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

** 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 10DLCToll 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."****



To set up an alerting service you need to first request an alerts shared short code from the Nexmo Dashboard.

Input the the information about your campaign (all fields are required) and request your short code to be set up

Everything must be CTIA and TCPA compliant.
