Einkennisstöfum

Einkennisstöfum, often translated as "personal identification numbers" or "social security numbers," are unique sequences of digits used in Iceland to identify individuals for various administrative and legal purposes. The system is managed by Registers Iceland (Þjóðskrá Íslands). Each Icelandic citizen and resident is assigned an einkennisstöfum at birth or upon registration.

The primary function of an einkennisstöfum is to streamline and secure administrative processes. It is used for a wide range of activities, including employment, healthcare, taxation, banking, and obtaining government services. This standardized identification system helps prevent fraud and ensures that individuals are correctly identified in official records.

The format of an einkennisstöfum is a ten-digit number, typically presented as DDMMYY-XXXX. The first six digits represent the individual's date of birth in the format day, month, and year. The last four digits are a serial number. It is important to note that while the date of birth forms the initial part, the einkennisstöfum is not solely based on the date of birth, as the serial number ensures uniqueness.

Access to and the use of einkennisstöfum are subject to strict privacy regulations in Iceland. Unauthorized disclosure or misuse of this information is illegal and carries penalties. The system is designed to protect personal data while facilitating essential governmental and societal functions.
