Why does caller ID show a name for unknown numbers?
Answer
That name comes from the network's caller-name lookup, not from your phone. Carriers query a shared database of registered names for the calling number. The name shown is whatever the caller's carrier has registered, which is why it is sometimes wrong or misleading.
Before you start: stop right away if…
- A recognisable name on caller ID is not proof of who is calling. Callers can register misleading names, and numbers can be spoofed.
- Never give personal or payment details to someone because the display named a company you trust.
Follow these steps
Understand where the name comes from
The name is looked up by the network from the calling number, not stored on your phone.
You should see: You know the phone is not the source.
Treat the name as unverified
Do not rely on it to decide a call is genuine. Names can be registered inaccurately or deliberately misleadingly.
You should see: You judge calls on what is said, not the label.
Turn the feature off if unwanted
Contact your provider and ask to remove caller-name display if you would rather see only the number.
You should see: Only the number is shown.
Enable nuisance call screening
Ask the provider about call screening or blocking services, which flag or intercept suspected nuisance calls.
You should see: Suspicious calls are screened before they ring.
Correct your own listing
If your outgoing calls show a wrong name to others, ask your provider to update the registered name for your number.
You should see: Your number displays correctly to recipients.

Extra tips
What to look for: Whether the displayed name matches who actually calls. A mismatch is a strong signal the call is not what it claims.
Before you change anything: Note whether your provider charges for caller-name display, as it is a paid add-on with some carriers.
