This article is from the The Simpsons FAQ, by Ondre Lombard wakkojr@nospam.wcat.com and Andrew Gill superluser@mail.rit.edu with numerous contributions by others.
The numbers (7G06, 7F19, 9F08, 2F05, AABF01 etc.) refer to the production
code assigned by the production team. Each story has its own p-code which
refers to the season which it was produced for, but not necessarily the
one it was broadcast in. One or two episodes are usually held over for
broadcasting early the following season, hence 7F24 was the Season Three
opener. As a general rule of thumb:
7G codes refer to Season One episodes
7F codes refer to Season Two episodes
8F codes refer to Season Three episodes
9F codes refer to Season Four episodes
1F codes refer to Season Five episodes
2F codes refer to Season Six episodes
3F codes refer to Season Seven episodes
3G codes refer to special episodes commissioned during S7
4F codes refer to Season Eight episodes
5F codes refer to Season Nine episodes
AABF codes refer to Season Ten episodes
