In the 1950s, Nepal consisted of 34 districts. From 1962, it was divided into 14 zones; these came into disuse around 1995. Since then, Nepal is divided into five vikas kshetra (development regions) (http://www.statoids.com/unp.html; see also http://en.wikipedia.org/wiki/Nepal#Zones.2C_districts.2C_and_regions).
Presently, the Mindat locality hierarchy still uses the old zones.
