Correos

Correos is Spain's national postal service and one of the country's most historic institutions, with a heritage dating back more than 300 years. In addition to delivering mail and parcels across Spain and internationally, Correos is renowned among collectors for its innovative and high-quality philatelic issues. In recent years, Correos has combined traditional stamp collecting with blockchain technology through its pioneering Crypto Sello releases, bringing Spanish culture, history, and iconic characters into the digital age.
