Do US Short Codes work outside of the USA?

 

**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."

 

Question

  • Do U.S. short codes work outside of the USA?
  • Do your US short code API's work outside of the USA?
  • Do your US short code API's work in Canada?

Answer

Yes and no. U.S. short codes can only reach U.S. subscribers. However, Nexmo’s 2FA and Alerts pre-approved short code API's can reach both US and Canada mobile phone numbers since we can identify the destination number and change the sender ID as needed.
