What is a NIE number?
NIE stands for Número de Identidad de Extranjero – an identification number for foreign citizens in Spain. It is a necessary requirement when you buy property, open a bank account, or register with Spanish authorities. Your NIE number is unique to you and remains valid throughout your time in Spain.
Why do you need a NIE number?
If you plan to buy property on the Costa Blanca or anywhere else in Spain, a NIE number is mandatory. It is required for:
- Registering your purchase at the Land Registry (Registro de la Propiedad)
- Opening a Spanish bank account
- Paying property tax and other taxes
- Taking out insurance and service agreements
- Registering electricity and water at the property
How do you get a NIE number?
You apply for a NIE number at the Spanish police authority (Policía Nacional). As a Swedish citizen, you can often apply before traveling to Spain through the Spanish consulate in Sweden. You need to complete form EX-15 and present a valid passport. Many real estate agents and legal advisors can assist you with the process to save time and avoid mistakes.
Practical tips for the buying process
Make sure to obtain your NIE number early – ideally before you sign the purchase contract. This significantly speeds up the entire property purchase process. We also recommend that you engage a Spanish lawyer or legal advisor with experience handling Swedish buyers. They can guide you through all formal steps and ensure everything is handled correctly.
