What is a Reverse Phone Lookup?

Reverse phone lookups solve the mystery of who called you by finding the owner of a number including cellular, landline, or VOIP lines. All carriers in the US are well supported including AT&T, Verizon, T-Mobile, and Sprint.

Reverse number lookups also provide useful information to help verify the identity of a user's profile or online payment. Using this tool for a quick phone number search can reveal a phone number's owner, and also recently associated emails and addresses with the number.

How Do Phone Number Lookups Work?

Number lookups check the owner name directly with the carrier using a service known as Caller ID. A ping is sent to the carrier network with a CNAM lookup request to retrieve the subscriber's current name. If the carrier does not have a valid name associated with a subscriber, then IPQS will check our extensive record database of US & Canada consumers and businesses to find a matching name. Confidently look up phone numbers with data appending from reputable sources directly from public records and carrier subscriber information that provide an accurate reverse phone number lookup.

Reverse Phone Lookup API

Enhance your site's data with real-time identity verification based on a user's phone number. Integrate reverse phone lookup API using our easy to use JSON and XML API endpoints which imports our phone number reputation data into your site's business logic. The phone number reverse lookup API provides low-latency responses with international coverage, so you can verify user identity in any region.

Free CNAM Lookup

A caller name lookup also known as a CNAM lookup is the best way to perform a reverse number lookup to search the owner of any phone number. Once you enter in the number using the free tool above, a phone number search request is sent to the carrier which provides landline or cell service to the number. This service can also be used by uploading a contact list or using the CNAM lookup API service for bulk reverse phone lookups.
