- A new “Telecommunications Fraud Charter” binds leading networks to introduce technology to block overseas scam call centres from spoofing UK numbers.
- The initiative seeks to improve traceability of fraudulent calls and incorporates partnerships with the regulator Ofcom and the government, recognising fraud as a national security issue.
What happened: UK telecom giants commit to end phone-number spoofing within a year
Six of the UK’s largest telecom companies — including BT/EE, Virgin Media O2, Vodafone/Three, Tesco Mobile, TalkTalk and Sky — have pledged to upgrade their networks and implement new security infrastructure to prevent so-called “number-spoofing” calls over the next 12 months. The agreement, known as the second Telecommunications Fraud Charter, has the support of industry body Comms Council UK (CCUK) and the government.
Under the charter, the firms will deploy technology that can detect when a call supposedly from a UK number is in fact originating abroad — a common tactic used by fraudsters to masquerade as banks or government departments. They will also work with Ofcom to establish enhanced call-tracing mechanisms so that the origin of suspicious calls can be identified more reliably.

Why it’s important
Phone-number spoofing has become one of the most persistent and damaging forms of financial fraud in the UK. Research by the Home Office indicates that many consumers answer a call simply because it appears to come from a trusted UK-based number — while three-quarters of people are reluctant to pick up calls from unknown international numbers.
By committing to industry-wide infrastructure upgrades, the telecom companies are signalling that fraud prevention is no longer a matter for isolated action but a systemic challenge requiring cross-sector collaboration. The charter aligns with earlier regulatory moves by Ofcom to tackle related issues — for example, a previous ban on leasing global titles that let criminals intercept calls or texts.
For consumers, the promise is clear: fewer misleading calls, reduced risk of impersonation scams and enhanced trust in what appears on their phone screen. For the telecoms and financial-services sectors, it provides a necessary foundation for building more resilient defences — just as fraudsters adopt ever-more sophisticated tools. The 12-month timeline also adds urgency, turning lofty commitments into a tangible test of delivery.
