Number portability in Germany follows strict rules and procedures that must be followed.
Number length:
The length of a number depends very much on the municipality of the number within Germany as well as whether there are extensions tied to the particular number(s).
Numbers in Berlin, Frankfurt, Hamburg, and Munich have a standard length of 10 digits (excluding leading 0)
Numbers in other municipalities have a standard length of 11 digits (excluding leading 0)
Extensions:
If the number(s) that you want to port is longer than 10/11 digits (depending on the municipality in which they are in) then you are using an extended version of that number which is typically a 10 block or 100 block of numbers. This is typically done on the main number which then allows for extensions of numbers in scenarios such as call centers, etc.
It is important to note that if you have an extra one or 2 digits you must check with the current operator to ensure that these numbers can be ported (10/100 block). You must also be assigned the whole 10/100 block. If not, the port of the standard number will be blocked.
It is important to note that only the standard number itself will be ported (not the extension of 10/100 numbers). The whole block extension will not be ported.
Example:
+49 (0) 40 123456781 - Hamburg
This number is 11 digits long (excluding leading 0/country code). The actual number itself is +49 (0) 40 12345678
+49 (0) 40 123456780 - 6789 are an extension of that number and not the physical number itself.

Contract type
In Germany, you cannot port your numbers until the end of your contract period with the current operator. If you have a future dated contract in place, you must first notify your carrier of your intent to porting your numbers away as well as any other subsequent actions (cancel access line, etc) before submitting your port to Telnyx. Please note that depending on the contract in place with your current operator, you may be charged early termination fees with them. If this is not done prior to submitting the port request to Telnyx then providing that the information on your port is accepted, the confirmed porting date will be the last day of your contract with your current provider.
Termination of connections
If there is a connection assigned to the DiD(s), you must ensure you have discussed the details of the port with the current provider prior to submitting a request with Telnyx. Once the DiD(s) port to Telnyx any remaining connection will be terminated.
If you are unsure of any of the above, please verify this with your current provider.
Once a port date has been confirmed with the current carrier, it is possible to change the date (this must be requested 5 Business days prior to the agreed port date). Please note that a date change after the request has been submitted with the current carrier comes with a fee of 50$ per order.
Porting out of Telnyx
