About Numverify
Numverify is a REST API that validates phone numbers globally. It returns carrier information, geographic location, and line type (mobile, landline, VoIP) for any number you submit.
What it does
Send a phone number to Numverify's API, and it checks against telecom databases to confirm validity, identify the carrier (e.g., AT&T, Vodafone), and determine the country and region. It also flags numbers that are invalid or disconnected.
Who it is for
Numverify is built for developers, e-commerce platforms, and marketing teams. Developers use it to validate user phone numbers on signup forms. E-commerce platforms reduce fraud by checking billing phone numbers. Marketing teams clean phone lists before SMS campaigns. It is not designed for high-volume enterprise use without custom pricing.
Real use cases
- Verify phone numbers during user registration to prevent fake accounts
