Course ID's and Numbers

Page address:

Courses are often represented by two different values:

  • Course Number
  • Course ID

A course number is a three-digit value made by a department to represent a particular course within their department.

In a catalog, courses are represented by their course number. For example, MATH 122 could be a course offered by the Mathematics department.

For registration purposes, courses also have section numbers attached to them. Section numbers distinguish between multiple offerings of the same course within a term. For example, MATH 122 -02 could be a class offered by the Mathematics department in a particular term and MATH 122 -03 could be another class offered that same term.

Course numbers also indicate the level of a course.

  • 100 and 200 numbered courses are considered lower division courses
  • 300 and 400 numbered courses are considered upper division courses
  • 500 and 600 numbered courses are considered graduate level courses

Course ID's are quite different than course numbers.

A course ID is a four-digit number used to represent a course that can be enrolled in within the registration system for a given term.

Course ID's do not remain the same from term to term for any given course. These numbers are only used as an abbreviated way of referring to classes in a term for registration purposes. Course ID's are not the same a course numbers.

Both course numbers and course ID's show up in the Course Offerings and in the registration system. Course numbers are there because of the information they bring with them. Course ID's are there because these numbers are used to actually register for classes.
