The constitution has a preamble and 470 articles, which are grouped into 25 parts. With 12 schedules and five appendices, it has been amended 104 times since its adoption; the latest amendment became effective on 25 January 2020.

• Note: At the time of its commencement the Constitution of India contains 395 articles in 22 parts and 8 schedules.
