IPQualityScore Phone Validation API vs Numverify

IPQualityScore Phone Validation API validates phone numbers and scores their reputation to help identify suspicious users and invalid information in real time. It checks syntax, active connection status, carrier, line type, porting, and disconnection status, and analyzes reputation and abusive-behavior history. Coverage includes countries, carriers, and line types such as mobile, landline, VOIP, toll-free, and virtual numbers; detection includes disposable, temporary SMS, and VOIP numbers. Reverse lookups can return a subscriber or business name, with the product page reporting around 90% hit rates for most US and Canadian numbers. Queries return JSON or XML, and users can upload lists through a dashboard for batch processing. Salesforce and HubSpot integrations are listed. The API documentation advises providing at least 10 digits or a valid country for best results with short numbers. The free plan includes 1,000 lookups per month; paid access starts at $99/mo, with volume-tiered rates and no monthly contracts. A free trial is also available. The product page says support is available seven days a week, with typical responses within a few minutes.

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.
