How to Verify Your Mobile Number and Email Linked to Aadhaar: Complete 2026 Guide
Verifying your mobile number and email linked to Aadhaar ensures seamless access to government services, banking, and OTP-based authentications worldwide. This free UIDAI process takes under 5 minutes online, preventing issues like failed e-KYC or missed updates for Indian residents and NRIs.
Why Verification Matters
Aadhaar’s 12-digit ID powers over 1,000 services, from PAN linking to UPI. An unverified or outdated mobile/email blocks OTPs for Aadhaar Paperless eSign, DBT schemes, or IRCTC bookings. In 2026, with digital India pushing Aadhaar-PAN 2.0, confirming details avoids penalties and secures privacy against fraud.
Globally, expats in UAE, USA, or UK use it for remittances via apps like PhonePe. Regular checks align with UIDAI’s mandate for active contacts.
