Numverify vs Veriphone

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.

Veriphone validates phone numbers through an API or a web CSV workflow, returning validity, carrier, line type, and country information. The service says it supports 243 countries and territories and can format numbers as E.164, international, or local. Validation checks whether a number follows its country’s official numbering plan; it does not confirm that the phone is currently switched on. The instant API uses a GET request and returns JSON, while CSV uploads can be downloaded with results for each row. Current Carrier Lookup consults national portability registries and can return original carrier, current carrier, and ported status; a resolved lookup costs 10 credits. Standard validation costs 1 credit. The Free plan is free and includes 1,000 credits each month. One-time packages range from $24, paid once for 10,000 credits to $999, paid once for 5,000,000 credits; purchased credits do not expire. Veriphone also offers Zapier and Make integrations. API numbers are processed in memory, while infrastructure request URLs are retained for 30 days and CSV uploads remain until deleted or may be removed after 90 days.
