Postal codes in Lithuania
From Wikipedia, the free encyclopedia
Postal codes in Lithuania since 2005 are 5 digit numeric, ISO 3166-1 alpha-2 prefix is allowed, with that the format is LT-NNNNN.[1][2][3][4] Currently, Lithuania has a total of 16,514 postal codes.[5]
Prior to 2005, it was NNNN, which was the old Soviet NNNNNN format with the first 2 digits (23) dropped.[6][7][8]
The standardized format for postal codes was established by Lietuvos paštas, the Lithuanian state postal company, following the guidelines of the Universal Postal Union (UPU).[9] The 5 digits are divided as follows: the first two refer to the routing district and the last three to the delivery office.[4] Within the country, only the five-digit postal code is applied. For example, "14116". In the case of international mail, the prefix "LT-" is mandatory as the country code, according to ISO 3166-1 alpha-2 conventions. An example, for sending to Lithuania, would be "LT-01103".[10]
