How to update or link your mobile number in Aadhaar (2026)
If your old Aadhaar mobile still works, you can change it in the new Aadhaar app: register with the old number, enter the new one, and verify with OTP. If the old number is lost/inactive or you are adding a number for the first time, visit an Aadhaar Seva Kendra / enrolment centre (or use India Post Payments Bank’s doorstep service where available). No documents are needed; the centre fee is ₹75.

Why your Aadhaar mobile number matters
Almost every OTP — PAN–Aadhaar linking, UAN activation, DigiLocker, scheme e-KYC, bank eKYC — goes to the mobile number in Aadhaar, not to the number in your bank or PAN. An old or inactive number is the single most common reason people get stuck.
Option 1 — In the Aadhaar app (old number still works)
- Install the official Aadhaar app and register with your Aadhaar and the current Aadhaar mobile (OTP).
- Go to update mobile number, enter the new number and verify it with the OTP sent to the new number.
- Complete face authentication if asked, and submit. Note the request number and track it in the app.
Option 2 — At an Aadhaar centre (old number lost or first-time)
- Find a centre on uidai.gov.in (Locate Enrolment Centre) or book an appointment at an Aadhaar Seva Kendra.
- Carry only your Aadhaar (number or card). Give your new mobile number to the operator.
- Authenticate with your fingerprint or iris. Pay ₹75 and collect the acknowledgement slip with URN.
- The number is usually updated within a few days to a few weeks; you get an SMS when it is done.
India Post Payments Bank (IPPB) offers Aadhaar mobile-number updates through postmen at your doorstep in many areas. Ask at your local post office.
Check which number is registered
