How eSign Services Works?


Let's understand how the eSign Service works.

In India, electronic signatures are regulated by the Controller of Certifying Authorities (CCA). The CCA approves organizations called Certifying Authority (CA) that issue digital certificates.

Different technology providers are involved in the process:

- Application Service Providers (ASPs) – These are platforms where users upload documents and start the signing process.

- eSign Service Providers (ESPs) – These providers verify identity and generate digital signatures.

Through this system, users can safely eSign PDF documents, sign electronic documents, and complete digital paperwork using an eSign APP or web platform.

Why eSign Is Not Working: Common Reasons


There are several reasons why an electronic signature not working error may appear.

1. Incorrect Aadhaar Details


One common reason for Aadhaar eSign not working is incorrect Aadhaar information during verification.

If the Aadhaar number or mobile number does not match the official records, the system cannot verify the eSign User.

How to fix it

- Make sure the mobile number is linked to Aadhaar
- Enter details exactly as registered

This usually works as a quick Aadhaar eSign error solution.

2. OTP Not Received During eSign


Many users face the OTP not received eSign issue while trying to sign a document online.

This may happen because of:

- SMS delays
- Aadhaar mobile number is not active
- DND settings are blocking messages

How to fix it

- Wait a few minutes and request OTP again
- Check your network signal
- Make sure the Aadhaar-linked mobile number is active

These steps often help fix eSign error online.
