Revenue division in the context of "Chennai district"

A district (zila), also known as revenue district, is an administrative division of an Indian state or territory. In some cases, districts are further subdivided into sub-divisions, and in others directly into tehsils or talukas. As of 9 November 2025, there are a total of 780 districts in India. This count includes Mahe and Yanam which are Census districts and not Administrative districts and also includes the temporary Maha Kumbh Mela district but excludes Itanagar Capital Complex which has a Deputy Commissioner but is not an official district.

India is a union of states and union territories as per article 1 of the Indian Constitution. Some states and union territories are further divided into divisions, which are made up of groups of districts. A division is led by an officer of the Indian Administrative Service, known as a divisional commissioner. There are 111 divisions in India.

The states of Andhra Pradesh, Goa, Manipur, Mizoram, Sikkim, Tamil Nadu, Telangana, and Tripura, Kerala as well as five of the union territories are not divided into divisions. Instead, these states and territories go directly from the state to the district level for administrative purposes.
