Aadhaar Mobile Number Change: What to Do If Your Old Number Is Lost

Here's a situation more common than you'd think: you switched SIM cards two years ago, your old number got recycled by the telecom company, and now you can't receive the OTP your bank, your scholarship portal, or your new SIM activation keeps asking for. Your Aadhaar is still linked to a number that isn't yours anymore.

The reassuring part is that you don't need access to that old number at all to fix this. This guide covers everything you need to know about changing your mobile number on Aadhaar in 2026 — why it works differently from other Aadhaar updates, exactly where you need to go, what to carry, the fee, and how long it actually takes.

Why You Can't Change Your Aadhaar Mobile Number Online

Most Aadhaar fields — address, name, date of birth — can be updated through the myAadhaar self-service portal using an OTP sent to your registered number. Mobile number and email ID are the exception. UIDAI requires biometric authentication for these two fields specifically, which means you have to visit a physical centre. There's no workaround for this, and no amount of document upload replaces it.

This is actually good news if your old number is lost: you were never going to need it anyway. The update doesn't depend on receiving an OTP on the number you're replacing.

Where to Go: Aadhaar Seva Kendra or CSC

You have two options, and both involve an in-person visit:

• An official Aadhaar Seva Kendra, run directly by UIDAI
• A CSC (Common Service Centre) or Sewa Kendra authorised to handle Aadhaar updates — see our guide on how a CSC actually works if you're curious what these centres handle beyond Aadhaar

Not every CSC offers biometric Aadhaar updates — some only handle demographic (OTP-based) changes. Use our CSC Centre Locator to find one near you that specifically lists Aadhaar enrolment/update services, or call ahead before you go.

What to Carry

• Your Aadhaar number (the physical card or e-Aadhaar printout isn't compulsory, but it speeds things up)
• One original photo ID — your Aadhaar itself usually works, but carry a backup like a voter ID, driving licence, or passport just in case
• The new mobile number you want linked — make sure it's active and in your possession, since it needs to receive a confirmation SMS after the update

You don't need any proof of address or proof of identity document specifically for a mobile number change — this is purely a biometric verification, not a document-based one.

How to Change Your Aadhaar Mobile Number — Step by Step

Step 1: Locate an Aadhaar Seva Kendra or an Aadhaar-update-enabled CSC near you.

Step 2: Fill the Aadhaar Update/Correction Form available at the centre, or ask the operator to fill it for you — tick "Mobile Number" as the field you're updating.

Step 3: Enter your new mobile number clearly on the form.

Step 4: Provide your biometrics — fingerprint and/or iris scan, whichever the centre's device captures.

Step 5: Pay the update fee (around ₹50) and collect your acknowledgement slip with the URN (Update Request Number).

Step 6: Keep the slip. You'll use the URN to track your request and, if needed, raise it with UIDAI's helpline.

Aadhaar Mobile Number Update Fee

The standard fee is around ₹50, same as most other demographic updates. Some centres may add a small service charge on top — ask before you start the process so there's no surprise at the counter. Fees may change, so confirm the current amount at the centre or on the UIDAI portal before paying.

How to Check Your Update Status

1. Go to myaadhaar.uidai.gov.in and select "Check Aadhaar Update Status."
2. Enter your Aadhaar number and the URN from your acknowledgement slip.
3. Enter the captcha and submit.
4. Your status will show as In Progress, Rejected, or Updated Successfully.

Once it shows updated, you'll typically get a confirmation SMS on the new number — that's your real-world proof the change went through, separate from the online status check.

How Long Does It Take?

Most mobile number updates process within a few days, sometimes less. UIDAI's outer SLA is up to 90 days, but that's rarely how long a straightforward biometric update actually takes. If your status is still pending well beyond a couple of weeks, contact UIDAI's helpline with your URN.

Common Problems People Run Into

• Biometric mismatch or failed capture — worn fingerprints (common in manual labour, older age groups) can slow things down; the centre may try iris scanning instead.
• Entering the new number incorrectly on the form — double-check every digit before the operator submits it.
• Assuming it can be done online — this is the single most common mistake; no portal, app, or OTP-based route updates this field.
• Not receiving the confirmation SMS — if your status shows "Updated" but you got no SMS, check for network issues on the new number before assuming something's wrong.

Why a Correct Mobile Number Matters Beyond Aadhaar

Your Aadhaar-linked mobile number is what receives OTPs for bank KYC, new SIM activations, and increasingly, self-service registration on government portals — e-Shram registration is a good example where an Aadhaar-linked number makes the whole process faster. Scholarship applications, PM-Kisan-type scheme disbursals, and income certificate or ration card application tracking also rely on this number working correctly. Even PAN-Aadhaar linking checks send their confirmation to whatever mobile number Aadhaar currently has on file. If you're already updating it, this is as good a time as any to also check your Aadhaar address and name are current — see our complete Aadhaar update and correction guide for every field you can fix.
