Important Note

The information on this page pertains only to semester courses from fall 2003 through summer 2009. For courses from fall 2009 onward, see current course number system/leveling.

Every legacy semester course number at Northeastern University consists of three parts:

  • A two- or three-letter department code
  • A single-letter code, most commonly U to indicate an undergraduate course or G to indicate
    a graduate course
  • A three-digit number

For example, in the course number ECN U115, ECN is the department code (indicating the economics department), U indicates an
undergraduate course, and 115 is the three-digit number.

The single-letter code and three-digit number together indicate the course level.
