Toll-free SMS has several advantages over short codes: 

1. Support High-Volume use cases – Toll-free numbers have the ability to do the same throughput as short codes and support the same use cases.
2. Two-Way Communications – Engaging with your users is a high priority and toll-free numbers support this while short codes do not.
3. SMS Marketing – Toll-free numbers allow for SMS marketing campaigns.
4. Approval Time – Your toll-free number will be ready the same day you order while short codes can take weeks or months to be approved.
5. More Personal – Short codes number is oftentimes associated with auto-dialers, or SPAM messages, making those messages easy to ignore.
