About the 01305 dialling code
01305 is the UK geographic dialling code for Dorchester (Dorset), allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Dorchester (Dorset) area.
A full Dorchester (Dorset) number is normally written as 01305 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 01305 number no longer guarantees the caller is physically in Dorchester (Dorset). Fraudsters also "spoof" local codes like 01305 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 01305 safe?
Most 01305 calls are ordinary local calls from Dorchester (Dorset) homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01305 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 01305 (Dorchester (Dorset)) number from outside the UK, drop the leading zero and dial +44 1305 followed by the local number.

- Silence unknown callers. iPhone: Settings → Apps → Phone → Silence Unknown Callers. Android: open Phone → Settings → Caller ID & spam and turn on filtering. Unknown numbers go straight to voicemail.
- Turn on your network's free spam shield. EE, O2, Vodafone, Three, Sky and most providers offer free spam/scam-call screening in their app or account settings.
- Register with the Telephone Preference Service (TPS). It's free and legally obliges UK companies to stop unsolicited sales calls within 28 days.
- Use a dedicated call-blocker app if nuisance calls are persistent — these screen against live community spam databases and can auto-reject flagged callers before your phone even rings.
- Never engage to "opt out". Pressing a key to be removed only confirms your number is live and usually means more calls.
