FAQPage Schema
How do I validate phone numbers and check fraud risk before sending messages?

Phone number validation and fraud risk scoring are performed by querying the Twilio Lookup v2 API to fetch line type, caller name, and identity match data for pre-send risk assessment. This requires setting the TWILIO_ACCOUNT_SID and TWILIO_AUTH_TOKEN environment variables.

Can I detect SIM swap and SMS pumping risk for messaging campaigns?

SIM swap detection and SMS pumping risk scoring are supported to strengthen pre-send risk assessment for messaging campaigns, minimizing misdelivery and fraud while maintaining customer reach across supported regions.

Do I need the Twilio SDK to perform caller name and identity match lookups?

The Twilio SDK for Python or Node.js is required to perform caller name and identity match lookups, along with the Twilio Lookup v2 API and valid TWILIO_ACCOUNT_SID and TWILIO_AUTH_TOKEN credentials configured as environment variables.

What is phone number line-type intelligence used for during user onboarding?

Line-type intelligence determines whether a number is mobile, landline, or VoIP, enabling identity verification during onboarding and ensuring appropriate messaging or calling channels are selected across supported regions.

Does Twilio phone lookup work for both calling and messaging pre-send validation?

Twilio phone lookup supports pre-send validation for both messaging and calling by validating numbers and fetching line type intelligence to determine deliverability and reduce fraud risk before campaign execution.

What phone number fraud detection limitations should I anticipate with Twilio Lookup?

Phone number fraud risk scoring and identity match capabilities depend on data availability across supported regions, meaning lookup results may vary by geographic location and carrier coverage for SIM swap and caller name data.
