How To Change Fastag Mobile Number

FASTag has truly revolutionized the way toll collection systems work in the country. If you have signed up for FASTag, and have it attached to the front windshield of the car/vehicle then you are good to go. You won’t need to pay the toll in cash, and it’ll certainly save a lot of time too. But sometimes it happens when your FASTag registered mobile number is not with you or you have recently changed your primary number, in that case, it is important for you to change or update the number in FASTag as well. That way you’ll receive all the important notifications and messages on your new mobile number. And guess what? Today’s post is all about how to change your FASTag mobile number, so if you are here just for that, then stick to us a little longer to find that out.

What exactly is FASTag?

FASTag is like a magic sticker you slap on your car’s windshield. What does it do? Well, it’s got this cool tech called RFID which is short for Radio Frequency Identification. Think of it as a high-tech debit card for your car. When you roll up to a toll booth, no need to dig around for coins or wait in line like it’s the 90s. This nifty tag talks to the toll booth and says, “Hey, go ahead and take the toll money from my account!” Just like that, the cash gets zapped from a prepaid account or your regular savings account. Super easy, right? And guess what? You get to cruise on through without stopping!


And why is a Mobile Number Important for FASTag?

Okay, so you may be wondering, “Why do I need my phone number for this?” Great question! Imagine you just drove through a toll booth. Your FASTag does its thing, and boom, money’s gone from your account. But how do you know for sure? Well, that’s where your phone buzzes and tells you, “Hey, you just paid this much at this toll booth!” It’s a simple text alert.

So, having your current mobile number is kinda like having a receipt in your pocket. You’ll know exactly how much you got charged and where. And if some funny business happens, like a charge you didn’t expect, your phone will tell you straight away. So if you’ve got an old number on there, or worse, someone else’s, you’re gonna miss out on all this useful info.
