Ofcom's approach on Calling Line Identification and the prevention of spoofed numbers - Which? response

Which? welcomes the opportunity to provide our views on Ofcom’s proposed approach to CLI authentication and how it may work within the UK. In 2022, we supported Ofcom's proposals to improve the accuracy of Calling Line Identification data as part of their efforts to reduce the number of scam phone calls and the harm they caused consumers. We welcome further review by Ofcom concerning the implementation of CLI and other measures which may be sufficient in tackling number spoofing.
