In order to improve the security of Telnyx’s Messaging platform for end users, we have implemented two changes to Messaging Profiles:
Editing / Creating a Messaging or Verify Profile via the Portal and API will require users to configure whitelisted destination countries for outbound termination. Note that existing profiles will not be affected - only those that are newly edited or created.
When attempting to send to non-US destinations, Telnyx now requires a default Alphanumeric sender ID to be named on the Messaging Profile.

To learn about setting up Messaging Profiles, refer to this article.
You can configure a Alphanumeric Sender ID on the messaging profile via the Portal or API.
