what is esign in pan card

eE-Sign, in the context of a PAN card application, is a government-authorised and legally valid electronic signature service. It allows you to digitally sign your new or correction PAN application form online, eliminating the need for physical signatures and submitting paper documents. The most common and secure method is the Aadhaar OTP-based eSignature. By using this service, you authenticate your identity with an OTP sent to your Aadhaar-linked mobile number, which affixes a digital signature to your form, making the entire application process paperless and efficient.
