About Numverify

What is Numverify?

Numverify is a REST API that validates phone numbers globally. 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.

Problem it solves

Invalid phone numbers waste marketing budgets, enable fake signups, and increase fraud risk. Numverify helps developers, e-commerce platforms, and marketing teams ensure every number is real, reachable, and correctly formatted before use.

Who it is for

Numverify is built for developers integrating phone validation into signup forms, e-commerce platforms checking billing numbers for fraud, and marketing teams cleaning contact 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
  • Validate billing numbers for fraud detection in online checkout
  • Clean contact lists for SMS marketing to reduce bounce rates
  • Identify line type (mobile vs. landline) for targeted communications

Key features

  • Number validation — Checks if a phone number is valid, reachable, and formatted correctly
  • Carrier lookup — Returns the telecom carrier (e.g., AT&T, T-Mobile, Orange)
  • Location data — Provides country, region, and city for landline numbers
  • Line type detection — Identifies if the number is mobile, landline, VoIP, or toll-free
  • Batch processing — Validate multiple numbers in a single API call
  • HTTPS encryption — All requests are secured with 256-bit SSL encryption
  • Global coverage — Supports phone number validation for 232 countries
