Your mobile number has become an important part of using many Aadhaar-related online services. From OTP-based authentication to accessing certain government and financial services, having an active mobile number registered with Aadhaar can make digital verification much easier.

But what happens if the mobile number linked with your Aadhaar is no longer active, you have lost the SIM, or you have permanently switched to another number?

In such a situation, you should consider updating the mobile number registered with Aadhaar. Unlike some Aadhaar services that can be completed online, changing a registered mobile number generally requires identity verification through an authorized Aadhaar service facility.

Here's what Aadhaar holders should know.

Why Is Your Aadhaar-Linked Mobile Number Important?

An Aadhaar-registered mobile number is commonly used to receive one-time passwords for Aadhaar authentication and various digital services.

If your old number has been disconnected or you no longer have access to it, you may face difficulties completing OTP-based verification.

This can become inconvenient when accessing services that depend on Aadhaar authentication.

Keeping your active mobile number registered with Aadhaar can therefore help prevent problems later.

Can You Change Your Aadhaar Mobile Number Online?

One of the biggest questions Aadhaar holders have is whether the registered mobile number can simply be changed online from home.

The mobile-number update process requires appropriate identity authentication. Aadhaar holders may need to visit an authorized Aadhaar enrolment or update facility to complete the process.

This requirement also provides an additional layer of protection against someone attempting to change the registered number without authorization.

What If You No Longer Have the Old Mobile Number?

Losing access to the old number doesn't necessarily mean you cannot update your Aadhaar.

This is particularly useful for people whose old SIM has been permanently disconnected or lost.

Visit an authorized Aadhaar update facility and request that the active mobile number be registered with your Aadhaar. Follow the prescribed identity-verification procedure at the centre.

How to Update Your Mobile Number in Aadhaar

The basic process is straightforward.

Visit an authorized Aadhaar enrolment/update centre and request a mobile-number update. Provide your Aadhaar details and the new mobile number you want registered.

Complete the required authentication or verification process and pay the applicable official fee, if required.

After submitting the request, keep the acknowledgement or update request details safely. These can help you track the request later.

How Long Does the Update Take?

The new number may not become active in Aadhaar records immediately after submitting the request.

UIDAI processes update requests after the required verification. Processing time can vary, so Aadhaar holders should track their request rather than assuming that the change has been completed instantly.

Once the update is processed successfully, the newly registered mobile number can be used for applicable OTP-based Aadhaar services.

How Can You Check Whether Your Number Is Linked?

If you aren't sure whether your current mobile number is registered with Aadhaar, use UIDAI's official Aadhaar services to check the available verification options.

This can be particularly useful if you haven't used Aadhaar OTP authentication for a long time or have changed mobile numbers several times.

Checking the status before you urgently need an Aadhaar-based service can save time later.

Do You Need a New Aadhaar Card After Changing the Number?

Updating your registered mobile number does not mean that you are being issued a new Aadhaar number.

Your 12-digit Aadhaar number remains the same.

The change simply updates the contact information associated with your Aadhaar record. You don't need to apply for another Aadhaar number because your SIM or mobile number has changed.

Be Careful of Aadhaar Update Scams

Aadhaar-related services are also frequently used as bait in phishing and fraud attempts.

You may receive calls or messages claiming that your Aadhaar will be blocked unless you immediately update your mobile number through a provided link.

Avoid clicking suspicious links or installing unknown applications.

Most importantly, never share an Aadhaar OTP, UPI PIN, banking password or card credentials with someone claiming to be an Aadhaar official.

Use only official UIDAI channels and authorized Aadhaar service facilities for updates.

Why You Shouldn't Wait Until an Emergency

Many people discover that their old mobile number is still linked with Aadhaar only when they urgently need an OTP.

At that point, completing an Aadhaar-related verification can become unnecessarily difficult.

If you have permanently stopped using your Aadhaar-registered number, updating it in advance is a sensible step.

The Bottom Line

If the mobile number registered with your Aadhaar is no longer active, updating it can help you continue using OTP-based Aadhaar services without unnecessary interruptions.

You generally need to complete the prescribed verification process through an authorized Aadhaar update facility rather than simply replacing the number online yourself.

Keep your acknowledgement after submitting the request, check the update status and use only official UIDAI services. Most importantly, never share Aadhaar OTPs or financial credentials with anyone offering to “activate” or “update” your Aadhaar instantly.
