Add Numbers to Powerpack

​

Long Codes

• Requires 10DLC registration for optimal throughput
• Recommended: < 200 messages/day per number

​

Toll-Free Numbers

• Higher throughput (25 MPS)
• Best for 2FA, notifications

​

Short Codes

• One US short code per Powerpack
• One Canada short code per Powerpack
• Same short code cannot be in multiple Powerpacks

​

Short Code Priority

​

Enable Priority

• Powerpack uses short code as source number
• Falls back to long codes if short code is unavailable

​

Disable Priority

• Powerpack uses long codes for outbound
• Short code only used for specific scenarios

​

Why Long Codes May Be Used

• Short code throughput exceeded
• Network compatibility issues
• Carrier-specific routing
