Social Security Number

social security number

A Social Security number (número de seguridad social) is necessary to be able to work or be self-employed in Spain. It is also a requirement for obtaining the health card, which allows you access to public health care. If you’re job hunting, it’s a good idea to have a social security number already assigned, so you don’t have to worry about it once you’re hired. Your social security number becomes a número de afiliació (affiliation number) when you start work.

Once you are assigned a número de seguridad social, you are connected to the Spanish social security system and have the same number for life. All your labor activity is attributed to you and can be checked by downloading a Vida laboral (“working life”) document.
