Protecting consumers from harm is a priority for Ofcom and we are concerned about the problem of scams facilitated by calls and texts.

A common tactic used by scammers is to ‘spoof’ telephone numbers to make them appear to be from a trusted person or organisation, such as a bank. Where scam calls appear trustworthy, it means victims are more likely to share personal information or make a payment, which can lead to significant financial and emotional harm.

In February 2022, we consulted on proposals to strengthen our rules and guidance for providers to identify and block calls with ‘spoofed’ numbers. This statement sets out our final decisions on these changes.
