Hello,

.

Your Caste certificate's validity depends on its purpose. For example if you belong to OBC-NCL, your Category certificate will be valid for 3 years.You need to get your income reviewed every 3 years based on your annual income for the past 3 years. Lets say your OBC certificate is only for Category and reservation purposes, the validity is life long. Now if you belong to General Category but can avail EWS reservation, the EWS certificate will be valid only for 1 year but General Category certificate is valid for life long.
