Two signature types, two very different use cases. This short explainer covers when to reach for Aadhaar eSign and when a DSC is the right call — and how IOUX runs both on one workflow.
Key takeaways
- Both Aadhaar eSign and DSC are legally valid electronic signatures under the IT Act, 2000.
- Aadhaar eSign is OTP-based, instant, and ideal for individuals signing remotely at scale.
- A DSC is a hardware/token-based certificate suited to authorised signatories and filings that mandate it.
- Per-signer cost, signer convenience and any statutory requirement decide the choice.
- IOUX supports multiple signature methods on one execution workflow with a court-admissible record.

Aadhaar eSign lets an individual sign a document using an OTP sent to the mobile number linked to their Aadhaar, through a licensed eSign provider. It is fast, needs no hardware, and suits high-volume remote signing.
A Digital Signature Certificate is issued on a secure token by a licensed Certifying Authority and is typically used by authorised signatories, and in filings that specifically require it.
Conclusion
For most remote, high-volume individual signing, Aadhaar eSign wins on speed and convenience; reach for a DSC where a filing or signatory role requires it. The right answer is often “both, on one workflow” — which is exactly what IOUX is built for.
Action items
- List who signs your documents and how they prefer to sign.
- Check whether any filing you do mandates a DSC.
- Estimate monthly signing volume to compare per-signer cost.
- Book an IOUX demo to map both methods onto one workflow.
FAQs
Is Aadhaar eSign legally valid in India?
Yes. Aadhaar eSign is an electronic signature recognised under the Information Technology Act, 2000, when carried out through a licensed eSign service and a valid Aadhaar-based authentication.
When is a DSC required instead of eSign?
Certain filings and authorised-signatory scenarios specifically require a Digital Signature Certificate (for example some MCA/GST/tender contexts). Where a statute or portal mandates a DSC, use a DSC.
Can one workflow use both?
Yes. On IOUX a single execution flow can route different parties to the signature method that suits them, while preserving one consolidated, court-admissible audit trail.
