0300 numbers are non-geographic numbers reserved for public bodies and not-for-profit organisations. Calls cost the same as calling an 01 or 02 landline number and count towards inclusive minutes on mobile and landline plans.

- Never read out one-time passcodes, card details or online banking passwords over the phone. Your bank and the police will never ask you to move money to a "safe account".
- Forward scam texts to 7726 for free and report fraud to Report Fraud, which replaced Action Fraud (in Scotland, to Police Scotland on 101).
