(The reason why I haven't added the Numbertaker, the Problem Blob and Numberjack 0 to the fancast is because since the Numbertaker is silent, and the Problem Blob's only capable of unintelligible speech, I personally think that the original voice actors would stay if a real American dub of Numberjacks was made. Also, I do imagine the voice actor of Numberjack 1 voicing 0, like the original voice actor for both of them, which is why I don't think a fan casting for 0 is needed in my personal opinion. You can also cast the same British voice actors for the American dub if you think that their voices suits the character enough for the rare recycled-lines character role.)
Numberjacks are a group of anthropomorphic numbers: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Only four of them team up on a mission: Turqouise Five (a female who likes being a numberjack), Yellow Six (who is good with some tricks and jumps), Dark Blue Four (who is a smart one but not quite sure) and Pink Three (a younger one who is cheeky and funny). They go about their everyday lives inside their sofa until a call comes in from real-life child Agents, who report problems that need solving. One or two of the Numberjacks fly out on location to investigate. The Numberjacks have to work out how to put things right, and thwart the dastardly intentions of the five Meanies. After much fun, adventure and powerful thinking, the Numberjacks win the day – until next time
