The CRN (Course Reference Number) is a five-digit number that identifies a specific section of a course. 

The first number in the CRN is the term for the course:

• 1 - summer
• 2 - fall
• 3 - winter
• 4 - spring

Course numbers are assigned during the process of section building, can be reused term by term, and are used to identify the content covered in a course. 

• Credit courses have a course number that includes letters and numbers (e.g. WR 121, ART 115).
• Pre-college credit courses have course numbers below 100, and do not transfer to a 4-year institution.
• Non-credit course numbers have letters and numbers in the format XART 5785. The "X" before the subject and the four-digit numbers identify the course as non-credit.

You may occasionally see a longer CRN number that includes a year and term code. The first four digits identify the year (i.e. 2022, 2023, 2024, ect) and the last two identify the specific term (i.e. 10 = Summer, 20 = Fall, 30 = Winter, 40 = Spring)

• 202410 = Summer of 2023
• 202420 = Fall of 2023
• 202430 = Winter of 2024
• 202440 = Spring of 2024

Example: 202320-21234 would be a course delivered in the Fall term of 2023. 202330-31234 would be a course delivered in the Winter term of 2024
