The administrative divisions of India are subnational administrative units of India; they compose a nested hierarchy of country subdivisions. Indian states and territories frequently use different local titles for the same level of subdivision (e.g., the Mandals of Andhra Pradesh and Telangana correspond to Tehsils of Uttar Pradesh and other Hindi-speaking states and Talukas of Gujarat, Goa, Karnataka, Kerala, Maharashtra, and Tamil Nadu).
The smaller subdivisions (villages and blocks) exist only in rural areas. In urban areas, urban local bodies exist instead of these rural subdivisions.
The States have been grouped into six zones having an Advisory Council "to develop the habit of cooperative working" among these States. Zonal Councils were set up vide Part-III of the States Reorganisation Act, 1956. The North Eastern States' special problems are addressed by another statutory body - The North Eastern Council, created by the North Eastern Council Act, 1971. The present composition of each of these Zonal Councils is as under:
India is composed of 29 states and 7 union territories (including a national capital territory). The union territories are governed by administrators, appointed by the President of India. Two of the territories (Delhi and Puducherry) have been given partial statehood, with elected legislatures and executive councils of ministers, but limited powers.

This is a list of unofficial, or quasi-official, regions of India. Some are geographic regions, others ethnic, linguistic, dialect, or cultural regions, and some correspond to historic countries, states or provinces.

|The six regions of India|
Some states consist of regions, which have no official administrative governmental status. They are purely geographic regions; some correspond to historic countries, states or provinces. A region may comprise one or more divisions, averaging about three divisions per region. However, the boundaries of the regions and the boundaries of the divisions do not always coincide exactly. So far there has been no movement to give the regions official administrative status. If this was to be done, it would presumably require that the boundaries of the regions be slightly modified so that they correspond exactly with their constituent districts.
Some of the Indian states are subdivided into divisions which have official administrative governmental status and each division is headed by senior IAS officer called Divisional Commissioner, each further comprising several districts:
States and territories (or divisions) are further subdivided into districts (zilla), of which there are 696 (as of 2016). Each District is headed by an IAS officer called District Magistrate.
Tehsils, talukas, mandals, sub-divisions, CD Blocks, headed by a Tehsildar or Talukdar or MRO or Block Development Officer, comprise several villages or village clusters. The governmental/ elected bodies at the Tehsil level are called the panchayat samiti.
States use varying names for their sub-districts. Detailed information is as follows:
|Himachal Pradesh||Tehsil/ Sub-tehsil||109|
|Jammu and Kashmir||Tehsil||59|
|West Bengal||CD Block||341|
|Union Territory||Sub–district||Number of
|Andaman and Nicobar Islands||Tehsil||7|
|Dadra and Nagar Haveli||Taluka||1|
|Daman and Diu||Taluka||2|
The block or Community development block or C.D.Block is often the next level of administrative division after the tehsil.
Villages are often the lowest level of subdivisions in India. The governmental bodies at the village level are called Gram Panchayat, of which there were an estimated 256,000 in 2002. Each Gram Panchayat covers a large village or a cluster of smaller villages with a combined population exceeding 500 Gram Sabha. Clusters of villages are also sometimes called Hobli or Patti.
Certain governmental functions and activities - including clean water availability, rural development, and education - are tracked at a sub-village level. These hamlets are termed "habitations". India is composed of 1,714,556 habitations  In some states, most villages have a single habitation; in others (notably Kerala and Tripura) there is a high ratio of habitations to villages.
A metro area usually comprises multiple jurisdictions and municipalities: neighbourhoods, townships, cities, exurbs, suburbs, counties, districts, states, and even nations like the eurodistricts. As social, economic and political institutions have changed, metropolitan areas have become key economic and political regions. Metropolitan areas include one or more urban areas, as well as satellite cities, towns and intervening rural areas that are socio-economically tied to the urban core, typically measured by commuting patterns The metropolitan cities of India are: Mumbai, New Delhi, Kolkata, Chennai, Pune, Hyderabad and Bengaluru.
