Moving in together? Remember to report change of address
Should you move in with your boy-/girlfriend, it's nice that the mail is also following.
What's nicer than hanging up a door sign with yours and your boy-/girlfriend's name? Remember to mark your mailbox as well, so the postman knows that you both live there.
It is also important to report moving to both the National Population Register and Posten. Once done, just spread the happy message to friends and acquaintances.
To change your address you must log in with a regular BankID (chip or mobile) or one of the other options that come up.
