DUF number

A DUF number is a twelve-digit number that is assigned to everyone who applies for residence in Norway.
  • The DUF number is the applicant's registration number in the UDI's computer system.
  • The number has 12 digits and starts with the year when you applied for the first time (for example: 2012 586975 61).
  • You will keep the same DUF number if you apply again.
  • You will find your DUF number on the case documents from the UDI. If you have a residence card, you will find your DUF number there as well.
