How to Validate Signature on Aadhaar Card — Easy Steps

If you want to validate signature on Aadhaar card then you’ll discover a quick way to check it is genuine and accepted.

Why you should check the signature

Your downloaded e-Aadhaar has a digital signature from the UIDAI. Checking it means you know the file is original and not tampered with. It helps when you submit it to banks or government departments.

Quick Checklist — What to do first

• Download your e-Aadhaar PDF from the official UIDAI site.
• Open it using Adobe Reader (desktop) or a PDF reader app on mobile.
• Scroll to the signature panel at last page.
• Click “Validate Signature” (desktop) or tap certificate details (mobile).
• Look for “(n)Code Solutions CA 2014” as certificate issuer to confirm.

Desktop vs Mobile — here’s a quick guide

Desktop (Windows/Mac):
Open PDF → look for yellow question mark or “Validity Unknown” icon → right-click → Validate Signature → check certificate.  
Mobile (Android/iOS):
Open e-Aadhaar PDF in reader app that supports signature validation → tap signature icon → view certificate → trust if issuer is correct.  

Real-Life Example

Ravi downloads his e-Aadhaar to open it on his laptop. He sees a yellow question mark next to the signature. He right-clicks, chooses “Validate Signature”, finds the issuer line as “(n)Code Solutions CA 2014”, clicks OK and then the green tick appears. He then sends it to his bank for KYC—no issues. Simple, right? 

If validation fails — quick tip

If the certificate shows invalid:
• Download latest e-Aadhaar again.
• Update your PDF reader to the latest version.
• On desktop add the UIDAI certificate to trusted certificates manually.
