Detailed Report on Each Number
07418374634 — Parcel Delivery Scam
Nature of Scam: This mobile number has been widely reported for sending SMS messages claiming to be from popular delivery services like Royal Mail, Hermes, or DPD. The message usually states that a parcel could not be delivered and urges the recipient to click on a link to reschedule or pay a redelivery fee.
Why It’s Dangerous: The link in the message typically leads to a phishing website designed to collect personal and banking information. Victims have reported losing hundreds of pounds after entering their payment details.
Advice: Never click on suspicious links from unknown numbers. Official delivery services do not request payment this way.
02032686663 — HMRC Tax Scam
Nature of Scam: This number impersonates the HM Revenue and Customs (HMRC), claiming the recipient owes back taxes and will face arrest or legal action unless immediate payment is made.
Tactics Used:
- Automated calls demanding “urgent action”
- Live agents threatening legal consequences
- Requests for payment via gift cards or bank transfer
Why It’s Dangerous: This is a classic fear-based scam that preys on vulnerable individuals, especially the elderly or non-native English speakers.
Advice: HMRC never contacts people in this manner. Always contact HMRC directly via official channels if unsure.
0151 317 8500 — Aggressive Energy Sales
Nature of Spam: Reported for telemarketing energy deals, this Liverpool-based number aggressively targets individuals and small businesses offering “cheaper tariffs” or free energy audits.

02080906677 — Bank Fraud Impersonation
Nature of Scam: This number pretends to be from HSBC, Barclays, or Lloyds, claiming fraudulent activity has been detected on your account.
Modus Operandi:
- Requesting confirmation of account details
- Asking to move funds to a “safe account”
- Using technical jargon to sound credible
Why It’s Dangerous: These types of scams can lead to complete account draining. Victims have reported losing thousands in minutes.
Advice: No bank will ever ask you to transfer money over the phone. Hang up and call the bank directly using the number on your bank card.
