0300 numbers are reserved by Ofcom for public sector bodies and not-for-profit organisations, so they are widely used by government departments and agencies, NHS services, local councils, police forces and charities. Organisations must qualify before they can use the 030 range. Calls to 0300 numbers cost the same as calls to an ordinary landline and are included in call bundles, which is why many public bodies moved to them from more expensive 0845 and 0870 numbers. An incoming call showing an 0300 number may be a genuine public service, but criminals impersonating HMRC, the DWP or the NHS sometimes spoof these numbers, so check before sharing details.
A call from an 0300 number claiming you owe tax, face arrest or must pay a fine immediately is a common scam pattern. Genuine bodies will not object if you hang up and call back through their official number.
Who called me from 0300?
The prefix tells you what kind of number it is (public sector and not-for-profit (0300)), but not who is behind it. Numbers can be ported between networks and caller ID can be spoofed, so a familiar code is no guarantee. Search the full number to see its current carrier, line type and whether other people have reported it.
