Who called me? How to identify an unknown number
A practical, step-by-step way to work out who is behind an unknown number - what the area code does and doesn't tell you, and when to stop and block.
What 800, 833, 844, 855, 866, 877 and 888 numbers actually mean
The seven toll-free codes, why newer ones feel less trustworthy than they are, and why the prefix tells you nothing about who is calling.
People often ask
Is it free to find out who called me?
Public guides and illustrative examples are free to read. Running a search requires paid access. Plans include a usage allowance, and coverage depends on the available sources.
Where does the data come from?
Only from publicly available sources - public listings, business directories, social profiles, and community spam reports where the number appears. We never access carrier records, voicemail, or the contents of any call or text, and every detail links back to its source.
Is this legal?
Yes. DeepSearch only searches information that is already public on the open web. It is not a background-check or FCRA consumer report, so results can't be used for employment, credit, housing, insurance, or tenant decisions.
Can it tell me for certain that a call is a scam?
Not for certain. We surface public spam and scam reports tied to a number and the likely owner behind it, but we can't promise a number is safe or dangerous. Use it as one honest signal - with the sources shown - to decide whether to call back.
The number that called me isn't in your results. Why?
Some numbers have little or no public footprint, especially freshly spoofed or burner numbers. When that happens there may be little to show. DeepSearch is honest about what it finds and shows you the sources behind every result.
Will the person who called know I looked them up?
No. Your searches are private. DeepSearch only reads public information - looking a number up never calls it back, texts it, or notifies anyone.
