When you have the SMS messaging add-on, you can create and send SMS messages from Marketing Cloud Next. Before you can start sending, your business must request and register one or more codes. Short codes and long codes are the numbers associated with incoming and outgoing messages. The registration process can take several weeks, so make sure to plan ahead.
These requests include all the information that you must create the necessary opt-in, opt-out, and help keywords and meet legal requirements.
Long Codes
To set up an SMS channel requires requesting the code to send your SMS messages, including any brands or campaigns used as part of your sends. You can request a 10-digit long code in the United States.
10-digit long codes require an associated brand and campaign to send messages. You can’t port an existing 10-digit long code. To use a 10-digit long code in the United States, complete three requests.
Short Codes
In the United States and Canada, you can now procure short codes by using the self-service procurement process. It’s possible to request a new US or Canadian short code or port an existing short code into your account. US and Canadian short codes don’t require associated brands or campaigns.
You can register short codes with a Salesforce Services agreement or a Mobile Approved Partner.
