Social Security Number in Spain - Número de Afiliación Services

The Spanish Social Security Number (Número de Afiliación a la Seguridad Social) is fundamental identification for accessing Spain's comprehensive social protection system. Whether starting employment, accessing healthcare, or establishing long-term residence, Jobbatical provides expert guidance throughout the registration process—from eligibility assessment and document preparation to successful number assignment and benefit activation.

What Is a Spanish Social Security Number?

A Spanish Social Security Number (Número de Afiliación a la Seguridad Social) is unique identification assigned by Spain's Social Security Treasury (Tesorería General de la Seguridad Social) to individuals accessing the Spanish social protection system. Under Spanish Social Security Law (Ley General de la Seguridad Social), this number is mandatory for employment, healthcare access, and social benefit eligibility. The system covers healthcare (Sistema Nacional de Salud), unemployment benefits, pensions, family allowances, and occupational injury protection. The number format consists of 12 digits identifying the province, individual, and control digits, remaining valid throughout an individual's lifetime. Registration enables access to public healthcare, employment authorization verification, and social benefit accumulation. For comprehensive information, visit the Spanish Social Security Ministry or Seguridad Social official website.
