Overview
Short codes are abbreviated phone numbers (typically 4-6 digits) designed for high-volume SMS messaging. They offer higher throughput rates than long numbers, better deliverability, and are pre-approved by carriers for commercial messaging.
Advantages
Higher message throughput: send hundreds of messages per second. Better deliverability: carrier-whitelisted, lower filtering rates. Memorable numbers: easy for customers to remember and text. Two-way capable: receive replies on the same short code.
Use Cases
Marketing campaigns with high volume opt-in lists. Two-factor authentication (2FA) and OTP delivery. Voting, polling, and interactive campaigns. Customer engagement programs with keyword triggers.
