AISSEE 2026 Stray Vacancy Portal: Fix Application Number Not Found

If you see an "Application Number Not Found" error on the AISSEE 2026 Stray Vacancy portal, it almost always means you are using your original AISSEE application number instead of the stray vacancy registration ID generated when you sign up for this round.

The AISSEE 2026 Stray Vacancy portal at exams.nta.nic.in/sainik-school-society requires a fresh registration separate from the main AISSEE 2026 process. Students on the merit list or waitlist who were not allotted a seat can apply for unfilled seats through this round. The steps below will help you resolve the error before the June 12, 2026 deadline.

• The stray vacancy portal is live at exams.nta.nic.in/sainik-school-society.
• You must register separately for the stray vacancy round — your AISSEE 2026 roll number alone will not serve as the login ID.
• Login requires your stray vacancy application number and the password you set during stray vacancy registration.
• The error is typically fixed by locating the correct application number in your stray vacancy confirmation email or SMS.
• Last date to apply is June 12, 2026 — resolve any login issues immediately.

What Is the AISSEE 2026 Stray Vacancy Round?

The stray vacancy round follows the main AISSEE 2026 admission process. When students who received seat allotments do not report by the school’s deadline, those seats become available again. NTA and Sainik School Society open a dedicated portal to fill these seats from the waitlist and other eligible students.

How to Fix the AISSEE 2026 Stray Vacancy Login Error

Work through these steps in order. Most students resolve the error within the first three steps.

1. Find your stray vacancy confirmation email or SMS. After registering on the stray vacancy portal, NTA sends a confirmation containing your stray vacancy application number. Use that number — not your AISSEE 2026 admit card number.
2. Visit the official portal directly. Open exams.nta.nic.in/sainik-school-society in your browser. Do not use saved bookmarks that may point to an outdated URL.
3. Select the correct class on the login page. Choose Class 6 or Class 9 to match exactly what you registered for. A class mismatch will trigger the error.
4. Enter the application number manually. Type each digit carefully. Avoid copy-pasting, as invisible trailing spaces or special characters in the clipboard can cause the error.
5. Clear your browser cache and cookies. Open browser settings, clear all cached data and cookies, close the browser completely, reopen it, and try logging in again.
6. Switch to a different browser or incognito mode. If Chrome is giving trouble, try Mozilla Firefox or Microsoft Edge. An incognito window bypasses stored session data that may be interfering.
7. Complete stray vacancy registration if you have not done so. If you never registered for this round, click the "New Registration" link on the portal and complete the process. This generates your stray vacancy application number.
8. Try during off-peak hours. Portal traffic peaks between 10 AM and 6 PM. Attempting to log in early morning or late evening reduces server-side load issues.

What to Do If the AISSEE 2026 Stray Vacancy Error Persists

If the troubleshooting steps above do not work, take these actions well before the June 12, 2026 deadline:

• Use the Forgot Password option. On the stray vacancy login page, click "Forgot Password." Enter your stray vacancy application number and date of birth. An OTP will be sent to your registered mobile or email. Use it to set a new password.
• Contact the NTA helpdesk. NTA publishes a helpdesk phone number and email ID on the official portal during active application windows. Visit exams.nta.nic.in/sainik-school-society for current contact details.
• Email with supporting details. Send your AISSEE 2026 roll number, full name, date of birth, and a screenshot of the error to the NTA helpdesk email. This speeds up account verification and resolution.
• Do not create a duplicate registration. Registering twice with the same AISSEE roll number will conflict and slow down resolution.
• Act well before June 12. NTA helpdesk volumes increase sharply near the deadline. Raising your issue at least two days in advance gives you time to resolve it.
