If CPR (Danish national population register) had your data

  1. Look for CPR (Danish national population register)’s own notice or letter: it should say what of yours was involved. Keep it.
  2. An ID number cannot be changed, so lock it: a credit freeze or fraud alert in the US, a credit warning (kreditadvarsel) on borger.dk in Denmark, Cifas protective registration in the UK.
  3. Expect scams that use your details: calls, texts or emails pretending to be CPR (Danish national population register), your bank or the police. Never give codes or passwords, never approve a sign-in you did not start, never move money.

One email to confirm first. We use your address only for this alert, and one click deletes it.
