You cannot pick the short code from which your messages come as our system utilizes a common-use short code to send out texts. You do have the option to rent one of our ten-digit numbers but texts can only be sent to one contact at a time. If using the Short Code to send group texts, however, we always recommend you put your business/organization’s name in the Company Name line so that it comes up at the top of the text and in (parenthesis), like a header.
