DU Phase 2 Admission 2026 has officially opened at the University of Delhi’s Common Seat Allocation System (CSAS-UG) portal, marking the stage where candidates who cleared CUET UG 2026 move from basic registration into the real decision-making part of the admission process. Running from July 3 to July 11, 2026, this phase requires candidates to map their Class 12 subjects against their CUET papers and lock in their programme and college preferences across Delhi University’s constituent colleges. With 82,940 candidates already registered through Phase 1 and the first CSAS seat allocation list scheduled for July 16, 2026, at 5 PM.
Because DU’s CSAS system locks preferences automatically once each window closes, DU Phase 2 Admission 2026 is widely considered the most consequential stage of the entire process, the choices you save here directly determine which programme-college combination you’re offered on July 16. This year, Delhi University is offering admission to 73 undergraduate programmes and 150 BA Programme combinations, with every programme-college pairing treated as an entirely separate, individually rankable preference.
What Is DU CSAS-UG and Why Does Phase 2 Matter?
The Common Seat Allocation System (CSAS-UG) is Delhi University’s centralized, CUET-score-based admission platform, introduced after the Common University Entrance Test became the standard national entry route for central universities. The process unfolds across three broad stages: Phase 1 (registration and fee payment), Phase 2 (subject mapping and preference filling), and the seat allocation and admission rounds that follow.
While Phase 1 simply confirms your eligibility to participate, Phase 2 is where actual college and course choices are made and locked — meaning a missed deadline or an unsaved preference in this stage can genuinely cost you a seat at a preferred college, even if your CUET score was strong enough to qualify.

Eligibility to Participate in DU Phase 2 Admission 2026
Only candidates who have already completed Phase 1 registration and paid the applicable fee are eligible to proceed to Phase 2. Delhi University has been explicit that Phase 2 participation is strictly conditional on Phase 1 completion — there is no way to skip directly to subject mapping and preference filling without first finishing registration. If you missed Phase 1, check the official portal immediately for any extension notice, since both Phase 1 and Phase 2 windows are scheduled to close simultaneously on July 11.
How to Complete DU CSAS Phase 2 Registration
- Visit the official portal at admission.uod.ac.in — using a desktop browser is recommended, since mobile browsers may not display all preference options clearly.
- Log in using the same CUET UG 2026 application number and password created during Phase 1.
- Verify your profile details — confirm your name, category, CUET application number, and Class 12 board details exactly match your official documents.
- Map your Class 12 subjects with your CUET UG 2026 papers. For each subject studied in Class 12, select the corresponding CUET paper you actually appeared for. This step is compulsory and directly determines your eligibility for specific programmes — DU strictly enforces that candidates can only be considered for programmes matching subjects they cleared in Class 12 and attempted in CUET.
- Select eligible programme-college combinations. Because DU treats every programme-college pairing as a distinct, separately ranked preference — for example, B.A. (Hons) English at one college is a completely separate choice from the same programme at another college — add as many eligible combinations as you’re genuinely willing to accept.
- Arrange your preferences in true order of priority, using the portal’s Top, Bottom, and Preference Number reordering tools.
- Save your preferences regularly. Only saved choices are considered during seat allocation — the university has explicitly warned that unsaved edits will not carry over.
- Preview all choices carefully before the deadline, then submit your final application before 11:59 PM on July 11, 2026, and download the confirmation page for your records.
DU CSAS UG 2026 Application Fee Structure
| Category | Application Fee |
|---|---|
| UR / OBC-NCL / EWS | ₹250 |
| SC / ST / PwBD | ₹100 |
| Additional fee for BFA, B.A. (Hons.) Music, and B.Sc. (specific programmes) | ₹400 per programme (extra) |
Understanding Simulated Ranks Before Final Allocation
Before the first official seat allocation list, DU publishes simulated ranks on July 12, 2026, at 5 PM. This gives candidates a data-driven estimate of their likely position for each preference they’ve saved, based on their CUET score and the preferences submitted by all other candidates. The narrow 24-hour Preference Change Window that follows (July 12, 5 PM to July 13, 4:59 PM) is specifically designed to let candidates reorder or revise their choices strategically based on this simulated data — a meaningful opportunity that candidates shouldn’t skip, since it’s the last chance to adjust preferences before the binding first allocation round.
How DU Seat Allocation and the Upgrade System Work
Once the first allocation list is published on July 16, 2026, candidates allotted a seat have three options:
- Accept the seat as allotted.
- Upgrade, keeping the current seat as a fallback while remaining eligible for a higher-ranked preference in the next round — if upgraded, the previous seat is automatically cancelled in favor of the new one.
- Freeze, which locks in the current seat and formally opts the candidate out of any further upgrade opportunities in subsequent rounds.
Candidates who are upgraded must actively accept and complete admission procedures for their new seat — failing to act on an upgraded seat results in cancellation and exclusion from the CSAS-UG 2026 process altogether. Inactivity after accepting a seat, by contrast, simply means the current seat is retained without further upgrades.
Documents Required for DU CSAS UG 2026
Keep the following ready before and during the registration process:
- CUET (UG) 2026 Application Number
- Class 10 and Class 12 marksheets
- Category or reservation certificate (if applicable)
- Passport-size photograph and scanned signature
- Valid government-issued photo ID
- Sports/ECA or other programme-specific certificates, where relevant
Delhi University has also introduced API Setu-based auto-integration, which automatically fetches candidate details like name, date of birth, photograph, and signature using the CUET UG 2026 application number — reducing manual data-entry errors and strengthening the security of the admission process.
Programme and College Range Under CSAS-UG 2026
This year, CSAS-UG facilitates admission to 73 undergraduate programmes and 150 BA Programme combinations across Delhi University’s constituent colleges, spanning disciplines including:
- Humanities and Social Sciences — B.A. (Hons) in English, History, Political Science, Economics, Psychology, Sociology, and related disciplines
- Commerce and Management — B.Com (Hons), BMS, BBA-FIA, and related programmes, several of which now place greater weightage on CUET’s General Test and Mathematics paper for eligibility
- Science programmes — B.Sc. (Hons) across multiple disciplines
Because seat availability is published college-wise and category-wise directly on the portal, candidates are encouraged to review the actual seat matrix for their target programmes before finalizing their preference order, rather than relying solely on previous years’ cutoff trends.
Common Mistakes to Avoid During DU Phase 2 Admission 2026
- Arranging preferences carelessly — since the order directly determines your allocation outcome, treat preference ranking as a strategic decision, not an afterthought.
- Missing the preference-locking deadline — no changes are possible once a window auto-locks, regardless of the reason for the delay.
- Not checking the dashboard regularly — all official communications from DU are made exclusively through the CSAS dashboard and your registered email, not through third-party alerts.
- Failing to act on an allotted or upgraded seat within the deadline — inactivity at the wrong stage can result in losing a seat you were otherwise eligible for.
- Mismatched subject mapping — selecting a CUET paper that doesn’t correspond to a genuinely studied and cleared Class 12 subject can render you ineligible for that specific programme, even if your overall CUET score would otherwise qualify.
What Happens After the Second Allocation Round?
Following the second seat allocation list on July 25, 2026, candidates admitted in that round can reorder their preferences until July 28, 2026. Delhi University has indicated that additional allocation rounds may follow if seats remain vacant after the first two rounds, though the detailed schedule for those later rounds is typically announced closer to the time. Candidates should continue monitoring the official CSAS portal throughout the admission cycle rather than assuming the process concludes after the second round.
