DU CSAS 2026 counselling is the single most important step between your CUET UG 2026 scorecard and a Delhi University seat. With the CUET UG 2026 result declared by the NTA on 23 June 2026, lakhs of students are now racing to understand the DU CSAS 2026 admission process — registration, preference filling, seat allotment and spot rounds. This complete guide walks you through every phase of the Common Seat Allocation System (CSAS) so you do not lose a seat to a missed deadline or a badly ordered preference list.
Quick status (as of publication): CUET UG 2026 result is OUT (23 June 2026). DU CSAS Phase 1 registration opened on 17 June 2026 at admission.uod.ac.in. Phase 2 (preference filling) opens after the result — expected in the first week of July 2026. Always confirm live dates on the official portal.
What is DU CSAS 2026?
The Common Seat Allocation System (CSAS) is Delhi University’s centralised, fully online admission engine for undergraduate programmes. Admission to all DU colleges is based purely on your CUET UG 2026 score plus the college-and-programme preferences you submit. There is no separate DU entrance test and no college-by-college application — one CSAS profile feeds every college you are eligible for.
For the 2026 cycle, DU is offering over 71,000 undergraduate seats across nearly 79 academic programmes in 70+ affiliated colleges. A total of 11,64,098 candidates appeared for CUET UG 2026 (out of 15,68,867 registered), so competition for the top colleges will be intense — and your CSAS strategy matters as much as your raw score.
The three phases of DU CSAS 2026
CSAS is conducted in three clearly defined phases. Understanding each one is the difference between a confident admission and a panicked scramble.
Phase 1 — Application to the University
This is the one-time CSAS registration. You create your DU profile, enter your CUET application number, academic and personal details, category, and upload documents. The Phase 1 fee for the 2026 cycle is ₹250 for UR/OBC-NCL/EWS and ₹100 for SC/ST/PwBD candidates. Phase 1 opened on 17 June 2026 and you can complete profile creation, document upload and fee payment right now — you do not need to wait for the result for this step.
Phase 2 — Preference filling (the make-or-break step)
Phase 2 begins after the CUET UG 2026 result is declared, expected in the first week of July 2026. Here you select college-and-programme combinations and order them by preference. The order you choose IS the order of allotment — CSAS allots you the highest-ranked preference for which your score qualifies. Fill the maximum number of valid preferences and place dream colleges higher, safe colleges lower. A short, over-confident preference list is the most common reason strong scorers end up with no seat in the early rounds.
Phase 3 — Seat Allotment-cum-Admission & Spot Rounds
DU runs multiple regular CSAS Allocation-cum-Admission rounds followed by Spot Admission rounds for any vacant seats. In each regular round you can accept a seat, upgrade to a higher preference in a later round, or withdraw. Note: in Spot Admission rounds there is no Upgrade and no Withdraw option — once you accept a spot seat, it is final. Pay the seat-acceptance fee within the deadline of each round or your allotment lapses.

How to register for DU CSAS 2026: step by step
- Visit the official DU admission portal at admission.uod.ac.in (also ugadmission.uod.ac.in).
- Click “New Registration” and create your account using your CUET UG 2026 application number.
- Fill personal, academic, category and special-quota details accurately.
- Upload scanned documents (photo, signature, Class 10/12 certificates, category and ECA/sports certificates if applicable).
- Pay the Phase 1 registration fee (₹250 / ₹100).
- Wait for Phase 2 to open after the result, then fill your college-programme preferences carefully and lock them.
- Track every allotment round and accept/upgrade/pay within the deadline.
Smart preference-filling strategy
- Fill ALL valid preferences. More preferences = more chances to be allotted a seat in early rounds.
- Order by genuine preference, not by cut-off. CSAS always tries to give you your highest qualifying choice, so dream colleges go at the top.
- Mix dream, target and safe colleges. A balanced list protects you from going unallotted.
- Re-check eligibility for every programme (subject mapping, language requirements) before locking.
- Use the “upgrade” option strategically in regular rounds to climb toward a better college without losing your current seat.
