The Woodland Valley Post Office is Woodland Valley's own facility for posting, receipt, sorting, handling, transmission or delivery of mail. The post office also sells stamps for stamp collections and does clammygrams if asked. Jeremiah Tortoise works there in addition to running his general store. Most of the mail ends up arriving late due to Jeremiah Tortoise, who is slow at delivering the mail. In "A Strange Bird," Bear received a two-week old postcard from a penguin named Puck from the South Pole and finds out Puck is paying a visit to the Big Blue House today. The store accepts clams, Woodland Valley's official currency, as payment and it has to be exact change only.

Woodland Valley Post Office was first introduced in "Read My Book" and was seen more in later episodes.
