Numverify
What Numverify is
Numverify is a REST API that validates national and international phone numbers and returns results in JSON. It supports numbers from 232 countries, with responses that can include validation status, local and international formats, country, location, carrier, and line type. Its checks use regularly updated international numbering plans and related syntax and carrier data. Businesses may use the results to clean contact databases, reduce undelivered messages, and help prevent fraud. Developers can connect through URL requests or standard REST calls, including to apps and CRMs; the site also describes a Zapier connection to Google Forms. The API supports 256-bit HTTPS encryption, and its FAQ says phone numbers are used only for validation. Users can monitor request totals and receive alerts as they approach their monthly allowance. The free plan allows 100 requests monthly for non-commercial use. Paid plans start at $14.99 a month, and overage fees apply after the monthly allowance is reached.
