Introduction: Why This Weekly Spam List Matters
Ever answered a call that made your heart race for all the wrong reasons? You’re not alone. Scam calls are becoming more sophisticated in the UK, often mimicking legitimate numbers or services. This guide is your weekly weapon against those tactics—an up-to-date UK spam numbers list showing the scam numbers this week UK residents are reporting the most.
We gather data from spam call tracking services, user submissions, and real-time threat intelligence to bring you the top 10 spam numbers doing the rounds this week.
1. 020 7946 0321 – The “HMRC Arrest Warrant” Scam
This number has taken the top spot for weeks, mainly due to its alarming message: you supposedly owe back taxes and face arrest unless you pay immediately.
📞 What They Say:
“This is Her Majesty’s Revenue and Customs. You have a tax debt. Failure to respond will result in legal action.”
🧠 Reality Check:
HMRC never makes arrest threats over the phone. They communicate via official letters and secure digital platforms.
🔐 Tip:
Hang up immediately and report to Action Fraud.
2. 07477 289451 – Fake Energy Rebate Caller
With rising energy costs, this scam preys on your hopes of saving money. The caller impersonates a well-known energy provider, offering a rebate in exchange for account details.
🎣 What’s the Bait?
They may say:
“You’re eligible for a £250 rebate. We just need to verify your bank account.”
👎 Truth Bomb:
Real companies never cold-call for rebates. If it sounds too good to be true, it is.
3. 0161 850 0091 – Fake Bank Security Team
This Manchester-based number pretends to be from your bank’s fraud team. You’ll be told that someone attempted a large transaction and asked to “confirm” your card details.
🛑 Why It’s Dangerous:
They collect just enough info to initiate real fraud. Several people have reported drained accounts within hours.
4. 020 3871 5244 – Amazon Refund Impersonator
You’ll receive a call or even a voicemail saying there’s an issue with a recent Amazon order.
🧾 The Pitch:
“There’s an unauthorized transaction on your Amazon account. Please verify it to process a refund.”
They’ll ask you to download software or click suspicious links.
🚨 Don’t Fall For It:
Amazon doesn’t call to verify orders unless you request it.
5. 07305 897632 – Delivery Text Scam
This number usually comes via SMS, claiming you missed a parcel. It includes a link to reschedule delivery—except the link is fake.
💳 Their Real Target?
Your credit card details. It mimics sites like Royal Mail or DPD to trick you.
✅ What You Can Do:
Always go to the official courier’s website and enter your tracking ID—never click unknown links.

6. 0131 357 1230 – National Insurance Number Fraud
This Edinburgh number claims your National Insurance number has been compromised and may be used in criminal activity.
🧠 Psychological Tactic:
It creates urgency and fear, tricking people into sharing their full name, date of birth, and NI number.
⚖️ Stay Safe:
If there really was a problem, the DWP would contact you by post.
7. 07512 004578 – Crypto Investment Trap
Ever seen flashy ads or influencers promoting crypto schemes? This number builds on that trend. They claim they can help you invest in Bitcoin or Ethereum.
🤑 What They Say:
“Join our VIP crypto club. You can double your investment in a week!”
🎯 Target Audience:
New investors, often students or retirees.
🧯 Warning:
They’ll ask for small deposits and then ghost you. There’s zero recovery.
8. 07700 900456 – Fake COVID Survey
This scam is relatively new but spreading quickly. The number contacts you claiming to be from NHS or Gov.uk, asking for feedback on vaccine rollout.
🦠 Real Motive:
They link to a “survey” that installs malware or phishing software.
🔎 Pro Tip:
NHS surveys are always linked to official NHS email addresses or sent via secure text systems.
9. 0800 123 4567 – Bank Account Lock Alert
This number appears to be toll-free and legit. That’s part of the trick. It claims to be from Barclays, NatWest, or Santander warning of suspicious logins.
📱 Classic Line:
“Your account has been frozen. We need to verify your security information.”
📛 Red Flag:
Legitimate banks will never call you asking for your PIN or full password.
10. 0845 672 1984 – Lottery Win Phishing Scam
We all love a surprise win… until it’s a trap. This number claims you’ve won a random lottery or competition—often one you never entered.
🎉 False Celebration:
“Congratulations! You’ve won £10,000! Just verify your bank details to claim.”
😤 Spoiler Alert:
This is one of the oldest scams still alive and well in the UK. They either steal your money or sell your data.
