If the NEET correction window does not permit you to correct the signature and fingerprint images, you can immediately contact the NTA NEET helpdesk via email, mentioning your application number and clearly explaining the issue.

In many cases, such upload errors can only be resolved through a designated “discrepancy” email or portal. Although certain document fields may remain locked during correction, candidates might be asked to rectify specific image-related mistakes.

Also, you can try to use the correction window to see if you can change your signature there. The correction window will be valid from March 10-12, upto 2 PM. To know more about the NEET 2026 correction window, visit the link below:
