The Dominican Postal Institute (INPOSDOM)


The logo of INPOSDOM has the tricolors of the Dominican flag with a bird carrying a letter with its beak in the center and the acronym “INPOSDOM,” the first five letters in red and the last three in blue. This logo is present at the INPOSDOM Palace in Santo Domingo, the various post offices and on it the uniforms worn by the letter carriers.

The Dominican Republic has the Instituto Postal Dominicano (INPOSDOM) which is the official mailing system. It’s based at the Palacio del Instituto Postal Dominicano (INPOSDOM Palace) in Santo Domingo. Its network of post offices covers the entire country. It offers more than just mailing documents, but also several services regarding mailing packages, electronic money transfers, speed up mailing and more. In addition, it’s the cheapest courier in the country. In this article we will present a good initial understanding of all aspects of INPOSDOM.

Mailing in the Dominican Republic goes as far back as the time it was a territory of the Spanish Empire. The modern mailing system dates from the times of the Trujillo dictatorship 1930 – 1961. During that time the Palacio de Correo was built in the 1950’s, until then the most modern building of the Dominican postal system. In November 16, 1963 via the 40 law the Dirección de Correos was crested. In November 15, 1985 the Dirección de Correos ceased to exist and was replaced by the Instituto Postal Dominicano (INPOSDOM). Despite the change, the INPOSDOM continue to operate from the Palacio de Correo. In 1993 was inaugurated the current Palacio del Instituto Postal Dominicano in the Centros de los Héroes section of Santo Domingo, having replaced the Palacio de Correo which was demolished.

The Dominican Postal Institute Palace

The Dominican government, on the orders of the President Dr Joaquín Balaguer, built the current Palacio del Instituto Postal Dominicano or the Dominican Postal Institute Palace (INPOSDOM) which substited the demolished Palacio del Correo. It was inaugurated in 1993. This is the headquarters if the institution and the center of the Dominican mailing system. All documents and packages sent from abroad via a public mail system arrives here prior to being sent to the corresponding post office. All documents and packages mailed in the Dominican Republic via one of INPOSDOM post offices, regardless if they are travelling within the country or going to abroad, arrives here before it leaves the country.

INPOSDOM Post Offices

INPOSDOM has several post offices in Greater Santo Domingo and one post office in each provincial capital and other important cities and towns in the interior. Despite when the INPOSDOM Palace was inaugurated there were a few post offices built in a similar architecture (all identical), most INPOSDOM post offices are not defined by a particular architectural style. Many INPOSDOM post offices are inside department stores and other businesses. Many of the post offices are in need of a much needed maintenance, but this could be changing soon as it appears the institution is getting an upkeep.

In the Santo Domingo Metropolitan Area several INPOSDOM post offices are identical and resemble a miniature version of the INPOSDOM Palace.
The INPOSDOM post office on Calle del Sol and Calle San Luis in Santiago gets a mention for being perhaps in the most lavish building of all Dominican post offices. It was built in the eqrly decades of the XX century in the Neoclassical style with four Iconic columns on the sides facing each street.
Most INPOSDOM post offices are not defined by an architectural style. Instead they are in independenct buildings with not much architectural details, in simple store fronts, in historic buildings, etc. While there is no news regarding any changes to the logo of the institution, it’s noticeable the different logo on the left side of the facade.

Dominican Letter Carriers

Unlike in countries such as the United States or Canada, the sight of letter carriers in the Dominican Republic is not a defining aspect of the scenery, particularly urban ones. Despite appearances, the Dominican Republic do have letter carriers. Unlike in other countries, Dominican letter carriers don’t have a fleet of INPOSDOM vehicles, but rather travel to their place of delivery on their own vehiles, particularly in motorcycles. This perhaps makes letter carriers in Dominican streets to be less obvious.

The uniforms of Dominican letter carriers is a blue shirt and usually paired with a navy blue cap. On the shirt and on the cap is the logo of INPOSDOM.

Approximately 11 Dominican letter carriers were recognized for their service at INPOSDOM on October 2, the World Letter Carrier Day. This event took place at the INPOSDOM Palace in Santo Domingo.

As elsewhere, Dominican letter carriers have been impacted by the rise of technology and of consumption. In the 1990’s it was still the case that Dominican letter carriers would carry around 90% of all the correspondence in the Dominican Republic and of those 70% was documents and 30% packages. Today this has been reduced to 40% overall or upwards of 4 million doduments and packages, of those 70% are packages and 30% documents, the inverse of how it was in the 1990’s. In part this is due to increasing competition from private courier companies, but mostly to the increase of technology which has reduced the volumes of letters. INPOSDOM has added delivering packages in order to increase the demand of letter carriers. Costs of using INPOSDOM instead of private companies courier are the cheapest in the Domimican market, around 40% less. By all accounts, it seems this service is going to disappear as people use technology for communicating and even companies are preferring sending their bills online than physically.
