Switching operators and keeping your number


You can switch to another operator while keeping your fixed number (within the same telephone area) or mobile number.

This is called number portability.

What do you have to do to make use of this number portability?

You should arrange everything with your new provider and sign a “letter of authorisation”, showing that you want to keep the number. The letter of authorisation will enable your new provider to take the necessary steps with your previous operator.

An operator is not allowed to take the steps necessary to transfer your number unless he has a document signed by you; therefore an agreement made by telephone is not enough.

In most cases this service is free (by law, the operator receiving the new customer may charge up to € 10).

Do not forget to ask how you will be informed of the fact that you have become a customer of the new operator.
