TCPA Known Litigators Check is now available in Compliance Toolkit

The TCPA Known Litigators Check is now available within Compliance Toolkit to help safeguard your messaging by identifying and blocking messages to phone numbers believed to be associated with individuals or entities with a history of filing TCPA-related legal actions. 

This safeguard intelligently filters non-essential communications, such as marketing/promotional messages to phone numbers associated with known litigators, while allowing essential traffic, like transactional alerts, otp, and customer support messages, to reach the recipient. 

When a message is blocked by this feature, Twilio will return Error Code 30640.

Learn more about this feature and how to enable it in our documentation.
