Everyone who applies for protection (asylum) or for a residence permit in Norway will be assigned a DUF number.
You will keep the same DUF number if you apply again.
The number has 12 digits and starts with the year when you applied for the first time (for example: 2012 586975 61).
You will find your DUF number on the case documents from the UDI. If you have a card for asylum seeker or a residence card, you will find your DUF number there as well.
