  • As we know so far, One was absent in two episodes (in the episode Building Blocks and The Way of the Rectangle)
  • Eight's mask is a pale magenta in this series; it was dark magenta in Series 2.
  • Numberblock Zero would debut in this season, but only appear in her debut episode.
    • Zero later appeared in Fifteen's Minute of Fame and On Your Head.
  • When the Numberblob was first seen, fans thought that Zero is red and round. This would be proven incorrect.
  • Eight's mask not only gets lighter, but his pupils get noticeably smaller.
    • The reason is unknown.
    • The DVD/Blu-ray release date is unknown, just like Seasons 1-4, but is confirmed to be releasing in September 2019. (List of DVD releases)
  • First four episodes have only Numberblocks 1-5 appear. On the fifth episode, Zero, only Numberblocks 1-3 appear, but the new character 0 appears which means there are four characters appear in the episode but it also has the lowest characters in the episode. Numberblocks 6-10 started to appear in the next 15 episodes, and 11-15 appeared in the last 10. This is similar to Series 5.
  • This series marks the debut of the long-awaited Numberblock Eleven.
  • The creation of the new Numberblocks doesn't involve [x + 1 = y], it is now [10 + x = y] for the first time.
    • Eleven may be the only episode where it's [x + 1 = y] instead of [10 + x = y], though.
    • The future Numberblocks (not the 10s) consists of the multiple of Ten's blocks with another Numberblock's blocks. (12 has 10 and 2's Blocks)
      • Twenty has orange borders with tan blocks.
    • This has been heavily ranted on by a thankfully small handful of fans.
  • This season and the next 2 has the biggest number of episode. (30 episodes)
  • 13 and 14 only appear in two episodes in this series. In onscreen, 11 also only appear in two episodes in the show (On Thirteen, 11 is offscreen but you can see her football). In this season, 12 is the most appear of the new five characters (11-15), She has appeared in 7 episodes, but not appeared in the episode before. Fifteen has not appeared in these episodes
    • This is possibly because this season focuses on multiplication and other advanced mathmatics. Eleven and Thirteen are primes, which may be the reason why they appear rarely.
    • On second note, it's unknown if there's going to be numberbonds episodes about them.
  • The only number through 11-15 to make a vertical arrangement is Twelve, also the only Numberblock through 11-15 to have there face on the top.
    • However, in that form, it kinda looks like Two but with extended red eyes.
  • On topic, the first five episodes of these season are under Red Level One, the next 15 are under Orange Level Two, and the last 10 are in Yellow Level Three. It would be inaccurate to say that the events of the first five episodes happened before the Numberblocks manages to go above Five; during Ten, One asks the purpose of Ten's zero.
  • This is the first series to be distributed by BBC Studios, this is because at first, Series 1 and 2 (officially) were distributed by BBC Worldwide, but on 1 April 2018, BBC Worldwide merged into BBC Studios.
