Omniva is an international post and logistics company based in Tallinn, Estonia, that targets the Baltic states.

[2][3] The name Omniva was adopted in June 2014; the company was previously called AS Eesti Post, whose history can be traced back to the beginning of postal services on Estonian territory (at that time part of the Swedish Empire) in 1638.

Omniva retains the name Eesti Post for the division of the company responsible for the national postal service of Estonia.

[4] Before 1917, 157 post offices operated in the territory of the Republic of Estonia, in addition to three independent state telephone exchanges.

[4] On 25 February 1918, the German occupation authorities took over the Tallinn post office and liquidated the existing postal system.
