CSAB Special 2026 Registration Starts After a Momentary Delay, Mock Allotment on 31 July 2026: Full Details Here

The Central Seat Allocation Board (CSAB) has officially initiated the online registration and choice filling process for the CSAB Special Rounds 2026 on 28th July 2026 at csab.nic.in. The registration portal was activated after a brief momentary technical delay on July 28. The mock seat allotment will be out on 31st July 2026 at csab.nic.in. The portal is currently open for both CSAB Special Round and DASA UG 2026 candidates.

Candidates who qualified JEE Main 2026 can apply for admission to vacant seats in NITs, IIITs, IIEST Shibpur, SPAs, and other GFTIs through CSAB Special Rounds 2026. IITs do not participate in CSAB counselling, as the process is only for filling vacant seats in the NIT+ system after JoSAA Round 5.

CSAB Special 2026 Registration Begins After Brief Delay

The registration window was originally slated to open early on July 28, 2026. However, due to administrative and technical considerations, the portal faced a brief hold, prompting CSAB to temporarily defer the start before activating the live portal later in the day.

Candidates can now visit the official portal at csab.nic.in to create their login accounts, pay the Special Round Enrolment Fee (SREF), and submit their preferences. Authorities have advised candidates not to wait until the final hours to avoid payment gateway congestion.
