Decoding CRN in College: A Comprehensive Guide
Navigating the world of college course registration can be daunting, filled with unfamiliar terms and codes. One such code that students frequently encounter is the CRN. This article aims to demystify the meaning of CRN in the college context, providing a comprehensive guide to understanding its significance and related academic terminology.
What is a CRN?
CRN stands for Course Reference Number. It is a unique five-digit number assigned to each specific section of a course. Think of it as a specific identifier for a particular class meeting. The Class Number (CRN) or Course ID is specific to a particular course section.
Why is the CRN Important?
The CRN is crucial for the registration process. When registering for classes, students use this number to enroll in a specific course section. You can use this number when registering for classes by inputting the number into the box in the Class Search labeled “Class Nbr.” The CRN ensures that the student is enrolling in the correct course, at the right time, and with the intended instructor. You will also need this number if you are requesting a permission number from a professor or department. You can find the class number for a course you're currently enrolled in in your This Week's Schedule box in your BroncoDirect Student Center.
Understanding Related Course Information
To fully grasp the importance of the CRN, it's helpful to understand other related pieces of information about college courses.
Course Prefix and Number
The four-letter Course Prefix indicates the department or program offering the course. Most of the prefixes are easy to figure out: ECON is Economics, PSYC is Psychological Sciences, and so forth. The 3-digit course number following the prefix gives some information about where a course falls in that department's or program's curriculum. Courses at the 100 or 200 levels are usually introductory and have a broader scope. Courses at the 300 level are mid-level, likely to be narrower in scope, and might require a lower-level introductory class as a prerequisite. Courses at the 400 level are likely to be very focused and assume that you already have a good amount of knowledge in that academic area. In the example above, 241 indicates that Anthropology considers this an introductory course.

Course Title
The Short Course Title gives a brief identification of the course. Sometimes there's a longer Full Course Title that gives a better sense of the course.
Course Section
Occasionally a course is taught with more than one "section" or class, usually by different faculty and usually at different times. You'll want to keep track of both the course number and section number to make sure you're referring to the right class. A Course Section is an individual class offering for a course. Most classes have more than one section offered each term to allow more students to enroll in the course. Course sections may have different times, classrooms, or professors. The section number for a class can be found in the Section area of the Class Search results.
Class Capacity and Closed Courses
Class Capacity: A limit on the number of students that can enroll for the course. Closed Course: A course that has reached both the class capacity limit and the wait list capacity limit. You will either need to enroll in another section or obtain a Permission Number from the class instructor.
Course Attributes
Courses that are part of the COLL curriculum can be any prefix or course number. The COLL designation is carried by an attribute attached to the course listing. For example, the listing for CLCV 355 - The Roman Family carries attributes for COLL 200, the ALV requirement, and the domain elective CSI. A Course Attribute is a search criteria option in the Class Search under Additional Search Criteria.
Cross-Listing
Sometimes two or more courses have the same course number and are listed in more than one department or program. This is called cross-listing. For example, ENGL 204: The Study of Language is also listed as ANTH 220 and LING 220, with the same title. These are all the same course taught by the same professor.
