Course Identification Numbering System (C-ID)

The Course Identification Numbering System (C-ID) is a statewide numbering system independent from the course numbers assigned by local California community colleges.  The purpose of a C-ID designation is to identify comparable courses within the California community college system.   When a C-ID number is listed in the catalog or schedule at the end of a MiraCosta course description, (example: C-ID AJ120) students can be assured that it will be accepted in lieu of a course bearing the same C-ID designation at another community college. Courses will be approved throughout the academic year for the C-ID designation.  The official C-ID webiste can be used to search for courses that have been designated with a C-ID number at a specific community college, including MiraCosta.

 Acceptance of C-ID

The California State Univeristy (CSU) accepts all courses approved for C-ID on the Associate Degrees for Transfer (AD-T). However, not all CSU campuses are accepting C-ID courses to satisfy specific major requirements after transfer. Students should always go to www.assist.org to confirm how each community college’s course will be accepted at a specific four-year college or university for transfer credit. The University of California (UC) does not participate in the C-ID  numbering system.
