Who called me?
Quick answer
In the UK, dial 1471 from a landline to hear the number of your last caller for free (if it wasn’t withheld). On a mobile, check your recent calls list. Don’t call back numbers you don’t recognize.
Free ways to find out
| Method | How it works | Cost |
|---|---|---|
| 1471 (UK landlines) | Tells you the last number that called | Free on most UK landlines |
| Recent calls list | Shows every number that called your mobile | Free |
| Built-in spam protection | Android and iPhone can flag “Suspected spam” or “Scam likely” | Free |
| Search the number online | Paste it into a search engine; others often report scam numbers | Free |
| Voicemail | Genuine callers usually leave a message | Free |
Many “who called me” websites ask you to pay for a full report. Free search results and your phone’s own tools are usually enough.
US tips
The US has no 1471 equivalent, but *69 works on some landlines to return or identify the last call (charges may apply). Carriers also offer free spam-blocking apps.
If the number was withheld
“No caller ID,” “Unknown” or “Private number” means the caller hid it. You can’t reveal it yourself. If you’re receiving harassing or threatening withheld calls, contact your phone provider and, if needed, the police.
Stop unwanted calls
- UK: Register free with the Telephone Preference Service (TPS) to reduce sales calls. Forward scam texts to 7726.
- US: Register with the National Do Not Call Registry and report scams to the FTC.
- Block the number on your phone.
Spot a scam call
Hang up if a caller pressures you, asks for passwords, PINs or bank codes, claims your account is compromised and asks you to move money, or asks you to install software. Your bank will never ask you to transfer money to a “safe account.”
