Who is GTT-EMEA LTD?
GTT-EMEA LTD is the name Ofcom records as the range holder for 471 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 a mix of geographic landline ranges across 142 dialling codes and non-geographic 03/08/09 ranges.

What a call from a GTT-EMEA LTD range means
If our phone number checker shows GTT-EMEA LTD for a number, it means Ofcom allocated the block that number sits in to GTT-EMEA LTD. 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 GTT-EMEA LTD, 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 GTT-EMEA LTD 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.
