The DU CSAS Portal 2026 (Common Seat Allocation System) is the official online platform through which the University of Delhi (UoD) will administer DU UG admissions for the academic session 2026-27. All UG admissions across DU's 91 constituent colleges are conducted exclusively through this portal, based on CUET-UG 2026 scores. Students must not only clear the CUET-UG 2026 examination but also complete all mandatory phases of the DU CSAS portal within the deadlines to secure a seat.
For the 2025-26 session, DU offered 79 UG programs across 91 colleges. For 2026-27, the structure is expected to remain largely the same. The CUET-UG 2026 registration opened on January 3, 2026, with the exam scheduled from May 11 to May 31, 2026. The DU CSAS Portal 2026 is expected to go live in June 2026, after the CUET exam is over.
The DU CSAS (Common Seat Allocation System) is a web-based, centralised admission platform created by the University of Delhi. It replaced the older cut-off-based system and introduced a transparent, merit-driven process based exclusively on CUET-UG scores. Through the CSAS portal, students can:
The CSAS process is divided into three distinct phases, each with clearly defined deadlines. Failure to complete any phase within the stipulated time will result in disqualification from the admission process.

The DU CSAS portal registration is a completely online process. There is no provision for offline or physical submission of applications. The steps below are based on the established CSAS process and are expected to remain the same for 2026.
The Step-by-Step DU CSAS Registration Process is Explained Below.
Step 1: Visit the official DU CSAS portal at ugadmission.uod.ac.in.
Step 2: Click on the "New Registration" tab on the homepage.
Step 3: Enter your CUET-UG 2026 Application Number and Date of Birth. The system will auto-fetch your personal and academic details from the CUET database.
Step 4: Verify all auto-fetched details carefully. Upload required documents, including category certificates (if applicable), photograph, and signature.
Step 5: Pay the applicable CSAS registration fee online through the payment gateway (credit card, debit card, net banking, or UPI).
Step 6: Save your login credentials (application number/email and password). Registration is complete once payment is confirmed.
Step 1: Log in to the CSAS portal once Phase II opens.
Step 2: Map your CUET 2026 test papers with your Class 12 subjects as required by the programme. DU strictly enforces subject mapping in 2026 - only subjects studied in Class 12 are valid.
Step 3: Verify your programme-specific eligibility using the mapped subjects and CUET scores.
Step 4: Select your preferred programmes and colleges. You may select multiple combinations and arrange them in order of preference. You can select hundreds of preferences - arrange them from most wanted to least wanted.
Step 5: Review your preference order carefully. Save and lock your preferences before the deadline. The system will auto-lock your most recently saved preferences at the deadline if no manual action is taken.
Important: No changes can be made to preferences once the final locking deadline has passed. A short preference re-ordering window will be provided after Simulated Ranks are declared. Use this window carefully to adjust your preferences based on your tentative rank.
Step 1: Log in to your CSAS dashboard after the seat allocation list is announced.
Step 2: Check your allotted college and program. If satisfied, click "Accept" within the stipulated deadline.
Step 3: If you prefer a higher-preference option, opt for an upgrade where available. Candidates who select upgradation will have their current seat cancelled if a new one is allocated.
Step 4: Once satisfied with an allocation, submit a "Freeze" request to opt out of further upgrades and confirm your seat.
Step 5: The concerned college will verify and approve your application within the specified timeline.
Step 6: Pay the admission fee online within the deadline to secure your seat. Non-payment within the deadline results in cancellation of the allotment.
Note: Inactivity after a seat is allotted - that is, neither accepting nor upgrading - will result in the seat being retained without eligibility for future upgrades. Always take action on your dashboard within the given deadline.
Simulated Ranks are tentative, indicative ranks released by DU before the first official seat allocation list is published. They are generated based on students' CUET-UG 2026 scores, the program-college preferences submitted, category, and seat availability. Simulated Ranks are retained as a key feature in the CSAS 2026 process.
Simulated Ranks help students understand where they are likely to stand in the merit order for each of their selected preferences. After these ranks are declared, students are given a short window (typically 1-2 days) to re-order their preferences. Students should use simulated ranks as a strategic planning tool - not as a guaranteed outcome- and make thoughtful revisions to their preference order during the window provided.
The DU CSAS merit list will be generated entirely based on CUET-UG 2026 scores and published separately for each program-college combination. Cut-off marks will vary by program, college, and category. All cut-off and merit list information will be available only on the individual candidate dashboards on the CSAS portal - DU does not publish a single, generalised cut-off list.
In the event of a tie, DU uses the following tie-breaking hierarchy for 2026:
Students are advised to:
Documents Required for DU CSAS Portal Registration 2026
Students must keep the following documents ready in scanned/digital format before beginning the DU CSAS registration process:
The DU CSAS (Common Seat Allocation System) portal at ugadmission.uod.ac.in is the official online platform through which the University of Delhi manages all UG admissions. It works in three phases - registration, preference filling, and seat allocation - based entirely on a candidate's CUET-UG score.
Visit ugadmission.uod.ac.in, click "New Registration," enter your CUET application number and date of birth, verify auto-fetched details, upload required documents, and pay the non-refundable registration fee. Registration is complete once payment is confirmed.
There are three phases - Phase I (Registration), Phase II (Subject mapping and course/college preference filling), and Phase III (Seat allocation, acceptance, and fee payment). All three must be completed within their respective deadlines.
Yes. CUET-UG is the sole eligibility criterion for DU UG admission. Without a valid CUET-UG scorecard, a candidate cannot register on the DU CSAS portal or be considered for any seat allocation round.
CUET-UG application number, Class 10 and Class 12 marksheets, category certificate (if applicable), passport-size photograph, scanned signature, valid government-issued ID proof, and sports/ECA certificates if applying under the supernumerary quota.
Rs. 250 for UR/OBC-NCL/EWS candidates and Rs. 100 for SC/ST/PwBD candidates. An additional Rs. 400 is charged for BFA/B.Sc (PE, HE & S)/B.A. (H) Music applicants, and Rs. 100 per quota for ECA/Sports supernumerary seats. All fees are non-refundable.
Yes, but only within the correction window announced by DU - typically a few days before Phase II closes. Outside this window, submitted details cannot be modified. Preferences, however, can be re-ordered during the short window provided after Simulated Ranks are declared.
Log in during Phase II, map your CUET papers to your Class 12 subjects, check your programme-specific eligibility, then use the portal's search tool to select course-college combinations. Arrange all selections in your desired priority order before saving and locking.
There is no fixed upper limit. Candidates can fill as many course-college combinations as they are eligible for. DU recommends filling the maximum possible preferences to maximise the chances of getting a seat.
List your most desired programme-college combination first and work downward to safer options. Do not leave any eligible combination out - more preferences mean better chances. Use Simulated Ranks to reassess and re-order before the final lock.
After preferences are locked, DU runs an algorithm that matches candidates to seats based on CUET score, category, and preference order. The highest preference for which a candidate qualifies is allocated. Multiple rounds are conducted to fill vacant seats.
Simulated Ranks are tentative, indicative ranks released before the first allocation list to help candidates re-order preferences strategically. Actual allocation is the final confirmed seat assigned during an official allocation round, which candidates must accept within the given deadline.
Candidates must log in to their dashboard, accept the allotted seat, wait for the college to verify and approve the application, and then pay the admission fee online within the stipulated deadline. Non-payment leads to cancellation of the allotment.
Candidates who are not allocated a seat in Round 1 are automatically considered for subsequent allocation rounds based on their saved preferences. No separate action is needed - candidates simply need to monitor their dashboard.
Yes. After accepting a seat in Round 1, candidates can opt for upgradation if they wish to be considered for a higher preference in the next round. If a better seat is allocated in Round 2, the previously held seat is automatically released.
Auto-upgrade means the system will automatically consider the candidate for a better preference in the next round if they do not take any action after accepting a seat. Auto-freeze means the candidate opts to retain the current allotment and withdraw from further rounds. Candidates should actively choose one option on their dashboard within the deadline.
Yes. Candidates can withdraw their admission through the CSAS portal. However, the refund policy is governed by UGC guidelines - a full or partial refund depends on when the withdrawal is initiated relative to the start of the academic session.
No. Preferences cannot be changed after the final locking deadline. However, candidates who accepted a seat in Round 1 can opt for upgradation, which considers their already-saved higher preferences in subsequent rounds. The preference order itself cannot be edited after the lock.
