Aadhaar card update guide: Changed your mobile number? Here’s how to update it

UIDAI mandates in-person visits to Aadhaar Seva Kendras for mobile number updates due to required biometric verification. Linking the correct mobile number is crucial for accessing various services like government subsidies and banking, which rely on OTP-based verification. Appointments can be booked online, and updates take 2-4 weeks, costing Rs 50 unless done with biometric updates.
