What Can Be Edited in CAT 2026? Editable Fields, Locked Details and How to Correct Them

What Can Be Edited in CAT 2026?

Registered candidates are expected to be able to edit only three things in their CAT 2026 application form: photograph, signature and test city preferences. Every other detail, including name, date of birth, email ID, mobile number, category and academic details, is expected to stay locked.

CAT 2026 registration closed on September 22, 2026, and the exam will be held on November 29, 2026. The correction window is the last chance to fix upload and city problems before the admit card is released on November 4, 2026.

IMPORTANT: IIM Indore has not yet confirmed the CAT 2026 correction window on iimcat.ac.in. Current reports point to an opening around October 5, 2026, with a very short window (possibly closing around October 6). Treat all correction window dates as tentative and reconfirm them on iimcat.ac.in.

Key Takeaways

• Editable fields are expected to be limited to photograph, signature and test city preferences.

• Name, date of birth, email ID, mobile number, category and academic details are expected to be locked.

• Only candidates who registered and paid the application fee by September 22, 2026 can use the window.

• There is expected to be no fee for using the correction window.

• The window is a one-time, short facility, so prepare your corrected files in advance.

• Changing a test city preference does not guarantee that city will be allotted.

CAT 2026 Editable Fields at a Glance

Editable Fields in Detail

1. Photograph

You can replace your uploaded photograph with a new one, for example if the original was blurred, wrongly cropped, too large or in the wrong format. The new image must meet the prescribed format, size and dimension rules. See our CAT 2026 Photo Correction Guide for the full checklist.

2. Signature

You can re-upload your scanned signature if the first upload was unclear, cropped or did not meet the file requirements. Your signature should be your regular signature on plain white paper. See our CAT 2026 Signature Correction Guide for the full checklist.

3. Test City Preferences

You can change or reorder the test cities you selected during registration. The CAT application allows candidates to choose multiple city preferences in order of priority. IIM Indore allots the final city and centre depending on seat availability, so a changed preference is a request, not a guarantee.

Fields That Cannot Be Edited (Expected)

The editable fields for CAT 2026 are extrapolated from the consistent pattern of earlier cycles. IIM Indore could change the list in its official notification.

CAT 2026 FAQs

What can be edited in the CAT 2026 application form?

Candidates are expected to be able to edit only three things during the CAT 2026 correction window: their photograph, their signature and their test city preferences. This is based on the pattern followed in previous CAT cycles and current reporting, and should be reconfirmed on iimcat.ac.in.

What cannot be edited in the CAT 2026 application form?

Name, date of birth, registered email ID, mobile number, category and academic qualification details are expected to be locked and cannot be changed through the correction window.

Can I change my date of birth or category in CAT 2026?

No. Date of birth and category are identity and eligibility details and are not expected to be editable. If you spot a serious error, contact the official CAT helpdesk with supporting documents, but a change is not guaranteed.

Can I change my CAT 2026 test city?

Yes, test city preferences are expected to be editable during the correction window. However, changing a preference does not guarantee allotment, because IIM Indore allots the final city and centre based on seat availability.

Is there a fee to edit the CAT 2026 application form?

No. The CAT correction window has been free in previous cycles and is expected to be free for CAT 2026 as well. The window does not reopen fee payment.

Can I edit my CAT 2026 form after the correction window closes?

No. The correction window is a one-time facility. Once it closes, you are not expected to be able to make further changes, so submit all your edits before the deadline.
