NIE.
- The so-called green NIE is in fact the EU citizen registration certificate, applied for with form EX-18, which evidences residence rather than mere identification.
What paperwork do you need to prepare?
- Form EX-15, completed and signed. This is the NIE assignment application, not to be confused with EX-17 or EX-18.
- A valid passport or identity document, original plus a copy of every page.
- Proof of payment of the fee, tax form 790 code 012, for €9.84.
- A written explanation of why you are applying, with supporting documentation: a deposit contract, property reservation, purchase offer or a letter from the notary.
- If someone else handles it for you, express power of attorney for that specific procedure, apostilled and officially translated if granted outside Spain.
The fourth point is what sinks most applications. Saying you intend to buy a house is not enough: you have to evidence that the transaction exists. A signed reservation or a letter from the notary settles that requirement in a single page.
Where do you apply, and what does each route cost?
| Route | Indicative cost | When it makes sense |
|---|---|---|
| Immigration office or police station in Spain | €9.84 fee | If you are already here and can get an appointment |
| Spanish consulate in your country | €9.84 plus consular fees | If you have not travelled yet and are not in a hurry |
| Representative with power of attorney | €9.84 plus notary, apostille and fees | If you would rather not travel just for this |
| Full-service private provider | From €179, with optional extras | If you would rather delegate everything and pay for it |
The official fee is the same in every case: what varies is how much you pay to avoid handling it yourself. For reference, a typical private provider starts at €179 for the basic service and charges separately for extras such as the FNMT digital certificate (€149) or courier delivery (€79). These do not cover notary fees, apostilles or translations.
How long does it really take?
The National Police resolve the procedure within a maximum of five days from the application entering the register. That timescale sounds excellent until you understand when the clock starts: from the formal entry of the file, not from the moment you decide to apply.
What really drives the calendar is everything that comes before: securing an appointment, having the consulate forward the file, granting the power of attorney before a notary, apostilling and translating it. All told, the sensible assumption is several weeks, and you should start as soon as you have reserved a property, not once the signing date is already set.
The mistakes that delay an NIE most
- Filing the wrong form: EX-18 is for EU citizen registration, not for NIE assignment.
- Claiming an intention to buy without documenting the specific transaction behind it.
- Discrepancies between the name on the passport and on the other documents, including accents and surname order.
- A generic power of attorney that does not expressly mention the NIE application.
- Assuming the NIE grants the right to live or work here, and finding out too late.
When should you apply if you are buying on the Costa del Sol?
In a typical purchase in Marbella, Estepona or Mijas, the sensible sequence is: reserve the property, sign the deposit contract, and start the NIE at that very moment. One to three months usually pass between the deposit contract and the deed, which is enough time if you start on day one and distinctly tight if you leave it to the end.
One detail is often forgotten: if you are buying as a couple or with several co-owners, every person who will appear on the deed needs their own NIE. And if you are financing the purchase, the bank will ask for it before it even assesses the application, so in practice it is the very first step of all.
Conclusion
The NIE is a cheap, straightforward formality that becomes a problem for one reason only: leaving it until last. A fee of nine euros and eighty-four cents, one form and a document evidencing your transaction are all it takes. What the calendar will not forgive is starting the week before completion.
At EVS PROPERTY GROUP we support this step in every purchase by an international client, coordinating the power of attorney, the appointment and the paperwork with the notary and the bank so the NIE is never the reason a completion slips. If you are considering buying on the Costa del Sol and want to know exactly what you need in your case, get in touch and we will organise it with you, with no obligation.
Frequently asked questions
Can you buy a property in Spain without an NIE?
No. The NIE is essential to sign the public deed, settle the purchase taxes and register the property in your name at the Land Registry. The bank will also require it to open an account or grant a mortgage.
How much does the NIE cost in 2026?
The official fee is €9.84, paid using tax form 790 code 012. Depending on the route you choose, you should add consular fees, notary and apostille costs for the power of attorney, sworn translations or agency fees if you delegate the process.
Can you obtain an NIE without travelling to Spain?
Yes, in two ways: applying at the Spanish consulate in your country of residence, or appointing a representative in Spain through a power of attorney that expressly mentions this procedure, duly apostilled and translated.
Does the NIE expire?
The number itself does not expire: it is personal and unique for life. What can carry a validity date is the paper document evidencing it, which is why some institutions ask for a recent certificate. The number, however, never changes.
Does each buyer need an NIE if we buy as a couple?
Yes. Every person listed as an owner on the deed needs their own NIE, without exception. It is best to start both applications at the same time, since a delay to either one will hold up the signing just as effectively.
