Vonage Customers Using US Shared Short Codes
T-Mobile and AT&T’s new Code of Conduct prohibits the use of shared originators, therefore, Shared Short Codes will no longer be an acceptable format for A2P messaging.
- Vonage customers using a Shared Short Code must migrate SMS traffic to either a 10 DLC, Toll Free SMS Number, or Dedicated Short Code.
- Vonage customers using our Shared Short Code API must migrate to either our SMS API or Verify API.
- Customers using Dedicated Short Codes are not affected by these changes within the scope of 10 DLC.
The US has very specific messaging restrictions and a direct connection is necessary in order to ensure message delivery to the numerous networks. Vonage has extremely high-quality, direct connections in order to facilitate delivery of your SMS to the US.
Sender ID
All SMS sent to the US must originate from either a US pre-approved long number, toll-free, 10 DLC, or short code that is associated with your Vonage account. Alpha Sender IDs are not supported.
Definitions
P2P: P2P (person-to-person) traffic may be sent using a Vonage US (or Canadian) long virtual number. If you do not already own one, long virtual numbers are available through your Vonage API account dashboard.
A2P: A2P (application-to-person) traffic, such as bulk notifications, should be sent to the US via Short Code (*Sprint and T-Mobile are heavily blocking Short Code traffic) or Toll Free Number.(**Vonage US Short Codes cannot be used to send SMS to Canada or other countries). If none of our pre-approved Short Code use-cases are appropriate, we can assist you in the application process for a dedicated Short Code.
Specific Features and Restrictions for Each Type of Number
- US LVN Long Virtual Number - Local Area Code Numbers
- US 10 DLC 10 Digit Long Code
- US Short Codes 5-6 digit numbers used only for SMS & MMS
