Before registering on the DU CSAS portal 2026, students must ensure they meet the following eligibility requirements. The basic eligibility criteria are as follows:
Students must verify detailed program-wise eligibility before filling preferences in Phase II.

The DU CSAS portal registration is a completely online process. There is no provision for offline or physical submission of applications. The phase-wise detailed DU CSAS 2026 process are explained below.
Phase I is the registration stage of the DU CSAS (UG) admission process. Every candidate seeking admission to any undergraduate program at the University of Delhi must complete this phase using their CUET (UG) 2026 Application Number.
During registration, the portal automatically imports key details such as the candidate's name, category, date of birth, photograph, signature, mobile number, and email ID from the CUET database. These details cannot be edited, so students must ensure that their CUET application information is accurate before registering.
Candidates are also required to upload supporting documents, enter academic details carefully, apply for any supernumerary quotas (if applicable), and pay the prescribed registration fee. Incomplete registration or non-payment of the application fee will result in the application not being considered for admission.
Steps to Complete Phase I
In this DU CSAS 2026 phase, candidates must map their CUET subjects with the subjects studied in Class XII and fill their program and college preferences. The University calculates programme-specific eligibility based on the candidate's CUET subject combination and displays all eligible program-college combinations.
Candidates can choose as many valid preferences as they wish and arrange them in the exact order of priority. Since seat allocation is entirely based on merit and preference order, students should carefully plan their choices.
After the simulated ranks are released on DU CSAS portal 2026, the university provides a one-time opportunity to reorder preferences before they are finally locked. However, no new preferences can be added or deleted after the preference-filling window closes.
Steps to Complete Phase II
Phase III is the final admission stage of DU CSAS portal, where seats are allocated based on CUET scores, program-specific merit, category, seat availability, and the candidate's preference order. Once a seat is allotted, candidates must accept it within the specified deadline.
The allotted college then verifies the uploaded documents and eligibility. After successful verification, candidates must pay the admission fee online to confirm their admission. Eligible candidates may choose the Upgrade option to be considered for a higher preference in subsequent rounds or Freeze their current seat if satisfied.
Failure to accept the allotted seat or pay the admission fee within the prescribed timeline through the DU CSAS portal will lead to cancellation of the allotment.
Steps to Complete Phase III
Note: Complete every action within the specified timelines, as missed deadlines may lead to cancellation of admission and loss of eligibility for subsequent rounds.
The University of Delhi charges a one-time, non-refundable DU CSAS (UG) application fee that must be paid online during Phase I of registration. Your application is considered complete only after the successful realization of the application fee. Candidates must make the payment only through the official payment gateway available on the DU CSAS portal.

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 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 (July 12 & 13) 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 DU CSAS portal correction window.
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 DU CSAS portal.
In the event of a tie, DU uses the following tie-breaking hierarchy for 2026:
Students are advised to:
Before beginning the DU CSAS 2026 registration process, candidates should keep scanned copies of all the required documents ready. Depending on the category, quota, or program applied for, some additional certificates may also be required.
All uploaded documents are subject to verification, and candidates must produce the original documents during physical verification at the allotted college.
Mandatory Documents (For All Candidates)
Category & Reservation Certificates (If Applicable)
Candidates claiming reservation or supernumerary quota benefits must upload the relevant certificate issued by the competent authority.
Important: The candidate's name and parents' names on all reservation certificates must exactly match the details mentioned in the Class 10/Class 12 certificates and the CUET (UG) 2026 application form.
Program & Quota-specific Documents (If Applicable)
Depending on the programme or quota selected, candidates may also need to upload:
Documents Required During College Verification
After seat allotment, candidates must carry the original copies of the uploaded documents for verification at the allotted college.
The DU CSAS Portal 2026 is the official admission platform for undergraduate admissions to the University of Delhi through CUET UG 2026 scores. The admission process is conducted in three phases - Registration, Preference Filling, and Seat Allocation & Admission, with every stage having strict deadlines.
Candidates must complete registration, verify their academic details, fill program and college preferences strategically, and monitor simulated ranks before the final seat allocation rounds. Admissions are granted solely on CUET-based merit, subject mapping, eligibility criteria, and preference order.
This guide explains the complete DU CSAS process, important dates, registration fees, required documents, common mistakes to avoid, and key admission rules to help students navigate the DU admission process confidently and successfully.
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 undergraduate admissions. It works in three phases - Registration, Program & College Preference Filling, and Allocation-cum-Admission - based entirely on a candidate's CUET-UG score, program-specific eligibility, and preference order.
Visit ugadmission.uod.ac.in, click "New Registration," enter your CUET (UG) 2026 Application Number and Date of Birth, verify the auto-fetched details, upload the required documents, fill in the necessary academic information, and pay the non-refundable CSAS registration fee. Registration is complete only after successful fee payment.
There are three phases - Phase I (Registration), Phase II (Program & College Preference Filling), and Phase III (Allocation-cum-Admission). Candidates must complete each phase within the prescribed timeline to remain eligible for seat allocation.
Yes. CUET-UG 2026 is mandatory for admission to undergraduate programs at the University of Delhi. Candidates must have appeared in the required CUET subjects as per the program-specific eligibility criteria to participate in the CSAS admission process.
Candidates should keep their CUET (UG) 2026 Application Number, Class 10 and Class 12 marksheets, category or reservation certificate (if applicable), passport-size photograph, scanned signature, valid government-issued photo ID, and Sports/ECA or other program-specific certificates (where applicable) ready before registering.
The DU CSAS application fee is 250 for UR/OBC-NCL/EWS candidates and 100 for SC/ST/PwBD candidates. An additional 400 per program is applicable for BFA, B.A. (Hons.) Music, and B.Sc. (PE, HE & S) applicants, while 100 per quota is charged separately for ECA and Sports quota applications. All fees are non-refundable.
Yes. Candidates can edit permitted details only during the official correction window announced by the University of Delhi. However, certain information imported from the CUET application, such as personal details, cannot be edited through the CSAS portal. Programme and college preferences can also be re-ordered during the preference reordering window after simulated ranks are released.
During Phase II, candidates must map their CUET subjects with their Class XII subjects, verify their program-specific eligibility, and select all eligible program-college combinations. Arrange them carefully in the order of preference, save the choices regularly, and ensure the final preference list is submitted before the portal auto-locks it.
There is no fixed upper limit on the number of program-college combinations a candidate can select. Students are advised to fill as many eligible preferences as possible to maximise their chances of securing admission.
List your most preferred program-college combination first and continue in descending order of preference. Fill all eligible combinations instead of limiting your choices, and use the simulated ranks to strategically reorder your preferences before the final locking deadline.
Seat allocation is based on a candidate's CUET-UG score, program-specific eligibility, category, seat availability, and the order of program-college preferences submitted. The University allocates the highest possible preference for which the candidate is eligible, and multiple allocation rounds are conducted to fill vacant seats.
Simulated Ranks are indicative ranks released before the first allocation list to help candidates understand their admission prospects and reorder their preferences. Actual allocation is the final seat allotted by the University during an official CSAS allocation round, which candidates must accept within the prescribed deadline.
After seat allotment, candidates must log in to their CSAS dashboard, accept the allotted seat within the specified timeline, wait for document verification and approval by the allotted college, and pay the admission fee online to confirm their admission. Failure to complete any step within the deadline will result in cancellation of the allotted seat.
If a candidate is not allotted a seat in the first round, they are automatically considered for subsequent regular allocation rounds based on their saved preferences, merit, and seat availability. Candidates should regularly monitor their CSAS dashboard for updates and future allocation lists.
Yes. After accepting an allotted seat, eligible candidates may opt for Upgrade to be considered for a higher-preference program or college in the next allocation round. If a higher-preference seat is allotted, the previously accepted seat is automatically cancelled, and the candidate must complete the admission formalities for the upgraded allotment within the prescribed timeline.
After accepting an allotted seat, candidates can choose either Freeze or Upgrade. Selecting Freeze confirms the current allotment and removes the candidate from further upgradation rounds. Selecting Upgrade allows the candidate to be considered for a higher-preference program or college in the next allocation round, subject to merit and seat availability. Candidates must actively choose the desired option within the prescribed deadline.
Yes. Candidates can withdraw their admission through the CSAS portal by paying the prescribed withdrawal fee. Refunds, if applicable, are processed as per the University of Delhi's notified refund policy. However, the CSAS application fee and withdrawal fee are non-refundable.
No. Once the final preference-locking deadline has passed, program and college preferences cannot be changed. Candidates who have accepted a seat may opt for Upgrade, in which case only their already-saved higher preferences are considered in subsequent allocation rounds.
