• 1. Bangladesh — Longest Border (4,096.7 km): Bounded by the Radcliffe Line. Bordered by 5 Indian States: West Bengal, Assam, Meghalaya, Tripura, and Mizoram. (Tripura is unique because it is bounded by Bangladesh on three sides).

• Maritime Neighbors:
  • Sri Lanka: Separated from Tamil Nadu by the shallow Palk Strait and the Gulf of Mannar.
  • Maldives: Located south of Lakshadweep, separated from Minicoy Island by the 8 Degree Channel.

• Constitutional Organization: As of today, the Republic of India comprises exactly 28 States and 8 Union Territories (UTs).
• Recent Historical Reorganizations:
  • On 31 October 2019 (National Unity Day), the former state of Jammu & Kashmir was officially bifurcated into two separate Union Territories: Jammu & Kashmir and Ladakh.
  • On 26 January 2020, the two western UTs of Dadra and Nagar Haveli and Daman and Diu were merged into a single Union Territory with Daman as its administrative capital.
