NIE number for property buyers in Spain

What the NIE is, in law

Article 205.1 of the immigration regulation says that foreigners “que por sus intereses económicos, profesionales, sociales o de cualquier otra índole, se relacionen con España” receive a personal, unique and exclusive sequential number. The number follows you to every document you are issued. It is not a residence permit: the consulate page for London states that a NIE obtained through a consular office “does not entitle the holder to reside in Spain or prove residence there”.

The regulation in force is Real Decreto 1155/2024 of 19 November, which entered into force six months after publication, on 20 May 2025, and repealed the 2011 regulation. Some consular pages still quote the 2011 decree. The NIE article is the same in substance, but cite the new text.

Why a buyer needs one

Three reasons, all grounded in the texts:

1. Tax number. Article 20 of Real Decreto 1065/2007 says that for individuals without Spanish nationality, the tax identification number (número de identificación fiscal) is the NIE assigned under the immigration law. Article 18 states that you need a tax number for dealings with tax relevance, and a purchase has them: transfer tax, stamp duty, and later the non-resident return.
2. The deed. Article 254.2 of the Ley Hipotecaria provides that no registration is made in the Land Registry of deeds transferring real estate unless “todos los números de identificación fiscal de los comparecientes” appear in them. Article 24 of the Ley del Notariado adds that the Notarial Council reports to the tax authority the transactions in which the tax number was not given to the notary. A deed without your NIE is, in law, a defective deed that the registry will not register.
3. Later dealings. Every later return you file as a non-resident owner, from the yearly imputed-income return to the sale, uses the same number. The non-resident tax guide shows where it comes in.

Who grants it and how to ask

The NIE is granted by the Dirección General de la Policía (national police). Article 205.3 says it is granted de oficio (automatically) for people applying for a residence document, but not for those linked to Spain by economic, professional or social interests, who must ask for it. Two conditions apply to these applicants:

• they must not be in Spain in an irregular situation;
• they must state the reasons why they request it.

Under article 205.4 you may apply in person to the police directly, or through foreigners’ offices or police stations. If you are not in Spain, you apply to the General Commissariat for Immigration and Borders through the Spanish consular offices abroad. Applying for a NIE from abroad walks through the consular route.

The same procedure applies to the certificates of resident and non-resident status (article 205.5).

The five-day term and silence

The procedure “habrá de ser resuelto en el plazo máximo de cinco días desde la entrada de la solicitud en el registro del órgano competente”. The decision must be notified within that period, “transcurrido el cual sin haber obtenido respuesta, se entenderá que la solicitud ha sido desestimada”. In plain words, silence means refusal, the opposite of tacit approval. A consulate states a longer practical time. The London page says a NIE “is normally issued within three weeks”, and the Montréal page says two weeks. Allow for that before the date of signature, and do not treat an absence of reply as an approval.

Mistakes to avoid

• Waiting for the notary’s appointment before asking. The consular route takes weeks.
• Using an old form of the regulation. The reference is article 205 of Real Decreto 1155/2024.
• Believing the NIE gives residence rights or exempts you from tax returns. It identifies you, nothing more.
• Confusing it with the número de identificación fiscal of a company, which has another format.

Which professional to consult

A lawyer registered with a Spanish bar association (colegio de abogados) can obtain a NIE for you with a power of attorney, where the consulate allows a representative. The notary who prepares the deed will ask for the number and will tell you if it is missing. See buying property in Spain as a foreigner for the whole sequence.
