3301740216 – Telemarketing and Scam
This number is frequently associated with telemarketing calls, but they often cross the line into spam territory. Many people have reported receiving calls from this number regarding “PPI claims” (Payment Protection Insurance) and insurance scams. The callers typically claim that the recipient is eligible for a large refund, but the goal is usually to gather personal details or charge a fee for services that are either non-existent or entirely unneeded.

People have also reported that the caller may try to pressure you into acting quickly, making false claims of limited-time offers.
How to Protect Yourself:
- If you are unsure about the legitimacy of the call, hang up and do some research.
- Never agree to pay money upfront for services such as claiming a refund.
- Block the number and report the incident to the ICO.
7874425213 – Fraudulent Call
This number is often used for fraudulent debt recovery services. The callers typically claim to represent debt recovery agencies or offer to help reduce debts. They often provide false assurances of debt reduction, asking for payment upfront. If you fall for this scam, you may lose money without ever receiving any legitimate assistance.

Many recipients report that the callers are persistent and can sometimes use aggressive tactics, which can make it difficult for individuals to distinguish between a legitimate service and a scam.
How to Protect Yourself:
- If you receive a call from this number, do not provide any personal information or make payments.
- Hang up and research the company or service before engaging further.
- If you’re contacted by any debt-related service, contact your bank directly for verification.

Another frequent offender, this number is typically linked to robocalls claiming to be from HMRC (Her Majesty’s Revenue and Customs). The callers often assert that the recipient owes taxes or has some legal matter that requires immediate attention. Scammers use this tactic to create a sense of urgency, asking for payment in order to avoid arrest or legal action.

While HMRC does occasionally contact individuals regarding tax matters, they would never ask for payment over the phone or via email. Reports have highlighted that this number is most commonly used for scam calls that request payment through unconventional methods like gift cards or wire transfers.
How to Protect Yourself:
- Hang up immediately if you suspect that the call is a scam.
- HMRC will never ask for payment via unconventional methods. Always verify the legitimacy of any claims by contacting HMRC directly through official channels.

7418360549 – Scam and Fraudulent Call
This number is often linked to lottery or prize scam calls. Many recipients of these calls report being told that they have won a large sum of money, but to claim the prize, they must first pay a fee or provide sensitive information. The callers may even ask for your banking details under the pretense of transferring the prize money.
These types of scams prey on people’s excitement and naivety, convincing them that a windfall is just around the corner. In reality, the only thing you are likely to lose is your money and personal information.
How to Protect Yourself:
- If you did not enter a lottery or competition, it’s highly unlikely that you won anything.

This number is often reported in connection with robocalls that claim you have been selected to receive a government grant. The caller may state that you are eligible for a financial grant to help with expenses like home improvements, educational costs, or debt reduction. However, the catch is that they request payment or personal information before the “grant” can be processed.
These types of scams typically rely on the victim’s desperation or desire for financial assistance, making them especially harmful.
How to Protect Yourself:
- Government grants are never issued in such a manner. If you are contacted about a grant, verify it through official government channels.
- Do not share any personal information or make any payments in response to such calls.
- Report the call immediately to the ICO.

These robocalls often claim to offer low-interest loans and require applicants to provide personal and financial information to proceed. The scam may sound appealing, especially during times of financial hardship, but it is a trap to steal your information or ask for upfront fees.
Many victims of loan scams report receiving calls from numbers like this, promising easy access to large sums of money in exchange for minimal effort. Once personal information is given, scammers may either steal money or sell the details to other fraudsters.
