Numverify review
A low-cost API for validating national and international phone numbers.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Numverify is a REST API for validating national and international phone numbers. It accepts numbers through URL-based API requests and returns JSON data covering validity, country, location, carrier, and line type. The service supports 232 countries and is suited to businesses that want to improve lead quality, reduce undelivered messages, detect fraud, or verify numbers during registration and data entry. Its best fit is a team seeking a focused validation API rather than a broader phone-data workspace.
Pricing is straightforward across the published plans. The Free plan costs $0 per month or $0 per year and includes number validation, carrier detection, line type detection, and country and location detection. Basic costs $14.99 per month or $161.99 per year, adding 256-bit HTTPS encryption and standard support to those core capabilities. Professional costs $59.99 per month or $629.99 per year, with the same listed feature set. Enterprise is listed at $129.99 per month and includes the same highlighted capabilities as Basic and Professional. The category details specify a monthly lookup limit of 5,000.
Numverify’s platform fit is narrow and clear: it is API-only, with JSON API responses and URL-based requests at the center of the workflow. Its listed integrations with Zapier and Google Forms can connect validation to common automation and form processes, while usage statistics and quota notifications help teams monitor activity. The core data set is practical, combining real-time validation with carrier, line type, country, location, and reachability-related data. Choose Numverify when a focused, low-cost API meets your validation needs. Consider another option if you need a broader interface or a wider integration ecosystem.
