Welcome to C-ID.net, the website for the Course Identification Numbering System (C-ID).
C-ID is a supranumbering system being developed to ease the transfer and articulation burdens in California’s higher educational institutions. To learn more about C-ID, please visit our ABOUT US page. To access FAQs for faculty and articulation officers, please click here.
Currently, C-ID has 315 approved descriptors and 31 draft descriptors from over 31 different disciplines. To view C-ID’s finalized Descriptors, or to review Draft Descriptors, please visit the DESCRIPTORS page. Once there, you can select finalized descriptors from a drop-down menu. The Draft Descriptors Review and Comment Area can be accessed by clicking on the View Draft Descriptors link on the Descriptors page.
To access the CSU courses that have been identified by campuses as comparable to C-ID descriptors, use the COURSES tab or https://c-id.net/courses. You can search for courses by discipline or CSU campus.
