How to Change the Mobile Number in Aadhaar (Aadhar)?
The surest way is an Aadhaar centre: no document, your fingerprint or iris proves it's you, ₹75, done the same day. If you still get SMS on your old number, you can also try UIDAI's Aadhaar App (OTP, face scan, ₹75), but in our experience it works only about half the time. OTPs usually start on the new number within 1–2 days.

How do you check which mobile number is linked?
Do this first; you may not need an update at all. At our counter we use Verify Email/Mobile Number on myAadhaar.
- Open myaadhaar.uidai.gov.in → Verify Email/Mobile Number
- Enter your Aadhaar number and the mobile number to check
- Type the captcha → an OTP comes to that number
- Confirmed as linked?No: update your mobile
- No update needed
Two more clues: UIDAI's Check Aadhaar Status page (Aadhaar number + captcha) may show the last 4 digits of the registered mobile, and the QR code on your e-Aadhaar holds a masked version of it.
Which way can you update your mobile number?
Answer up to three questions. You'll get the one route that works for you.
| Your situation | Where to update |
|---|---|
| Old number lost or closed | Aadhaar centre (₹75) |
| No number ever linked | Aadhaar centre (₹75) |
| Old number works + smartphone | Aadhaar App (₹75), or a centre |
| No smartphone, or face scan keeps failing | Aadhaar centre (₹75) |
How do you update your mobile at an Aadhaar centre?
Find a centre
YouCentre / UIDAIPayment / slip
- Find a centre. Use the official locator. Booking an appointment is free and saves queue time.
- Tell the operator you want to update your mobile number. Give your Aadhaar and the new number. No document is needed.
- Give your fingerprint or iris. This confirms your identity, so you don't need the old number.
- Pay ₹75 and check the slip. The acknowledgement slip carries the number you use to track the request. Check the new number on it before leaving.
- Wait for OTPs on the new number. In our experience they start within 1–2 days; UIDAI allows up to 30.
- Find a centre (optional: book a free appointment)
- Carry your Aadhaar and the new phone
- Operator enters the new number
- Fingerprint or iris matched?No: try other fingers or iris; ask about a biometric update
- Pay ₹75 → check the new number on the slip
- OTPs on the new number, usually within 1–2 days
- Which centres can do it? Aadhaar Seva Kendras, bank and post office Aadhaar centres, and CSCs that run an authorised Aadhaar centre. A normal CSC or cyber café can only print, download and order PVC cards; it can't change your mobile.
- Appointments: centres listed on UIDAI's booking site take online appointments; others are walk-in only.
- Timings: Aadhaar Seva Kendras usually open on Sundays too and close on only about 10 holidays a year (26 January, 15 August, 2 October and a few more). The centre we visit works 9:30 am–1 pm and 2–5:30 pm; don't arrive at lunchtime.
Read the slip before you walk away. A wrong digit means paying ₹75 again.
How do you update your mobile in the Aadhaar App?
Only if your current linked number still receives SMS. In our experience the app succeeds in roughly half of the cases; the face scan is the usual reason it fails. More on the new Aadhaar App.
Open the Aadhaar App and choose Update mobile number
YouUIDAIOTP / payment
- Open the Aadhaar App and choose Update mobile number. Use UIDAI's official Aadhaar App. mAadhaar has been removed from the Play Store.
- Type the new mobile number and request the OTP. Check every digit before you continue.
- Enter the 6-digit OTP(s). One OTP comes to the new number. If a different number is linked in the app, the current number gets one too.
- Complete the face scan. Good light, phone at eye level, face fully visible.
- Pay ₹75. Pay only inside the official app.
- Save your SRN and track it. UIDAI says app updates can take up to 30 days. Until then, OTPs still go to the old number.
- Aadhaar App → Update mobile number → type the new number
- OTPs received on the new (and current) number?No: use a centre
- Face scan passed?Failed twice: use a centre
- Pay ₹75 in the app
- Screenshot the SRN
- New number active, within up to 30 days
Open UIDAI's Aadhaar App
Install it only from the official store listing published by UIDAI. Register with your Aadhaar, OTP and face scan if you haven't yet.
Choose Update mobile number and enter the new number
If the option is missing: update the app to the latest version and look under Services.
Enter the OTPs
The new number always gets an OTP. If the number linked in the app is different, that number gets one too.
If you can't get the OTP on the old number: the app route won't work. Use a centre.
Complete face authentication
If it keeps failing: try daylight, remove glasses, keep still. If your Aadhaar photo is very old (for example taken as a child), a centre is easier.
Pay ₹75 and save the SRN
You'll know it worked when you see a Service Request Number (SRN). Screenshot it.
Can a postman update your mobile at home?
Partly. India Post Payments Bank (IPPB) lists Aadhaar mobile update for ₹75 at selected post offices, and free child enrolment at a few. In our team's experience IPPB postmen also come to the door for mobile updates. IPPB's own page does not list the children's mandatory biometric update. 155299 is IPPB's general contact line, not a booking line. More on Aadhaar services at home (IPPB).
In our experience booking is unreliable: after a request the postman often doesn't come, or comes late. If you need it soon, a centre is faster.
How much does it cost, and how long does it take?
| What you do | Fee | Note |
|---|---|---|
| Mobile update at a centre | ₹75 | No document. Same fee at every centre. Work out other fees with the fee calculator |
| Mobile update in the Aadhaar App | ₹75 | Needs OTP on the current linked number and a face scan |
| Mobile update together with a biometric update (photo, fingerprints, iris) | ₹0 extra | You pay only the biometric fee of ₹125; name, address, mobile and email changes in the same visit are included |
| Email update in the Aadhaar App | Free | Until 31 Dec 2026, then ₹75 |
| Email update at a centre | ₹75 | Free if done together with a biometric update |
| Appointment booking | Free | bookappointment.uidai.gov.in |
Anyone charging more than ₹75 for a mobile update is overcharging. Complain on 1947 or [email protected]. News reports of a 2023 government reply say that, if proven, the operator is suspended and the registrar fined ₹50,000. Old rates like ₹50 or ₹100 seen in old FAQs are outdated.
What changes after you update your Aadhaar mobile?
| Question | Answer from our counter |
|---|---|
| Does my bank or UPI number change too? | No. Bank OTPs and UPI keep using the number registered with the bank. Update it at your bank separately. |
| Can a family member's number be linked? | Yes, a father's, mother's or child's SIM can be linked without problems. All your Aadhaar OTPs will then go to their phone. |
| How many Aadhaar numbers can share one mobile? | In our experience up to 9. |
| Do I need the new number for PAN–Aadhaar linking? | Yes, if you still have to link: the e-filing portal sends the OTP to your Aadhaar mobile. Update it first, then see link PAN with Aadhaar. |
| When can I download e-Aadhaar with the new number? | Once OTPs arrive on it, usually after 1–2 days. How to download e-Aadhaar |
Can you update your email at the same time?
Yes. In the Aadhaar App, email update is free until 31 December 2026 (normally ₹75). At a centre it's ₹75 on its own, or free when done with a biometric update. In our experience a linked email also lets you recover a lost Aadhaar number with your name and email.
What can go wrong, and how do you fix it?
| Your situation | What it usually means | What to do |
|---|---|---|
| Old number lost, SIM closed | You can't receive the OTP the app needs | Go to any Aadhaar centre. Your biometric replaces the old OTP; it's done the same day. |
| Face scan keeps failing in the app | Light, angle, or an old enrolment photo | Try daylight and remove glasses. If it fails twice, use a centre. |
| No "update mobile" option in the app | Old app version, or no number ever linked | Update the app. First-time registration is centre-only. |
| Paid, but OTPs still go to the old number | The update is still processing | Wait: usually 1–2 days after a centre update, up to 30 days in the app. Track with the number on your slip or SRN. |
| Over 30 days and still "in progress" | Stuck or held for checks | Check update status and rejection fixes, then call 1947 with your slip number or SRN and ask for a grievance number. |
| Fingerprint not matching at the centre | Worn or dry fingers | Try other fingers or the iris scan. If nothing matches, ask about a biometric update (₹125, includes the mobile change). See fingerprints not matching. |
| Wrong new number on the slip | Typo at the counter | Ask the operator to correct it before you leave. |
Updating your Aadhaar mobile from abroad
- If your Indian number still receives SMS (roaming), the Aadhaar App route may work from abroad.
- If the Indian SIM is closed, you need an Aadhaar centre during your next India visit. Book an appointment before you travel; it's free.
- Aadhaar OTPs are sent to Indian mobile numbers. Keep one Indian number active if you use Aadhaar services often.
Region not right?
Mobile-update scams we see
- Fake links by SMS or WhatsApp promising "update your Aadhaar mobile from home". Use only the official app or a centre. More on Aadhaar fraud and scams.
- Calls asking for your OTP or Aadhaar number ("your Aadhaar will be blocked"). Hang up. UIDAI never asks for an OTP on a call.
- Fake apps or screen-sharing apps (AnyDesk-type) that a caller asks you to install. Never install them.
Frequently asked questions
Can I update my Aadhaar mobile number online without the old number?
No. The app needs an OTP on the current linked number. Without it, visit any Aadhaar centre, where your fingerprint or iris verifies you. It's done the same day.
How much does it cost to change the mobile number in Aadhaar?
₹75, at a centre or in the app. It costs nothing extra if done together with a biometric update (₹125).
How long does a mobile update take?
At a centre, in our experience OTPs start on the new number within 1–2 days. In the app it can take up to 30 days. That is UIDAI's own limit for app requests.
Do I need any document to update my mobile number?
No. At a centre your fingerprint or iris proves your identity; in the app, OTP and face scan do.
Can I register a mobile number for the first time in the app?
No. First-time registration is done at an Aadhaar centre.
Can my father's or son's number be linked to my Aadhaar?
Yes, a family member's number can be linked without problems. Your Aadhaar OTPs will then go to their phone, so choose someone you see often.
Will my bank get the new number automatically?
No. Banks and UPI use the number registered with the bank. Update it there separately.
Can I update my mobile at a CSC or cyber café?
Only at a CSC that runs an authorised Aadhaar centre. A normal CSC or cyber café can print, download and order PVC cards, but can't change your mobile.
Is the mAadhaar app still used for updates?
No. mAadhaar has been removed from the Play Store. Use UIDAI's new Aadhaar App.
Bottom line
Keep a working mobile on your Aadhaar; almost every Aadhaar service depends on its OTP. One centre visit, no documents and ₹75 fixes it, usually with OTPs on the new number within a day or two. For help, UIDAI's free helpline is 1947.
