Nickelodeon carried reruns of The Amanda Show during its TEENick block until September 5, 2007. On October 13, 2007, reruns started airing as part of the "TEENick on The N" block on The N. Reruns were pulled in March 2008 before airing again from April 4, 2009 to August 3, 2009. The series' original TV rating was TV-Y7, but was changed to TV-G, like all of the other shows that aired on the former TEENick block on Nickelodeon.

On 11 July 2011, the British Nicktoons channel began airing the series; it showed weekdays at 9:00 p.m. Some episodes missing from broadcast included three episodes (episodes 3, 8, 11 and 12) from Season 1, three Season 2 episodes (episodes 3, 7 and 14), and four episodes from Season 3 (episodes 1, 2, 6 and 10). Reasons for these episodes not being shown are unknown.

Nickelodeon Canada began airing the series on September 5, 2011, with the exception of Season 1 episodes 8 and 12 (which featured musical guests), and Season 3 episode 11. The series was removed from the schedule in 2012.

Reruns of The Amanda Show started airing on TeenNick on October 11, 2011. Although it was originally announced as part of TeenNick's 1990s block The '90s Are All That, the series instead aired as a standalone series during the daytime. The show was pulled in April 2012 following Bynes' arrest for a DUI. The show would later return on September 17, 2012, and aired in two-hour blocks, until being removed again on March 17, 2013. The series later premiered on The Splat (later NickSplat and NickRewind) on June 10, 2016, and on August 27, 2017, as part of a SNICK 25th anniversary marathon, before briefly returning again in 2020.
