Yes, scuba divers and free divers can send mail from underwater post offices and mail boxes now. Imagine that…
The underwater post office off of Hideaway Island in Vanuatu may have been the first underwater post office for scuba divers, but no longer. Japan has underwater postal services now as well. In fact they have the deepest underwater post box in the world.
Perhaps the distinction comes when you consider that Vanuatu has a post office as well as a post box, whereas the underwater postal services offered in Japan is only via a post box. Nonetheless, these underwater mailboxes are very popular among scuba divers and free divers as well.
The Vanuatu post office is located about 160 ft off the coast of Vanuatu. The underwater post office was constructed out of a fiberglass water tank and it lies about 10 ft below the surface.
It opened in 2003 and was the idea of the local resort owner and local postmaster over drinks to make it possible for vacationers to send post postcards form below the surface.
Vanuatu, aside form its underwater mail delivery, offers great diving experiences as seen in the video below.

“Every week hundreds of postcards are dropped off at the underwater post office,” Timbaci tells Smithsonian.com. “The number goes up when cruise ships come into port.”
As a postal manager, it’s Timbaci’s job to ensure that the postcards, which are made of waterproof plastic and embossed with a special stamp, are collected on time at 3 p.m. each day. (The post office developed a special metal device that marks each postcard without using ink, which would smear on contact.)
So as it turns out the Vanuatu may have been first, but Japan now also has an underwater post office just off a small seaside town of Susami. However, this post office holds the Guinness Book Of World Record's as the deepest underwater post office. So it is really an attraction for scuba divers that want underwater postal services.
