New local numbers can be added to any of our tariffs. A prerequisite for obtaining a telephone number from a specific local network is that you also live or operate your business in that local network. So there must always be a real address in this local network.
As a private individual, you may obtain a maximum of 10 telephone numbers; as a company, you may obtain up to 100 telephone numbers. If more than 100 numbers are required, a higher requirement must be registered and declared with the Federal Network Agency. If the additional demand is conclusive, you will receive a corresponding letter from the BNA, which will allow the purchase of a larger block.
