About the 01304 dialling code
01304 is the UK geographic dialling code for Dover, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Dover area.
A full Dover number is normally written as 01304 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 01304 number no longer guarantees the caller is physically in Dover. Fraudsters also "spoof" local codes like 01304 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.

Is a call from 01304 safe?
Most 01304 calls are ordinary local calls from Dover homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01304 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 01304 (Dover) number from outside the UK, drop the leading zero and dial +44 1304 followed by the local number.
