Supported Short Code Carriers for SMS Notify!® API

Carrier coverage varies and is dependent on the number used to send text messages. Carrier networks may be accessed by long codes, short codes, or both. Long Codes are 10-digit SMS-enabled phone numbers used for low volume two-way messaging. Short codes are 5- or 6-digit numbers used for high volume SMS.

Coverage with U.S. Short Codes

These are some U.S. carriers that are supported on U.S. short codes. Any short code messages sent to an unsupported carrier will be sent over the long code network. Don't see your carrier? Contact Us to check if your preferred carrier is supported.
