DU CSAS 2026 Round 1 seat allotment is released at ugadmission.uod.ac.in; students who receive an offer must log in, choose to Freeze or Accept and Upgrade, complete online document verification, pay the admission fee, and report to the allotted college within the stipulated deadline.
The Common Seat Allocation System (CSAS) is Delhi University’s centralised admission process for undergraduate programmes based on CUET UG scores. Once Round 1 results are out, each student sees one allotment and must act fast — a missed deadline means losing the seat. Knowing the steps in advance puts you in control.
- Round 1 allotment is declared on the CSAS UG portal at ugadmission.uod.ac.in.
- You have three choices: Freeze (confirm seat permanently), Accept and Upgrade (keep current seat while waiting for a better one), or Reject (decline the offer and enter subsequent rounds).
- After accepting, complete online document verification and pay the admission fee within the window shown on your dashboard.
- Physical reporting to the allotted college follows — check your college notice board and the CSAS dashboard for the exact date.
- Taking no action by the deadline is treated as a Freeze in most rounds — your seat is retained but upgrade eligibility is lost.

What is DU CSAS Round 1 Seat Allotment?
DU CSAS allots seats across Delhi University’s undergraduate programmes by matching your CUET UG rank against available seats in the college-programme preferences you locked during Phase 2. Round 1 is the first offer you receive — one allotment, one window to respond. This is provisional, not final admission. Your seat is confirmed only after you pay the admission fee and complete document verification. Until then, DU can cancel the offer if you miss any step.
DU CSAS 2026 Round 1 Schedule
DU has not published a finalised Round 1 date for all UG programmes. Based on the 2025 pattern, Round 1 is expected in the third week of July 2026 once CUET UG 2026 results are declared and Phase 2 preference locking is complete. The acceptance window is typically 48 to 72 hours after the allotment — confirm the exact deadline from your CSAS dashboard.
| Event | Expected Timeline (Based on 2025 Pattern) |
|---|---|
| CUET UG 2026 Result | First week of July 2026 |
| Phase 2: Preference Filling and Locking | Mid-July 2026 |
| Round 1 Seat Allotment | Third week of July 2026 (expected) |
| Seat Acceptance / Freeze / Upgrade Window | 48 to 72 hours after Round 1 declaration |
| Admission Fee Payment | Within Round 1 acceptance window |
| Round 2 Allotment | Late July or early August 2026 (expected) |
All dates are expected based on 2025 trends and subject to official confirmation at ugadmission.uod.ac.in.
How to Check DU CSAS 2026 Round 1 Seat Allotment
Follow these steps once the Round 1 result is declared:
- Go to ugadmission.uod.ac.in and click Login to CSAS Dashboard.
- Enter your application number and the password set during Phase 1 registration.
- Click Round 1 Seat Allotment on the dashboard to view the allotted college and programme.
- Note the acceptance deadline displayed on the dashboard — it counts down in real time.
- Download and save the allotment letter for your records and for college reporting.
Freeze, Accept and Upgrade, or Reject: What to Choose
After viewing your allotment, you must click one of three options within the acceptance window. Choose carefully — this decision affects your position in future rounds.
| Option | What It Does | Effect on Future Rounds |
|---|---|---|
| Freeze | Accepts the current allotment permanently | Exits CSAS process; no further upgrades possible |
| Accept and Upgrade | Secures the current seat while keeping you in the queue for a higher-preference option in Round 2 or 3 | If upgraded, the Round 1 seat is automatically cancelled. If not upgraded, the current seat is retained. |
| Reject / No Action | Declines the allotted seat entirely | You may participate in subsequent rounds but lose the current offer with no guarantee of a better one |
If you are satisfied with the allotted college and programme, choose Freeze. If your preference list still has higher-ranked options available, choose Accept and Upgrade — your current seat acts as a safety net. Rejecting is risky unless you are very confident a better allotment is coming; students who reject Round 1 and receive no upgrade in Round 2 may lose admission entirely.

How to Pay the Admission Fee After Round 1 Allotment
All fee payments are made through the CSAS portal only — do not pay at the college counter separately.
- Log in to your dashboard at ugadmission.uod.ac.in.
- After selecting Freeze or Accept and Upgrade, the portal redirects you to the fee payment gateway.
- Choose a payment mode: Net Banking, Debit Card, Credit Card, or UPI.
- Complete the payment and wait for the confirmation page before closing the browser window.
- Save the transaction receipt and the confirmation email sent to your registered address.
The CSAS registration fee is Rs 250 for General, OBC-NCL, and EWS students and Rs 100 for SC, ST, and PwBD students. The college-specific admission fee is shown on the payment page before you confirm — amounts vary by college and programme.
How to Report to Your Allotted DU College
Physical reporting happens after online acceptance and fee payment are confirmed. DU colleges issue separate reporting dates — watch your dashboard and the college notice board.
- Complete online document verification first by uploading scanned copies of all required documents through the CSAS portal.
- Wait for the verification approval notification from the college on your dashboard or registered email.
- Visit the college on the designated reporting date with all original documents and self-attested photocopies.
- Submit any forms the college issues on the day — medical fitness declaration, undertaking forms, etc.
- Collect your provisional admission slip or student ID form from the college office.
If online document verification fails due to discrepancies, the allotment is cancelled. Ensure uploaded documents are clear, complete, and match the details in your CUET UG 2026 application exactly.
DU CSAS 2026 Round 1 Seat Allotment FAQs
Ques. What happens if I do not take any action after Round 1 allotment?
Ans. In most rounds, taking no action by the deadline is treated as a Freeze — your allotted seat is retained but you lose upgrade eligibility. Always confirm the exact rule in the official CSAS notice for that round, as it can vary.
Ques. Can I change my decision after clicking Freeze?
Ans. No. Freeze is final and irreversible. Once you click Freeze and pay the admission fee, you exit the CSAS allocation process entirely and cannot participate in Round 2 or Round 3.
Ques. If I choose Accept and Upgrade in Round 1 and do not receive a better allotment in Round 2, what happens?
Ans. Your Round 1 seat is retained. Accept and Upgrade first secures your current allotment and then attempts to improve it. You will not lose the seat simply because no upgrade was available in Round 2.
Ques. When will DU CSAS 2026 Round 1 seat allotment be declared for UG?
Ans. Round 1 UG seat allotment is expected in the third week of July 2026, after CUET UG 2026 results are declared and Phase 2 preference locking is complete. This is based on 2025 patterns; DU will confirm the exact date on ugadmission.uod.ac.in.
Ques. Is document verification done online or at the college?
Ans. Both. You first upload documents online through the CSAS portal for the college to verify digitally. Once verified, you must also carry original documents to the college on the physical reporting date for final confirmation.
Ques. Which documents do I need when reporting physically to my DU college?
Ans. Carry originals and self-attested photocopies of your Class 10 and Class 12 mark sheets, CUET UG 2026 scorecard, CSAS Round 1 allotment letter, category certificate (if applicable), passport-size photographs, a government photo ID, character certificate, and migration certificate if you studied outside the Delhi Board.
