Receiving calls from private numbers can be unsettling, especially when the caller’s identity is concealed. In Kenya, such calls are often used for legitimate purposes, like customer service follow-ups.
However, they can be a useful tool for scammers and pranksters. Let’s break down what these calls are, why they happen, and what you can do to protect yourself.
What Is a “Private Number”?
A private number is when someone intentionally hides their caller ID. Instead of their phone number showing on your screen, your phone just displays “private number,” “unknown,” or “no caller ID.”
This is usually done using
- USSD codes like #31# before dialing your number.
- Phone settings that hide caller ID.
- Corporate lines or call centers that mask outbound numbers.
Why Would Someone Call Using a Private Number?
Callers may hide their number for both legitimate and shady reasons.
Legitimate Reasons:
- Banks or mobile service providers making outbound calls.
- Companies conducting surveys or interviews.
- Police or government agencies calling anonymously for security purposes.
Shady Reasons:
- Scammers trying to con you.
- People making threats or prank calls.
- Exes or stalkers avoiding detection.
Red Flags to Watch For
If you pick up a call from a private number and hear anything like this, it’s time to be extra careful:
- “We’re calling from Safaricom. Please confirm your M-PESA PIN so we can complete an update.”
- “You have unpaid KRA taxes. Settle the amount now via this Paybill, or you’ll face legal action.”
- “There’s an issue with your SIM registration. Share your ID number and PUK to avoid disconnection.”
- “Congratulations! You’ve won cash or a smartphone; just send airtime to claim.”
These are classic signs of social engineering scams designed to trick you into giving out sensitive personal and financial details. Legitimate companies will never ask for your PIN, PUK, or airtime over a call.
How to Stop Receiving Private Number Calls
Here’s what you can do depending on your phone and situation.
For Android Users

These features may vary slightly depending on your phone model.
Use Call-Blocking Apps
To boost your protection against unwanted or suspicious calls, consider installing trusted call-blocking apps.
Truecaller is one of the most popular options; it identifies unknown callers, blocks spam, and, in some cases, can reveal private numbers.
CallApp is another excellent choice, offering caller ID, call recording, and the ability to block hidden or private numbers.
Hiya provides real-time spam detection and can automatically block suspicious calls before they reach you. These apps are all available in Kenya and can be downloaded from both the Google Play Store and Apple App Store.
