Since 16 February 2026 West Bengal has two Registrars of Companies. RoC Kolkata-I covers only the district of Kolkata. RoC Kolkata-II covers the rest of the state. Because Kolkata district is the city proper, several of the city's best-known business addresses fall under Kolkata-II.
| Area | District | Registrar |
|---|---|---|
| BBD Bagh, Park Street, Camac Street, Ballygunge, Alipore, Bhowanipore, Tollygunge, Jadavpur, Behala, Shyambazar | Kolkata | Kolkata-I |
| Salt Lake (Bidhannagar) including Sector V, most of New Town and Rajarhat, Dum Dum, Barrackpore, Barasat | North 24 Parganas | Kolkata-II |
| Howrah | Howrah | Kolkata-II |
| Rest of West Bengal, including Durgapur and Siliguri | Other districts | Kolkata-II |
