Reverse phone checker

All Searches are Confidential

Because we know you want to be discreet, all reverse number lookup searches are completely confidential. You can perform as many searches on as many names and phone numbers as you want, and the people you learn about will never know that you searched for them - something not every phone number lookup service can promise. Get started today!

Know Who's Calling You

Are mysterious numbers calling you at weird times? You don’t have to tolerate creepy callers who hide behind anonymity. With Instant Checkmate’s reverse phone lookup service, you can find out who’s calling you. Our detailed reverse number lookup reports include the identity of the caller, the carrier name, latitude and longitude, and demographic data. Our extensive phone directory includes virtually every number in the U.S., and even some you can’t find in your local white pages, so you can uncover exactly who’s calling you.

Beyond a Reverse Phone Lookup

We offer so much more than just a simple reverse lookup tool for phone numbers. Once you discover who owns the number, for an additional fee you can learn more about the mysterious caller with an online background check. This is a detailed report that includes addresses, criminal information, social media profiles and much more data that you won’t find in a phone book. You’ll know who they are, where they live, and maybe even learn their criminal history.

Search As Many Times As You Want

Use our reverse directory whenever you want to learn more about a phone number. Did someone give you their cell phone number, but you forgot their name? Use our cell phone lookup to get their full name before you call. You can also use our background check service to learn personal information about almost anybody. Want to reconnect with someone from your past? Just run a background check and you might discover their current address. Do you have someone’s name but don’t know how to reach that person? Pulling a background report may reveal the person’s current phone number. Instant Checkmate members have complete and unrestricted access to our full database of personal information.
