It has jurisdiction over the state of West Bengal and the Union Territory of the Andaman and Nicobar Islands.

The High Court building's design is somewhat based on the Lakenhal (Cloth Hall) in Ypres in Flanders, Belgium.

The seat of the Calcutta High Court is at Kolkata, capital of West Bengal.

The Calcutta High Court extended its Circuit Bench in Port Blair, the capital of the Andaman and Nicobar Islands and in Jalpaiguri, the divisional headquarters of the North Bengal region.

On 7 February 2019, President Ram Nath Kovind finalised the opening of the other circuit bench in Jalpaiguri, West Bengal with the jurisdiction area[6] within 5 districts- Darjeeling, Kalimpong, Jalpaiguri, Alipurduar and Cooch Behar.

The design, by then government architect Walter Granville, was loosely modelled on the 13th-century Cloth Hall at Ypres, Belgium.
