If you mean “How can I find out who called from an unknown number?”, here are some simple and safe ways to check:
- Search the number online
- Copy the phone number and search it in a search engine. It may appear in business listings, scam-report sites, or public directories.
- Use a caller ID/reverse lookup service
- Apps and services such as caller ID tools can sometimes identify the caller or show whether others have reported the number as spam.
- Check your phone’s built-in spam protection
- Many Android phones and iPhones can warn you about suspected spam or unknown callers.
- Don’t call back immediately
- Some scam calls use “one-ring” tactics to get you to return the call. If the call seems suspicious, verify the number first.
- Check messages or voicemail
- Legitimate callers often leave a voicemail, text, or identifying information.
Be careful with websites that claim they can reveal private information about a caller—many are misleading or ask for unnecessary personal details.
