Federal Student Aid assigns a number called a Federal School Code to each college that is qualified to disburse federal student aid. A Federal School Code is always six characters, beginning with 0 (zero), G, B, or E and ending with a five-digit number. For example, 003223 is the code for the University of Oregon.
If you want to apply for federal financial aid, you must enter at least one Federal School Code on your FAFSA. This code allows a school to access your FAFSA information in order to calculate your eligibility for federal financial aid.
