How does it work?

Reverse Phone lookup API is seamlessly linked to our global B2B database, housing over 350 million phone numbers from nearly all countries and territories. Here is how it works in 3 steps:

Phone number: Whether you receive an incoming call or provide a phone number, the API conducts a reverse phone number search.
Reverse phone number search: the API immediately initiates a reverse caller ID search, utilizing the provided phone number.
Caller Information: the API gives you caller details such as the name and country/region in less than 20 ms.

Highlights

Caller recognition before your phone rings (<20 ms)

Over 350 million phone numbers from 72 countries

3 sources of data: white pages, yellow pages and business pages.

Reverse Phone Lookup API is also recognized as a Caller ID API, which may be confusing for some. Both APIs provide reverse phone number lookup, which simply implies obtaining the name of the phone's owner and the location using the provided phone number.

If you would like to obtain more B2B data (not just the name and address of a caller) associated to the phone number, we suggest our Business Search API.
