# SMS Delivery and Sender IDs

All outgoing SMS messages that start a new conversation (Activation Messages or
Lesson Body) will include a sender ID in order to comply with carrier
restrictions.

The Sender ID is required by carriers when starting a new conversation, or
sending a message after being the last to have sent a message already, as well
as in an Activation Message.

Requirements:

 * We will include the Client name at the start of every message sent to the
   learner for consistency.
   
   

 * The Sender ID for your organization can be set up and managed by an Admin in
   Settings > Organization. It will default to the first 30 characters of the
   Organization's name.
   
   
   
   

 * The max character count enforced in the UI open creation is 30 characters

 * Clicking the "use channel name as Sender ID" checkbox (in Organization
   Settings), will default to using SMS channel name instead when added to a
   schedule. This is recommended for customers where a Channel is always used to
   push out training via SMS to employees.
