Civil registry number
The Civil Registration System is a central register of personal data containing information about people who are residing in Denmark and/or paying tax in Denmark.
When a person arrives in Denmark in order to work it must be decided whether they should be nationally registered on the basis of residence or whether they should be allocated a civil registry number for the purpose of having tax affairs handled in Denmark.
Rules for the allocation of a civil registry number based on residence
To obtain a civil registry number you must meet the following conditions:
- Your stay in Denmark must last more than three months
Persons immigrating from other Nordic countries, whatever their nationality, nationals of an EU/EEA country or Switzerland (and their family members from three permitted countries) may be in the country for up to six months before having to notify immigration authorities of their arrival
- You have acquired a residence or a fixed place of abode in Denmark
- You can show proof of legal residence in Denmark (in terms of documentation, this means a valid residence permit)
Notification of your arrival must be made to your local municipality within five days after the conditions mentioned in sections 2 and 3 being met. Find contact information for the various Danish municipalities.
Rules concerning the allocation of a civil registry number for the purpose of having tax affairs handled in Denmark
If you work in Denmark but do not live here, and therefore are not nationally registered in Denmark on the grounds of relocation from abroad, you are allocated a civil registry number if according to the tax authorities, you need one for the purpose of having tax affairs handled in Denmark.
