Where is the 01702 area code?

The 01702 dialling code is the UK geographic area code for Southend-on-Sea. Because 01702 is a geographic (01/02) code, a number using it is tied to the Southend-on-Sea dialling-code area — though with modern hosted telephony (VoIP) a business can keep a 01702 number after moving premises, so the code reflects the number’s designated area rather than a guaranteed physical location today.

Ofcom currently lists 622 number blocks under 01702, of which 349 are allocated to 80 communications providers.

Southend-on-Sea phone number format

A Southend-on-Sea number is made up of a 5-digit area code followed by a 5 or 6-digit local number. Written in full it looks like 01702 XXXXXX (the Xs stand for the local digits). Ofcom has not reserved a fictitious drama range for 01702; for on-screen examples it recommends the unused 01632 96000001632 960999 range.

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.

Call charges for 01702 numbers

Spotting spoofed 01702 scam calls

Fraudsters frequently spoof local dialling codes, faking the caller ID so a scam call appears to come from a Southend-on-Sea (01702) number you might trust. Remember:

  • A familiar 01702 area code is not proof the caller is local or genuine — caller ID can be faked.
  • Banks, HMRC and the police will never ask you to move money or share passwords or one-time codes over the phone.
  • If a call feels off, hang up, wait a moment, and call the organisation back on a number from their official website or your statement.
  • Report nuisance calls to the ICO and forward scam texts to 7726 (free).
