Illegal Robocalling Obligations for Voice Calls to/from United States Phone Numbers

Last Updated: September 28, 2021

Illegal Robocalling Traceback Cooperation

Twilio and Customer will cooperate with each other and third parties, as necessary, to determine the origin of a voice call to or from a United States phone number that is suspected of being an illegal robocall by identifying (a) the upstream voice service provider from which such voice call entered Twilio’s or Customer’s network or (b) its own customer or End User, as applicable, if such voice call originated from within Twilio’s or Customer’s network.

Robocalling Mitigation Database Registration

If Customer is considered a domestic or foreign voice service provider by the Federal Communications Commission (“FCC”), Customer is required to register with the FCC’s Robocall Mitigation Database. As mandated by the FCC, Twilio will block or otherwise not transmit Customer’s voice calls to or from a United States phone number if Customer is not registered in the FCC's Robocall Mitigation Database.
