Find the FAFSA code -- a six digit numerical number used to identify higher-learning institutions -- for each school to which you plan to send your FAFSA application. You can locate a FAFSA school code by visiting the FAFSA web page.
Fill out a FAFSA application for the school year for which you wish to attend. You have the option of either filling it out online or on a paper application, which can be downloaded from the FAFSA main site, printed and mailed.
Fill in the fields under "school selection," if you're filling out the online application. This will also be step six of the paper application. Enter the codes for the institutions.
Complete the remainder of your FAFSA application. Submit it electronically or mail it in the preaddressed envelope included in your FAFSA packet.
