Understanding Puducherry's Geographical Boundaries

The Union Territory of Puducherry is unique because it is not a single contiguous land mass. Instead, it is made up of four distinct, non-contiguous districts located in different states of India.

To determine which states share boundaries with the Union Territory of Puducherry, we need to look at the location of each of its constituent districts:

• Puducherry district: This district is located on the eastern coast and is surrounded by the state of Tamil Nadu.
• Karaikal district: Also located on the eastern coast, south of Puducherry district, and is surrounded by the state of Tamil Nadu.
• Yanam district: This district is located in the Godavari delta region on the eastern coast and is surrounded by the state of Andhra Pradesh.
• Mahe district: This district is located on the western coast and is surrounded by the state of Kerala.

Since the Union Territory of Puducherry comprises these four districts, its overall boundaries are shared with the states that surround these individual districts.

Based on the location of its districts, the Union Territory of Puducherry shares boundaries with:

• Andhra Pradesh (via Yanam)
• Kerala (via Mahe)
• Tamil Nadu (via Puducherry and Karaikal)

Therefore, the states that share boundaries with the Union Territory of Puducherry are Andhra Pradesh, Kerala, and Tamil Nadu.
