Aadhar has completely redefined how electronic signatures work in India. Aadhaar authentication is widely used in G2C service, filing income tax returns, applying for PAN, or even availing healthcare services. Aadhar verification has been made mandatory for most government services and opening bank accounts, mobile connections, etc.

Aadhar based digital signature is growing exponentially in the corporate sector. Aadhar eSign has a lot of benefits compared to traditional digital signature certificate (DSC).

Almost every individual in India has Aadhar, which makes Aadhar e-sign one of the most viable alternatives to a conventional handwritten signature. However, corporates need a system to request digital signatures and validate Aadhar securely.

A handful of eSignature software is available in the market that facilitates secure Aadhar based digital signing process. However, it’s hard to find tools that meet all the requirements for validating & e-signing documents using Aadhaar.

This article will introduce you to some of the best tools that validate & eSign Aadhaar securely.

What is Aadhaar eSign?

Aadhar eSign is the latest method of signing a document or verifying the identity electronically using a 12-digit Aadhar number issued by UIDAI. Aadhaar based digital signature or eSign using Aadhar replaces the need of DSC and allows every Indian citizen to sign any document using their Aadhar number digitally. 

Aadhaar based digital signature saves time and cost incurred to verify documents. Still, the most significant advantage of Aadhar signing is that any Indian citizen can sign documents electronically without any Digital Signature Certificate or a specialized hardware.

How to Validate Electronic Signature in Aadhaar?

 Aadhaar eSign service providers allow signing a document, requesting a signature, and validating a signature online through a series of algorithms.

Step 1: Requesting a Signature

The authenticator builds a form with specified details like the signee’s name, DOB, gender, etc. If the document must be signed separately by multiple signees, the requestor can even define fields to be filled by the signee themselves. These documents are sent through a secured link to the signatory usingthe digital signature software.

Step 2: eSign Using Aadhaar

Aadhar based eSign can be of two types – Through Biometric and OTP. While biometric verification is widely used to open bank accounts and avail telecom services, OTP verification is used for KYC and other in-house document signings.

As the signer receives the document to be signed, he can verify the document and details. Once he confirms that the document is valid and ready to be signed, he clicks “eSign Using Aadhar” (widely used for OTP verification).

The signee is redirected to a Secured page to enter a 12-digit Aadhar number or 16 Digit Virtual ID (VID). Then, the signee receives an OTP on their registered mobile number, which he must enter to eSign the documents.

The server verifies fields with pre-verified data of the signee and confirms the signature.

Step 3: Validating the Signature

The requestor or authority receives a prompt that the signer has signed the document. He can open the document and view specified details of the signee and timestamp.

Why Choose Aadhar eSign over DSC?

The Digital Signature certificate concept failed to make a space in India because the process was too complicated and expensive. Digital Signature was limited to MCA filing, IT return verification, e-tendering, and ROC filing.

Aadhar made digital verification easy and cost-effective. Here are a few reasons why every company should choose Aadhar based digital signature over DSC.

  • Feasible

    Previously, users needed a Digital Signature Certificate (DSC) issued by CA (Certifying Authority) in USB token form. A person had to submit all the details and get approved by CA for getting a DSC. Aadhar replaced the whole process by allowing people to sign documents using a 12-digit Aadhar number and a registered phone number.

  • Cost-Effective

    A DSC token costs around Rs 1000-2000 depending upon the class and validity time of the DSC. A DSC is generally valid for 1-2 years and must be renewed from time to time. Aadhar is free and valid for a lifetime, making it a cost-effective option.

  • Accessibility

    Signees need to have DSC tokens present with them physically for signing documents digitally. Aadhaar based eSign needs only the 12-digit Aadhaar number and the registered mobile number to sign documents.

  • No Prerequisites

    DSC-based digital signing needs software like JAVA installed on the PC, while Aadhaar based signature doesn’t require specialized software.

  • Remote Signing

    Users can eSign with Aadhaar for any device, including iOS and Android Devices, while DSC can only be used from a PC.

  • Availability

    Only a few Indian business owners have DSC, while Aadhar is available to almost every Indian. This makes eSigning possible for every Indian.


Aadhar is probably the most common ID even Indian hold. Using Aadhar to eSign documents, consent forms, and contracts is a significant step towards digital India. Aadhaar based signature is the future of eSignatures in India.

Several digital signature software solutions are available to facilitate Aadhaar based eSigning process, which can be integrated with any document management system.

eSign using Aadhar helps small and medium business owners and entrepreneurs digitalize their business workflow and cut manual processing costs.

Therefore, choosing the right digital signature software will help your organization close deals quickly, reduce cost, increase productivity, and more.
