The mobile number linked to your Aadhaar is the single most important detail to keep current — it's the OTP destination for nearly every Aadhaar-based KYC check (PAN linking, EPFO login, e-Sign, DigiLocker, banking).
Unlike most other Aadhaar updates, the mobile change cannot be done online. UIDAI requires biometric verification to prevent identity theft via SIM swap. You have to visit a UIDAI-authorised enrolment centre, an authorised bank/post office Aadhaar desk, or a Common Service Centre with biometric equipment.
Once linked, the new number takes a few working days to become active across the UIDAI ecosystem.
Eligibility
- You hold an Aadhaar.
- You can visit a UIDAI-authorised enrolment / update centre in person.
- You can provide a biometric (fingerprint or iris) for verification.

What happens after applying
- 1

You visit a UIDAI-authorised enrolment or update centre in person with your Aadhaar.
- 2
Biometric authentication
The operator captures your fingerprint or iris to verify you are the Aadhaar holder. No OTP is used for this step.
- 3
Update request submitted
The operator enters your new mobile number in the UIDAI system and generates a URN slip.
- 4
UIDAI processing
UIDAI processes the update in its backend. The new number is linked within a few working days.
- 5
Confirmation
An SMS is sent to both the old and new mobile numbers confirming the mobile update.
Common mistakes & rejection reasons
Visiting an unauthorised service centre
Why: Fraudulent operators may steal your biometric data. Only authorised UIDAI centres have the equipment and certification to process updates.
Fix: Always verify the centre on the official UIDAI locator at bhuvan.nrsc.gov.in/aadhaar/ before visiting.
Providing a number already linked to another Aadhaar
Why: UIDAI links one number to one Aadhaar by default. Using a number already linked to a different Aadhaar may cause a conflict or be rejected.
Fix: Use a fresh, unlinked SIM or check with the existing holder before using a shared mobile number.
Not saving the URN slip
Why: Without the URN, you cannot track whether the update was processed or raise a complaint if delayed.
Fix: Keep the paper slip. Note the URN in your phone. Track status on myAadhaar after a few days.
Assuming the update is instant
Why: The mobile update usually takes a few working days to propagate across UIDAI systems. OTP to the new number may not work immediately.
Fix: Wait 3–5 working days before testing the new number for OTPs. Track the URN to confirm completion.
Trying to link a landline number
Why: UIDAI only accepts a 10-digit mobile number. Landline numbers are not valid for Aadhaar OTP or registration.
Fix: Use a mobile SIM (not a landline) for the update.
Special situations
Both fingerprints and iris scans fail biometric verification▾
The operator may attempt multiple readings. If authentication fails completely (e.g., worn-out fingerprints, old age), the centre may escalate to the UIDAI Regional Office for exception handling.
Parent wants to link their mobile to a child's Aadhaar▾
Children under 18 can have a parent's mobile linked to their Aadhaar. The process is the same — the parent provides biometric for authentication and consents to the update.
Your biometrics are locked▾
Biometric lock applies to external authentication agencies, not to UIDAI enrolment centre operators. The centre should still be able to capture and verify your biometrics for the update.
You have no biometric — e.g., amputee or burn victim▾
UIDAI has exception procedures for people with physical conditions that prevent biometric capture. The enrolment centre should escalate to the UIDAI Regional Office with supporting medical documentation.
You lost your Aadhaar card and don't remember the number▾
The enrolment centre can look up your record using your name and DOB combined with biometric. Alternatively, retrieve your Aadhaar number from UIDAI using the 'Retrieve Lost UID / EID' option on myAadhaar.
Frequently asked questions
Can I update my Aadhaar mobile number online?▾
No. UIDAI requires biometric verification for mobile updates, so it must be done in person at an authorised centre.
How long does it take?▾
The new number is usually active for OTP and notifications within a few working days of submission.
Do I need an address proof to change the mobile number?▾
No. Only your existing Aadhaar and biometric verification are needed for a mobile update.
Can I link the same mobile to my child's Aadhaar?▾
Yes, parents can have a child's Aadhaar mobile linked to their own number until the child turns 18.
Is there a fee to update the mobile number on Aadhaar?▾
Yes. UIDAI charges a fixed fee at the enrolment centre. The exact amount may vary slightly by centre type (government centre, bank, or post office).
What if my fingerprints are not being recognised at the centre?▾
The operator typically tries multiple fingers and iris. If biometrics consistently fail, escalate to the UIDAI Regional Office — there are exception procedures for this.
How do I find an authorised Aadhaar enrolment centre near me?▾
Use the UIDAI locator at bhuvan.nrsc.gov.in/aadhaar/. Many bank branches and post offices also have authorised Aadhaar update desks.
Will I receive a confirmation once the mobile update is done?▾
Yes. UIDAI sends an SMS confirmation to both the old and new mobile numbers once the update is processed.
Can I update the mobile number at a Common Service Centre (CSC)?▾
Yes. Many CSCs are authorised for Aadhaar updates including mobile number changes. Verify the CSC's authorisation on the UIDAI locator.
What if the new mobile I want to register is already linked to another Aadhaar?▾
UIDAI may reject or flag the update if the number is already linked to a different Aadhaar. Use a number that is not currently linked to another Aadhaar.
Can I add a second mobile number to Aadhaar?▾
No. Aadhaar supports only one registered mobile number at a time. Updating the mobile replaces the previous number.
My Aadhaar mobile update was processed but OTPs are still going to the old number. Why?▾
After a successful update, it typically takes 24–48 hours for all UIDAI systems to sync. Try again after this window. If it persists beyond 5 days, check the URN status and raise a complaint.
Can I link a mobile number to Aadhaar during new enrolment?▾
Yes. If you are enrolling for Aadhaar for the first time, provide your mobile number during enrolment. It is registered at that point without needing a separate update.
What happens if I update to a wrong mobile number by mistake?▾
You would need to visit the enrolment centre again to correct it. The update process is the same — biometric verification and a new URN will be issued.
Is the mobile number linked to Aadhaar public or private?▾
UIDAI does not publicly disclose the mobile number linked to your Aadhaar. It is stored securely and used only for OTP authentication — it is not shared with third parties without your consent.
