Phone numbers that are recycled by telecom companies pose a significant risk to mobile phone users, according to a warning issued by Which?. The consumer group highlighted the dangers of reusing old numbers, which could lead to hacking, nuisance calls, or even having the phone line disconnected. Which? raised concerns about the practice of assigning new numbers that were previously used by other individuals, as there is a limited pool of 11-digit combinations available in the UK.
In a recent study conducted by Which?, over 15,000 members were surveyed, revealing that 11% of respondents had changed their mobile numbers in the past decade. However, only half of them had updated their new numbers across all relevant organisations and online accounts. Shockingly, 10% admitted to not updating their new numbers anywhere. This oversight could expose users to various risks, especially concerning the security of online identities and accounts.
The research conducted by Which? indicated that 7% of participants had encountered problems due to the deactivation or reassignment of a landline or mobile number. Issues ranged from receiving calls and messages intended for the previous owner to being harassed by debt collectors or individuals seeking to purchase illicit substances. Lisa Barber, the tech editor at Which?, expressed concern over the detrimental impact recycled phone numbers can have on both the previous and current owners.
Which? has called upon Ofcom to take action in improving communication between providers and customers regarding the potential deactivation of numbers. The consumer group emphasized the need for addressing the negative consequences associated with recycled numbers and ensuring the protection of consumers. With sensitive information often transmitted via text messages or used for online account verifications, the risk of unwanted access or misuse remains prevalent.
The warning from Which? serves as a cautionary reminder for mobile phone users to stay vigilant and update their contact information promptly. As the issue of recycled numbers continues to pose security threats and inconvenience, proactive measures are essential to safeguard personal data and prevent potential risks associated with outdated phone numbers.
