- ILIrene LeungJun 1, 20265.0Effective: There was a notice posted on the door. On Saturday, May 30, 2026, this post office closed. If you need PO service go to 123 W. Holt or the other one farther east on Holt or Arrow Highway/3rd St in Upland. I liked this P.O. because it was smaller and the staff was very nice, pleasant and courteous.
