Spoofing, which is the falsification of telephone numbers, is a big problem having a negative impact on Belgian citizens and businesses. It facilitates phishing and other types of fraud.

The measure proposed in the draft decision submitted for consultation complements those already taken in the Royal Decree of 12 May 2024 to combat international voice calls with spoofed Belgian telephone numbers.

The purpose of this royal decree is to shut the door on spoofed calls made from abroad and received in Belgium. By means of the draft decision the extra possibility is created for organisations to put their telephone numbers which are not used for outbound calls, such as helplines, and which are sensitive to spoofing, on a blocking list.

Any originating national calls using a CLI that corresponds with the telephone numbers put on such a list, have to be blocked by operators. All interested parties, especially companies and authorities, interested in putting telephone numbers on such a list (called “DNOL” or Do Not Originate List) are invited to make this known and to react to the public consultation.
