Phone number spoofing scams are rampant throughout the UK. Criminals have simply become skilled at faking their caller ID to make it appear as though a trusted organisation, bank, delivery service, or government office is calling.
The call appears totally legit and real on the victim’s phone, making them easily convinced to provide sensitive information or follow dangerous instructions. An understanding of how spoofing works, together with recognising its early warning signs, forms the best means of staying safe.
How Phone Number Spoofing Works and Why It’s Growing
Digital tools enable scammers to conceal their actual phone numbers and display fake-looking ones instead. That is how they appear to be local companies or from a government department, increasing the chances that anyone will pick up the call. That’s why you need to understand everything about the process, as shown in Moonlock, which is among the resources that detail how such techniques work and why spoofing continues to evolve, especially as criminals take advantage of cheap VoIP services and automated calling systems.
The increasing dependence on mobile communication has provided more avenues for attackers to trick users. As technology improves, spoofed calls become increasingly indistinguishable from legitimate ones; therefore, awareness and simple verification steps remain crucial.
Common Signs a Call Is Spoofed
Most VoIP spoofing follows clear patterns that facilitate its early detection. Noting these patterns helps you avoid providing any information or falling for an urgent request. These include:
- Sudden urgency. Scammers will always prompt you to act quickly, claiming that your accounts are at risk or that payments are overdue. This pressure does not give one time to think and analyse clearly.
- Asks for personal or banking details. No legitimate organisation has a policy of asking for such information through unsolicited calls, passwords, PINs, or complete bank details.
- Numbers mimicking others. Fraudsters frequently copy trusted numbers to appear credible. Even if a call displays a familiar caller ID, you should verify it using an official website or an independent contact number.
Scammers’ Most Frequent Tactics
The tactics below share three common factors: the urgency of the call, a seemingly legitimate caller ID, and, in most cases, some immediate action requested or information provided. Ofcom research shows that over three months, almost 45 million adults across the UK received suspicious communications by phone or text. Here is how to identify spoofed calls:
- Bank security calls. The scammer will claim to be from your bank’s fraud or security department. They use number spoofing so their call shows the same caller ID as your real bank, and they build up your trust in them.
- Fake delivery or parcel updates. This tactic targets the fear of missing a delivery or being charged for redistribution. They will claim to be a courier service or delivery firm, often in a very believable manner, then ask for your payment, card details, or access to your phone to “solve” the problem.
- HMRC/benefits threats. Calls claiming to be from HM Revenue & Customs often say you owe tax or that benefits have been misclaimed, pressuring you to pay immediately or face arrest.
- Tech-support impersonation. The scammer will claim to be from your device’s manufacturer, an antivirus firm, or simply “tech support.”
How to Protect Yourself from Spoofed Calls
To prevent phone spoofing, follow these steps:
- Verification. If a call feels suspicious, hang up and dial the organization using a trusted number from its official website. Do not return the call using the same caller ID, as it may also be a caller impersonation fraud.
- Call-blocking features. Most mobile networks offer free scam-filtering tools that identify and block suspicious numbers. Smartphones have built-in options for blocking unknown or repeated nuisance callers. Enabling these features reduces exposure to automated spoofed calls.
- Reporting routes. Action Fraud is the UK’s national reporting centre for cybercrime. You can report suspicious calls here and also forward scam texts to 7726, the free spam-reporting service.
What to Do If You’ve Already Responded to a Spoofed Call
If you have already responded to one of the robocall scams, here is what you should do:
- End the call, disconnect your device from any remote-access session, and note down any details the scammer requested.
- Change passwords for email, banking, and key online accounts. Enable two-factor authentication to add an extra layer of protection.
- Call your bank using the number on the back of your card to report possible fraud.
- Submit a report to Action Fraud to help investigators track ongoing scams.
