How to Link Aadhaar With Mobile

Linking your Aadhaar card with your mobile number is a mandatory requirement under Indian government regulations aimed at enhancing security, reducing identity fraud, and ensuring accurate verification of telecom subscribers. As of recent directives from the Department of Telecommunications (DoT) and the Unique Identification Authority of India (UIDAI), all mobile connections must be authenticated using Aadhaar-based biometric or OTP verification. This process not only complies with legal norms but also safeguards your personal data from misuse, unauthorized porting, or illegal SIM duplication.

For millions of Indian citizens, linking Aadhaar with a mobile number is a straightforward digital procedure that can be completed in minutes. However, confusion often arises due to varying instructions across service providers, outdated online resources, or misinformation about required documents and methods. This comprehensive guide walks you through every step of the process — from preparation to confirmation — ensuring you complete the task correctly, securely, and without unnecessary delays.

Whether you’re a new subscriber activating a SIM card, an existing user whose connection was flagged for non-compliance, or someone managing mobile lines for family members, this tutorial provides clear, actionable, and up-to-date guidance. By the end, you’ll understand not only how to link Aadhaar with your mobile number but also why it matters, how to avoid common pitfalls, and what tools and resources are available to support you.

Step-by-Step Guide

Method 1: Online Linking via Service Provider Portal

The most convenient method for linking Aadhaar with your mobile number is through your telecom provider’s official website or mobile app. This method is ideal for users with internet access and a registered mobile number linked to their Aadhaar.

Begin by visiting your service provider’s official website. For example, if you are a Jio user, navigate to www.jio.com; for Airtel, go to www.airtel.in; for Vi (Vodafone Idea), visit www.myvi.in. Ensure you are on the legitimate domain to avoid phishing risks.

Look for a section labeled “Link Aadhaar,” “Aadhaar Verification,” or “KYC Update.” Click on it. You will be prompted to enter your 10-digit mobile number associated with the connection you wish to verify. After entering the number, click “Proceed.”

An One-Time Password (OTP) will be sent to your registered mobile number. Enter this OTP in the designated field to authenticate your identity. Once verified, you will be redirected to the Aadhaar authentication page.

On the Aadhaar portal interface, enter your 12-digit Aadhaar number. You will then be given two options: biometric authentication or OTP-based authentication. If you choose OTP, a second OTP will be sent to the mobile number registered with your Aadhaar (this may differ from your current telecom number). Enter this OTP to complete verification.

If biometric authentication is selected, you will be prompted to visit a nearby Aadhaar enrollment center or authorized kiosk. The staff will use a biometric scanner to match your fingerprint or iris with the UIDAI database. Once verified, your mobile connection will be linked automatically.

After successful authentication, you will receive a confirmation SMS from your service provider stating that your Aadhaar has been successfully linked. Keep this message for your records. You may also log back into your account dashboard to view the verification status under “My Profile” or “KYC Status.”

Method 2: In-Person Verification at Retail Store or Authorized Center

If you do not have access to the internet, are unable to receive OTPs, or encounter technical issues during online verification, visiting a physical store or authorized Aadhaar enrollment center is a reliable alternative.

Locate the nearest retail outlet of your telecom provider. Most branded stores (Jio, Airtel, Vi, BSNL) have dedicated KYC counters. Alternatively, you can visit a Common Service Center (CSC) or Aadhaar Seva Kendra. These centers are widely available in both urban and rural areas.

Carry the following documents:

• Your original Aadhaar card (physical or e-Aadhaar downloaded from uidai.gov.in)
• Your mobile SIM card
• A valid photo ID (if requested)

At the center, inform the executive that you wish to link your Aadhaar with your mobile number. They will use a handheld Aadhaar authentication device to scan your fingerprint or iris. The device connects directly to the UIDAI server in real time to validate your identity.

Once your biometric data matches the UIDAI records, the executive will initiate the linking process on their backend system. The system will then send a confirmation request to your mobile number. You may be asked to confirm via SMS reply (e.g., “YES” to a message from 51969 or your service provider’s shortcode).

The entire process typically takes less than 10 minutes. Upon completion, you will receive a printed receipt or digital confirmation. You should also receive an SMS from your service provider confirming the successful linkage.

Method 3: USSD Code Method (For Feature Phone Users)

For users without smartphones or internet access, the USSD (Unstructured Supplementary Service Data) method offers a simple, text-based solution. This method works on all GSM-enabled mobile phones, regardless of whether they are smartphones or basic feature phones.

Dial the following code from your mobile device: *145*1

and press the call button. This code is standardized across most major telecom providers in India, including Jio, Airtel, and Vi. After dialing, you will receive an automated voice prompt or SMS instructing you to enter your 12-digit Aadhaar number.

Enter your Aadhaar number using the keypad and press

. You will then receive an OTP on your registered mobile number. Enter this OTP as prompted. The system will validate your Aadhaar details with UIDAI’s database.

If your Aadhaar number is already linked to a different mobile number, you may be notified that the number is already registered. In such cases, you will need to contact your service provider to resolve the conflict or request de-linking from the previous connection.

Once verified, you will receive a confirmation message: “Your Aadhaar has been successfully linked with your mobile number.”

Method 4: Linking via UIDAI’s Official Website

While the primary responsibility for linking Aadhaar to mobile lies with telecom operators, UIDAI offers a supplementary portal for users to check the status of their linkage or initiate a request.

Visit the official UIDAI website at https://uidai.gov.in. Click on “My Aadhaar” in the top navigation bar, then select “Update Mobile Number” or “Check Aadhaar Status.”

If your mobile number is not registered with Aadhaar, you can update it by selecting “Update Mobile Number.” You will need to enter your Aadhaar number and receive an OTP on your current registered mobile (if any). After authentication, you can enter your new mobile number. This step ensures that future OTPs for mobile linking are sent to the correct number.

After updating your mobile number with UIDAI, return to your telecom provider’s portal and attempt the linking process again. This method is particularly useful if you recently changed your mobile number and the old one was previously linked to your Aadhaar.

Linking for Multiple Numbers

If you own multiple mobile connections under your name, each SIM must be individually linked to your Aadhaar. The process is identical for each number, but you must repeat the steps for every SIM card.

It is important to note that while one Aadhaar number can be linked to multiple mobile connections, each connection must be verified separately. Some service providers may limit the number of connections per Aadhaar to five, in accordance with DoT guidelines to prevent misuse.

Before initiating the process for additional numbers, ensure that your Aadhaar is not already linked to the maximum allowed connections. You can check this by visiting the UIDAI portal and selecting “Check Aadhaar Status.”

Linking for Minors and Guardians

For minors under the age of 18, Aadhaar linking must be done by a legal guardian. The guardian must provide their own Aadhaar details and proof of guardianship (such as a birth certificate or court order) during the verification process.

At retail stores, the guardian must be physically present with the minor and provide valid identification. Online methods require the guardian to log in using their own credentials and enter the minor’s Aadhaar number. The OTP will be sent to the guardian’s registered mobile number.

Once linked, the minor’s mobile number remains under the guardian’s responsibility until the child turns 18, at which point they may update the linkage to their own Aadhaar if they have one.

Best Practices

Verify Your Aadhaar Details Before Linking

Before initiating any linking process, ensure your Aadhaar details — including name, date of birth, gender, and mobile number — are accurate and up to date. Any mismatch between your Aadhaar records and your telecom provider’s data can cause verification failure.

To check your Aadhaar details, visit the UIDAI website and use the “Verify Aadhaar” feature. You can also download your e-Aadhaar, which displays all registered information. If you find discrepancies, update them immediately through the UIDAI portal or by visiting an enrollment center.

Use Only Official Channels

Never share your Aadhaar number, OTP, or biometric data with third-party websites, apps, or individuals claiming to assist with linking. Fraudsters often create fake portals or send phishing SMS messages mimicking official telecom brands.

Always verify the URL of the website you are using. Official portals will have HTTPS encryption and the correct domain name. Avoid clicking on links sent via unsolicited SMS or WhatsApp messages.

Keep Confirmation Records

After successful linking, save the confirmation SMS, email, or receipt. These serve as proof of compliance in case your connection is later flagged for deactivation. You may also take a screenshot of the verification status on your service provider’s app or website.

Link All Your Connections Simultaneously

If you have multiple mobile numbers under your name, complete the linking process for all of them at once. Delaying the process for any connection may result in partial deactivation, service disruption, or penalties.

Update Mobile Number in Aadhaar if Changed

If you have recently changed your mobile number, ensure it is updated in your Aadhaar profile before attempting to link it with a new SIM. Otherwise, you may not receive the OTP required for verification.

To update your mobile number with UIDAI, visit the official portal and select “Update Mobile Number.” You will need to authenticate using your existing registered mobile or visit a center for biometric confirmation.

Monitor for Deactivation Alerts

Service providers periodically send reminders to users whose Aadhaar linkage is incomplete. If you receive such a message, act immediately. Failure to comply within the stipulated timeframe may result in suspension of outgoing calls and SMS services, followed by complete deactivation.

Use e-Aadhaar When Physical Card Is Unavailable

If you have misplaced your physical Aadhaar card, you can use the e-Aadhaar downloaded from the UIDAI website. It is a legally valid document for all KYC purposes, including mobile linking. Ensure you print a clear copy or have it accessible on your smartphone during in-person verification.

Do Not Share Biometric Data

Biometric authentication is secure only when performed in the presence of authorized personnel using certified devices. Never allow anyone to scan your fingerprints or iris outside an official center. Unauthorized biometric capture is a serious privacy violation and can lead to identity theft.

Regularly Check Linkage Status

Even after successful linking, periodically check the status of your mobile-Aadhaar linkage. Telecom operators may occasionally reset records due to system upgrades or compliance audits. You can check status via your provider’s app, website, or by dialing *145*1

.

Real Examples

Example 1: Ramesh, a Rural Resident in Odisha

Ramesh, a 52-year-old farmer from a village in Odisha, had recently purchased a new prepaid SIM card for communication with local markets. When he tried to make an outgoing call after a week, he received a message: “Your connection is pending Aadhaar verification.”

Ramesh did not own a smartphone and had no internet access. He visited the nearest Common Service Center, which was 7 km away. He carried his Aadhaar card and the new SIM. The CSC operator used a biometric device to verify his identity. Within 5 minutes, Ramesh received a confirmation SMS: “Your Aadhaar has been linked successfully.” He was able to resume calls immediately.

Example 2: Priya, a College Student in Bengaluru

Priya, a 20-year-old student, had two mobile numbers — one personal and one provided by her college for official communication. She received separate SMS alerts from Airtel and Jio requesting Aadhaar linkage.

Priya used the Airtel app to link her personal number using OTP verification. For her college number, she discovered that her Aadhaar was registered with an old mobile number she had discontinued. She updated her mobile number on the UIDAI portal first, then returned to the Airtel app and completed the linking process. Both connections were verified within 48 hours.

Example 3: Mr. and Mrs. Kapoor, Managing Family Connections

The Kapoors, a retired couple in Pune, had three mobile numbers under their names: one each for themselves and one for their son who lived abroad. They were unaware that each connection needed individual linking.

They visited their nearest Vi store with all three SIMs and their Aadhaar cards. The executive linked all three numbers in one visit. The couple was surprised to learn their son’s number was flagged because it was registered under his old college address. The staff helped them update the address on the telecom portal using their son’s consent letter and scanned copy of his Aadhaar.

Example 4: Anjali, a Senior Citizen with Accessibility Challenges

Anjali, 78, had difficulty reading small text on her phone and often misplaces her Aadhaar card. She received a deactivation notice and was anxious about losing her connection.

Her granddaughter downloaded her e-Aadhaar from UIDAI’s website and printed it in large font. They then used the USSD method (*145*1

) to initiate linking. Since Anjali’s mobile number was not registered with UIDAI, she received an OTP on her daughter’s phone (which was previously linked). After confirming the OTP, the system successfully linked her number.

They also enrolled Anjali in the mAadhaar app, which now stores her digital Aadhaar and allows voice-based navigation for future use.

Example 5: A Business Owner with Multiple SIMs

Sanjay runs a small retail business and uses four different SIM cards for customer communication, inventory management, and banking alerts. He received multiple alerts about Aadhaar linkage.

He used the Jio app to link two numbers, the Airtel portal for the third, and visited a CSC for the fourth, which was linked to an older network. He kept a spreadsheet documenting each SIM’s status, date of linkage, and confirmation code. When a new employee joined, he used the same process to link their number, ensuring full compliance across his operations.

FAQs

Can I link Aadhaar with a mobile number not registered in my name?

No. Aadhaar linking is strictly tied to the individual whose name appears on the Aadhaar card. You cannot link your Aadhaar to a mobile number registered under someone else’s name, even if you use the SIM. Each connection must be in the name of the Aadhaar holder.

What if my Aadhaar and mobile number are registered under different names?
