Personnummer for EU citizens: what it is and how registration works

The personnummer is the Swedish personal identity number, and several steps of a move connect to it. Here is what it is and how registration generally works, without any promise about your individual case.

What it is and when it's relevant. If you move to Sweden and plan to live here for one year or more, population registration with the Swedish Tax Agency (Skatteverket) may be relevant. When you are listed in the Swedish Population Register for the first time, Skatteverket assigns a personal identity number (personnummer). Whether and when you can be registered depends on your situation — Skatteverket decides. Verify the current requirements with Skatteverket.

It connects to your right of residence. According to the Swedish Migration Agency, EU/EEA citizens generally have the right to work, study, run a business or live in Sweden without a residence permit — this is known as right of residence. Staying longer than three months generally depends on your situation, such as working, studying or being able to support yourself. Requirements can change — verify your exact situation with Migrationsverket. According to Skatteverket, EU/EEA citizens who plan to live in Sweden for one year or more are generally required to register, based on either their own right of residence (working, studying or being self-sufficient) or a residence permit as a family member.

If you're starting a job. According to Skatteverket, new arrivals starting employment in Sweden are generally assigned either a personnummer (if population-registered) or a coordination number (if not), and this identity number is generally used for tax registration and payroll. Exact steps and timing depend on your situation — verify directly with Skatteverket.

Nordic citizens. If you are a citizen of Denmark, Finland, Norway or Iceland and plan to live in Sweden for one year or more, you are generally required to be registered in the Swedish Population Register — Skatteverket decides whether the requirements are met. According to Skatteverket, you notify your move (e-service) and visit a state service centre in person for an identity check. The documentation Skatteverket lists for Nordic citizens covers identity, address, reason for moving and family relations — proof of right of residence is not among the listed requirements. Requirements can change — verify your exact situation with Skatteverket.

What no one can tell you in advance. No service can tell you in advance whether or when you will be registered — Skatteverket decides, based on your situation, and processing times vary. What you can do is prepare thoroughly and check the current requirements with Skatteverket before you act.
