The Underwater Mailboxes On Planet Earth


Postcards are sent across the world. In the United States alone, 2014 records show that the Post Office shipped out 770 billion letters. Naturally, postcards are sent to mailboxes, and that means many people still check their mail manually not just digitally.

To make it more interesting, people send these postcards through underwater boxes when they are on holiday to show people back home how much fun they’re having. Today, we look at some of the marine mailboxes across the world.

Hideaway Island Vanuatu


A Post Office sitting three meters deep in water. It’s the first officially recognized underwater mailbox that is accessed only by divers and snorkelers. The only postcards sent to this mailbox are waterproof.

The post office staff are on standby to retrieve new mail and ensure that the mail gets delivered promptly. Divers swim through beautiful balmy coral waters passing by stunning underwater coral pieces and sea turtles as they make their way to the mailbox.

The Island’s main purpose of installing an underwater mailbox was to ensure that visitors and residents would jump in the water to see the beautiful and pristine coral reefs.

Susami Bay, Japan


A one time record holder for the deepest underwater mailbox sitting at 33 feet of water. The mailbox was set up in 1999 in the fishing town of Susami to promote the Kumano Kodo pilgrimage.

A local dive shop supplies the water-resistant postcards and an oil-based paint marker to write the message.

The mailbox receives between 1000 and 1,500 pieces of mail annually and an employee of the Yamatani Dive shop is charged with collecting mail from the underground box every several days and posts them.

The mailboxes are made of cast-iron and changed two times every year due to the seawater’s destructive nature.

Pulau Layang-Layang, Malaysia


Official records place this mailbox as the deepest set mailbox in the world sitting at 131 feet. The mailbox was installed in 2015 and is the country’s second mailbox project.

The postcards are waterproof and carry a special postmark, they are also stamped with a logo for the Malaysia Book of Records making them collectable souvenirs.

35-year-old Ritchie Lester and 25-year-old Victory Marden are two postmen assigned the duty to the mailbox to collect, sort and send mail from this mailbox.

Risor, Norway


One of the coldest places in the world is the Nordic region. Risor is a small town in Norway’s Southcoast. The underwater mailbox is set up as a fully functioning post office and the only dry underwater post office on the planet.

However, the post office comes to life during summer months when the climate is a bit warmer, and tourists throng the town in droves.

Many curious mailboxes across the world are worth visiting or reading about some of them have gotten quite popular and do require a short wait time however the mail boxes mentioned above are worth the wait and adding to your bucket list.

The mailboxes go to show how humans can find ways of communicating. We wait with anticipation to see when the next mailbox will be launched.
