Before going into detail about how to apply for your Affiliation Number, make sure you understand what documents you really need to live, study or work legally in Spain. Therefore we recommend you start by reading the main article and follow the instructions there.
What is the Affiliation Number?
It is a unique and personal identification number that identifies the citizen in everything that has to do with Social Security. It is obtained only once in life. This number will be the one used by any company to register a person in the Spanish social security system once they start working for a company (non-European foreigners must also obtain the corresponding work authorization in advance) or if they start their own business.
The Social Security Number becomes an Affiliation Number at the moment in which the citizen begins a work activity that includes him / her in the Social Security System.
Where should I apply?
There are two ways:
- You can obtain it in person at the Social Security Administration, without prior appointment. In the Provincial Directorate of the Treasury of Social Security that corresponds to you according to your address in Spain. To see which one corresponds to you, click here.
