What is a CRN?


Each class offering of any course has its own unique identification number.

This is referred to as the CRN (or Course Reference Number). Typically, the CRN consists of 5 digits for Spring or Fall semesters and 4 digits for summer semesters.

For example, you might register for a fall section of an online Accounting 101 course which has a CRN of 20001.

.
HACC began offering online courses in the Spring of 1999. That semester 120 students enrolled in six courses. In the Fall of 2008, just 9 years later, HACC’s Virtual Campus enrolled 4,242 students from 35 PA counties and 11 states. These students could choose from over 120 different online courses!
