Where is the 01736 area code?

The 01736 dialling code is the UK geographic area code for Penzance. Because 01736 is a geographic (01/02) code, a number using it is tied to the Penzance dialling-code area — though with modern hosted telephony (VoIP) a business can keep a 01736 number after moving premises, so the code reflects the number’s designated area rather than a guaranteed physical location today.

Ofcom currently lists 388 number blocks under 01736, of which 144 are allocated to 99 communications providers.

Penzance phone number format

A Penzance 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 01736 XXXXXX (the Xs stand for the local digits). Ofcom has not reserved a fictitious drama range for 01736; for on-screen examples it recommends the unused 01632 96000001632 960999 range.

Who holds 01736 number ranges?

Ofcom allocates 01736 numbers to providers in blocks. These providers hold the largest allocations under 01736:

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.

Call charges for 01736 numbers

Calls to 01736 geographic numbers are charged at your phone provider’s standard UK landline rate and are normally included in inclusive call minutes.

Spotting spoofed 01736 scam calls

Fraudsters frequently spoof local dialling codes, faking the caller ID so a scam call appears to come from a Penzance (01736) number you might trust. Remember:

  • A familiar 01736 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).
