MitID, CPR and e-Boks: Denmark's digital services

Short answer

CPR is your personal identification number. MitID is your digital identity for signing in and approving actions. Digital Post is mail from public authorities. e-Boks is one platform for reading it and can also hold business correspondence. Udbetaling Danmark is a public authority, not an app or a bank.

Identify the task first

Registering your residence concerns your municipality and CPR rules. A login problem concerns MitID. A missing message concerns the mailbox or its sender.

Keeping these roles separate helps you contact the right service. Changing a login does not update your registered address, and changing a mailbox app does not alter an official decision.

CPR on arrival

Your municipality handles resident registration when you move to Denmark. You must actually have moved and meet the registration requirements. A personal number issued for tax administration does not itself establish resident registration.

If you already have a number, tell the authority. Follow the registration instructions rather than trying to create another identity.

Obtaining MitID

Official guidance describes two main routes: scanning a suitable passport with the app or obtaining help at citizen service, borgerservice. An in-person visit requires an appointment and the specified identification. Check the document list before attending.

Alternatives to the app include a code display and an audio code reader. Moving to a new phone requires activation or transfer; merely installing the app may not restore access.

Only approve actions you initiated and understand. Someone helping you read a letter does not need your personal login credentials.

Digital Post and e-Boks

Public-authority messages belong to one shared Digital Post mailbox. You can access it through borger.dk, the Digital Post app, e-Boks or mit.dk, with the required consent on private platforms.

Business correspondence is different: it follows the sender's platform arrangement. A business letter missing from borger.dk is therefore not necessarily lost.

Citizens normally receive Digital Post from age 15 and must read it. Exemption arrangements exist where digital reception is not possible. Ask the municipality about those arrangements instead of leaving important correspondence unread.

Understanding Udbetaling Danmark

This authority administers benefits including state pension, housing benefit, maternity benefits and family benefits. Guidance and self-service are provided through borger.dk.

Identify the benefit named in your letter and use its contact route. MitID provides access but does not automatically establish entitlement. Questions about a decision or payment belong with the responsible authority.
