Shared Short Codes: The Problem & Solution

Megan Reninger by Megan Reninger

As part of AT&T’s new policies and code of conduct, no new short code programs will be activated or approved. The company also announced that all existing shared short codes will be terminated at a future date to be determined. Although the timeline is not yet clear when this will occur, AT&T has specified it would give “appropriate advanced notice” for these changes.

The company's decision was presumably motivated to improve SMS reliability and make better options available in 2019. The likelihood of other mobile carriers (Verizon, Sprint, T-Mobile, etc.) following a similar path is very high.


During the last two years, we launched a new texting platform that leverages business text messaging from local and toll-free numbers instead of our older shared short code of 292929.  The new platform features many product improvements and a better user interface. Today, 96% of our active customers are already enjoying tremendous value from using the new platform. As a result of AT&T’s decision, we have decided to end support for our old platform.

Moving forward, all new accounts created and customers that are currently using a shared short code will be assigned a Toll-Free Number. Customers can also contact us to text enable their local, landline numbers or toll-free numbers they own.
