Spain’s NIE number is the personal and unique tax identification number that is used to track all financial and legal activities in Spain. The Spanish number acts as a tax and identification number, and is used in all fiscal transactions that involve the Spanish tax office.

A NIE number is mandatory for all foreigners with financial, professional or social affairs in Spain, regardless of whether they are a resident or non-resident in Spain. Children also need a NIE number in order to, among other things, get social security.

European citizens typically need to apply for a NIE number after three months of residence in Spain, while non-EU citizens will typically receive their application along with their Spanish residency. Official residents in Spain will also typically need to register on el padron. Spain’s population register.

This guide explains what a NIE number is, the application process, where to find application forms, and finding the right contact number.

If you are planning come to in Spain, you will need a NIE or a TIE. The process of getting one, however, can be confusing and frustrating especially if it’s your first time doing it and you don’t speak any Spanish. In this detailed blog post, we will breakdown what a NIE/TIE is and how to get one.

A TIE (tarjeta de identidad de extranjero) is a card (see below) that has your picture, NIE number, address and where you work/study. If you are a non-EU citizen, you have to apply for a TIE. This process is much more complicated since you need to register yourself at the city hall (empadronarse) to receive your padrón. Once you have done that, you are required to get an appointment at an immigration office which can be a headache.

Depending on which police station you are willing to go to or which city you are in, the nearest appointment you can get might be up to a month later. We recommend applying for an appointment once you arrive to Spain.
