About the 01736 dialling code
01736 is the UK geographic dialling code for Penzance, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Penzance area.
A full Penzance number is normally written as 01736 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 01736 number no longer guarantees the caller is physically in Penzance. Fraudsters also "spoof" local codes like 01736 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.

History of the 01736 code
The code was 0736 until PhONEday, 16 April 1995, when a "1" was inserted after the leading zero to create 01736.
In the letter-dialling era the code had the mnemonic PE6 — on an old rotary dial, the letters PE (from Penzance) sat on the same holes as the digits 736, so subscribers literally dialled the start of the town's name.

Is a call from 01736 safe?
Most 01736 calls are ordinary local calls from Penzance homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01736 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 01736 (Penzance) number from outside the UK, drop the leading zero and dial +44 1736 followed by the local number.
