The University of Delhi (DU) has officially launched the CSAS UG Portal 2026 at ugadmission.uod.ac.in, marking the start of undergraduate admissions for the 2026–27 academic session. Registration opened on June 27, 2026, and is open exclusively to candidates who have qualified the CUET UG 2026 examination conducted by the National Testing Agency (NTA).
Unlike the older cut-off based system that relied heavily on Class 12 board percentages, DU now uses the Common Seat Allocation System (CSAS) to allocate all undergraduate seats based on CUET scores alone. For the current cycle, more than 70,000 seats are available across 91 constituent colleges and 79 undergraduate programmes, including BA, BSc, BCom, BTech, BMS, honours, vocational, and professional courses.
If you appeared for CUET UG 2026 and are targeting a seat at Shri Ram college of Commerce (SRCC), Hindu college, Miranda House, or any other DU institution, Phase 1 registration is your first mandatory step. Missing this window means you cannot participate in preference filling or seat allocation later. Read this guide carefully to understand eligibility, fees, timelines, and the complete application workflow.
What Is the DU CSAS UG Portal 2026?
The CSAS UG Portal is Delhi University's centralised online admission platform. It replaced the previous OMR-based and cut-off driven processes that dominated DU admissions before 2022. Today, every general, OBC, SC, ST, EWS, and PwBD seat at the undergraduate level is allocated through this system using CUET normalised scores.
CSAS stands for Common Seat Allocation System. Think of it as a structured counselling engine: you register once, declare your programme preferences in Phase 2, and receive seat allotments in Phase 3 based on your rank, category, and the choices you lock. The portal also handles sports quota, ECA (Extra-Curricular Activities) quota, and special category documentation where applicable.
Key Facts at a Glance
- Official portal: ugadmission.uod.ac.in
- Login credentials: CUET UG 2026 application number and password
- Total colleges: 91 constituent colleges of Delhi University

DU CSAS requires dedicated attention and cannot be substituted by applications elsewhere.
DU CSAS UG 2026 Important Dates
Staying on top of deadlines is critical because DU does not typically reopen missed phases. The dates below are based on the official notification cycle for 2026. Some Phase 2 and Phase 3 dates remain tentative and should be verified on the portal regularly.
| Event | Date |
|---|---|
| CUET UG 2026 Result Declared | June 23, 2026 |
| CSAS Phase 1 Registration Opens | June 27, 2026 |
| Phase 1 Registration Deadline | Mid-July 2026 (Tentative) |
| Phase 2 Preference Filling Begins | Second Week of July 2026 |
| First Seat Allocation List | Third Week of July 2026 |
| Admission Process Concludes | By August 1, 2026 (Tentative) |
Actionable Date Tips
- Do not wait for the last day of Phase 1. Portal traffic spikes near deadlines, and payment gateway failures can cost you valuable time.
- Bookmark the official portal and check the "Notices" section daily during July for updated Phase 2 and allotment schedules.
- Keep your CUET login details ready before starting registration — password recovery during peak hours can be slow.
- Set phone reminders for Phase 2 preference locking, which is a separate and equally critical deadline.
Who Is Eligible for DU CSAS UG 2026?
Eligibility for CSAS is straightforward but has specific conditions that many candidates overlook. Meeting the basic criteria does not automatically mean you can apply to every programme — subject mapping rules apply separately.
Basic Eligibility Criteria
- You must have qualified CUET UG 2026 and hold a valid scorecard.
- You must have passed Class 12 (or equivalent) from a recognised board.
- Your CUET subject combination must match the subject mapping requirements of the programme you wish to apply for.
- You must complete Phase 1 registration, including fee payment and document upload, before the deadline.
Subject Mapping: Why It Matters
Delhi University assigns each undergraduate programme a specific set of required CUET subjects. For example, a BSc (Hons) Physics programme may require you to have appeared in CUET Physics, Mathematics, and a language paper. If your CUET subject combination does not align with the programme's mapping, the portal will not allow you to select that course during preference filling — even if your overall CUET score is high.
Practical tip: Before Phase 2 opens, download the official DU CSAS programme-wise eligibility and subject mapping PDF from the portal. Cross-check every programme on your wish list against the subjects you tested in CUET. This single step prevents wasted preferences and disappointment during seat allocation.
Who Cannot Apply Through CSAS?
- Candidates who did not appear for or qualify in CUET UG 2026.
- Applicants expecting admission based on Class 12 board marks alone — DU discontinued this method for UG admissions in 2022.
- Candidates whose CUET subject combination fails to meet programme-specific requirements.
Understanding the Three Phases of CSAS 2026
The DU admission process is divided into three distinct phases. Each phase builds on the previous one, and skipping or incompletely finishing an earlier phase disqualifies you from the next.
Phase 1: Registration, Documents, and Fee Payment
Phase 1 is currently active. During this phase, candidates log in using their CUET credentials, fill personal and academic details, upload mandatory documents, and pay the CSAS registration fee. This fee is separate from the CUET application fee, is non-refundable, and is paid only once regardless of how many programmes you eventually preference.
Mandatory documents for Phase 1 typically include:
- Class 10 mark sheet (for date of birth verification)
- Class 12 mark sheet or provisional certificate
- Recent passport-size photograph
- Category certificate (SC/ST/OBC-NCL/EWS/PwBD), if applicable
- Additional certificates for sports or ECA quota, if claiming those seats
Phase 2: Preference Filling and Locking
Once Phase 1 is complete, eligible candidates gain access to the preference filling module. Here you rank college programme combinations in order of priority. For instance, you might list "BA (Hons) Economics at SRCC" as preference 1, "BA (Hons) Economics at Hindu college " as preference 2, and so on.
Critical rule: Preferences must be locked before the Phase 2 deadline. Unlocked or draft preferences are not considered for seat allocation. You can typically reorder preferences before locking, but once locked, changes may not be permitted — treat your locked list as final.
Phase 3: Seat Allocation, Acceptance, and Admission
DU releases seat allocation lists in multiple rounds during Phase 3. When you receive an allotment, you must accept the seat, pay the admission fee, and complete document verification within the stipulated window. Failure to accept within the deadline results in forfeiture of that allotment, and you may be considered in subsequent rounds depending on vacancy and your remaining preferences.
The process concludes tentatively by August 1, 2026, though exact dates depend on how many allocation rounds are required to fill all seats.
DU CSAS UG 2026 Registration Fee Structure
The CSAS registration fee is modest but mandatory. It must be paid online — offline or cash payments are not accepted under any circumstance.
| Category | Registration Fee |
|---|---|
| General / OBC-NCL / EWS | Rs 250 |
| SC / ST / PwBD | Rs 100 |
| BFA Programme (Additional Charge) | Rs 400 |
| Sports / ECA Quota (Additional Charge) | Rs 100 |
Payment Modes and Tips
Accepted payment methods include UPI, net banking, debit card, and credit card. Keep the transaction receipt and registration confirmation page saved as PDFs. If your payment is debited but the portal does not reflect confirmation, do not pay again immediately — note the transaction ID and contact the CSAS helpdesk with proof of payment.
Candidates applying for the Bachelor of Fine Arts (BFA) programme must pay an additional Rs 400 beyond the standard registration fee. Similarly, sports and ECA quota applicants pay an extra Rs 100. These charges are in addition to, not in place of, the base category fee.
Programmes and Colleges Covered Under CSAS 2026
CSAS covers the full spectrum of Delhi University's undergraduate offerings. Popular programmes include BA (Hons) in English, Political Science, and Economics; BSc (Hons) in Physics, Chemistry, and Mathematics; BCom (Hons); BTech; BMS; BBE; and vocational courses under the School of Open Learning framework where applicable.
How to Build a Smart Preference List
Many students make the mistake of listing only top-tier colleges. While ambition is healthy, your preference list should reflect a realistic spread:
- Dream choices (3–5): Colleges where your CUET score is competitive but admission is not guaranteed.
- Target choices (5–8): Colleges where your score aligns well with previous year trends.
- Safe choices (5–10): Colleges and programmes where admission is highly likely based on your rank.
Remember that DU allocates seats based on your highest available preference you qualify for not simply the college with the lowest cut-off. Ordering matters enormously.
CSAS vs Other Admission Routes: What Students Should Know
CUET UG is now the gateway to central universities, many state universities, and numerous private institutions across India. However, each university runs its own counselling portal with separate timelines and rules.
Students from cities like Kota — a well-known coaching hub — often weigh DU against local options such as MD Mission College Kota or distance-learning pathways through Vardhman Mahaveer Open University Kota. The key difference is that DU CSAS is entirely CUET-score driven with no board percentage weightage, while other institutions may follow their own merit formulas.
Similarly, students interested in design programmes should note that admissions like NID DAT follow a completely separate exam and counselling process unrelated to CUET or CSAS. Managing multiple admission tracks in parallel is common during June and July — maintain a spreadsheet with portal links, deadlines, and fee amounts for each application.
Background: How DU Admissions Changed After 2022
Before 2022, Delhi University published multiple cut-off lists based on Class 12 board marks. Students rushed to secure admissions as cut-offs dropped across rounds, and the process was often unpredictable. Since adopting CUET and CSAS, the system has become more standardised and transparent.
Class 12 marks now serve only as an eligibility requirement — you must have passed — but they do not influence your merit rank. Your CUET normalised score, category, and preference order determine your seat. This shift aligns DU with other central universities that use CUET as a common entrance test, reducing the burden of appearing for dozens of separate college entrance exams.
Common Mistakes to Avoid During CSAS Registration
- Uploading blurry or incorrectly formatted documents — use clear scans in JPG or PDF format as specified on the portal.
- Entering mismatched name spellings — your CSAS profile name must match your Class 10 certificate and CUET application exactly.
- Ignoring category certificate validity — OBC-NCL and EWS certificates must meet current year income and caste validity norms.
- Paying the fee but not completing the form — fee payment alone does not confirm registration; all steps must show "Completed" status.
- Listing preferences randomly in Phase 2 — you may receive a seat at a lower-priority college even if a higher-ranked college had vacancy later.
- Missing the seat acceptance deadline in Phase 3 — allotments expire if not accepted within the given window.
Document Checklist Before You Start Phase 1
Gather these documents before logging in to avoid session timeouts:
- CUET UG 2026 application number and password
- CUET UG 2026 scorecard (download from the NTA portal)
- Class 10 mark sheet for date of birth proof
- Class 12 mark sheet or provisional pass certificate
- Recent passport-size photograph (white background, specified dimensions)
- Valid photo ID (Aadhaar, passport, or school ID)
- Category certificate in the candidate's name, if applicable
- Income certificate for EWS candidates
- Disability certificate for PwBD candidates, issued by competent authority
- Sports/ECA achievement certificates, if applying under quota seats
What Happens After Phase 1 Registration?
Once Phase 1 is successfully completed, your dashboard will show a confirmation status. You will then wait for Phase 2 to open in the second week of July 2026. During the waiting period, research colleges thoroughly — visit campus websites, review faculty profiles, check placement records for professional programmes, and speak with current students if possible.
When Phase 2 opens, log in promptly, build your preference list using the tiered strategy described above, review it at least twice, and lock it before the deadline. After locking, monitor the portal for Phase 3 seat allocation announcements. The first allocation list is expected in the third week of July 2026.
Sports and ECA Quota Seats: Additional Requirements
Delhi University reserves a percentage of seats under the sports quota and ECA (Extra-Curricular Activities) quota. Candidates claiming these seats must pay an additional Rs 100 during Phase 1 registration and upload certificates proving achievements at the state, national, or international level as specified in the official notification.
Sports quota applicants typically undergo trials or certificate verification after CSAS registration. ECA candidates may face auditions or portfolio reviews depending on the activity category — music, dance, debate, theatre, and fine arts each have distinct evaluation criteria published on the portal. Even with a strong sports or ECA profile, your CUET score still plays a role in merit ranking within the quota category, so do not treat quota seats as a bypass of academic requirements.
BFA Programme: Special Admission Note
The Bachelor of Fine Arts (BFA) programme carries an additional registration charge of Rs 400 on top of the standard CSAS fee. BFA applicants may also need to appear for a practical test or submit a portfolio as part of the admission process. Check the Faculty of Music and Fine Arts section on the portal for updated instructions specific to the 2026 cycle.
Helpline and Support During CSAS 2026
If you encounter technical issues — login failures, payment errors, or document upload rejections — use the official helpdesk contact details listed on ugadmission.uod.ac.in. When raising a query, always mention your CUET application number, registered email, and a screenshot of the error. Avoid sharing OTPs or passwords with anyone claiming to be a DU admission agent; all registration must be completed personally by the candidate on the official portal.
Conclusion
The DU CSAS UG Portal 2026 is now live at ugadmission.uod.ac.in, and Phase 1 registration is the essential first step for every CUET-qualified candidate seeking a Delhi University seat. With over 70,000 seats across 91 colleges and 79 programmes, the opportunity is significant — but so is the competition.
Focus on completing Phase 1 accurately and on time, verify your subject mapping before Phase 2, and build a balanced preference list that reflects both your aspirations and your CUET score realistically. Keep checking the official portal for updated notices, save every payment receipt, and avoid last-minute rushes that lead to preventable errors.
Delhi University remains one of India's most sought-after destinations for undergraduate education. A methodical approach to CSAS register, preference, allocate, accept gives you the best chance of securing a seat at the college and programme you have worked hard to reach.
