DU Admission 2026: For hundreds of thousands of Class 12 graduates across India, one online portal now stands between them and a seat at one of the country’s most prestigious public universities. Delhi University’s Common Seat Allocation System (CSAS) the centralized gateway for undergraduate admission across all 91 constituent colleges opened its counselling registration on June 17, 2026, officially kicking off the 2026-27 admission cycle. With more than 70,000 UG seats on offer and registration running through June 30, this guide walks through exactly what students need to know: dates, fees, eligibility rules, the seat matrix, and the complete step-by-step process.
DU CSAS Portal
The Common Seat Allocation System (CSAS) is the official, centralized online platform through which the University of Delhi (DU) administers every undergraduate admission decision. Unlike the older system of applying separately to individual colleges, all UG admissions now flow exclusively through this single portal, accessible at admission.uod.ac.in. Crucially, admission is based entirely on a candidate’s CUET-UG 2026 scorecard DU no longer considers Class 12 board marks as a primary factor in seat allocation, except in specific tie-breaking situations described later in this guide. For the 2026-27 academic session, the university is expected to continue offering 79 UG programs across its 91 constituent colleges, broadly mirroring the structure from the previous admission cycle.
DU CSAS 2026 Key Dates
The DU CSAS counselling process for 2026 follows a clear, phase-based structure. While exact downstream dates remain subject to official confirmation, the following milestones have already been locked in or strongly indicated:
| Milestone | Date / Status |
|---|---|
| CUET-UG 2026 registration opened | January 3, 2026 |
| UG Bulletin of Information 2026-27 released | January 6, 2026 |
| CUET-UG 2026 examination window | May 11 to May 31, 2026 |
| CSAS Phase 1 (registration) opens | June 17, 2026 |
| Last date to apply (Phase 1) | June 30, 2026 |
| Phase 2 (choice/preference filling) | Opens after CUET-UG results are declared |
| Phase 3 (seat allocation & admission) | Multiple rounds, followed by spot rounds if seats remain vacant |
| Entire admission process expected to conclude | By August 1, 2026 |
Students should treat any dates beyond Phase 1 as provisional until DU issues further official notifications directly on the CSAS portal, since downstream timing depends heavily on when CUET-UG 2026 results are finally declared.
DU CSAS Registration Fees
One of the most common points of confusion for first-time applicants is understanding that the CSAS registration fee is entirely separate from the CUET-UG application fee paid earlier to the National Testing Agency (NTA). The Phase 1 CSAS fee structure for 2026 is:
| Category | Phase 1 Registration Fee |
|---|---|
| General, OBC-NCL, EWS | ₹250 |
| SC, ST, PwBD | ₹100 |
| Seat cancellation fee (if applicable) | ₹1,000 |
This registration fee is a one-time, non-refundable payment, distinct from the college admission fee that gets paid later, after a seat has actually been allotted in Phase 3. Payment can only be made online — through debit card, credit card, net banking, or UPI with no cash or offline payment option available at any stage of the CSAS process.
Eligibility Criteria for DU UG Admission 2026
To qualify for Delhi University’s undergraduate programs, candidates must satisfy the following baseline requirements:
- Completion of Class 12 (or equivalent) from a recognized board
- Mandatory appearance in CUET-UG 2026, specifically in the subjects the candidate studied and passed in Class 12
- If a Class 12 subject isn’t offered directly within CUET, candidates must appear in a similar or related subject instead
- No upper age limit applies to UG admissions, except where a specific regulatory body imposes one for a particular professional program
- Gap-year candidates remain fully eligible, provided they appear in CUET-UG 2026
Strict Subject Mapping Enforcement
A particularly important update for 2026 involves subject mapping. DU is strictly enforcing the rule that candidates may only select CUET papers corresponding to subjects they actually studied and cleared in Class 12. Choosing an invalid subject combination one that doesn’t align with a candidate’s actual academic background will result in that combination being rejected outright during the eligibility verification process.
Revised Weightage for Management Programs
Students targeting management-focused programs should pay close attention to a specific 2026 change: programs like BMS (Bachelor of Management Studies) and BBA-FIA now place higher weightage on the General Test and Mathematics component within the CUET score, compared to how these programs were evaluated in previous cycles.
The DU Seat Matrix: How Many Seats Are Actually Available?
For 2026-27, Delhi University is expected to offer approximately 70,000 undergraduate seats across its 91 constituent colleges, spanning a wide academic range including:
- Humanities and Languages
- Sciences
- Commerce
- Management Studies
- Vocational Studies
- Music and Fine Arts
- Education
Among the most sought-after programs are BA (Hons), BSc (Hons), BA (Programme), BCom (Hons), and BMS consistently drawing the highest application volumes and, correspondingly, the most competitive cutoffs each year.
Reservation Policy
Seats are distributed category-wise, following Government of India reservation norms for SC, ST, OBC-NCL, EWS, and PwBD candidates. Importantly, because DU is a central university, there is no home-state quota or domicile-based reservation for any program candidates from anywhere in India compete on equal footing within their respective category.
How to Complete DU CSAS Registration 2026?
Step 1: Visit the Official Portal and Begin Registration
Navigate to admission.uod.ac.in and select “New Registration.” Enter your CUET-UG 2026 Application Number, Roll Number, and Date of Birth exactly as they appear on your CUET documentation.
Step 2: Create Your Login Credentials
Set a secure password for your CSAS account. Once created, the system will auto-fetch much of your personal and academic information directly from the CUET database, significantly reducing manual data entry.
Step 3: Verify Auto-Fetched Details Carefully
This step is critical: candidates must carefully verify every auto-fetched field before proceeding. Errors in auto-populated personal or academic information are a commonly cited mistake that can complicate or delay an application later in the process.
Step 4: Upload Required Documents
Keep the following ready in scanned digital format before beginning registration:
- Class 10 and Class 12 mark sheets and certificates
- Category certificates (SC/ST/OBC-NCL/EWS/PwBD), where applicable
- A valid photo ID
- Passport-sized photograph and signature (note: these specific fields are auto-integrated from your CUET form and cannot be edited during CSAS registration)
Step 5: Pay the Registration Fee
Complete payment through the designated online payment link within the portal. Registration is not considered complete until fee payment is confirmed simply filling out the form without completing payment leaves your application incomplete.
Step 6: Download Your Confirmation Page
Once registration is finalized, download and save the confirmation page for future reference, and check your registered email (including the spam folder) for a system-generated confirmation message.
Choice Filling and Seat Allocation
Once CUET-UG 2026 results are declared, candidates move into Phase 2 (preference filling). Here, students select as many eligible college-and-program combinations as possible, ranked in order of priority — DU explicitly advises filling more preferences to meaningfully improve allotment chances.
Simulated Ranks: A Strategic Planning Tool
Before the first official seat allocation list is published, DU releases Simulated Ranks tentative, indicative rankings generated from a candidate’s CUET-UG 2026 score, submitted preferences, category, and seat availability. These ranks give students a realistic preview of where they’re likely to stand for each chosen preference, allowing for strategic re-ordering of preferences before they’re locked in.
Seat Allocation Rounds and the Freeze/Upgrade/Reject Decision
Once seats are allotted, candidates choose between three options on their dashboard:
- Freeze — Accept the allotted seat and exit the upgrade process
- Upgrade — Accept the current seat while remaining eligible for a better one in subsequent rounds
- Reject — Decline the seat and continue participating in later rounds, if eligible
Important: if a candidate takes no action neither accepting nor upgrading within the given deadline, the seat is automatically retained without eligibility for future upgrades, effectively locking the candidate into that allocation by default.
Tie-Breaking Rule
In the event that two or more candidates have identical CUET scores for the same program-and-college combination, DU applies a clear tie-breaking formula: Class 12 Board marks are used as the deciding factor, calculated first as the best of 3 subjects, then best of 4, and finally best of 5, if a tie still persists.
Spot Rounds for Remaining Vacancies
If seats remain vacant after the regular allocation rounds conclude, DU conducts additional Spot Rounds generally up to two specifically to fill remaining vacancies in select programs and colleges. Candidates must apply separately for spot round participation, and allotments in this stage are typically final, with little to no upgrade flexibility once allotted.
The DU CSAS 2026 admission cycle represents one of India’s largest and most closely watched centralized university admission processes, now fully underway with Phase 1 registration open through June 30. With over 70,000 seats at stake across 91 constituent colleges, success in this process depends on far more than simply clearing CUET-UG 2026 it requires careful attention to registration deadlines, accurate documentation, strategic preference ordering, and prompt action at every allocation round. Staying closely connected to the official CSAS portal throughout the coming weeks remains the single most reliable way to navigate this process successfully.
