How to Link Aadhaar Card with Mobile Number Online – Step by Step Process, Re-verifying & FAQs

The significance of Aadhaar has grown many folds ever since the Government of India decided to link it with a range of documents and services, including the mobile number.

The government has made it mandatory to link Aadhaar with your mobile number to weed out illegal mobile numbers used for criminal activities. However, the process has been simplified to help you seed your mobile number without hassles.

Two scenarios will arise when you decide to link your Aadhaar with a mobile number: Either you already have an updated mobile number, or your Aadhaar has no mobile number attached to it. The process will be starkly different in either case.

Linking the mobile number to Aadhaar for the first time (Offline method)

Unfortunately, this process cannot be done online. You will have to visit the nearest Aadhaar centre.

• Collect the Aadhaar update form from the nearest centre.
• Enter the accurate information along with your mobile number. Alternatively, you can also download the form from UIDAI website.
• Mention on the form that only your phone number needs to be updated. Submit it to the concerned office along with a photocopy of your Aadhaar card and one photo ID proof such as PAN card, voter id, passport, etc.
• The next step will be the verification of your thumb impression and biometrics. It will be matched with the ones recorded during the Aadhaar application process.
• The officer will give you an acknowledgement slip. You can expect the update to take place within five days. However, it could even take up to 10 days as per UIDAI website.
• You can track the status of your Aadhaar update using the Update Request Number (URN) provided in the acknowledgement slip.

Here is a guide to linking your Aadhaar card to your mobile number online without visiting an Aadhaar Seva Kendra:

5. Once you fill in all the necessary fields, click on the ‘Request OTP’ button.

Verifying SIM using Aadhaar(OTP Method):

After much deliberation, UIDAI has decided to allow linking Aadhaar with a mobile number via OTP without providing your biometrics to the telecom service provider.

• Most service providers have direct links for the process. You can enter your mobile number on your service provider’s website.
• You will get an OTP on your registered number which you will have to enter on the website.
• Next, you will have to check the ‘consent box’ that will appear after you enter your Aadhaar number.
• The telecom service providers will then request UIDAI for OTP. If your number is updated, you will receive an OTP from UIDAI.
• You will again get a ‘consent message’ that needs to be checked. You will have to enter the received OTP to complete the verification process.

Finally, you will receive a message stating that your mobile number has been re-verified.

Alternatively, users can also resort to the Interactive Voice Response System (IVRS) provided by your telecom service provider. The process will be similar to the online procedure except for the fact that the voice-based system will guide you in the process. The Government of India has also directed the telecom operators to ensure agent-assisted verification for the differently-abled citizens.

The Aadhaar mobile linking is expected to eliminate all the fake mobile numbers procured on forged documents.

What are the documents required to link your Aadhaar?

No document is needed to link the mobile number with the Aadhaar. However, you must carry the Aadhaar card when visiting the Aadhaar Seva Kendra.
