This is a reduction from the previous number of boroughs. Arçabil and Çandybil boroughs were merged on February 4, 2015, and the new ''etrap'', named Arçabil, was in turn renamed Büzmeýin in January 2018. At that time the Abadan borough of Ashgabat, created in 2013 by annexing the town of Abadan and surrounding villages to Abadan's south, was abolished and its territory was merged into the newly renamed Büzmeýin borough. The former Ruhabat borough was abolished at the same time and its territory absorbed by Bagtyýarlyk borough.
