Online - Change of address in the registration certificate part I (ZB I)

Due to nationwide regulations, the online portal for digital vehicle registrations (iKfz) had to be deactivated on January 1, 2024. The vehicle registration office does not currently offer online services. Work is currently underway to resume digital services. In the meantime, the analog services of the vehicle registration office are available to you. We apologize for the inconvenience.

If the main residence is in Bremen and the move is within the city, the change of your address must be notified to the vehicle registration authority by submitting the ZB I. The notification of the change of address is possible online since 01.10.2019. Here, the Bremen registration authority provides you with an online portal.


  • The applicant is a natural person
  • The change of the registration address must have been made in advance at the Citizen's Office
  • Payment of the fee by means of ePayment system

What documents do I need?

  • Registration certificate part I (ZB I) with attached security code
  • identity card (PA) / electronic residence permit (eAT) with activated online identification function or electronic proof of identity (eID card) for EU citizens and members of the European Economic Area

    To read the PA or eAT, an external card reader or an Android smartphone with version 5.0 or higher and NFC interface or an IPhone 7 or higher with version iOS 13.1 or higher and the badge App2 is required.
