Request a block on the transmission of your data stored in the Central Register for Foreigners Unfortunately this specification of service has not yet been completely translated.

If you are registered in the Central Register of Foreigners, you can request that your data not be disclosed under certain conditions.

If you are a foreigner living in Germany for more than 90 days, your personal data will be stored in a central register for foreigners. Public authorities can obtain information about you from this register.

Non-public agencies, authorities of other states and supranational or intergovernmental agencies can also receive data from the Central Register of Foreigners if the legal requirements are met.

You can apply for your personal data to be blocked if you believe that you or your relatives are in danger. The data will be blocked if:

  • your interests worthy of protection or those of another person may be affected by the transmission of the data, or
  • at the request of the witness protection service.

Blocked data are provided with a transmission block. They may only be transferred to non-public bodies, authorities of other states or intergovernmental bodies in exceptional cases (without your opinion).

If there is an overriding public interest, the block is also effective vis-à-vis public authorities. How long the block applies depends on the individual case.

  • proof of your identity
  • where appropriate, suitable evidence that you or another person may be put at risk by the transfer

Forms : can be obtained from your competent office

Online procedure possible: no

Written form required: yes

Personal appearance required: no


  • You can demonstrate in a concrete and comprehensible manner that your interests or the interests of another person worthy of protection may be affected by the transfer of your data.


The transfer of data despite an existing transfer block is permitted in individual cases if there is an overriding public interest in knowing the blocked data (for example, in order to prosecute criminal offences).
