Hello Student,

Sorry to say you but actually you have not mention that where you have filled your wrong aaahar number. That's why it is quite impossible to tell about all examinations. However you can check it from your own just by asking on their official helpline number or mail address. However if you are talking about Neet 2022 correction DNS per my knowledge there is no such options to change your Aadhar card number in in NEET 2022 form. Actually this is your one and only identity proof that's why maybe there is no options to change that however you can contact to direct authority by calling them or reaching out through email.
