Finding the phone provider of a belgian number
The NPA maintains the CDRC for Number portability : https://www.crdc.be/.
Due to the portability right of users in application since around 2008, you can keep the same number while changing to a different telephonic operator (meaning the phone number prefix is no more a strong evidence of the telephonic provider for the phone number).
The CDRC does not provide information about :
- The activity of the phone number
- The owner of the phone number
