On December 10, 1839, via government decree, the first rulebook for mail was drafted and the “Servicio Nacional de Correos” was created.

[2] On March 23, 1868, during the government of Jesús Jiménez Zamora, a contract was signed between the Secretaría de Fomento and Lyman Reynold with the intent of setting up a telegraphic connection in Cartago, San José, Heredia, Alajuela and Puntarenas.

Law number 7768, of April 24, 1998, transformed the institution into what is now known as Correos de Costa Rica S.A., a public company structured as a for-profit enterprise, not dependent on the central government.

It also houses the Museo Filatélico de Costa Rica (Philatelic Museum).

[2] In the 2010 decade the company diversified its offerings with the introduction of the freight forwarding service "Box-Correos" which assists Costa Ricans who wish to shop online with a virtual US address.
