Sir, I am from Tripura. I made my state OBC in 4/2024 and central OBC in 6/2024 and with the central OBC I made my OBC ncl in 4/2025 as per the format given by jee adv this year but I can't see anything like catagory certificate number or ID in my NCL. Yes there's a catagory no in central OBC certificate starting with OBCS/XXXX/XXXXX and my central OBC no OBCC/XXXX/XXXXX but there nothing like that in my NCL there something a 4 digit number only written in my NCL under which the date of issuing is written. Now NTA wants OBC ncl number with also after 1/4/2025 what number should I fill? Can you help me by collecting the proper and exact information regarding it , I would be very grateful to you.

Ans: Hi,
Yes, an OBC NCL certificate has a unique ID number, often referred to as the certificate number or serial number.

Where to Find the Number
The format and exact location of this number can vary by state and issuing authority, but it is usually printed prominently on the

Common Locations:
You can typically find the number in the bottom left corner or the top left/right corner of the certificate.

Format:
The number is usually an alphanumeric string that ranges from 8 to 12 characters long, sometimes including letters and other symbols, such as ABC/XYZ/OBC/M-7298/20XX.

Alternative Name:
It may also be referred to as the "Acknowledgement Number" or "Rev. Case Number."

Central vs. State List Entry Number
When completing application forms for admissions or jobs (such as JEE, NEET, etc.), you might be required to provide two different numbers:
1. The certificate number (the unique ID on your specific document).
2. The Entry Number or Serial Number of your caste in the Central List of OBCs.

If you still have doubts, feel free to approach the appropriate officer nearby for assistance.
