The NIE (Número de Identidad de Extranjero) is the first thing you need if you plan to buy, rent or own property in Torrevieja, Orihuela Costa or anywhere else in Spain. Without it a notary will not sign your deed, a bank will not open a normal account and the tax office cannot register you as an owner. It is a personal tax and identification number for foreigners, and once issued it stays with you for life. This guide explains the three realistic ways our clients obtain it: in person in Spain with a cita previa, from abroad at a Spanish consulate, or through a lawyer acting under a power of attorney, together with the documents that trip people up and the timing you should plan around.
What the NIE is, and what it is not
The NIE is an identification number, usually starting with X, Y or Z, followed by seven digits and a control letter. It identifies you in every dealing with the Spanish administration: the notary, the land registry, the tax agency (Agencia Tributaria), the town hall for IBI property tax, utility companies and banks.
What the NIE is not is a residence permit. Having a NIE does not allow a non-EU citizen to live in Spain for more than the usual visitor period, and buying a home does not create any right to reside. This matters more than ever now that Spain's golden visa, which linked residence to a property investment of 500,000 euros or more, was abolished for new applications on 3 April 2025. If you want to live here, the NIE is only the starting point; residence is a separate procedure with its own requirements.
For EU citizens who move here permanently, the NIE appears on the green EU registration certificate. For non-EU residents it is printed on the TIE card. Non-resident buyers simply receive a NIE certificate, which is all you need to complete a purchase.
When exactly you need it in a property purchase
You can view homes, make an offer and even sign a reservation document without a NIE, but you cannot sign the public deed (escritura) at the notary without one. In practice you should start the application as soon as you are serious about buying, because you will also need it to:
- open a Spanish bank account to pay the price, taxes and running costs;
- pay transfer tax (ITP) on a resale or IVA on a new build under your own name;
- apply for a Spanish mortgage;
- put water, electricity and internet contracts in your name;
- file the annual non-resident income tax return (Modelo 210) that every non-resident owner must submit.
If you are buying as a couple, each buyer needs their own NIE, even if only one of you will be dealing with the paperwork. The same applies if you add a child or partner to the title. Browse our homes for sale knowing that your NIE timing, not the property, is often what sets the completion date.
Route 1: applying in person in Spain with a cita previa
If you are on the Costa Blanca for viewings, the most direct route is to apply at a National Police foreigners' office (Oficina de Extranjería or Comisaría with a foreigners' desk). Buyers in Torrevieja and Orihuela Costa usually apply in the province of Alicante, choosing whichever office has appointments available.
The key obstacle is the cita previa, the mandatory online appointment. It is booked on the government's appointments portal by selecting the province of Alicante and the procedure for NIE certificates. Slots are released irregularly and can disappear within minutes, especially in spring and autumn when the coast is busy. Many buyers check early in the morning over several days; this is one reason people hand the job to a lawyer or gestor.
On the day you normally bring:
- the EX-15 application form, completed and signed;
- your original passport plus a photocopy of the main page;
- proof of the reason for the application, for example a reservation contract, an offer letter or a letter from your lawyer explaining the purchase;
- proof of payment of the fee on form 790, code 012, paid at a Spanish bank before the appointment.
The fee is small and updated periodically; generate the form on the National Police website so it shows the exact current amount. In many offices the certificate is issued the same day or within a few days, but it varies.
Route 2: applying from abroad at a Spanish consulate
If you cannot travel before the purchase, you can apply at the Spanish consulate that covers your place of residence. The consulate forwards the file to the Spanish police, and the certificate is sent back to the consulate or, in some cases, delivered electronically.
Each consulate sets its own booking system and document checklist, so check its website first. Expect to provide the EX-15, your passport, a justification of the reason (again, the reservation contract or a lawyer's letter works well) and payment of the fee in the form the consulate accepts. Processing times depend on the consulate and on the volume of applications in Spain; allow several weeks and do not fix a completion date until you have the number in hand.
This route suits buyers who have found a property on a previous visit and want to prepare the purchase from home. Citizens of some countries may face longer processing or additional checks, so ask the consulate early rather than assuming a standard timeline.
Route 3: a lawyer obtaining it with your power of attorney
The route most of our international buyers choose is to grant a power of attorney (poder notarial) to an independent Spanish lawyer, who then applies for the NIE on your behalf and, with the same document, can open your bank account, sign the purchase deed, pay taxes and register the property.
The power can be signed at a notary in Spain during your viewing trip, which is usually the simplest option. It can also be signed abroad at a Spanish consulate or before a local notary; a foreign notarial document will normally need the Hague Apostille and a sworn translation into Spanish. Ask your lawyer to draft the text in advance so that it covers exactly what you need, no more and no less.
A good lawyer also knows which offices in Alicante province currently have appointments and how to present the justification of the purchase. Because the lawyer is working for you, not for the seller or the agency, the same person can check the property's legal status, debts and licences. If you need an introduction to an independent lawyer in Torrevieja or Orihuela Costa, contact us and we will share names we have worked with.
Common mistakes that delay the NIE
- Names that do not match. The name on the NIE must match your passport exactly, including middle names. A mismatch will reappear on the deed and the land registry.
- Weak justification. An application stating only that you want to buy something in Spain is often refused; attach a concrete document.
- Wrong fee form. Form 790 code 012 lists several procedures; tick the one for the NIE certificate.
- Waiting until the last week. The appointment, not the processing, is usually the bottleneck. Start as soon as you reserve a home.
- Confusing NIE and residence. If you plan to spend more than 90 days in any 180-day period in Spain as a non-EU citizen, you need a visa or residence permit, which the NIE does not replace.
After you have the NIE: the next steps in Torrevieja and Orihuela Costa
Keep several scanned copies of the certificate: the bank, the notary, the utility companies and your tax representative will all ask for it. The number never changes, but some banks and notaries prefer a recent certificate, so ask them before completion.
With the NIE ready you can open your account, sign the private purchase contract and fix a date at the notary. If you are still deciding where to buy, compare the established town centre and beaches of Torrevieja with the newer developments and golf areas of Orihuela Costa, such as La Zenia, Cabo Roig and Villamartín. Once you own, the NIE is also the number under which you pay IBI to the town hall and file the annual Modelo 210, so share it with whoever manages your taxes.
