In 2025, the UK continues to face a rising tide of scam and spam phone calls, with thousands of reports each month about nuisance calls, fraud attempts, and impersonation scams.

How Scammers Use Number Spoofing
One reason these numbers are so hard to trace is due to number spoofing, where scammers make the call appear as though it’s coming from a trusted UK number. They may even mimic your local area code. This tactic increases the likelihood of you answering and trusting the call.
Staying Safe: Tools and Apps You Can Use
To better protect yourself, consider using apps and services that filter or block known scam numbers:
- Truecaller (caller ID and spam blocking)
- Hiya
- Your mobile provider’s call protection service (e.g., Vodafone’s Secure Net, EE Call Protect)
Additionally, register your number with the Telephone Preference Service (TPS) to opt out of unsolicited sales and marketing calls.
Final Thoughts
Scam calls remain one of the most widespread digital threats facing UK citizens in 2025. With increasingly sophisticated tactics, it is essential to remain vigilant, informed, and proactive in reporting these threats.
Remember, legitimate organizations will never pressure you over the phone for sensitive information or urgent payments. When in doubt, hang up and verify independently.
