One of the most commonly reported spam numbers, 01743839873 is frequently associated with aggressive sales tactics. This number often calls individuals without prior consent, typically offering services like warranties, energy-saving products, or insurance schemes. The callers are known for using pressure tactics to convince people into making quick decisions.
Suggested Action: If you receive a call from this number, do not engage with the caller. It’s recommended to block the number and report it via TrueCaller or the UK’s TPS.
2. 01616601030 (Manchester, UK)
This number is linked to a series of robocalls designed to either promote products or ask for personal information. The automated voice on the other end claims that the recipient has won a prize, but they will need to provide sensitive information to claim it. These calls are often timed to catch individuals when they are least alert.
Suggested Action: Always be wary of unsolicited calls claiming prizes. If you suspect fraud, block this number and report it using tools like WhoCalledMe or the ICO (Information Commissioner’s Office).
3. 01289222041 (Edinburgh, UK)
Often marked as a survey scam, this number calls individuals claiming to be conducting research or asking for feedback in exchange for rewards or gift vouchers. However, the real intent behind these calls is to collect personal information, which can later be sold to third parties.

4. 01952446550 (Wigan, UK)
This number is notorious for PPI (Payment Protection Insurance) claims. While it may have been relevant in the past, many of these calls are now out of context and may involve scams. The caller may try to persuade individuals that they are entitled to compensation or services.
