The United Nations Postal Administration (UNPA) is pleased to announce the launch of UN Crypto Stamps – connecting a new generation of United Nations stamps with blockchain technology.

Designed by Sergio Baradat of UNPA, the stamps support the Secretary-General’s strategy on new technologies, and were developed in conjunction with the United Nations Office of Information and Communications Technology.

The stamps in the denominations of $7.75, CHF 8 and €7 feature a unique design of the UN Headquarters Buildings in New York, Geneva and Vienna, and were printed by Royal Joh. Enschedé of The Netherlands.

The total print quantity is 90,000 stamps or 30,000 per each denomination.

Each stamp sheet includes a unique secret code hidden behind a scratch-off area which enables its owner to activate exactly one counterpart of that stamp on the block chain as a digital collectible.

The creation, ownership, exchange, and trading of the digital stamps is managed through a smart contract deployed on the Ethereum blockchain. There are 51 variations of the UN Crypto Stamps, as each sheet features one of the 17 Sustainable Development Goals.

You are encouraged to find and collect all 51 variations! To learn more about how UN Crypto Stamps work, please visit

UN Crypto Stamps are sold exclusively by the UNPA. Purchase the stamps at or the United Nations stamp shops in New York, Geneva, and Vienna.
