In the case of Taipei County, early estimates suggest that it will be divided into 12 electoral zones, each with 310,000 voters. Of these, Panchiao, Chungho, Hsinchuang and Sanchung will each have a legislative representative, leaving 25 other townships and cities to be sliced up for the remaining eight seats. Therefore, legislators with overlapping support bases will have to coordinate over the choice of district in which to run.
以台北縣來說，初估將劃成 12 個選區，每 31 萬人一區，其中板橋、中和、新莊、三重可確保各有一席，其餘 25 個鄉鎮市則要透過合縱連橫搶奪剩餘的 8 席，因此基本盤重疊的立委必將協調選區分配。
