⚠️ Common Mistakes to Avoid

  • Failing to complete Mandatory Biometric Updates for children at age 5 and 15 (causes Aadhaar deactivation and biometric authentication failures)
  • Using unverified local plastic PVC card print shops (UIDAI advises ordering the official secure PVC card from myaadhaar for ₹50 to guarantee valid security features)
  • Not locking biometrics on the mAadhaar app (leaves biometric auth vulnerable to unauthorized spoofing)

Frequently Asked Questions

What is the official password to open a downloaded e-Aadhaar PDF?

The password to open your digital e-Aadhaar PDF consists of 8 characters: The first 4 letters of your Name in CAPITAL letters, followed by your Year of Birth (YYYY). For example, if your name is SURESH KUMAR and your birth year is 1992, your password is SURE1992.

1) Visit myaadhaar.uidai.gov.in. 2) Click 'Order Aadhaar PVC Card'. 3) Enter your 12-digit Aadhaar Number or 28-digit EID and captcha. 4) Authenticate via OTP sent to your registered (or non-registered) mobile number. 5) Pay ₹50 online (includes printing, GST, and Speed Post delivery). 6) Track the Service Request Number (SRN) until doorstep delivery.

What is Baal Aadhaar and when are biometrics updated?

Baal Aadhaar is a blue-colored Aadhaar card issued to children under 5 years of age based on their birth certificate and parent's Aadhaar (without capturing biometrics). It requires two Mandatory Biometric Updates (MBU): 1) At age 5 (capturing fingerprints, iris, and photo), and 2) At age 15. Both MBUs are 100% free of charge at any Aadhaar Seva Kendra.

What is Masked Aadhaar and why should I use it?

A Masked Aadhaar is a legally valid digital copy where the first 8 digits of your Aadhaar number are hidden as 'XXXX-XXXX', displaying only the last 4 digits along with your photo and QR code. It is recommended for hotel check-ins, KYC, and identity proof to prevent Aadhaar number misuse while maintaining full verification validity.

Can I update my Aadhaar address online without visiting a center?

YES! Log into myaadhaar.uidai.gov.in using your Aadhaar number and OTP, select 'Address Update', choose 'Update Address Online', upload a valid address proof (Electricity bill, Bank statement, Rent agreement, or Head of Family HOF consent), pay the ₹50 fee, and track the URN until approved.
