CSAB Choice Filling 2026: Date, Link, How to Add/Delete/Rearrange Choices

The candidates must fill in fresh choices during the CSAB choice-filling process. The previously filled Choices during JoSAA 2026 rounds (if any) stand NULL AND VOID and hence will NOT be considered for allotment in CSAB counselling rounds. 

Registered candidates can access the CSAB 2026 choice filling link for all three CSAB counselling processes below:

NEUT	will be available here
Special Round	will be available here
Supernumerary	will be available here

Students can find a step-by-step breakdown of the choice filling for CSAB 2026. For those who are participating in the CSAB Special Rounds, the choice-filling process is as follows: 

• Step 1 is to fill the preferences: All registered candidates have to fill in choices of courses and colleges in the CSAB choice filling process in order of preference. JoSAA choice list will not be applicable here. Fill fresh choices.
• Step 2 is to save all the choices filled: Keep saving th choices after adding a few choices, to ensure that the data is saved. Do not worry, choices can be changed after saving.
• Step 3 is to lock the choices: Lock the choices only after you are sure of the choice preference list. After locking the choices, candidates cannot edit the choice list. Locking means final submission of the list. If a candidate does not lock the choices before the deadline, their choices will be auto locked, and the auto locked list will be used for seat allotment.

How to edit the CSAB Choice Filling after Locking the Preference?

The authority does not provide the choice editing option once the choice filling dates are over and the choices have been locked. Those who are willing to edit their locked choices may do so by submitting an online request in the CSAB portal well before the choice filling deadline. An OTP will be sent to the registered mobile number and email, and candidates will have to enter the same to validate their request. Once validated, the candidate’s choices will be unlocked.

Points to Remember

Candidates who have secured seats in JoSAA 2026 rounds after paying PAF are also eligible to participate in CSAB special rounds. Such candidates, while retaining currently allotted seats, are also required to fill their choices of seats afresh. Students will not be allowed to edit their choice-list after the deadline for choice filling, i.e., candidates cannot change the order of their choices OR add any more choices OR delete any choices from their choice-list after the deadline for choice filling. Candidates are strongly discouraged from sharing their login information/credentials with others. Candidates must fill and save at least one choice of seat to be considered for seat allotment. Candidates who failed to fill and save at least one choice will not be considered for seat allotment. Candidates must download and take a printout of their locked choices.

Registered candidates can submit their choices of institute and programme in order of their preference. List of available choices for institute and programs is displayed as per the eligibility of candidate. Students can fill in as many choices as they wish from the list of available choices. During CSAB 2026 choice filling, candidates can perform following actions against choices they are filling:

Add Choice

• The choices submitted and residing in the right pane will be considered for allotment after pressing the ‘SAVE’ button.

Delete Submitted Choices

• Candidates can delete any submitted choice by pressing the “Delete” button on the right pane.

Locking of Choices

• Choices once locked cannot be unlocked or modified
• After locking, system will redirect to candidate’s Home page.
• If candidates fail to lock their choices by the last date & time, their last saved choices will be automatically locked by the system.

The process for filling supernumerary choices in CSAB includes the following steps:  

• All candidates who have successfully registered need to enter new choices for academic programs. Choices submitted during JoSAA/CSAB Special rounds are not considered valid.  
• It is essential to save the new choices made, as they are not saved automatically. At least one choice must be saved to be eligible for seat allocation.  
• After finalising the choice list, candidates are required to lock their choices; if they do not, it will automatically be locked after the schedule for choice locking, and that will be used for seat allocation.

Before proceeding with the NEUT choice filling, candidates should verify the institutes that are taking part in the CSAB NEUT counselling. NIT Rourkela holds the CSAB NEUT 2026 specifically for the seats available in Indian Institutes that are not included in CSAB 2026 or JoSAA 2026, along with certain seats at NERIST, Itanagar. The process for CSAB NEUT choice-filling includes the following steps:  

• Selecting Choices: Choose the colleges and courses, then organise them based on preference.  
• Saving and Locking Choices: Save the selected choices to prevent loss in case of any mistakes.  
• Downloading Locked Choices: Lock the choices when satisfied and before the cutoff date. Once submitted, candidates can also print the choices for their records.

Once candidates have filled in their choices, the allotment of seats takes place. The allocation of seats will be determined solely based on the candidates' JEE Main ranks and their categories, while considering the number of seats available. Candidates can view the seat allotment results by logging into the official CSAB website - csab.nic.in. After the seat allotment is finalised, candidates must complete the online reporting process, which includes submitting their willingness, verifying documents, and paying the seat acceptance fee.
