What Is a Short Code?
Short codes are 5- to 6-digit numbers designed for high-volume business messaging. Unlike standard phone numbers, short codes are exclusively used for SMS and MMS and offer faster message throughput, improved deliverability, and compliance with carrier regulations.
What is a Dedicated Short Code?
A dedicated short code is exclusively assigned to a single business, ensuring full control over branding, messaging, and customer engagement. Dedicated short codes allow businesses to send mass notifications, authentication codes, and marketing campaigns at scale.
