Direct answer. UIDAI's citizen services include: Aadhaar enrolment, mAadhaar app, online address/name/DOB updates, Aadhaar Lock (anti-fraud), eKYC for paperless verification, and PVC Aadhaar card delivery. Most via uidai.gov.in OR mAadhaar app.

• Get Aadhaar — enrolment at Aadhaar Seva Kendra (free, ~1 hour).
• mAadhaar app — digital Aadhaar in your phone.
• Aadhaar Update online: mobile, address (with valid OVD). ₹50.
• At Seva Kendra: name, DOB, biometrics. ₹50–100.
• Aadhaar Lock — biometric/demographic lock to prevent fraud. Free.
• eKYC — paperless KYC for any service. Free.
• PVC Aadhaar card — printed plastic card via post. ₹50.
• Verify Aadhaar — verify any Aadhaar offline (via your phone).

1. mAadhaar app → “Lock Biometrics” → enable.
2. Now: no biometric authentication can use your Aadhaar (eKYC, payment, etc.).
3. Unlock momentarily when needed (for KYC) → re-lock immediately.

If your Aadhaar gets misused (digital arrest scam, phishing, etc.), this is your first line of defence.
