Yes, you could be denied a verification process because of an order difference of last name between your Aadhaar card and in your EWS certificate.

The acceptance standards for documents differ according to the government agency/institution. In some of them, they permit flexibility like accepting your name despite the surname being stated first, second, or any other order. In the case of others, they would insist upon and strictly accept only when the name is exactly the same throughout the documents.

Here is what you can do:

Contact the Issuing Authority:

Contact the Issuing Authority:

Contact the issuing authority where you received your EWS certificate, and ask if there is an option to correct the order of the names.

They can issue a re-issued certificate or may even give a clarification letter.

Meet with the Relevant Institution:

Contact the institution applying at and seek information regarding their process for verification of documents

Explain your situation and ask if there are any guidelines or requirements that the institution specifically follows about having mismatched names

Draft an Affidavit:

As much as possible, you can prepare an affidavit explaining the discrepancy, and stating that these are actually the same person's documents.

You will get the affidavit notarized for added credibility.

It is best to address the discrepancy early to avoid potential problems in your verification process.
