The oldest Belgacom International Carrier Services SA number block in the Ofcom data was allocated in 2016, and the most recent in 2021. Allocation dates matter because a number that has been live for many years is more likely to be a settled business or residential line, whereas a very recently-allocated block is more commonly seen in VoIP and virtual-number services — the kind sometimes used for short-lived marketing or scam campaigns.

Is a Belgacom International Carrier Services SA number safe to answer? In most cases, yes — the overwhelming majority of calls from any UK provider's range are ordinary, legitimate calls. However, two things are important to understand. First, because Belgacom International Carrier Services SA can sub-allocate or resell its numbers, the fact that a number sits in a Belgacom International Carrier Services SA block does not mean Belgacom International Carrier Services SA itself is calling you. Second, UK caller IDs can be spoofed: scammers can make a call appear to come from a Belgacom International Carrier Services SA number they don't control. So treat the number as a clue, not proof — judge the call on what the caller actually asks for.

If a Belgacom International Carrier Services SA number called you and you're unsure, don't share security details, bank information or one-time passcodes, and don't return the call until you've verified it independently. You can block the specific number on any UK smartphone from the recent-calls list, enable free network-level call screening through your own landline provider, and register with the Telephone Preference Service (TPS) to cut legitimate marketing calls. Persistent nuisance calls can be reported to Ofcom, and suspected scams to Action Fraud (or Police Scotland on 101).
