Your Aadhaar card is the cornerstone of your identity in the digital India ecosystem, and the mobile number linked to it serves as the primary channel for receiving OTPs, notifications, and critical updates. When you change your phone number, whether due to a new SIM card or a port to a new provider, it is imperative to update this record with the Unique Identification Authority of India (UIDAI) to ensure uninterrupted access to government services and to safeguard your personal data against unauthorized access.
Why Updating Your Mobile Number is Crucial
The linkage between your Aadhaar and mobile number is the backbone of the verification process for everything from opening a new bank account to filing your income tax returns. An outdated mobile number creates a digital dead end, preventing you from receiving the One-Time Passwords required for authentication. This not only causes friction in daily transactions but also poses a significant security risk, as the old number might be reassigned to another person who could potentially intercept your sensitive information.
Pre-requisites Before You Begin
Before initiating the update process, ensure you have the necessary infrastructure in place. You will need the new active SIM card inserted into the phone you intend to use for the update, as the OTP verification is sent to this specific number. Additionally, make sure you have your original Aadhaar card, or at least the 12-digit Aadhaar number memorized, and a valid form of identification such as a passport or driver’s license to cross-verify your identity during the update process.
Method 1: Online Update via the UIDAI Website
The most direct approach to changing your mobile number is through the official portal of the UIDAI. This method requires you to generate an OTP based on your existing registered number to authenticate the change request. While this process is entirely digital, it demands a high level of accuracy in entering the details to match the biometric data stored in the UIDAI database.
Step
Action
1
Visit the official UIDAI website (uidai.gov.in) and navigate to the "Update Your Aadhaar" section.
2
Enter your Aadhaar number and the captcha code, then submit to generate an OTP.
3
Enter the OTP sent to your current mobile number to verify your identity.
4
Input the new 10-digit mobile number and submit the update request.
Method 2: Visiting an Aadhaar Enrollment Center
If you face technical difficulties or are unable to access the online portal, visiting an Aadhaar Enrollment Center remains a reliable fallback. Here, an executive will assist you in filling out the correction form. The advantage of this method is the immediate resolution of issues related to biometric mismatches or documentation errors that might block online verification.
When you visit the center, you must carry the original documents and the Aadhaar card. The process usually involves submitting Form 6, which is specifically designated for updating demographic information, including your mobile number. The executive will scan your documents, capture your photograph if necessary, and update the database with your new contact details.
