How do I set up a pre-approved Short Code Alerting Service?

Important Notice to 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 are not 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.
