About the 01375 dialling code
01375 is the UK geographic dialling code for Grays Thurrock, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Grays Thurrock area.
A full Grays Thurrock number is normally written as 01375 XXXXXX. You can dial the local part on its own from within the same area, or the full number from anywhere in the UK.
Because of UK number portability and internet calling, a 01375 number no longer guarantees the caller is physically in Grays Thurrock. Fraudsters also "spoof" local codes like 01375 so an unknown call looks like a nearby business or neighbour — so treat an unexpected call on what is actually said, not on the area code alone.

Is a call from 01375 safe?

The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01375 prefix so you are more likely to answer. Never share bank details, passwords or one-time security codes with an unexpected caller, even when the number looks local — hang up and call the organisation back on a number you have verified yourself.
