What is the Common Course Numbering (CCN) System?

The California Community Colleges have implemented a Common Course Numbering (CCN) system to make transferring easier. These courses have the same number and content across all community colleges in the state. This means less confusion, better planning, and a smoother transfer process. These CCNs will be rolling out over the next few years.

Please note: You may start seeing the newest CCNs on audits as we prepare for the Fall 2026 schedule. If your audit looks incorrect, please reach out to a Counselor.

Four Elements of a Common Course Number

Course Type Identifier All CCN courses are indicated with a “C” prefix before the number
