Hey. These are the documents that you might need to apply for the EWS certificate:

• Passport-sized photograph
• Aadhaar card
• ID Proof (Pan card, Voter ID, etc.)
• Land/property documents
• Affidavit/Self Declaration
• Residential proof/Domicile Certificate
• You might also need a valid proof of your income, i.e your income certificate

However, the documents required also vary from state to state.
