Dear Student, 

If you mistakenly uploaded a wrong document (like a voter ID with the incorrect birth date) during the JEE Main application correction window and now need to upload the correct document showing your accurate date of birth, you should immediately log in to your JEE Main candidate portal using your application number and password during the open correction period. Go to the ‘Application Form Correction’ section where you initially uploaded the documents. There, you can delete or replace the previously uploaded document with the correct one by following the on-screen instructions to re-upload the accurate birth date proof. Ensure the new document meets the prescribed file format and size requirements before submitting the correction. If the correction window is closed, contact the NTA helpline immediately to inquire about possible remedies, but typically, changes are only allowed while the correction window is active. Always confirm document changes well before the deadline to avoid rejection of your application due to incorrect details.
