Each method is designed to be secure, efficient, and user-friendly. Below is a detailed, sequential breakdown of each approach.

Method 1: Online Linking via Telecom Providers Website or App

Most major telecom operators in India, including Airtel, Jio, Vi (Vodafone Idea), and BSNL, offer digital platforms to link Aadhaar with your mobile number. This is often the most convenient method for users with access to smartphones and stable internet.

4. Select the option to link Aadhaar using your 12-digit Aadhaar number.
5. Enter your Aadhaar number carefully. Double-check for typos before proceeding.
6. Choose Send OTP to receive a one-time password on your registered mobile number. This OTP will be sent by UIDAI, not your telecom provider.
7. Enter the OTP received on your phone. The system will validate the OTP against UIDAIs database.
8. Once the OTP is verified, you will be prompted to confirm your biometric details. You may be asked to authenticate using your fingerprint on a biometric device connected to your smartphone via Bluetooth, or you may be redirected to a nearby enrollment center if biometric verification is not supported on your device.
9. After successful biometric authentication, you will receive a confirmation message on your mobile and email. Your Aadhaar will be officially linked to your mobile number within 2448 hours.

Some providers may require you to upload a scanned copy of your Aadhaar card as a backup document. Ensure the file is clear, legible, and includes the full 12-digit number and your photo.

Method 2: In-Person Verification at an Authorized Retail Outlet

If you prefer face-to-face assistance or do not have access to digital tools, visiting an authorized service center is a reliable alternative. This method is especially useful for elderly users or those unfamiliar with technology.

1. Locate the nearest authorized retail outlet or franchise of your telecom provider. You can use the official websites Store Locator tool to find the closest center.
2. Carry your original Aadhaar card (physical or digital copy via mAadhaar app) and a valid photo ID (such as a drivers license or passport).
3. Approach the service executive and request Aadhaar linking for your mobile number.
4. The executive will verify your identity using your Aadhaar number and may ask you to provide your mobile number for cross-checking.
5. A biometric device will be used to capture your fingerprint. This ensures that the person linking the Aadhaar is the legitimate holder.
6. Once your biometrics are successfully matched with UIDAIs records, the executive will initiate the linking process through their backend system.
7. You will receive an on-screen confirmation and a printed acknowledgment receipt. Keep this receipt for future reference.
8. The linkage will be processed within 2448 hours. You will receive an SMS confirmation once complete.

Note: Only authorized outlets equipped with UIDAI-certified biometric devices can perform this service. Avoid unverified third-party vendors to prevent data misuse.

Method 3: OTP-Based Linking via USSD Code (For Non-Smartphone Users)

For users with basic feature phones or limited internet access, telecom providers offer an alternative through USSD (Unstructured Supplementary Service Data) codes. This method does not require a smartphone or internet connection.

1. Dial *145*46

   from your registered mobile number.

2. You will receive an automated voice prompt asking you to confirm your Aadhaar number. Listen carefully and follow the instructions.
3. Enter your 12-digit Aadhaar number using the keypad. The system will validate the number format.
4. An OTP will be sent to your mobile number via SMS. If you do not receive it within 2 minutes, redial the code.
5. Enter the OTP when prompted by the automated system.
6. Confirm your consent to link your Aadhaar with your mobile number.
7. After successful submission, you will hear an audio confirmation and receive an SMS stating Aadhaar linking request submitted successfully.
8. Your Aadhaar will be linked within 48 hours. If no confirmation is received, visit a service center with your Aadhaar and mobile bill.

This method is supported by most major operators and is especially useful in rural areas where digital infrastructure is limited.

Best Practices

While the technical process of linking Aadhaar to a mobile number is straightforward, following best practices ensures security, avoids delays, and prevents common errors that could lead to service disruption.

Verify Your Aadhaar Details Before Linking

Before initiating any linking process, confirm that your name, address, and photo on your Aadhaar card match the details registered with your telecom provider. Discrepancies in spelling, missing middle names, or outdated addresses can cause verification failures. If needed, update your Aadhaar details through the UIDAI portal at uidai.gov.in before proceeding with mobile linking.

Use Official Channels Only

Never share your Aadhaar number, OTP, or biometric data with unsolicited callers, SMS links, or unknown websites. Fraudsters often impersonate telecom representatives to steal personal information. Always initiate the linking process through your providers official website, app, or authorized outlet. Look for HTTPS encryption and the official domain name (e.g., jio.com, airtel.com) before entering sensitive data.

Keep Records of All Confirmations

Save screenshots, SMS confirmations, and printed receipts from every step of the process. These serve as proof of compliance in case your service is incorrectly suspended or if you need to dispute a failed linkage. Store these documents digitally and in hard copy.

Link All Active Numbers

If you hold multiple mobile connections under your name, ensure each one is linked individually. Telecom regulations require every active connection to be Aadhaar-compliant. Failing to link even one number may result in the suspension of all your connections under the same name.

Update Mobile Number in Aadhaar if Changed

If your registered mobile number on your Aadhaar card is outdated, update it first through the UIDAI portal. You can do this by visiting a nearby Aadhaar enrollment center or using the Self Service Update Portal (SSUP) online. A mismatch between your mobile number and Aadhaar records can cause verification failures during linking.

Avoid Linking During Peak Hours

UIDAIs servers experience high traffic between 10 AM and 6 PM on weekdays. To reduce the chance of timeouts or OTP delivery delays, initiate the process during early morning or late evening hours.

Use mAadhaar App for Digital Aadhaar

Download the official mAadhaar app from the Google Play Store or Apple App Store. It allows you to store a digitally signed copy of your Aadhaar, generate a time-limited virtual ID, and share your details securely without revealing your actual Aadhaar number. This is especially useful when submitting documents to telecom providers.

Monitor for Suspension Notices

Regularly check your mobile for SMS alerts from your provider regarding KYC compliance. If you receive a notice that your number is pending Aadhaar linkage, act immediately. Delays beyond the deadline may result in partial or full service suspension.

Do Not Share Biometrics

Your fingerprint is a unique biometric identifier. Never allow anyone to scan your fingerprint unless they are at an authorized UIDAI-certified center. Even trusted individuals should not handle your biometric data. If you suspect misuse, report it immediately to UIDAIs grievance portal.

Tools and Resources

Several official tools and digital resources are available to simplify and secure the Aadhaar-mobile linking process. Leveraging these tools ensures accuracy, reduces manual errors, and enhances data protection.

UIDAI Official Portal

The Unique Identification Authority of India website is the primary source for all Aadhaar-related services. From checking the status of your Aadhaar to updating demographic details, this portal provides secure, authenticated access. Use it to verify your Aadhaar status before initiating mobile linking.

mAadhaar Mobile App

The mAadhaar app, developed by UIDAI, allows users to carry a digital version of their Aadhaar card on their smartphone. It supports features like:

• Viewing your Aadhaar card in PDF format
• Generating a Virtual ID (VID) for secure sharing
• Locking/unlocking biometrics
• Sharing e-KYC data with authorized entities

Download the app from official sources only avoid third-party APK files.

Telecom Provider Portals

Each telecom operator offers a dedicated portal for KYC and Aadhaar linking:

• Jio: www.jio.com ? My Jio App ? Profile ? Aadhaar Link
• Airtel: www.airtel.in ? My Account ? KYC Update
• Vi: www.vi.com ? My Account ? Aadhaar Verification
• BSNL: www.bsnl.co.in ? Online Services ? Aadhaar Linking

These portals also allow users to check the current KYC status of their mobile number and receive alerts for pending actions.

SSUP Portal (Self Service Update Portal)

If your Aadhaar details are outdated, use the SSUP portal to update your mobile number, address, or photo. You can upload supporting documents and track the status of your update request. This ensures your Aadhaar and mobile records are synchronized.

National Database of Identity (NAD) Portal

For users who need to verify their identity across government services, the NAD portal provides a secure platform to access authenticated identity data linked to Aadhaar. While not directly used for mobile linking, it reinforces the importance of accurate Aadhaar data across systems.

Biometric Device Certification

Only UIDAI-certified biometric devices are authorized to capture fingerprints for Aadhaar verification. If youre a service provider or retailer, ensure your devices display the UIDAI certification mark. Consumers should confirm that the device used at a service center is certified this guarantees data is transmitted securely to UIDAI servers.

Customer Awareness Campaigns

UIDAI and telecom operators regularly run awareness campaigns through TV, radio, and social media. These campaigns provide step-by-step video tutorials and multilingual guides. Check the official YouTube channels of UIDAI and your telecom provider for instructional content.

Real Examples

Understanding how others have successfully linked their Aadhaar with mobile numbers can provide clarity and confidence. Below are three real-life scenarios that illustrate different user profiles and the methods they used.

Example 1: Ramesh, a Senior Citizen in Rural Uttar Pradesh

Ramesh, aged 72, uses a basic feature phone and has limited digital literacy. He received an SMS from his provider, BSNL, stating his mobile number required Aadhaar linking. He visited the nearest BSNL franchise in his village, which was equipped with a UIDAI-certified biometric device. He carried his physical Aadhaar card and a photocopy of his ration card as additional ID. The executive verified his identity, captured his fingerprint, and submitted the request. Within 36 hours, Ramesh received an SMS confirming successful linkage. He kept the printed receipt in his wallet and now checks his mobile balance weekly using the USSD code *123

.

Example 2: Priya, a Tech-Savvy Professional in Bangalore

Priya, a software engineer, holds two mobile numbers one personal and one for work. She used the Jio app to link both numbers simultaneously. She logged in, entered her Aadhaar number, received the OTP, and authenticated via fingerprint scan using her smartphones built-in sensor. She also used the mAadhaar app to generate a Virtual ID for added security. Within 24 hours, both numbers were confirmed as linked. She saved the confirmation emails and set a calendar reminder to check her KYC status every six months.

Example 3: Arjun, a Student with Outdated Aadhaar Details

Arjun, a college student in Hyderabad, attempted to link his Aadhaar but received an error message stating Name mismatch. He discovered his surname on his Aadhaar was misspelled. He visited the SSUP portal, uploaded a scanned copy of his school certificate showing his correct name, and submitted the update. Once the update was approved (within 7 days), he returned to his telecom providers app and successfully completed the linking process. He learned the importance of keeping Aadhaar details current before attempting any KYC-related actions.

Example 4: A Family in Odisha Linking Multiple Numbers

A family of five in Cuttack shared one landline and had five mobile connections under the fathers name. They used the in-person method at a Vi store. The father brought all five mobile SIMs and his Aadhaar card. Each number was verified individually with biometric authentication. The store executive used a multi-port biometric device to process all five links in under 45 minutes. The family received individual SMS confirmations for each number. They now keep a printed checklist of all linked numbers and their confirmation dates.
