Sign a Document
Online with Aadhaar eSign
India's simplest way to legally sign documents from your phone — no printer, no courier, no office visit. Just your Aadhaar and an OTP.
What is Aadhaar eSign?
Aadhaar eSign is an electronic signature service authorized by the Government of India. It lets any Aadhaar holder sign documents digitally using a one-time password (OTP) sent to their Aadhaar-linked mobile number.
Every signature is legally equivalent to a wet ink signature — no physical presence required, no USB token, no DSC hardware.
EZNotary's Aadhaar eSign is powered through licensed Certifying Authorities (CAs) approved by MeitY, ensuring every signature meets the highest legal and security standards in India.
Recognized as a valid electronic signature under Section 5 of the Information Technology Act, 2000. Admissible as evidence in Indian courts.
