Who is TalkTalk Communications Limited?
TalkTalk Communications Limited is the name Ofcom records as the range holder for 3,939 UK number blocks. Ofcom publishes which communications provider each block of the national numbering plan was allocated to; it does not publish what those numbers are used for or who uses them, so everything on this page is the footprint, not the customer list.
Their allocation is overwhelmingly geographic landline ranges, spread across 596 of the UK’s 599 dialling codes — the allocation pattern of a national landline or VoIP provider rather than a local one.

What a call from a TalkTalk Communications Limited range means
If our phone number checker shows TalkTalk Communications Limited for a number, it means Ofcom allocated the block that number sits in to TalkTalk Communications Limited. That is genuinely useful — it tells you the number is a real, allocated UK number of a known type — but three caveats matter:
- It is not the caller. The person or business on the other end is a customer of TalkTalk Communications Limited, or of a reseller buying numbers wholesale from them.
- It may not even be their network any more. Numbers are ported between providers all the time, and Ofcom’s data keeps showing the original allocation.
- Caller ID can be faked. Spoofing lets a fraudster display any number, including one from a TalkTalk Communications Limited range they have nothing to do with.
Ofcom’s data shows the provider each number range was originally allocated to — not who holds an individual number today. Numbers are frequently moved (ported) between providers, and no public database reveals the person or business behind a specific number, so treat any service that claims to with suspicion.
