The Central Seat Allocation Board conducts CSAB counselling registration 2025 for students who weren't allotted a seat through JoSAA counselling, or who are eligible under specific quotas. Based on JEE Main 2025 ranks, CSAB conducts three separate rounds—NEUT, Special, and Supernumerary. The CSAB NEUT counselling is already in progress, and the Round 1 seat allotment result has been released. Up next is the special round registration, starting on July 30, followed by the supernumerary round from August 24.
What is CSAB?
The Central Seat Allocation Board (CSAB) oversees counselling for admission to undergraduate engineering and technical programs, based on JEE Main scores. It primarily steps in after JoSAA counselling concludes, managing vacant seats through additional rounds. CSAB conducts three different types of counselling rounds, each with a specific purpose and target group of students.
Let's look at the different categories under CSAB 2025 counselling:
CSAB Special Round:
This round fills the vacant seats left unoccupied in NITs, IIITs, and GFTIs after JoSAA counselling ends. All interested candidates must register again, even if they participated in JoSAA. The special round is open to students who appeared for JEE Main 2025 and meet the eligibility requirements.
CSAB NEUT Round:
The NEUT (North Eastern and Union Territories) round is exclusively for students from northeastern states and union territories that lack sufficient technical education facilities. Seats are allotted under the Government of India's reservation scheme in AICTE-approved institutions for engineering, architecture, technology, and pharmacy courses.
CSAB Supernumerary Round:
This round is only for candidates from Andaman & Nicobar Islands, Lakshadweep, Daman & Diu, and Dadra & Nagar Haveli. It allocates supernumerary seats available at NIT Calicut, NIT Durgapur, and SVNIT Surat.

CSAB Counselling Fees Overview
Let's look at how the counselling fee differs based on the type of round and candidate category. While the registration itself doesn't require a fee, payment becomes mandatory once seats are allotted.
1- CSAB Special Round: Counselling Fee Structure
After registering for the Special Round, candidates must pay the Special Round Enrollment Fee (SREF). The payable amount varies by candidate type, which is decided based on previous participation in JoSAA or CSAB rounds and fee refund status.
Here's the updated fee structure with adjusted order:
All payments must be made online using Net Banking, Debit/Credit card, or SBI e-challan.
2- CSAB NEUT 2025: Counselling Fee Structure
In the NEUT round, candidates must confirm their seats by paying a Seat Acceptance Fee (SAF) of ₹5,000. This fee must be paid after each round of allotment as per the timeline provided on the official website.
3- CSAB Supernumerary Round (PwD): Counselling Fee Structure
Candidates participating in the Supernumerary round must pay the Supernumerary Seat Acceptance Fee (SSAF). This includes a ₹5,000 non-refundable processing charge.
The breakdown is as follows:
If you've already paid fees during JoSAA 2025 or CSAB Special Round, the amount will be adjusted accordingly, and only the remaining balance needs to be paid.

Step-by-Step Process of CSAB 2025 Supernumerary Counselling
This special round of counselling is specifically held for Union Territory (UT) candidates and is conducted independently of JoSAA or CSAB Special rounds.
Here's how the process unfolds:
Step 1: Online Registration on CSAB Supernumerary Portal
All eligible candidates must register afresh at csab.nic.in as per the official schedule. Please note that prior participation in JoSAA or any CSAB round will not carry over to this process.
Here are the important instructions for registration:
- Login must be done using your JEE Main 2025 Application Number and the latest password (from JEE Advanced, JoSAA, or CSAB Special, if applicable).
- Only Indian Nationals are eligible for this round.
- Candidates can only register once.
- Those who didn't verify documents earlier (in JoSAA or CSAB Special) can update:
- Gender
- State of Eligibility (based on where Class 12 was first attempted)
Step 2: Filling and Locking Choices for Seat Allotment
Once registration is complete, candidates must fill in fresh program and institute choices.
- Previous preferences from JoSAA or CSAB Special Rounds are not valid here.
- It's advised to save choices frequently while filling out.
- Final locking is mandatory — either done manually or automatically by the system once the deadline ends.
- A printout can be downloaded only after locking is complete.
Step 3: Supernumerary Seat Allocation Based on JEE Main Rank
The CSAB system will allocate seats using the Common Rank List (CRL) of JEE Main 2025.
Here's how it works:
- Allocation is based purely on merit and preference.
- Candidates can be considered for all branches listed in the seat matrix.
- Seats will be assigned only from the remaining supernumerary seats, after subtracting the ones filled under the standard Home State quota for each UT.
Step 4: Uploading Documents and Paying SSAF
Candidates allotted a seat must upload the necessary documents and pay the Seat Securing and Acceptance Fee (SSAF) via the CSAB portal.
Required documents include:
Step 5: Online Document Verification
Post-upload, the CSAB team will verify your documents online.
- Verification officers may raise queries if needed.
- You must respond to these queries within the given timeframe through your login.
- Verification is mandatory to confirm your seat.
Step 6: Final Physical Reporting to the Allotted Institute
Candidates whose seats are confirmed after successful verification must report to their allotted institute in person as per the announced schedule.
- Final admission formalities, including fee payment, will be completed there.
- Any remaining amount (beyond the SSAF paid earlier) must be cleared at the institute.
- The SSAF paid will be transferred to the institute after deducting processing charges (if applicable).
