How to Spot a Spam Call

Spam calls are becoming increasingly sophisticated. Here are red flags to watch out for:

• Unsolicited Contact: You didn’t request a call, yet they say it’s urgent.
  
• Pressure Tactics: Demands for immediate payment or action.
  
• Requests for Personal Info: Especially sensitive data like bank details, passwords, or NI numbers.
  
• Caller ID Looks Legitimate: Scammers can spoof real numbers.
  
• Pre-recorded Messages: Automated messages prompting you to “press 1.”
  

What to Do If You Receive a Spam Call

1. Don’t Answer Unknown Numbers: Let them go to voicemail.
   
2. Don’t Share Personal Info: Even if the caller seems to know your name or address.
   
3. Hang Up Immediately: Especially if you’re pressured to act quickly.
   
4. Block the Number: Most smartphones let you block recent callers.
   
5. Report the Number:
   
   • To Ofcom (UK communications regulator)
     
   • To Action Fraud (National cybercrime and fraud reporting center)
     
   • Use reporting tools like WhoCalledMe, TrueCaller, or 1572 service
     

Tools to Protect Yourself

• Call Blocking Apps: Such as Hiya, TrueCaller, or your network’s built-in tools.
  
• Register with TPS (Telephone Preference Service): To opt out of unsolicited sales calls.
  
• Enable ‘Silence Unknown Callers’: On iPhone or similar features on Android.
  

Why Are Spam Calls Increasing?

In 2025, the combination of data breaches, AI-powered robocalls, and low-cost VoIP calling has led to an explosion in scam call activity. Scammers increasingly use software to dial thousands of numbers automatically, often trying multiple angles—from financial services to health surveys—to catch victims off guard.

Legal Action and Government Response

The UK government and telecoms industry have been stepping up:

• Phone companies must block known scam numbers.
  
• New Caller ID regulations are being proposed.
  
• Stricter fines for companies misusing customer data.
  

Despite this, enforcement is difficult, especially when the calls originate from overseas.

Conclusion

Spam calls are more than just a nuisance—they’re a serious threat to public safety and personal finances. The 11 numbers listed above are among the most reported and harmful in the UK as of 2025. Being aware of them can help you protect yourself and others from falling victim to phone scams.

Remember: stay vigilant, don’t trust unsolicited calls, and always verify before you act.
