| Can Call Blocking Reduce Fraud and Scam Calls? Here’s the Truth |
Discover if call blocking can truly reduce fraud and scam calls. Learn how call-blocking apps, carrier protections, and smart habits can protect you from scammers.
Fraud and scam calls have become a global menace, with millions of people receiving suspicious phone calls every day. From fake loan offers and phishing attempts to lottery scams, fraudsters use calls to trick unsuspecting victims into revealing sensitive information or making financial payments. But with the rise of call blocking technology, many users are asking: Can call blocking truly reduce fraud and scam calls? Let’s break down the facts.
What Is Call Blocking?
Call blocking is a feature available on most smartphones, mobile networks, and third-party apps that prevents unwanted calls from reaching your device. This feature works by:
- Blocking known scam numbers (listed in national or carrier databases).
- Filtering suspicious numbers using AI-based detection.
- Allowing users to manually block numbers that repeatedly spam them.
Some call-blocking apps like Truecaller and Hiya also crowdsource scam numbers, meaning once a number is flagged by users, it’s automatically blocked for others.
Can Call Blocking Really Reduce Scam Calls?
The short answer: Yes, but only to an extent.
Here’s why:
Reduction in Repeated Scam Calls – Blocking a number prevents that particular scammer from calling you again.
Carrier-Level Protection – Mobile networks now use advanced systems to detect and block bulk scam calls before they even reach your phone.
AI & Machine Learning – Modern apps use AI to detect suspicious patterns, such as calls from overseas numbers or known robocallers.
Scammers Change Numbers Frequently – Fraudsters often use new or “spoofed” numbers to bypass blocking systems.
Not 100% Foolproof – Call blocking reduces scam calls significantly but does not eliminate them entirely.
Best Ways to Stay Protected Beyond Call Blocking
If you’re serious about reducing fraud and scam calls, here are extra steps you should take:
-
Use Trusted Call Blocking Apps – Download apps like Truecaller, Hiya, or Call Control.
-
Enable Carrier Call Protection – Many telecom providers (like MTN, Airtel, Glo, AT&T, Verizon, etc.) offer built-in spam call filters.
-
Avoid Answering Unknown Numbers – If the call is important, the caller will leave a voicemail or text.
-
Report Scam Numbers – Report fraud numbers to your carrier or regulatory authorities (like FCC in the U.S. or NCC in Nigeria).
-
Never Share Personal Information – Banks, government agencies, and legit companies will never ask for your PIN, BVN, or OTP over the phone.
Can Call Blocking Stop Scam Calls?
Call blocking is a powerful tool that significantly reduces fraud and scam calls, but it’s not a complete solution. Scammers are constantly evolving, which means you need a multi-layered defense strategy — combining call blocking apps, carrier protections, and personal vigilance.
At the end of the day, awareness is your strongest protection. Stay cautious, never share sensitive details over the phone, and always verify before you trust.
