Individual Phone Number Breakdown

1. 02037811093 — London Area

This number has been widely reported for impersonating banks or Amazon customer service. Victims mention receiving calls claiming that their account was compromised or that a large transaction was made. The caller often pressures the recipient to provide personal banking details or install remote access software.

Key red flags:

• Callers claim to be from fraud departments.
  
• Threaten immediate action or account suspension.
  
• Ask you to move money to a ‘safe account’.
  

 Tip: No bank will ask you to transfer funds to protect your account. Hang up and call your bank directly.

2. 01204565762 — Bolton

Frequent reports identify this number as a robocall claiming to be from HMRC or National Insurance. A robotic voice informs the user that there is a problem with their NI number or tax records and that legal action will be taken if they don’t respond.

Common script includes:

• “Your National Insurance number has been compromised.”
  
• “You are under legal investigation.”
  

 These are intimidation tactics used to exploit fear. Official bodies do not use robocalls for such sensitive matters.

3. 01224084745 — Aberdeen

This number is notorious for high-pressure sales tactics related to energy switching or false overbilling claims. The caller often claims to be from an energy provider or regulator and insists you’ve overpaid or are on the wrong tariff.

Scam details:

• They offer fake refunds or new contracts.
  
• Request meter readings or bank details.
  

 Be cautious of unsolicited calls offering savings or refunds without prior communication via mail or email.

4. 08006520266 — Toll-Free

Reported as a BT/Openreach scam, this toll-free number is used by callers who claim your internet is about to be disconnected due to suspicious activity. They guide you to download software or give them remote access to your PC or router.

Tech support scam traits:

• Claim they can fix “issues” with your Wi-Fi.
  
• Use technical jargon to sound legitimate.
  
• Ask you to install remote tools like AnyDesk or TeamViewer.
  

 Never grant remote access to someone who called you unexpectedly.

5. 01482 483281 — Hull

This number is linked to bogus insurance refund surveys, often under the pretense of reclaiming PPI or mis-sold insurance products. The callers request confirmation of personal data or bank details to “process your refund.”

Tactics used:

• Pretend to already have partial info about you.
  
• Push you to confirm or update missing details.
  

 This is a classic social engineering method. Do not give personal info unless you initiated contact.

6. 03316307363 — Non-Geographic

A newer entry into the scam ecosystem, this number is associated with fake broadband disconnection threats. Many people have reported a recorded message saying their broadband will be cut off due to suspicious activity.

Scam angle:

• Suggests illegal downloads or multiple IP logins.
  
• Transfers you to a “technician” for help.
  

 Broadband providers will always send written notice before action. Treat surprise calls with skepticism.

7. 02080589360 — London

This number has been connected with identity theft attempts, masquerading as fraud departments from high-street banks. Victims are told their identity has been stolen and asked to “secure” their accounts urgently.

Key behaviors:

• Urgent tone, pressuring immediate action.
  
• Requesting passwords, card numbers, or even video verification.
  

 Remember: Banks never ask for full passwords or PINs over the phone.

8. 07520619085 — Mobile SMS Scam

Although it originates from a mobile number, this scam mostly uses SMS messages. Common themes include fake package deliveries from Royal Mail, DPD, or Evri with malicious links.

Scam SMS examples:

• “Your parcel is awaiting delivery, please update your information.”
  
• “Click here to reschedule your missed delivery.”
  

 Clicking on these links can install malware or lead to phishing pages. Always verify parcel tracking via official apps or websites.

9. 03301740255 — Non-Geographic

This number is tied to a technical support scam, often involving a person claiming your computer has been compromised. They say your system is sending out viruses or being used illegally and offer to “fix it.”

Tactics:

• They may direct you to Event Viewer (normal Windows logs) to fake errors.
  
• Insist you pay for unnecessary software or subscriptions.
  

 Tech support should never initiate calls. Always hang up and check your system with trusted antivirus tools.

10. 01182286694 — Reading

Calls from this number often relate to fake loan offers or debt resolution schemes. Many people have been asked to provide upfront fees for a “guaranteed” loan, only to find the company disappears after payment.

Key traits:

• Too-good-to-be-true loan terms.
  
• Requests for payment via bank transfer or gift cards.
  

 Real lenders never ask for upfront payment for loans. Check the FCA register before dealing with any loan providers.
