Common Course Numbering (CCN) System

What is the Common Course Numbering (CCN) System?

The California Community Colleges are implementing a Common Course Numbering (CCN) system to make transferring easier! Under Assembly Bill 1111 (Berman), courses with the same content will have the same number across all community colleges in the state. This means less confusion, better planning, and a smoother transfer process! You will see the following CCNs in the Fall 2025 class schedule, with additional CCNs rolling out over the next few years.

Four Elements of a Common Course Number

Subject 4-letter standardized abbreviation to be used across the state
Course Type Identifier All CCN courses are indicated with a “C” prefix before the number
Number 4-digit standardized course number
Course Specialty Identifier System-level suffixes for special courses (H=Honors, E=Embedded Support)
