Before the Spanish arrived, in America there were already postal systems. With the arrival of the European system, there is a miscegenation of postal forms that is good to know. Panama is part of that miscegenation.
In the year of 1942, by Decree 463, of July 16, the denomination of post offices was changed, being divided into sections and dependencies, with the object provided that it could attend, in an adequate manner, the new needs of the growing Republic. Thus, those that were previously Postal Agencies became Administrations and the Subaltern Administrations were called Agencies. The Postal Post Offices that were established or were within the perimeter where Correos Administrations work will be called Branches or Postal Agencies.
