Hello,

A Category Certificate ID number is the unique number printed on your caste or category certificate.
It helps the authorities verify your certificate online.

You can find it on your SC/ST/OBC/EWS certificate , usually near:

• the certificate number

• the issuing authority details

• the top or bottom of the certificate page

If your certificate does not show any ID number, then the certificate number itself is used as the Category Certificate ID.

Hope it helps !
