Submitting additional information for 10DLC


During use case registration, carriers request more information about the text messages you plan to send. Carriers want to know how your organization creates its texting lists and how texters would respond if someone asked for more details about your organization.


Help Message Response

This field is intended to show carriers a sample message identifying your organization to a contact if they need help identifying you. This message is encouraged to include a link to your organization's website so that a contact can independently verify who was texting them. For example:

NOTE - Help Message Responses must be between 20 and 320 characters.
