Ang isang numero ng PO BOX ay maaaring mas mababa sa o higit sa apat na digit. Para sa mga kahon ng post office, ang pangkalahatang panuntunan ay ang bawat kahon ay may sariling ZIP + 4 code.
Ang huling apat na digit ay madalas na isa sa mga sumusunod:
1. Zero kasama ang huling tatlong mga numero ng numero ng kahon (eg. PO BOX 1001, Los Angeles CA 90001-0001).
2. Ang huling apat na digit ng numero ng kahon (eg. PO BOX 9991, Twin Peaks CA 92391-9991).
3. Kung ang numero ng kahon ay mas mababa sa apat na digit, sapat na mga zero ang inihanda sa harap ng numero ng kahon upang makabuo ng isang apat na digit na numero(eg. PO BOX 1, Shreveport LA 71161-0001).
Gayunpaman, walang pare-parehong panuntunan, ang zip code kasama ang apat ay para sa sanggunian lamang, ang ZIP + 4 code ay dapat na indibidwal na tiningnan para sa bawat kahon sa USPS offical website.
