In their own words
Numverify
Numverify is a REST API for validating national and international phone numbers and returning results in JSON. It covers 232 countries, and a response can include validation status, local and international formats, country, location, carrier, and line type. Its numbering data is regularly updated and includes syntax rules and carrier, line type, and location information. Businesses may use validation to clean databases, reduce undelivered messages, and help prevent fraud. Developers can make URL requests and use standard REST calls to connect it to apps and CRMs; the site also describes a Zapier link to Google Forms. API connections use 256-bit HTTPS encryption, and the pricing FAQ says numbers are used only for validation and not stored or processed for other purposes. Usage can be tracked daily or monthly, with alerts near the allowance; overage fees apply beyond it. The free plan allows 100 monthly requests for non-commercial use. Paid plans start at $14.99 a month.
