## What the Aadhaar XML Verification API does

Aadhaar XML Verification takes a UIDAI offline eKYC file, validates the digital signature on it, and extracts the identity details, address and embedded photograph it contains.

This is the strongest Aadhaar check available without connecting to UIDAI directly. Because the signature is cryptographic, a tampered file fails verification outright, which no amount of image editing can get around.

## Where teams use the Aadhaar XML Verification API

1.  High-assurance Aadhaar verification without a document photo
    
2.  Extracting a verified photograph for face matching
    
3.  Capturing a cryptographically proven address
    
4.  Onboarding where document forgery is a real concern
    

## Frequently Asked Questions (FAQs)

Where does the customer get the XML file?

They download it from the UIDAI portal, choosing a share code that protects the file. They provide both to you.

What does signature validation prove?

That the file was issued by UIDAI and has not been altered since. It is far stronger evidence than a photograph of a card.

Can I use the photograph for face match?

Yes, and it is a good source since it comes from a signed file rather than a resubmitted image.
