Out of This World Mailboxes


Human beings are a creative lot, and they think outside the box. Some of the ordinary things made extraordinary are the places where mailboxes are stationed. Case in point, the world’s highest post office sits at 17,090 feet atop the North Everest Base Camp.

For over 125 years, Michigan state has been home to the world’s only floating post office that sends and receives mail on ships operating on Lake Michigan.

In the Galapagos Islands hold thousands of letters stored in crates, boxes and barrels, visitors comb through postcards to see whether they can get mail of addresses they know and deliver.

These are all mailboxes setup above water, and below we look at mailboxes created underwater.

Pulau Layang-Layang, Malaysia


Although not officially recognised, the Pulau Layang-Layang mailbox is the deepest mailbox setup 131 feet underwater.

Malaysia capitalises on the postcard sales as they in-print a special postmark and stamp it with a Malaysian Book of Records logo making it a collectible item for people receiving the letter.

The symbols arouse curiosity making the recipient add Pulau Layang-Layang to their bucket list of places they want to visit.

Hideaway Island, Vanuatu


Set up at Hideaway Island marine sanctuary, the Post office is 3 meters underwater. The officials of the island thought it best to introduce the mailbox so that tourists can dive deep and soak in the beautiful coral reefs before posting their waterproof postcards.

Besides, the underwater mailbox supplements the high altitude mailbox on the same island that sits atop of a live volcano.

Risor Norway


A marine dry post office that’s constructed from a diving bell. The post office is the only fully functional dry office in the world and serves residents and tourists during the warm summer months.

It’s constructed in Risor a small town surrounded by small lakes and hills in Norway’s Southern coast.

The post office sits at a depth of 13 feet up against a pier. Despite being shut down temporary in 2011 due to bloated running costs and dwindling numbers of letters, the local business and tourism board pitched in to have this unique post office keep running.

Susami Bay, Japan


The former postmaster (Toshihiko Matsumoto) thought of an ingenious way of to boost the Kumano Kodo pilgrimage that happens in the small fishing town of Susami.

In 1999, the mailbox was set up, and the local dive shop sells the waterproof paper and oil-based paint marker contributing to the local economy.

The underwater mailbox has become a hit with people who prefer vacations on the beach. This particular mailbox receives between 1000-1,500 pieces of mail every year. The mailbox, however, changes two times every year since the seawater is too corrosive.

Now you know about some of the craziest mailbox settings across the world. You should consider visiting the underwater mailboxes at least once in your life.
