You could check your p.o. box 24/7. That part isn't closed... there's a sign on the pillar next to the kiosk that indicates what time they put mail in the boxes
They did not have a sign up that specified about po box. Normally for 95829 po boxes its 5pm. I went at 1230p today and post office had closed at 1200p but po boxes were still open. Hopefully this helps. Merry Christmas.
Lobby is open 24hrs for po box
