Classification of objects of the administrative-territorial system of Ukraine (KOATUU) (Ukrainian: Класифікатор об'єктів адміністративно-територіального устрою України, КОАТУУ), was a national standardization system established by the State Committee for Technical Regulation and Consumer Policy on October 31, 1997,[citation needed] and went into effect on January 1, 1998.[1]
KOATUU was directly inherited from and replaced the old Soviet system SOATO of the Soviet standard system GOST, without major structural changes (although there were some nomenclatural modifications).[clarification needed] KOATUU is numbered as DK 014-97 in the system of classification and coding of technical-economical and social information in Ukraine (abbreviated as DSK TESI).
Following the passage of laws on administrative reform on 17 July 2020, KOATUU became outdated and was deprecated. In response, the Ministry of Development of Communities and Territories developed a new system to replace KOATUU called the Codifier of Administrative Territorial Units and Territories of Territorial Communities, which was approved on 26 November 2020.[1]
