Aadhaar Mobile Number Update & Link (2026) — How to Change It

Your Aadhaar-linked mobile number is the key to almost everything — every OTP for banking, downloading Aadhaar, ration e-KYC, subsidies and more goes to it. If it’s wrong, outdated, or not linked, half of these services simply won’t work. This guide shows you how to update or link your mobile number in Aadhaar in 2026, why it matters so much, the exact process, what you need, and how to check which mobile is currently linked.

Why Your Aadhaar Mobile Number Is So Important

The mobile number linked to your Aadhaar receives the OTP for a huge range of services: downloading e-Aadhaar, the free Aadhaar update, ration e-KYC, bank KYC, LPG subsidy, and many government services. If your linked number is old or wrong, all of these break — which is why updating it is one of the most useful things you can do.

Can You Update the Mobile Number Online?

Here’s the honest answer: updating your Aadhaar mobile number generally requires a visit to an Aadhaar enrolment/update centre. Because it’s a security-sensitive change, it usually needs biometric verification in person — you can’t simply change it from home. Some steps can be started online, but the mobile update itself is done at a centre.

How to Update/Link Your Aadhaar Mobile Number

Visit an Aadhaar enrolment/update centre (find one via the official UIDAI locator).
Fill the update request for mobile number.
Provide the new mobile number you want linked.
Complete biometric verification (fingerprint/iris) to confirm identity.
Pay the small official fee and collect your acknowledgement slip.
Wait for the update to reflect, then test an OTP.

Tip: you usually don’t need a document just to update the mobile number — biometric verification is the key step. Confirm current requirements at the centre.

How to Check Which Mobile Is Linked to Aadhaar

Not sure if your number is linked, or which one? UIDAI provides official ways to verify whether a mobile/email is registered with your Aadhaar (without revealing the full number). Use the official UIDAI verification option. If no number is linked — or it’s an old one — get it updated at a centre.

Common Problems This Fixes

“OTP not received” when downloading Aadhaar or doing e-KYC.
Ration e-KYC failing — see ration e-KYC.
LPG subsidy / bank KYC issues tied to Aadhaar OTP.
Can’t use online government services that need Aadhaar OTP.

Stay Safe

Only update at official Aadhaar centres — never share OTP or pay “agents” to change it remotely.
UIDAI never calls asking for your OTP — that’s always a scam.
Keep your number active so services keep working.

Once your mobile is correctly linked, keep the rest current too — see free Aadhaar update and Aadhaar-PAN link. Processes and fees are set by UIDAI and can change — confirm at the centre or official portal.

Frequently Asked Questions

How do I update my mobile number in Aadhaar?▼

Updating your Aadhaar mobile number generally requires visiting an Aadhaar enrolment or update centre, because it is a security-sensitive change that needs biometric verification in person. At the centre, fill the update request for mobile number, provide the new number you want linked, complete biometric verification such as fingerprint or iris scan to confirm your identity, pay the small official fee, and collect your acknowledgement slip. The update then reflects after some time, after which you can test that OTPs arrive. You usually do not need a supporting document just to update the mobile number.

Can I change my Aadhaar mobile number online?▼

Generally no - updating the mobile number linked to your Aadhaar requires an in-person visit to an Aadhaar enrolment or update centre, because it needs biometric verification for security reasons. You cannot simply change it from home, since that would be a fraud risk. While some Aadhaar services can be accessed online, the mobile number update itself is done at a centre. This is important because your linked mobile receives the OTP for many services, so keeping it current is essential - but the update must be done through the secure, in-person process.

Why is my Aadhaar mobile number important?▼

Your Aadhaar-linked mobile number receives the OTP for a huge range of services, including downloading your e-Aadhaar, the free Aadhaar update, ration card e-KYC, bank KYC, LPG subsidy verification and many government services. If your linked number is old, wrong or missing, all of these OTP-based services stop working, which can block you from important benefits and verifications. That is why keeping your Aadhaar mobile number correct and active is one of the most useful things you can do to ensure your banking, schemes and government services function smoothly.

How do I check which mobile number is linked to my Aadhaar?▼

UIDAI provides official ways to verify whether a mobile number or email is registered with your Aadhaar, without revealing the full number, through its official verification option. This lets you confirm whether your current number is linked or check if the linked number is an old one. If you find that no number is linked, or that it is outdated, you should get it updated at an Aadhaar enrolment centre through the in-person biometric process. Always use only official UIDAI channels for this check, and never share your Aadhaar OTP with anyone.

What problems does updating my Aadhaar mobile number fix?▼

Updating your Aadhaar mobile number fixes many common issues that stem from not receiving OTPs. These include 'OTP not received' errors when downloading your Aadhaar or doing e-KYC, ration card e-KYC failing, LPG subsidy or bank KYC problems tied to Aadhaar OTP, and being unable to use online government services that require Aadhaar OTP verification. Because so many services depend on the OTP reaching your linked mobile, correcting an outdated or missing number restores access to all of them. It is a simple fix that resolves a surprisingly wide range of everyday service problems.
