What is DU CSAS Phase 1 Seat Allotment 2026?
The Common Seat Allocation System (CSAS) Phase 1 is the first round of seat allocation conducted by Delhi University for undergraduate admissions based on CUET UG 2026 scores. DU allots seats across affiliated colleges based on CUET UG merit, program-college preferences filled in the CSAS portal and category-wise seat availability.
After the Phase 1 allotment result is published, students have a defined window to review their allotted college and program, accept the seat online and report to the college for document verification. Students who do not accept the seat within the deadline forfeit their allotment and may miss their chance in future rounds as well.

How to Accept DU CSAS Phase 1 Allotted Seat 2026
Accepting your Phase 1 allotment is a two-step process: online acceptance on the CSAS portal followed by payment of the admission fee. Both steps must be completed within the acceptance window to secure your seat.

- Navigate to the Phase 1 Seat Allotment section on your dashboard.

Freeze, Float and Slide Options Explained
When accepting your Phase 1 allotment, you must choose one of three upgrade options. This choice determines your eligibility for upgrades in subsequent allotment rounds.
| Option | What It Means | Best For |
|---|---|---|
| Freeze | You are satisfied with the current allotment. No upgrades will be considered in future rounds. | Students who received their top preference |
| Float | Accept the current allotment but want an upgrade to a higher-preference program in the same college in later rounds. | Students happy with the college but who want a better program |
| Slide | Accept the current allotment but want an upgrade to any higher-preference program or college in later rounds. | Students who want the best possible upgrade across all preferences |
If you choose Float or Slide and receive an upgrade in a later round, the Phase 1 allotment is automatically cancelled and replaced by the new allotment. You must then accept and report to the new college within that round’s deadline.
