Your Aadhaar Card is more than just an identity document in India—it’s a gateway to countless services, from banking to government schemes. But what happens when your registered mobile number changes? Without an updated number linked to your Aadhaar, you could miss out on OTPs (One-Time Passwords) for verification, leaving you stuck when accessing critical services. Whether you’ve switched SIMs, lost your old number, or simply want a more convenient one, updating your mobile number in Aadhaar is essential. The good news? The Unique Identification Authority of India (UIDAI) offers both online and offline methods to make this process seamless. So, how do you update your new mobile number in your Aadhaar Card? Let’s dive into this detailed guide to explore every step of the online and offline processes.
Why Updating Your Mobile Number in Aadhaar Matters
Before we get into the “how,” let’s talk about the “why.” Your mobile number is the lifeline of your Aadhaar Card. It’s tied to authentication processes for everything—filing taxes, opening a bank account, or even booking a gas cylinder. If your registered number is outdated or inactive, you won’t receive OTPs, rendering your Aadhaar less functional. In a country where digital transactions and e-governance are on the rise, keeping your contact details current is non-negotiable. Plus, with scams and privacy concerns, linking a number you actively use ensures better security. Ready to update? Here’s how you can do it, step by step.
Understanding the Aadhaar Mobile Number Update Process
The UIDAI doesn’t allow direct online updates for your mobile number through its website or the mAadhaar app as a standalone process. Why? Because changing a mobile number requires biometric verification for security reasons. However, you can initiate parts of the process online or opt for a fully offline method. As of March 31, 2025, the system blends convenience with strict authentication, ensuring your Aadhaar remains safe while adapting to your needs. Let’s break down both approaches—online-assisted and offline—so you can choose what works best for you.
Online-Assisted Process to Update Mobile Number in Aadhaar
While you can’t complete the entire mobile number update online, the UIDAI website and mAadhaar app offer tools to get started. This hybrid method involves booking an appointment or preparing documents online before visiting an Aadhaar center. Here’s how it works:
Step 1: Visit the Official UIDAI Website
Head to the UIDAI’s official portal at uidai.gov.in. This is your starting point for all Aadhaar-related services. The site is user-friendly, available in English and regional languages, and packed with resources. Look for the “My Aadhaar” section or “Update Your Aadhaar” tab on the homepage. These sections guide you toward services like updating details.
Step 2: Book an Appointment Online
Since mobile number updates require biometric authentication (fingerprint or iris scan), you’ll need to visit an Aadhaar Enrolment Centre or Aadhaar Seva Kendra. To avoid long queues, use the “Book an Appointment” option on the UIDAI website. Here’s how:
- Click on “Book an Appointment.”
- Select your city or enter your PIN code to find nearby centers.
- Choose “Mobile Number Update” as the service.
- Pick a convenient date and time slot.
- Enter your current registered mobile number (if accessible) to receive a confirmation OTP, or proceed without it if the number is inactive.
You’ll get an appointment slip with a reference number—save it! This step streamlines your visit and ensures you’re not stuck waiting endlessly.
Step 3: Gather Required Documents
Before heading to the center, prepare these essentials:
- Your Aadhaar number or a copy of your Aadhaar Card (physical or e-Aadhaar).
- A valid identity proof (like a PAN card, passport, or voter ID) for verification.
- Your new mobile number (ensure it’s active, as you may need to verify it later).
No separate proof is needed for the mobile number itself—just make sure it’s in your name or one you control.
Step 4: Visit the Aadhaar Centre
On your appointment day, arrive at the designated Aadhaar Seva Kendra or enrolment center. Submit your appointment slip and documents to the operator. They’ll ask for your biometric details—fingerprint or iris scan—to authenticate your identity. Once verified, provide your new mobile number. The operator will update it in the system and give you an acknowledgment slip with a URN (Update Request Number).
Step 5: Track Your Update Status Online
After your visit, use the URN to track the status on the UIDAI website:
- Go to “Check Aadhaar Update Status” under the “My Aadhaar” section.
- Enter your Aadhaar number and URN.
- Submit to see if the update is processed.
Typically, the new number reflects in your Aadhaar within 10-15 days, though it can take up to 30 days in some cases. Once updated, you’ll receive OTPs on your new number for future verifications.
Benefits of the Online-Assisted Method
This approach saves time by letting you plan ahead. Booking an appointment online reduces chaos at crowded centers, especially in metro cities like Delhi, Mumbai, or Bangalore. It’s ideal if you’re tech-savvy and prefer a structured process. However, if visiting a center isn’t convenient, the offline method might suit you better—keep reading!
Offline Process to Update Mobile Number in Aadhaar
Prefer handling things in person or don’t have internet access? The offline process is straightforward and widely accessible across India’s vast network of Aadhaar centers, post offices, and bank branches. Here’s how to update your mobile number without relying on online tools:
Step 1: Locate an Aadhaar Enrolment Centre
Find a nearby Aadhaar Enrolment Centre or Aadhaar Seva Kendra. These are set up in:
- Government offices.
- Designated bank branches (like SBI, ICICI, or HDFC).
- India Post offices.
- Common Service Centres (CSCs) in rural areas.
To locate one, ask locally, check with your bank, or use the UIDAI’s “Locate an Enrolment Centre” tool online (if you have brief internet access). No appointment is mandatory for the offline method, though walk-in waits can vary.
Step 2: Collect Necessary Documents
Just like the online-assisted process, you’ll need:
- Your Aadhaar Card or Aadhaar number.
- An identity proof (voter ID, driving license, etc.).
- Your new mobile number ready to register.
Carry originals and photocopies, as some centers may ask for both.
Step 3: Visit the Centre and Fill the Form
Walk into the enrolment center and request an Aadhaar Correction Form (also called the Aadhaar Data Update Form). This is available free of charge at the counter. Fill it out with:
- Your 12-digit Aadhaar number.
- Your full name (as on Aadhaar).
- The new mobile number you want to link.
Double-check the details—errors can delay the process. If you’re unsure, the center staff can assist you in filling it out correctly.
Step 4: Submit and Authenticate
Hand over the form and your documents to the operator. They’ll:
- Verify your identity using biometric authentication (fingerprint or iris scan).
- Enter your new mobile number into the UIDAI database.
- Provide an acknowledgment slip with a URN.
The biometric step ensures no one else can tamper with your Aadhaar details, making it a secure process.
Step 5: Wait for Confirmation
Unlike the online-assisted method, tracking status offline isn’t as direct. You can visit the center again with your URN or call the UIDAI helpline (1947) to check progress. The update usually takes 10-30 days, after which your new number becomes active for Aadhaar-related services.
Why Choose the Offline Route?
The offline process is a boon for rural residents, senior citizens, or anyone without reliable internet. With thousands of centers nationwide, it’s accessible even in remote areas. Plus, you get face-to-face assistance, which can be reassuring if you’re new to Aadhaar updates.
Additional Tips for a Smooth Update
Whether you go online-assisted or offline, a few pointers can make the experience hassle-free:
- Verify Centre Authenticity: Stick to UIDAI-authorized centers to avoid fraud. Check for official signage or ask for credentials.
- Keep Your Number Active: The new mobile number should be operational, as some services may send test OTPs post-update.
- Check Fees: Updating your mobile number is usually free, but some centers may charge a nominal fee (₹50 or less) for form processing—confirm beforehand.
- Save the URN: Losing your Update Request Number can complicate tracking, so store the slip safely.
Special Cases: What If You’ve Lost Access Completely?
What if your old number is lost, and you can’t receive OTPs to even start the process? Don’t panic. Visit an Aadhaar Seva Kendra directly with your Aadhaar number and identity proof. Explain your situation to the staff—they’ll use biometric authentication to verify you and proceed with the update. This ensures no one gets locked out of their Aadhaar due to a dead number.
How Aadhaar Updates Fit into Daily Life
Updating your mobile number isn’t just about convenience—it’s about staying connected to India’s digital ecosystem. From linking your Aadhaar to PAN for taxes to accessing subsidies under schemes like PMAY or Ayushman Bharat, an active mobile number keeps you in the loop. In 2025, as e-governance grows, this small step can save you big headaches down the road.
Exploring Alternatives: Banks and Post Offices
Beyond Aadhaar centers, many banks and post offices double as enrolment points. For instance, India Post has integrated Aadhaar services in over 13,000 locations, making it a game-changer for rural India. Similarly, banks like Punjab National Bank or Canara Bank offer counters for updates. Call your branch or post office to confirm availability—it could be a quicker stop than a dedicated Kendra.
The Bigger Picture of Aadhaar Updates
The process to update your mobile number reflects UIDAI’s balance of security and accessibility. Biometric checks protect your identity, while widespread centers and partial online tools ensure inclusivity. Whether you’re in a bustling city or a quiet village, there’s a way to keep your Aadhaar current. So, pick your method—online-assisted or offline—and take charge of your Aadhaar today!
