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.
