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.
Twilio Lookup
Twilio Lookup is an API for formatting and validating phone numbers and enriching them with carrier and risk information. It can screen numbers before actions such as sending an OTP, creating an account, or processing a high-risk action. Available signals include line type and status, identity match, SIM swap detection, call forwarding, reassigned-number checks, caller name, and SMS pumping risk scoring. Lookup can also return active consent information alongside number details to help improve contact rates and message deliverability. Twilio provides API examples using helper libraries for Node.js, Python, C#, and Java, and lists Salesforce, Replit, and OpenAI as integrations. Twilio describes pairing Lookup with Verify to reduce fraud risk and improve OTP conversions. Lookup provides passive risk intelligence; it is not a standalone challenge-response authentication mechanism. Caller name is available only in the US, and call forwarding status only in the UK. Formatting and validation are free; other listed capabilities have per-request or per-query charges, while SIM swap and call-forwarding pricing is based on carrier access rates and enterprise agreements.
