Dear,

The Central Government of India classifies some of its citizens based on their social and economic condition as Other Backward Class (OBC), and are statutorily termed Socially and Educationally Backward C lasses (SEBC). The central and state governments have identified SEBCs and offer them reservation.

If your name is in respective list then you can obtain your respective certificate.

If you have sebc certificate in regional language of state but your name is not found in obc list of  central  gov. Then you can only enjoy the benefit of reservation in state or state level exam or education.  At central level you are in unreserved category.
