Important 10 DLC guidelines for US customers

10 DLC stands for 10 Digit Long Code. Major US carriers have announced their requirements for a new standard for application-to-person (A2P) messaging in the USA, which applies to all messaging over 10 digit geographic phone numbers, also know as 10 DLC. This new standard provides many benefits including supporting higher messaging speeds and better deliverability.

Customers using the Vonage SMS API to send traffic from a +1 Country Code 10 Digit Long Code into US networks will need to register a brand and campaign in order to get approval for sending messages.

Note: US numbers can no longer be shared across brands which include both geographic numbers and US Shared Short Codes.

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.
