Iceland's national postal service, known as Íslandspóstur or Pósturinn, has a long history dating back to 1776. That's when Christian VII, the King of Denmark and Iceland, mandated establishing a postal service in the country. The first Icelandic postage stamps were introduced in 1873, marking the organization of the Icelandic postal system and the opening of the initial post offices.

Over the years, there have been significant developments in Iceland's postal service. In 1935, the postal service and the national telephone company merged under Póstur og sími (Post and Telephone). However, in 1998, the state-owned company underwent a split, resulting in two separate entities: Landssími Íslands (the telephone company) and Íslandspóstur (the postal service). Landssími Íslands has since been privatized.

Today, Íslandspóstur is one of the largest employers in Iceland, with almost 1,200 employees. The company plans to expand its distribution network and improve service quality by opening multiple new post offices nationwide. This expansion aims to provide better accessibility to postal services for the population of Iceland.

As the national postal service, Íslandspóstur is crucial in facilitating communication and delivering mail and packages across Iceland.
