Aadhaar eSign OTP Failed? Common Authentication Issues & How Businesses Can Fix Them

Aadhaar eSign relies on OTP-based authentication to verify signer identity quickly and securely. However, many businesses face issues like OTP not received, authentication failure, or incomplete signing, which can disrupt onboarding and approval workflows.

This blog explains why Aadhaar eSign OTP failures occur and how businesses can fix these issues to ensure smooth and compliant document signing.

Why OTP Issues Happen in Aadhaar eSign

OTP failures usually occur due to factors outside the signing platform’s control, such as:

• Mobile number not linked with Aadhaar

• Network or telecom delays

• Incorrect Aadhaar details entered by the signer

• Repeated OTP attempts within a short time

Understanding these causes helps reduce friction during signing.

Common Aadhaar eSign Authentication Problems

1. OTP Not Received

This often happens when the mobile number is not updated in Aadhaar records or due to temporary network issues.

2. OTP Expired

Aadhaar OTPs are time-sensitive. Delays in entering the OTP can cause authentication failure.

3. Incorrect Aadhaar Details

Mismatch in Aadhaar number or personal details leads to failed authentication attempts.

4. Multiple Failed Attempts

Repeated incorrect OTP entries may temporarily block authentication for security reasons.

How Businesses Can Reduce Aadhaar eSign OTP Failures

To minimize OTP-related issues, businesses should:

• Inform users to update their Aadhaar-linked mobile number

• Provide clear signing instructions before authentication

• Enable retry mechanisms with proper guidance

• Use platforms that handle authentication failures gracefully

Good user communication is as important as technology.
