Use caller display to avoid scams. Use caller display to screen calls, but never trust the number alone.

Don't worry. Caller display is a useful tool, but it is not perfect. Knowing its limits helps you stay safer on the phone.

Quick answer

Use caller display to screen calls, but never trust the number alone. Scammers can fake display to look like 999, your bank, or a local number.

More detail

Caller display shows the number calling you before you answer. It helps you avoid unknown or withheld callers.

Criminals can spoof numbers so display shows a trusted name, 999, or a local code. Spoofing is illegal, but it still happens. That is why display alone cannot prove who is calling.

Combine caller display with calm habits: hang up on pressure, and call back on a number you find yourself.

Using display safely

Turn on caller display on your home phone if it has a screen.
Let unknown numbers ring out or go to voicemail.
If someone claims to be your bank or the police, hang up and call back on a known number.
Do not share passwords or PINs because display shows a familiar number or 999.
Tell family members that display can be faked, including emergency-looking numbers.
