US telecom carriers have acceptable use text messaging standards, which are used to evaluate applications from customers seeking to register their toll-free or local phone number for text messaging. The table below outlines the ineligible use cases which, if included in your toll-free or local phone number registration application, will result in carriers rejecting your application.

Once verification is complete, carriers can use content-based filtering to block messages that include prohibited content in an effort to protect recipients. As of January 1, 2024, many carriers are also issuing aggressive fines for sending messages with prohibited content, even if the message delivery is blocked.

All Grasshopper customers should review the messaging principles and best practices guide published by CTIA, a wireless industry association, and the list of ineligible use cases below to ensure you are not using language, terminology, or practices that may result in your registration or verification being rejected, or invertedly lead to blocked message or fines once you begin sending messages.
