How to check which mobile number is linked with Aadhaar online? Follow these steps to find out

The Aadhaar card is one of the most important identity documents in India and is required for accessing several government and financial services. A mobile number registered with Aadhaar is particularly important as it allows users to receive One-Time Passwords (OTPs) for authentication, verification and other Aadhaar-related services.

However, many people may forget which mobile number they registered with their Aadhaar card, particularly if they have changed their SIM card or use multiple phone numbers. The Unique Identification Authority of India (UIDAI) provides online facilities that allow residents to verify their registered mobile numbers.

How to check which mobile number is linked with Aadhaar online?

UIDAI provides two ways to help residents identify or verify the mobile number registered with their Aadhaar.


The first method allows users to check the last three digits of their registered mobile number, while the second helps them verify whether a particular phone number is linked to their Aadhaar.

Method 1: How to find the last three digits of your Aadhaar-linked mobile number

If you do not remember which mobile number you provided during Aadhaar enrolment or your latest update, you can use the UIDAI portal to check its last three digits.

Follow these steps:

1. Visit the official UIDAI website at https://uidai.gov.in/.

2. Go to the My Aadhaar section.

3. Navigate to Aadhaar Services and select Verify an Aadhaar Number.

4. Enter your 12-digit Aadhaar number in the required field.

5. Enter the captcha code displayed on the screen.

6. Submit the details to verify your Aadhaar.

7. Check the information displayed on the screen for the last three digits of your registered mobile number, if available.

You can compare these digits with the mobile numbers you currently use to identify which one may be registered with your Aadhaar.

Method 2: How to verify whether your mobile number is linked with Aadhaar

If you have a few mobile numbers and want to find out which one is registered with your Aadhaar, you can use UIDAI's Verify Email/Mobile Number service.

Here is how to do it:

1. Visit the official My Aadhaar portal.

2. Look for the Verify Email/Mobile Number option under Aadhaar Services.

3. Select the mobile number verification option.

4. Enter your 12-digit Aadhaar number.

5. Type the mobile number you want to verify.

6. Enter the captcha code shown on the screen.

7. Click on the Submit or Verify option.

The portal will display whether the mobile number you entered matches UIDAI's records.

If the number is registered, you will receive a confirmation message stating that the mobile number has already been verified with UIDAI's records. If it does not match, the portal will notify you accordingly.

What if your mobile number is not linked with Aadhaar?

If the UIDAI portal indicates that your mobile number is not registered with Aadhaar, you may need to update your contact details.

For this, visit your nearest Aadhaar Enrolment or Update Centre. You can request the operator to register a new mobile number or replace your existing registered number.

Follow these steps:

1. Locate your nearest Aadhaar centre through the official UIDAI website.

2. Visit the centre and request a mobile number update.

3. Provide your Aadhaar details and complete the required verification.

4. Pay the applicable update fee, if any.

5. Collect the acknowledgement slip containing your Update Request Number (URN).

6. Use the URN to track the status of your update request.
