Kennitala (meaning “identification number”)[a] is a unique number given to every individual and company in Iceland so that they can be identified in databases and when doing business. It is used practically everywhere: When you go to the bank, when you go to the mechanic, and even when you rent a film. The number is not a secret, anyone can look up what your kennitala is.
If you spend a long time in Iceland, you need to apply for a kennitala.
A kennitala looks like this: 250592-3379. It encodes your date of birth, in this example the individual is born on 25 May 1992.
