    SMS Short Code Numbers for Marketing

    About SMS Short Code Numbers

    Applies to: All ONTRAPORT accounts.

    Have you ever noticed that SMS marketing from large companies usually comes from a special SMS number that is only five or six digits long? These special numbers are recognized for opt-in marketing purposes by the carriers such as AT&T, BT and Telstra. They are used for high volume SMS messages.

    The long digit numbers provided by ONTRAPORT look like normal phone numbers, and are intended for individual interactions between you and individual Contacts. Examples of this interaction include appointment reminders, birthday greetings, automated responses to their incoming texts, and messages to small Groups of Contacts such as advising your VIP members of an upcoming offer.

    If you plan to use SMS bulk marketing you should use a short code number instead of a conventional number. The guidelines suggested by Twilio, our partner in providing SMS service, is any time you send 200 or identical messages per day, or 30 identical messages to the same carrier such AT&T, BT and Telstra in the same day, you should use a short code number.
