How to Apply for Aadhaar Card Online — Step-by-Step Guide

What is Aadhaar Card?

Aadhaar is a 12-digit unique identity number issued by UIDAI (Unique Identification Authority of India) to every resident of India. It serves as proof of identity and address anywhere in India. The Aadhaar system is the world's largest biometric ID program, covering over 130 crore residents.

Aadhaar is used for:

• Bank account opening and KYC verification
• Mobile SIM purchase
• Income tax filing and PAN linking
• Government scheme benefits (LPG subsidy, PM Kisan, scholarships)
• Passport application and other government services
• Digital signature and e-verification

Who is Eligible?

• Any resident of India (including children and infants)
• No age restriction — even newborns can get Aadhaar (Baal Aadhaar)
• No citizenship requirement — residency is sufficient
• NRIs with Indian passport can also apply
• Foreign nationals who have resided in India for 182+ days in the preceding 12 months

Baal Aadhaar (Blue Aadhaar): For children under 5 years. It is issued without biometrics (no fingerprint or iris scan). When the child turns 5, biometrics must be updated (free of cost). Biometrics are updated again at age 15.

Documents Required

You need one document from each category:

Proof of Identity (any one)

• Passport
• PAN card
• Voter ID
• Driving License
• Government Photo ID
• NREGA Job Card
• Arms License
• Photo ID issued by a recognized educational institution

Proof of Address (any one)

• Passport
• Bank Statement (last 3 months)
• Voter ID
• Utility Bill (electricity, water, gas — not older than 3 months)
• Ration Card
• Property tax receipt
• Rental agreement (registered)
• Post office passbook with address

Proof of Date of Birth (any one)

• Birth Certificate
• Passport
• Class 10 Marksheet
• PAN Card
• Government hospital birth certificate
• Driving License with DOB

For children under 5: Only birth certificate is needed. Aadhaar of one parent is mandatory. The child's Aadhaar is linked to the parent's Aadhaar.

No documents at all? If you have no documents, you can use an "Introducer" — a person who already has Aadhaar and is registered with UIDAI as an introducer at the enrollment center. Head of Family (HoF) based enrollment is also available.

Step-by-Step Process (Online Appointment + Offline Enrollment)

Aadhaar enrollment requires a physical visit to an enrollment center for biometric capture. However, you can book an appointment online to avoid long queues.

Step 1: Visit the UIDAI Appointment Portal

Go to appointments.uidai.gov.in

Step 2: Select "Book an Appointment"

Choose your city and preferred Aadhaar enrollment center. You can also search by PIN code.

Step 3: Fill in Your Details

Enter your name, mobile number, email, and preferred date/time.

Step 4: Choose Appointment Slot

Select an available slot. You'll receive a confirmation SMS and email with appointment details.

Step 5: Visit the Enrollment Center

On the appointment date, carry:

• Appointment confirmation (printed or on phone)
• Original documents + photocopies
• Mobile phone (for OTP verification)

Step 6: Fill the Enrollment Form

At the center, fill the enrollment form with your personal details. The operator will assist you. Verify all details carefully — especially your name spelling, date of birth, and address.

Step 7: Biometric Enrollment

At the center:

1. Submit your documents for verification
2. Photograph will be taken
3. Fingerprints of all 10 fingers scanned
4. Iris scan of both eyes

Tip: Ensure your fingers are clean and dry. Wet, oily, or injured fingers can cause scan failures. If fingerprints fail, iris scan is used as the primary biometric.

Step 8: Review and Confirm

Before final submission, review all your details on the operator's screen. Check name, DOB, gender, address, and mobile number carefully. Any error now will require a paid update later.

Step 9: Collect Acknowledgment Slip

You'll receive an Enrollment ID (EID) — a 14-digit number along with date and time. Keep this safe — you'll need it to check status and download e-Aadhaar.

Step 10: Track Your Aadhaar Status

Visit uidai.gov.in → "Check Aadhaar Status" → Enter your EID number.

Offline Process (Walk-in at Enrollment Center)

If you prefer not to book online, you can directly visit any Aadhaar enrollment center:

1. Find a center: Use the UIDAI locator at bhuvan-app3.nrsc.gov.in/aadhaar or search on Google Maps for "Aadhaar enrollment center near me"
2. Walk in during working hours (usually 9:30 AM to 5:30 PM, Monday to Saturday)
3. Carry documents — originals and photocopies of POI, POA, and DOB proof
4. Wait for your turn — walk-in applicants are served after appointment holders
5. Follow steps 6-9 from the online process above

CSC Centers: Common Service Centers (CSC) across India also offer Aadhaar enrollment services. Find one at locator.csccloud.in.

Fees

Important: New Aadhaar enrollment is always free. If any center charges you for new enrollment, report it to UIDAI helpline 1947.

Common Problems and Solutions

Important Tips

1. Keep your mobile number updated — it's linked to your Aadhaar for OTP verification across all services
2. Download e-Aadhaar as a backup from the UIDAI website — it is legally valid and accepted everywhere
3. Don't share your Aadhaar number publicly — use masked Aadhaar (shows only last 4 digits) when possible
4. Update address whenever you move — you can do it online at myaadhaar.uidai.gov.in
5. Lock your Aadhaar biometrics when not in use — go to myaadhaar.uidai.gov.in → Lock/Unlock Biometrics
6. Use mAadhaar app — Download from Play Store/App Store for quick access to your Aadhaar on mobile
7. Use Virtual ID (VID) instead of Aadhaar number for KYC verification to protect your privacy
8. Visit early morning — Enrollment centers get crowded after 11 AM
9. Check for free update camps — UIDAI periodically runs free update camps, especially for biometric updates
