One obstacle is the fact ROC identification cards are currently written vertically, and if the rather lengthy Bunun names are to fit on them, the space for names must be either made horizontal or considerably enlarged. Yet no relevant agency has made a move to correct this problem.
比如以身分證的格式而言，布農的命名很長，勢必要改為橫寫或增大欄位，但是目前未見相關單位有所行動。
