Students allotted a seat in DU CSAS 2026 must upload documents including their CUET UG 2026 scorecard, Class 10 and Class 12 marksheets, transfer certificate, and category certificate (if applicable) within the seat acceptance deadline — missing even one mandatory file can result in automatic seat cancellation.
Delhi University’s Common Seat Allocation System (CSAS UG 2026) allocates seats across multiple rounds at ugadmission.uod.ac.in. Once a seat is offered, students must log in, pay the acceptance fee, and upload all required documents before the window closes. The first allotment list is expected in mid-July 2026. Physical document verification at the allotted college follows later; the immediate requirement is the online upload.
- Seat acceptance is completed online at ugadmission.uod.ac.in — physical reporting to the college is notified separately for original document verification.
- All uploads must be legible, in PDF or JPG format, and within the file-size limits shown on the portal.
- OBC-NCL and EWS certificates must be valid for financial year 2025-26 — certificates from an earlier year are rejected.
- If your migration certificate or final marksheet has not been issued yet, download the undertaking format from admission.uod.ac.in and upload it in place of the original.
- Category and quota documents submitted at seat acceptance must match exactly what was uploaded during CSAS registration.
