What is Social Security Number?

The social security Number identifies the spanish citizen in his relations with the Social Security Administration.

This identification number is mandatory for any citizen who is a beneficiary of pensions, subsidies or Social Security benefits.

It is also compulsory prior to affiliation or registration with any Social Security scheme.

It is also essential when applying for inclusion in the health system, unless you do so as a beneficiary of another holder’s number (a child in relation to a parent, for example).

Why social security number is important?

The Social Security Number is transformed into an Affiliation Number when the citizen starts a work activity that determines inclusion in the Social Security System.

Characteristics of affiliation:

  • It is mandatory for persons included in the system for the purposes of rights and obligations.
  • It is unique and general for all the regimes of the system.
  • It covers the entire life of the persons included in the system.
  • It is exclusive.
