If you plan to live in Sweden for at least one year, you must report your move to Sweden and get listed in the Swedish Population Register. It is the Swedish Tax Agency that decides whether you meet the conditions for being listed in the Swedish Population Register. Being listed in the Swedish Population Register means that you are registered as a resident of Sweden. Once you are listed in the Swedish Population Register, you will receive a personal identity number.
