A range holder is usually a network or wholesale provider that supplies numbers to other businesses. This Ofcom listing records an allocation only; it is not evidence about the range holder or caller. A number ported to another network still shows its original range holder here.

If a caller ID shows a GTT-EMEA LTD number and you did not expect the call, do not call back; contact the organisation you think it was on a number you find yourself.

What should I do after an unexpected call?

GTT-EMEA LTD is the range holder, not necessarily the organisation that called: numbers in its blocks are often used by its business customers.

Steps after an unexpected call
StepAction
1Do not call back a number you cannot identify. If it rang once and cut off, that is often a test that your line is live.
2If the caller said they were your bank, a company or the police, hang up and phone the organisation on a number you find yourself, or call 159 for your bank.
3Forward suspicious text messages to 7726, free of charge.
4If you lost money or shared details, contact your bank at once and report to Action Fraud (England, Wales and Northern Ireland) or Police Scotland.
5For unwanted marketing calls, report to the ICO and block the number on your phone.
6Calls to 01 and 02 numbers are charged at your provider’s standard landline rate (gov.uk/call-charges).
