About the 01730 dialling code
01730 is the UK geographic dialling code for Petersfield, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Petersfield area.
A full Petersfield number is normally written as 01730 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 01730 number no longer guarantees the caller is physically in Petersfield. Fraudsters also "spoof" local codes like 01730 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 01730 code
The code was 0730 until PhONEday, 16 April 1995, when a "1" was inserted after the leading zero to create 01730.
In the letter-dialling era the code had the mnemonic PE0 — on an old rotary dial, the letters PE (from Petersfield) sat on the same holes as the digits 730, so subscribers literally dialled the start of the town's name.

Is a call from 01730 safe?
Most 01730 calls are ordinary local calls from Petersfield homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01730 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 01730 (Petersfield) number from outside the UK, drop the leading zero and dial +44 1730 followed by the local number.
