- BAA win-loss records are included, as the NBA claims the BAA's history as its own. For example, at NBA History online its table of one-line "NBA Season Recaps" begins 1946–47 without comment.

- The New Orleans Pelicans began play as the New Orleans Hornets in the 2002–03 NBA season, due to the original Charlotte Hornets (which began play in the 1988–89 NBA season) relocating to New Orleans. The city of Charlotte was then awarded the 30th NBA franchise, dubbed the Charlotte Bobcats, which began play in the 2004–05 NBA season. The New Orleans Hornets rebranded as the New Orleans Pelicans, with the 2013–14 NBA season being their first under the Pelicans name. The Bobcats then rebranded as the Charlotte Hornets, first playing under the Hornets name in 2014. This second incarnation of Charlotte Hornets retained statistics and records of the original Charlotte Hornets franchise which played from the 1988–89 NBA season to the 2001–02 NBA season—as well as the statistics and records accumulated while playing as the Bobcats—while the New Orleans Pelicans franchise was retroactively regarded as a 2002–03 season expansion franchise, maintaining the statistics and records accumulated from that season onwards.
