Outsmarting Unknown & Unwanted Callers, Together

CallerSmart helps you investigate mystery phone numbers, and avoid unwanted calls and texts.

Find out who's calling or texting you

Have a missed call or text from an unknown phone number? We make it fast and easy to trace a number right from your smartphone.

Simply type the number into our free reverse phone lookup search bar. Then review information on who’s calling from where, alongside Trust Factor ratings and feedback from our user-driven community.

Be sure to add your own feedback to help protect other users, and earn an instant boost in Caller I.Q. points!

Stop unwanted calls and texts

Annoyed by a persistent telemarketer, prankster or Tinder date gone wrong? We’ll help you take back the privacy of your phone number.

Follow our step-by-step guides to block offending numbers permanently. Add your number to the National Do Not Call registry and easily file official complaints with the FTC.

To help protect other users against the same spammers and scammers, also leave useful feedback on untrustworthy phone numbers in the community phone book!

Join the fight and earn rewards

Your input helps drive our user community’s efforts against mystery and risky callers.

That’s why you’ll earn Caller I.Q. points towards rewards when you identify unknown callers and leave useful feedback following a reverse phone number lookup.

You’ll also unlock shareable Smart Badges, competing with other users to see how high you can climb in rank!
