World’s first underwater post office

Sharing is caring!

Vanuatu Post has created an official Post Office with a difference. It’s the world’s first and only Underwater Post Office.


This official and currently unique postal location was opened for business on Monday May 26, 2003. A special flag floats above the site.

Vanuatu Post encourages visitors to literally look below the surface of this beautiful country and grab a mask, fins and snorkel, and visit the Underwater Post Office. They guarantee you will discover unlimited fun and unforgettable adventures!

Situated within the Hideaway Island marine sanctuary, the Post Office sits in around three meters of water and both divers and snorkelers are able to post special “waterproof postcards”. If snorkelers cannot duck-dive down that far, Hideaway Island staff will be on the spot to help out.

During opening hours the cards will be cancelled/embossed by the postal staff in the Underwater Post Office. Instead of being stamped with ink to show that the card has been sent, the Post office has developed a new embossed cancellation device.

All are guaranteed to receive the special cancellation from this unique underwater paradise before being delivered both locally and internationally.
