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 10DLC, 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 10DLC."
The USA has very specific messaging restrictions and a direct connection is necessary in order to ensure message delivery to the numerous networks. Nexmo has extremely high-quality, direct connections in order to facilitate delivery of your SMS to the USA.
Sender ID
All SMS sent to the US must originate from either a U.S. pre-approved long number, toll-free, 10 DLC or short code that is associated with your Nexmo account. Alpha sender IDs are not supported.
Definitions
P2P: Using Nexmo, p2p (person-to-person) traffic may be sent using a Nexmo US (or Canadian) long virtual number. Long virtual numbers are available here if you do not already own one.
A2P: A2P (application-to-person) traffic, such as bulk notifications, should be sent to the US via short code (*Note that Sprint and T-Mobile are heavily blocking Short Code traffic) or Toll Free Number.(**Note that Nexmo 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.
