CSAB 2026 Seat Acceptance Process – Step by Step After Allotment
Everything you must do after your CSAB Round 1 allotment — from fee payment to document upload to physical reporting.
Overview: What Happens After CSAB Allotment
Once CSAB Round 1 allotment results are published on csab.nic.in, you enter a short but critical action window — typically just 2–3 days. During this window you must pay the seat acceptance fee online, upload documents, and indicate whether you want to Freeze your current seat or participate in Round 2 for a potential upgrade.
Missing this window means your allotment is automatically cancelled and the seat goes back to the pool for Round 2. There are no extensions. Given how tight CSAB timelines are, check the allotment result immediately when it is announced and complete all steps the same day if possible.
After Round 2 (your final allotment), you must physically report to the allotted institute within the reporting deadline, which is usually 5–7 days after Round 2 results. Physical reporting involves document verification and fee payment at the institute.
Step-by-Step Seat Acceptance Process
Log in at csab.nic.in after Round 1 result
Use your JEE Main Application Number and password. Check the allotment letter which shows your allotted institute, branch, category seat type, and allotment status. Download and save this letter.
Pay the seat acceptance fee online
Pay Rs. 30,000 (General/OBC/EWS) or Rs. 15,000 (SC/ST/PwD) through the payment gateway on csab.nic.in. Accepted modes: net banking, credit/debit card, UPI. Save the payment receipt. This must be done within the specified window — typically 24–48 hours after the allotment.
Upload required documents
Upload scanned copies of Class 10 certificate, Class 12 marksheet, JEE Main scorecard, category certificate (if applicable), and passport photo. Ensure scans are clear, legible, and within the specified file size. Incomplete or blurry uploads can cause issues at physical reporting.
Choose: Freeze your seat or participate in Round 2
After fee payment, indicate your response: Freeze (accept current seat, skip Round 2 upgrade) or Participate in Round 2 (keep seat but try for upgrade). If you are happy with your allotment and it is in your top choices, Freeze. If you have high-priority choices above your current allotment that might have vacancies in Round 2, participate in Round 2.
Wait for Round 2 result (if not frozen)
Round 2 allotment is announced approximately 5–7 days after the Round 1 reporting deadline. If you got an upgrade, a new allotment letter is issued for the better seat. If no upgrade, your Round 1 seat is confirmed. Either way, the fee you paid carries forward.
Physically report to the allotted institute
Travel to your allotted institute and present all original documents for verification. Pay the remaining institute fees (tuition, hostel, etc.). Complete the enrollment process. Missing the physical reporting deadline results in seat cancellation with no refund of the seat acceptance fee.
