Do we always use short codes for US 2FA and USSC?
- US Short Codes
- US Two-Factor Authentication (2FA)
- Outbound SMS
No, for Sprint and T-Mobile we use US long codes. The reason for this is to improve delivery.
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.
Customers using Dedicated Short Codes are not affected by these changes within the scope of 10 DLC.
