Short Code vs. 10DLC Long Code: Which Should You Use?

10DLC works for most use cases. Short codes are better for very high-volume sends.

The right number type depends on your messaging volume, use case, and budget.

10DLC Long Codes

Standard 10-digit numbers registered through the 10DLC framework. Best for most conversational messaging and automation use cases. Lower cost than short codes, with strong compliance when properly registered.

Short Codes

5 or 6-digit numbers with higher throughput. Best for very high-volume, time-sensitive sends such as promotional blasts or one-time passcodes. Higher cost and require a separate registration process.

How to choose:

  • Use 10DLC for most sales, marketing, and service automation needs
  • Use short codes when you need very high throughput or specific brand visibility at scale
