You only need to have your personal tax number (CPR no.) issued once. The reason is that you will use the same personal tax number whenever you are in Denmark.
If you don’t have a personal tax number yet, we will generate it at the same time as we generate your digital tax card (skattekort). If you can't recall your personal tax number, we will find it for you when we generate your tax card.
Once we have generated your tax card, you can see your personal tax number (CPR no.) in your tax budget (forskudsopgørelse). We will send your personal tax number to your employer via Digital Post.
Your personal tax number is your unique ID number
It consists of 10 digits. The first 6 digits are your date of birth (day, month and year) while the last 4 digits are random. Example: 010185-1234
All Danish authorities, banks and employers use your personal tax number (CPR no.) to identify you.
