The names of the States and the Unions have been described in the First Schedule. This schedule also holds that there are four Categories of State and territories – Part A, Part B, Part C and Part D.
- Part A – includes the nine provinces which were under British India
- Part B – princely states consisted of this category
- Part C – centrally administered five states

In the seventh amendment of the Constitution in 1956 the distinction between the Part A and Part B states was abolished. Subsequently states were reorganized on linguistic basis. As a result several new states were formed, eg. Haryana, Goa, Nagaland, Mizoram etc. At present there are 29 States and 7 union territories.
