CRN is an acronym for Course Reference Number. It is the number that identifies a specific section of a course being offered. For instance, COMM 1007, College English will have numerous Course Reference Numbers each one having its own days, times, room, and instructor assigned.
All CRN's (Course Reference Numbers) are 5 digits long. When you are seeking information about a course you are currently registered in or are considering registering in, it is useful to have the following information with you:
Course Code e.g. COMM 1007
Course Title e.g. College English
CRN e.g. 56547
For post-secondary courses the CRN appears on STU-VIEW on your timetable under the Course Code, or on your registration acknowledgement. For Continuing Education courses you will find it on the Course Description Page when you register, or on your registration acknowledgement.
