A community certificate number is a unique identifier associated with a community certificate issued by the government to individuals belonging to certain reserved categories like Scheduled Castes (SC), Scheduled Tribes (ST), and Other Backward Classes (OBC). This certificate helps avail various governmental benefits and schemes intended for these categories. The number is crucial as it helps verify and authenticate the individual's claim to belong to a specific community. It is usually required during educational admissions, job applications, and other official procedures where reservation benefits are applicable.
