About the 01733 dialling code
01733 is the UK geographic dialling code for Peterborough, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Peterborough area.
A full Peterborough number is normally written as 01733 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 01733 number no longer guarantees the caller is physically in Peterborough. Fraudsters also "spoof" local codes like 01733 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 01733 code
The code was 0733 until PhONEday, 16 April 1995, when a "1" was inserted after the leading zero to create 01733.
In the letter-dialling era the code had the mnemonic PE3 — on an old rotary dial, the letters PE (from Peterborough) sat on the same holes as the digits 733, so subscribers literally dialled the start of the town's name.

Is a call from 01733 safe?
Most 01733 calls are ordinary local calls from Peterborough homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01733 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 01733 (Peterborough) number from outside the UK, drop the leading zero and dial +44 1733 followed by the local number.
