About the 01702 dialling code
01702 is the UK geographic dialling code for Southend-on-Sea, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Southend-on-Sea area.
A full Southend-on-Sea number is normally written as 01702 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 01702 number no longer guarantees the caller is physically in Southend-on-Sea. Fraudsters also "spoof" local codes like 01702 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 01702 safe?
Most 01702 calls are ordinary local calls from Southend-on-Sea homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01702 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.
To call a 01702 (Southend-on-Sea) number from outside the UK, drop the leading zero and dial +44 1702 followed by the local number.
