I believe it is case by case. I think only the Doctor and Romana currently have pages for multiple incarnations (plus a the Doctor and Romana overview page). I know that the Master was merged into a single page around 2012, and I don't know if that was the reason, but the Master's only real numbering was that Pratt and Beevers (and Delgado, according to Legacy of the Daleks) were number thirteen.
