Hello,
If your hall ticket number is showing as invalid, first ensure you entered it correctly, including any leading zeros or special characters. Double-check the format against your official hall ticket document. If the problem persists, contact the examination authority or the helpline provided for technical support. They can verify your details and resolve any issues. Additionally, check for any announcements or updates regarding technical issues on the official exam website.
Hope this helps you,
Thank you
