How do you recognize an unknown number calling you for free?

🔒 Just make sure to review privacy settings—some apps request access to your contacts.

6. Use VoIP Lookup Tools

If the call came from a VoIP (internet-based) number, tools like IPQualityScore can help verify if the number is linked to spam or fraud networks.

7. Watch for Red Flags

Even without tools, there are patterns that can help you recognize suspicious calls:

🚩 Short rings and hang-ups
🚩 Foreign or premium-rate numbers (+234, +44, etc.)
🚩 Numbers too similar to your own (a tactic called “neighbor spoofing”)
🚩 Calls at odd hours

What NOT to Do

⚠️ Don’t call back unfamiliar numbers, especially international ones—you could be charged high fees.

⚠️ Avoid giving out personal information to an unknown caller, no matter how convincing they sound.

⚠️ Don’t answer at all if you’re unsure—it can signal to robocallers that your number is active.

In Summary

You don’t need to stay in the dark when an unknown number rings your phone. By using free lookup tools, search engines, and caller ID apps, you can usually identify who’s calling—or at least rule out scams.

Next time your phone lights up with an unfamiliar number, take a moment, do a quick search, and decide if it’s worth picking up. It might just save you from a spammy headache.
