7701407206 – HMRC/Tax Scam Call

The number 7701407206 is frequently reported as a fake HMRC (Her Majesty’s Revenue and Customs) scam. Victims describe receiving threatening voicemails claiming that they owe back taxes and will be arrested if they don’t respond immediately.

These calls are designed to induce panic. Scammers often use robotic voices and fake reference numbers to seem more credible. HMRC has confirmed it will never ask for payment via phone or threaten arrest.

Tip: If you receive a call from this number, hang up immediately and report it to Action Fraud.

2045029385 – Bank Fraud Alert Scam

This number is tied to a banking scam, often pretending to be from major UK banks like HSBC or Barclays. Callers from 2045029385 claim there’s suspicious activity on your account and push for immediate verification of your details.

Their goal? Stealing your personal and financial information. Victims report being asked for online banking credentials or one-time passcodes.

Tip: Banks will never ask for PINs or passwords over the phone. Always call your bank directly if you’re unsure.

2038597221 – Fake Investment Scheme

2038597221 is often associated with investment scams offering “once-in-a-lifetime” opportunities. These scammers claim to work for a brokerage or crypto investment firm, promising high returns on small investments.

In reality, these are get-rich-quick schemes with no legitimate backing. The scammers disappear once they’ve received funds.

Tip: Be skeptical of unsolicited investment offers. Always verify the legitimacy of any investment company through the FCA (Financial Conduct Authority).

2030055852 – Tech Support Fraud

The number 2030055852 poses as technical support, often claiming that your computer or Wi-Fi network has been hacked or infected with a virus.

The caller may request remote access to your device. Once granted, they can install malware, steal data, or even lock your device and demand a ransom.

Tip: Real tech support teams never cold-call customers. Don’t give remote access to anyone unless you initiated the support call.

1274054504 – PPI Refund Scam

Although PPI refunds are largely a thing of the past, 1274054504 still circulates with fraudulent offers of claiming unused refunds. These scammers ask for a “processing fee” or personal information to start the claim.

These are classic advance-fee scams, and many victims have reported losing small but accumulating amounts.

Tip: Never pay upfront for refund services. Legitimate financial services don’t work that way.

2080584107 – Amazon Prime Subscription Scam

Calls from 2080584107 typically mention an issue with your Amazon Prime subscription. The caller might say a payment failed or that your account is due to be renewed automatically unless you cancel.

These calls try to trick you into pressing buttons or talking to an “agent” who will then ask for payment info or remote access.

Tip: Always verify your Amazon subscription status directly via your official Amazon account—not through calls.

2030842639 – Energy Provider Switch Scam

2030842639 is a fake energy tariff offer line. The scammers claim to be from British Gas or EDF Energy and offer heavily discounted rates to entice users to switch plans.

Many times, the goal is to gather bank details or trick people into long-term contracts with hidden fees.

Tip: Legitimate energy providers don’t aggressively push offers over cold calls. Always request offers in writing.

3316309813 – International Lottery Scam

This number appears to be originating from outside the UK, and callers claim you’ve won a foreign lottery or inheritance—but there’s a catch: you need to pay a processing or customs fee first.

The number 3316309813 has been flagged multiple times for these types of advance-fee frauds.

Tip: You cannot win a lottery you never entered. Never send money to claim “prizes.”

1592214193 – Fake Car or Life Insurance Agent

Scammers calling from 1592214193 often pose as insurance agents offering “exclusive” car or life insurance policies at drastically reduced rates.

These are typically phishing scams designed to steal sensitive identity or banking information under the guise of setting up a policy.

Tip: Only buy insurance from trusted brokers or through official company websites.

2080582305 – Broadband Disconnection Scam

One of the most dangerous scams of 2025 so far is associated with 2080582305. The caller pretends to be from BT, Virgin Media, or another broadband provider, stating that your service will be disconnected due to suspicious activity.

They instruct you to install software or verify account details to “prevent service disruption.”

Tip: Hang up immediately. Contact your broadband provider through official channels to confirm the status of your account.

Block Numbers: Use your phone’s built-in block function or a third-party app to block known spam numbers.
Never Share Personal Info: If you didn’t initiate the call, never share your banking or personal information.
