Postal services in Azerbaijan began to develop during the Safavid dynasty (16th century). The formation of the postal network in the Nakhchivan Autonomous Republic dates back to the beginning of the 19th century. According to official data, the first postal expedition was organized in Nakhchivan on March 12, 1828, and in 1830, a first-class post office (an official office or station where postal services were provided) began operating in the city. This indicates that Nakhchivan was one of the early postal centers in the region. In the second half of the 19th century, the postal network expanded further, and the Julfa region in particular played an important role. In 1863–1872, postal communication was established between Tbilisi and Julfa, a post office was established there, and international letter exchange with Iran and the Islamic Republic was carried out. This created conditions for Nakhchivan to join international postal relations.In addition, the presence of materials related to the Julfa post-telegraph office among the documents kept in the Nakhchivan State Archive also indicates that the postal and telegraph network in the region was already developed at the end of the 19th century - the beginning of the 20th century.After the establishment of the Ministry of Communications of the Republic of Azerbaijan on September 15, 1918, the first post office was opened in the city of Nakhchivan. In the 1920s, communication services that partially met the needs of the population developed, and postal and telegraph networks were established in Ordubad, Julfa, and Sharur. A postal and telegraph agency was opened in the city of Nakhchivan. The start of operation of postal and telegraph departments in the Shahbuz and Abraqunus district centers coincided with that period. In general, during the 1930s, post offices were established in all district centers of Nakhchivan, and postmen were assigned to serve the villages, and the population was completely provided with postal communication services.In subsequent periods, the quality and quantity of postal and telegraph services provided to the population in Nakhchivan further developed, and the length of telegraph lines was increased to 525 kilometers.In general, as a result of this historical development, the postal system in Nakhchivan gradually expanded, turned into a regional network covering various settlements, and continues to develop in the modern era.
