Personal identity number and coordination number

Identity numbers are used in many countries. In Sweden there are two types of identity numbers, personal identity numbers (personnummer) and coordination numbers (samordningsnummer), and they are very widely used in society.

When you come to Sweden to live and work, you can get a personal identity number if you will be staying in Sweden for at least one year. If you are going to live and work here but don’t meet the requirements for registering in the Swedish Population Register (folkbokföring), you will get a coordination number instead of a personal identity number when you are registered for taxes. You cannot request a coordination number yourself, rather it is done by the authority that you are in contact with.

It is common for both public authorities and other actors to ask for your personal identity number or coordination number, and you can use your identity number in your contacts with for example authorities, healthcare and banks.

Other instances when you will need your personal identity number or coordination number:

  • To register a car
  • To enter the municipality’s housing queue
  • To register children at pre-school or school
  • To register as a job-seeker at the Swedish Public Employment Service (Arbetsförmedlingen)
  • To study Swedish at the municipality’s Swedish for Immigrants course

In Sweden, many private individuals handle their contacts and matters with public authorities digitally. In connection with this, you need to be able to identify yourself with a Swedish e-ID. And to be able to get a Swedish e-ID, you must have a personal identity number (a coordination number will not work). There are several other services in society where the personal identity number is requested. For example when you:

  • Sign up for insurance
  • Start a phone contract
  • Rent a car
  • Collect bonus points in a store
  • Buy a gym membership
  • Buy things online

When were the personal identity number and coordination number introduced?

Personal identity numbers were introduced in 1947, as a system with your date of birth plus a three-digit birth number. In 1967 a change was made to include a control number as the last digit of the personal identity number. Coordination numbers were introduced in 2000.

You can find out more about personal identity numbers and coordination numbers at the Swedish Tax Agency (Skatteverket).
