To claim the title of World’s Largest Mailbox, this structure had to be fully functional.

Drop a line from a mailbox that truly delivers on size! The World’s Largest Mailbox is not just an incredible photo opportunity; it’s a fully operational, USPS-approved post office. Climb the built-in stairs to reach the letter slot of this towering, bright red structure. When you deposit your mail, the giant flag on the side actually raises to signal a pick-up! It’s a wonderfully interactive experience that delights visitors of all ages. Sending a postcard or letter from this colossal mailbox, complete with a special Casey postmark, creates a unique and memorable souvenir for friends and family back home. Your friends and family will be amazed to receive mail postmarked from Casey!

If you are looking for a great shot for your vacation album, then this is the place for you. Not only can your crew take a picture of you from down below, but you have a great view of Casey from up above.​

Tip: Purchase Casey-themed postcards from local shops and mail them here for an authentic ‘Big Things’ experience. Don’t forget to take a picture as the flag goes up!
