Short codes enable your application to send SMS at 50 messages per second. Conversely, a long code can send 5 message per second. Thus, short codes are perfect for applications that need to send SMS messages to lots of users or need to send many time-sensitive messages. Additionally, based on the type of application you build and the messages you're sending, a short code may be the only type of number that can support your use case. Examples of applications that are best on a short code are: marketing communications, large-volume messaging, one-way notifications to users, and SMS marketing messages.
