Hello aspirant,

For claiming SC reservation you will have to make your caste certificate from your tehsil or sdm office. For claiming reservation in AIQ you will have to produce Central castes certificate which also you will get from SDM office. There is just minor differences of format in both of them. You can also apply online on your state backward classes welfare portal. You can visit www.india.gov.in and apply for issuing caste certificate. Otherwise you can get it also offline by

1.Visiting Tehsil or SDM office and ask for caste validity certificate application form.

2. Fill in the form correctly and submit it to the officer.

They will verify all your documents and if you fall under sc caste list they will prepare a caste certificate for you and will give you.

For claiming reservation mainly you have to produce your caste certificate or central caste certificate

Hope I may have resolved your query

Hope it helps!
