I have an old caste certificate with me. Do I need to apply for it again ?
Caste certificate has lifetime validity. So you don't need to apply for it again. The caste certificates once issued would remain valid till the government revoke them. However, group classification certificates for the OBCs for employment purposes would be given annually, if the recruiting authority insists.
