Denmark Overhauls ID Rules Following CPR Data Leak

Danish authorities have updated personal identification rules after a massive CPR data leak. Civil registration numbers can no longer be used alone for identity verification. The change follows a cyber attack exposing personal data for millions of residents.

Residents and visitors in Denmark must now present secondary photo identification. Digital identification tools like MitID are also accepted for verification. This requirement applies to pharmacies, banks, and public administrative offices. Danish public authorities and financial institutions jointly announced the official overhaul.

Cross-border travelers in the Öresund region must prepare secondary official ID. Authorities implemented the rule to protect residents against further security threats.
