A private or hidden number is calling me: what it means and what to do
The screen shows "private number", "hidden" or "unknown" instead of the caller's phone number. It is one of the situations that breeds the most distrust: among the many reports from the NoCall community, calls with no visible identity come up often.
1. Who calls with a hidden number
- Legitimate — Some hospitals and clinics, company switchboards and other organisations that keep their numbers private.
- Suspicious — Scammers hiding their number so you cannot identify them, look them up or call back.
2. Should I answer?
If you are expecting a call (hospital, delivery, job interview), answer carefully. If you are not expecting anything, you can let it ring: anyone with something legitimate to tell you will leave a voicemail, send a text or reach you another way.
3. What never to do
- Never give personal or banking details, your BVN or SMS codes to a hidden number.
- Never follow urgent instructions ("make a transfer now", "install this app", "dial this code").
- Do not try to call back: with no visible number, there is nothing to verify.
4. Blocking hidden calls
On iPhone, use "Silence Unknown Callers"; on Android, use the spam filter in the Phone app. If you still get suspicious calls from visible numbers, look them up on NoCall and read our guides for suspicious calls.
Who can call me with a hidden number?
Some hospitals, companies with switchboards and other organisations call with hidden numbers for privacy. But scammers use it too, so that you cannot identify them or call back.
Can I find out who is calling from a hidden number?
Not directly: the number is not sent to your phone. If the call is genuine, the caller will leave a message or identify themselves. If hidden calls turn into threats or harassment, report them to your network and to the police. If your network does not resolve your complaint, the NCC consumer portal and its complaint procedure explain how to escalate it.
How do I block hidden-number calls?
Both iPhone and Android can silence or block calls from unknown or hidden numbers in the phone settings. You can also turn on NoCall's automatic filtering.
