UK: Ofcom launches investigation into whether Tismi failed to prevent misuse of its phone numbers by scammers
This investigation falls under an enforcement programme, launched earlier this year, looking specifically at phone and text scams. The aim of this Programme is to support best practice in relation to the use of phone numbers and to ensure that providers are following Ofcom’s rules.
LONDON, Oct. 20, 2024 — Ofcom has launched an investigation into communications provider Tismi, probing whether the company failed to take necessary steps to prevent the misuse of phone numbers allocated to it, including their use in scams.
Ofcom assigns large blocks of phone numbers to telecom firms like Tismi, which can then sub-allocate these numbers to other businesses or individuals. However, companies must ensure these numbers are not used for illegal activities, such as facilitating scam calls and texts.
Ofcom suspects Tismi may have violated its responsibilities by not conducting adequate due diligence to prevent such misuse. The investigation will assess Tismi’s compliance with several of Ofcom's rules.
Tismi’s case is part of Ofcom’s broader enforcement programme, which focuses on combating phone scams. Several providers, identified due to high levels of consumer complaints earlier this year, are under scrutiny. If Tismi is found to have broken the rules, Ofcom may impose sanctions and potentially open further investigations into other telecom providers.
Understanding Number Plan Misuse and Number Spoofing
The misuse of numbering plans is a significant concern in the telecom industry, especially with the rise of scam calls and texts. Criminals often exploit weaknesses in the number allocation system to perpetrate fraud. One common tactic is number spoofing, where scammers manipulate Caller ID information to make their calls appear as though they are coming from a trusted source, such as a bank or government agency. This makes it easier for them to deceive victims into sharing personal information or transferring money.
Ofcom has been cracking down on telecom firms to ensure they adhere to strict guidelines, including carrying out 'know your customer' checks to verify the legitimacy of their clients and monitoring any suspicious activity. This due diligence is critical in preventing scammers from obtaining phone numbers that they can misuse.
In recent years, the rise in voice over internet protocol (VoIP) technology has made it easier for scammers to spoof numbers, since it allows them to bypass traditional telecom infrastructures. To combat this, regulators like Ofcom have increased oversight on how telecom companies manage and monitor their number allocations, emphasizing the need for robust security measures to detect and prevent misuse.
Ofcom’s latest investigation signals a growing determination to enforce stricter compliance among telecom providers, aiming to reduce the growing menace of scams and protect consumers from falling victim to fraudulent activities.
