If your Aadhaar photo doesn’t match your live capture photo on your JEE Main 2026 form, fix it during the correction window. The National Testing Agency lets you update things like personal details and photos at that time. If you leave the mismatch, you’ll probably run into trouble during verification at the exam center. So, make things easier for yourself—get your correct photo and Aadhaar details ready, and upload them as soon as the correction window opens. If the window’s not open yet, just sit tight and watch for the official announcement. Don’t fill out another form, or you’ll risk creating duplicate applications.
