eSign an Authorization Letter Online with Aadhaar
Authorize someone to act on your behalf — collect documents, sign forms, or handle transactions. Legally valid under IT Act 2000. ₹15 per signature.
What is an Authorization Letter?
An authorization letter is a formal document in which one person (the 'authorizer' or principal) gives another person (the 'authorized person' or agent) permission to act on their behalf for a specific purpose. Common use cases include authorizing someone to collect documents from a government office, pick up a parcel, operate a bank account temporarily, handle property matters, or represent you in meetings you can't attend.
Authorization letters are distinct from Power of Attorney documents — they're typically used for single, specific, short-term tasks rather than ongoing legal representation. For example, asking a friend to collect your passport from Passport Seva Kendra, or letting a colleague receive an important courier, or giving your sister permission to access your bank locker once.
In India, authorization letters don't typically require stamp paper or notarization for most everyday uses. However, the receiving party (bank, government office, courier) may ask for identity proof of both parties. An Aadhaar eSigned authorization letter provides that identity proof automatically via the cryptographic signature.

Legal framework
Legally valid under Indian law
Authorization letters for specific, limited-scope tasks are eligible for Aadhaar eSign under Section 3A of the IT Act, 2000. Since they're not the same as a Power of Attorney for substantial legal matters, they don't typically need stamp paper or registration. The Aadhaar eSign provides both the signature and identity verification in one step, which is usually sufficient for the receiving authority to verify the authorization. For bank-related authorization (especially for transactions above ₹50,000), banks may ask for a physical signed letter with photo identification rather than accepting an eSigned version — always check with the specific bank first.
Primary reference: Section 3A, IT Act 2000
Important note
For high-value transactions or ongoing legal representation, use a Power of Attorney instead of an authorization letter. Banks and government offices may have specific authorization forms for their own processes.
