India has 28 states and eight union territories, which are divided into divisions comprising several districts.

Subdistricts are most commonly referred to as tehsils, which comes under a sub-division of a district.

[1] Most subdistricts in India correspond to an area within a district including the designated city, town, hamlet, or other populated place that serves as its administrative centre, with possible additional towns, and usually a number of villages.

[2] In the Indian administrative context, states adopt various nomenclatures for their sub-district divisions, including Tehsil, Taluk, Circle, Subdivision, and Mandal.

These delineations exist beneath the level of revenue division/sub-division within the administrative framework of a district.
