The use of 10-digit phone numbers (long codes) for SMS and MMS messages is heavily regulated in the US and Canada. Long codes, however, remain the medium of choice for businesses seeking to engage with their customers via SMS. A long code is more familiar to customers, has a price advantage, and is easily procured. As a result, long codes are the natural choice for most use cases.

Powerpack makes message communication using long codes effective and reliable at scale. It is designed to meet your overall message throughput and volume requirements, regardless of the size of your business.

By automatically distributing your overall message traffic across a pool of source numbers, Powerpack keeps you compliant with the per-day and per-second throughput guidelines defined by the Cellular Telecommunications Industry Association (CTIA).
