Enabling Opt-Out Assist

Opt-Out Assist is generally available for 10-digit long code (10DLC) numbers and for US/Canada Short codes. The feature currently needs to be manually enabled for both of these number types.

Account types

For managed accounts, please contact your Account Manager to request that Opt-Out Assist be enabled.
For non-managed accounts, please contact Vonage support to request that Opt-Out Assist be enabled.

Number types

For 10DLC numbers, Opt-Out Assist is enabled per primary_account_id of the 10DLC brand, and impacts all campaigns associated with that brand.
For short code numbers, Opt-Out Assist is enabled on a per short code basis.

Note: for Toll-free numbers (TFN) in the USA, STOP messages and opt-out functionality are managed automatically at a network level, enforced by the US operators. There is no need to enable this service, and it cannot be disabled. You can find further details in this support article
