New Delhi — Let’s be honest: without an updated mobile number linked to your Aadhaar card, even the smallest tasks can turn into a headache. From opening a bank account to verifying your identity online, that one-time password (OTP) sent to your number is crucial. But what if you’ve changed your number and forgot to update it in Aadhaar? No worries—we’ve got you covered.
Here’s a super simple guide to help you get your mobile number updated in your Aadhaar card without any fuss.
Why It’s a Big Deal to Link Your Mobile Number with Aadhaar
These days, your Aadhaar is like your all-access pass. Whether you’re applying for government schemes, filing taxes, or logging into your bank account, it plays a key role. And here’s the kicker—most of these services send an OTP to your Aadhaar-registered mobile number for verification.
If your number isn’t linked or is outdated, you won’t get that OTP. That means… no access. Which leads to a lot of frustration.
So, to avoid last-minute chaos, it’s important to make sure your active mobile number is linked and up to date in the Aadhaar database.
