Diglipur falls under the administrative jurisdiction of the Andaman and Nicobar Islands, a Union Territory governed by the Central Government of India through an appointed Lieutenant Governor.
At the local level, Diglipur is a tehsil within the North and Middle Andaman district, which has its headquarters in Mayabunder. Local governance is managed by Gram Panchayats (village councils), which oversee civic amenities, sanitation, and rural development in the town and its surrounding settlements. Law and order is maintained by the Andaman and Nicobar Police. Additionally, due to its strategic maritime location in the Bay of Bengal, there is a prominent presence of the Indian Navy and Coast Guard nearby, notably at INS Kohassa.
