Aadhaar Enrolment UIDAI 2026 – Book Aadhaar Appointment Online

Aadhaar Enrolment (Complete Guide)

Aadhaar enrolment is a free and voluntary process for generating a 12-digit Aadhaar number from UIDAI. During enrolment, your demographic information (name, address, date of birth and gender) and biometric details (fingerprints, iris scans and a photograph) are securely recorded to create a verified identity. Once the Aadhaar number is assigned, you can download an e-Aadhaar or receive a physical Aadhaar card for identity verification across various services.

Aadhaar is not a proof of citizenship; it only establishes identity for residents of India.

Eligibility for Aadhaar Enrolment

Aadhaar enrolment is available to:

✔ Residents of India

Any individual who has lived in India for at least 182 days in the last 12 months, including:

• Indian citizens
• NRIs staying in India
• Foreign nationals with valid Indian residence documents under special conditions

✔ All Age Groups

Aadhaar can be issued to:

• Newborns and children
• Adults and senior citizens
  For children below 5 years, a Baal Aadhaar (blue card) is issued. No biometrics are taken until they turn 5 years old. Updating biometrics becomes mandatory after age 5 and again after age 15.

✔ No Citizenship Requirement

Aadhaar proves identity for residents; it is not a proof of Indian nationality.

Important: Enrolment Without Standard Documents

If you do not possess standard documents, you may still enrol using the Head of Family (HoF) method or the Introducer System, where a verified individual confirms your identity.

HoF Based Enrolment Introducer System

Documents Required for Aadhaar Enrolment

UIDAI accepts a wide range of documents. Ensure documents are:

• Valid

• Birth certificate (for children)
• Marriage certificate

A valid passport and OCI/PIO documents may be required depending on eligibility.

Incomplete Documents

If you cannot produce standard proofs, the Introducer or HoF-based methods may be used with supporting forms such as the Aadhaar enrolment/update certificate format.

Always visit UIDAI-authorized Aadhaar Seva Kendras (ASKs) or Permanent Enrolment Centres (PECs) to avoid fraud.
