The use of German National Numbers needs to comply with specific rules that you should be aware of.
Regulations
According to the German Telecommunications Act (TKG), any person using German National numbers for providing services (i.e. customer service) must state applicable charges up front. The maximum applicable charge is 0.09 euros per minute.
Additionally, German National numbers cannot be used as lines where the customer is put on hold while waiting for customer service. In other words, National numbers cannot be used for waiting loops.
To align with regulatory standards, please ensure that you meet the following conditions when using your German National numbers:
- ✅ Ensure information about maximum applicable charges is provided
- ❌ Do not use National numbers for waiting loops
- ✅ Use Toll Free, Local, or Mobile numbers when customers will be placed on hold while waiting for customer service
