Numverify is a REST API that validates national and international phone numbers and returns results in JSON.
What Numverify is
Numverify is a REST API that validates national and international phone numbers and returns results in JSON. It supports validation across 232 countries, using regularly updated numbering plans with syntax rules and carrier, line-type, and location data. Responses can include validation status, local and international formats, country, location, carrier, and line type. Businesses can use these checks when cleaning contact databases, reducing undelivered messages, or helping prevent fraud. Developers can make URL requests and connect it to apps or CRMs using standard REST calls; the site also describes a Zapier connection to Google Forms. API connections use 256-bit HTTPS encryption. The pricing FAQ says numbers are used only for validation, not stored or processed for another purpose. Usage can be tracked daily or monthly, with notifications as the allowance approaches; overage fees apply beyond the monthly quota, with alerts at 75%, 90%, and 100%. The free plan provides 100 requests per month for non-commercial use. Paid plans are Basic at $14.99 a month, Professional at $59.99 a month, and Enterprise at $129.99 a month. APILayer builds and maintains the product.
