Your contact information is registered and updated in one place
Update your contact information in only one place:
The mobile telephone numbers and e-mail addresses of citizens are collected in the common contact register.
The advantage of a common contact register is that you as a citizen do not need to provide this information to all the different government entities you are in contact with.
You update your contact information yourself and only need to do this in one place.
You can choose to register either your e-mail address or mobile telephone number, or both.
The common contact register is used when you log in with the ID portal to various public services, such as when completing a tax return in Altinn, or when the state and local government need to notify you electronically of decisions or other important information. It is only the state and local government that can use this register.
The contact register may contain your mobile phone number and e-mail address, information about which digital mailbox you have chosen, your choice of language for electronic communication and any preferences you have regarding electronic communication.
