This review can result in the suspension of sending rights for a provisioned phone number or shortcodes; restriction of high-throughput access; suspension of provisioning rights for new phone numbers or short codes; and/or suspension of all network services.

What's the timeline?

AT&T have provided dates for the termination of Prohibited Campaigns running on shared codes (1/1/19) as well as dedicated codes (2/1/19). As for existing shared codes running clean traffic, they have noted that they will give ample notice of a termination date of 3 months prior to any termination and will likely coincide with the commercial availability of 10DLC.

What's Next for the businesses using shared shortcodes?

If your business is using a shared shortcode for high volume outbound messaging, we recommend you to switch to a dedicated shortcode, if your messages to AT&T in under 1000 messages a day, we will provide a 10DLC for your account automatically to avoid service disruption.

TXTImpact is also offering 6 months free Shortcode hosting service for all clients looking to switch to a dedicated shortcode. Please contact sales at 1-800-605-0280 to discuss your account.
