CSAB Supernumerary 2026: Registration & Choice Filling Guide

The Central Seat Allocation Board (CSAB) has officially announced the commencement of the CSAB Supernumerary 2026 registration and choice filling process. This specialized round is a critical opportunity for students hailing from specific Union Territories—namely Andaman & Nicobar Islands, Lakshadweep, Daman & Diu, and Dadra & Nagar Haveli—who seek admission into the prestigious National Institutes of Technology (NITs), Indian Institutes of Information Technology (IIITs), and other Government Funded Technical Institutions (GFTIs) under the NIT+ system.
