Your PAN card PDF — whether downloaded from the NSDL (now Protean eGov Technologies) portal or the UTI Infrastructure Technology and Services (UTITSL) portal — contains a legally valid digital signature. This signature certifies that the document was issued by the Income Tax Department of India through its authorised agencies and has not been altered. Verifying this signature online is now instant with VerifySign.in.
PAN card PDFs are issued and digitally signed by one of two agencies authorised by the Income Tax Department:
NSDL / Protean eGov Technologies: The older and more widely used agency. PAN PDFs issued here are signed with a certificate that identifies the signer as "NSDL e-Governance Infrastructure Limited" or "Protean eGov Technologies Limited". The certificate chain flows through NIC (National Informatics Centre) under India's CCA.
UTITSL (UTI Infrastructure Technology and Services Limited): The alternative PAN issuing authority. PDFs signed here display "UTI Infrastructure Technology and Services Limited" as the signer. The certificate structure is similar, rooted in India's CCA PKI.
If your PDF reader shows "Signature Not Valid" or "Signature Validity Unknown" on your PAN card PDF, it typically means one of two things: either the PDF reader doesn't trust the NIC/CCA certificate chain (most common — this is a trust store issue, not a document problem), or — rarely — the document has been altered. VerifySign.in can definitively tell you which case applies by performing a cryptographic verification against the actual certificate chain.
In the vast majority of cases, the PAN PDF is genuine and the issue is purely that India's government CAs are not in the default Adobe trust list.
Step 1: Download your PAN card PDF from the official NSDL/Protean portal (onlineservices.nsdl.com) or UTITSL portal if you don't have it already.
Step 2: Go to verifysign.in and click "Upload PDF". Select your PAN PDF. PAN card PDFs are usually not password-protected, so no password is needed.
Step 3: VerifySign.in analyses the embedded signature and displays the signer name (e.g., "Protean eGov Technologies Limited"), the signing date, certificate validity, and the overall verification status.
Step 4: If the signature is valid, you'll see a confirmed green verification status. You can then download the LTV-enabled PDF to get a permanent green tick in all PDF readers.
Bank KYC: Many banks and financial institutions now accept digitally signed e-PAN for KYC (Know Your Customer) verification. A verified signature provides additional assurance during the KYC process and can speed up account opening or loan approval.
Employer Verification: When joining a new employer, HR teams may request verified copies of identity documents. A PAN PDF with a confirmed valid signature is more reliable than a scanned physical copy and easier to share digitally.
Tax Filing & Financial Compliance: Verified e-PAN is accepted for tax filing, GST registration, and other compliance activities where proof of PAN identity is required.
Fraud Prevention: Verifying the digital signature confirms the PAN PDF hasn't been doctored — protecting against identity fraud in high-stakes financial transactions.
VerifySign.in processes your uploaded PDF using server-side cryptographic operations and does not store your documents beyond the session. Verification results are displayed only to you. Your PAN data remains private.
