Country Specifics (Germany): Number Requirements


NOTE: From Wednesday 22nd May, we will be collecting the date of birth for end users of German numbers. In-use numbers that have already been activated will not be affected, unless you choose to reassign them.


What are the updated requirements when obtaining and using a German geographic number?

Applies To

  • Number Transfer
  • Geographic Numbers


A change to Section 112 of the Telecommunications Act (TKG) in Germany means that operators are required to share end-user details in accordance with the Federal Network Agency. Included in Section 111 of the TKG is the need for the birth dates of end-users.

Proof of address

8x8 is unable to accept utility bills as proof of address. The proofs need to be from official sources to prove that the end-user has a legal presence at the location within Germany. Documents issued by a local authority (a government agency) such as proof of residence from the municipality or proof of business registration from the trade registry are acceptable.

Here are examples of what is accepted:

For individuals:

  • A valid, German government-issued ID Card (18 or older) that shows the address
  • Meldebescheinigung (A valid Registration Certificate)

For businesses:

  • Handelsregisterauszug (Commercial Register)
  • Bescheinigung der Gewerbeanzeige (Business Registration)

Additional Information

This requirement applies to all German number types however it does not apply to business-registered end users. 

Furthermore, we will not be requesting validation of the date of birth via further documentation proof types.
