Who called me from a Adepteo Limited number?

Adepteo Limited is a UK communications provider. That means Ofcom has allocated Adepteo Limited one or more blocks of UK telephone numbers under the National Telephone Numbering Plan, which Adepteo Limited can either use for its own customers or sub-allocate to resellers and downstream providers. In total, Adepteo Limited currently holds 366 allocated number blocks in our copy of the Ofcom plan.

Adepteo Limited's number ranges are concentrated in (028) (Northern Ireland), 0191 (Newcastle), 01434 (Hexham), 01539 (Kendal). Across all of its allocations the split is roughly 363 geographic landline, 1 03 non-geographic, 1 freephone, 1 premium-rate blocks. You can use the tables below to jump straight to a specific Adepteo Limited area code or number block and see the common call patterns reported for it.

The oldest Adepteo Limited number block in the Ofcom data was allocated in 2015, and the most recent in 2017. 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 Adepteo Limited 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 Adepteo Limited can sub-allocate or resell its numbers, the fact that a number sits in a Adepteo Limited block does not mean Adepteo Limited itself is calling you. Second, UK caller IDs can be spoofed: scammers can make a call appear to come from a Adepteo Limited 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 Adepteo Limited 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).
