Aadhaar eSign

A legally valid electronic signature method in Zoho Sign that verifies an Indian signatory's identity using their Aadhaar number and OTP authentication, recognised under the IT Act.

What Is Aadhaar eSign in Zoho Sign?

Aadhaar eSign in Zoho Sign is an electronic signature mechanism for Indian residents that uses the Aadhaar biometric identity database for authentication. The signatory enters their Aadhaar number and verifies their identity via an OTP sent to their Aadhaar-linked mobile number, creating a legally valid signature under the IT Act and Electronic Signature and Electronic Authentication Technique and Procedure Rules.

Legal Recognition

Aadhaar eSign is recognised by the Controller of Certifying Authorities (CCA) of India and is legally equivalent to a physical signature for most document types covered by the IT Act. It carries stronger identity assurance than a standard email-based e-signature because the signatory’s identity is verified against a government database.

Use Cases in India

Aadhaar eSign is used for agreements requiring stronger identity assurance: loan agreements, property transactions, employment contracts, and government-facing documents. It is particularly valuable when the counterparty is an individual (not a company) whose identity cannot otherwise be verified independently.
