FASTag Recharge Online: How to Recharge and Check Your Balance

A FASTag is a sticker on your windscreen with a chip that toll plazas read as you drive through. The toll is deducted from a balance linked to the tag, held by the bank that issued it. Keep that balance topped up and you never stop at a toll booth. Let it run low and the tag can be put on a low-balance exception list, and the next plaza may turn you to the cash lane.

This guide covers recharging and checking that balance, using NPCI's guidance for the National Electronic Toll Collection (NETC) system that FASTag runs on.

Three things are worth knowing before you recharge:

You can recharge online through several routes. All of them credit the same balance with your issuer.

Every FASTag can be recharged through a UPI ID built from your vehicle number. NPCI's FAQ gives the format as netc.<vehicle registration number>@<issuer bank's handle>. For a car registered MH04BB1234 with a tag issued by a given bank, it would be netc.MH04BB1234 followed by that bank's UPI handle.

In a bank or UPI app that offers bill payments, choose FASTag, select your issuer bank, enter your vehicle registration number and fetch the account. Check the vehicle number and name, then pay. You get a Bharat Connect (BBPS) reference, which is the one to quote if the recharge doesn't arrive. Our explainer on BBPS and Bharat Connect covers how those references work.

If you drive through tolls often, an automatic top-up saves you from ever running low. Issuers that offer it typically let you set a threshold and a top-up amount, funded from your bank account. When the top-up is set up as a UPI AutoPay mandate, NPCI's rules exempt FASTag auto-replenishment from the 24-hour pre-debit notice that other recurring UPI debits need, because the top-ups are small and driven by your own usage. Our guide to UPI AutoPay explains how mandates work.

There's no single national balance-check page; your balance lives with your issuer. These are the reliable ways to see it:

Enough for your next trip, with a margin. Low balance isn't just an inconvenience: a tag below its issuer's threshold goes on the NETC low-balance exception list. NPCI's FAQ says a customer with too little balance is allowed through the first toll plaza of a journey, but from the next one the tag shows as low balance, so you'd need to recharge or pay in cash.

Since 1 July 2026, NPCI's rules decline a toll transaction if the tag has been in low balance, blacklist or hotlist status for more than 10 minutes before the reader reads it and stays that way for 10 minutes after. In practice, recharge before you set off, not at the plaza.

If you've bought the FASTag annual pass for National Highway and National Expressway plazas, your wallet balance still matters: NPCI's FAQs note that the pass fee can't be paid from the FASTag wallet, and that the balance is still used for State Highway tolls, parking and other plazas outside the pass. Our guide to the FASTag annual pass explains what it covers.

Until now, changing the bank behind your FASTag meant buying a new tag. NPCI's OneTag (tag portability) circular of September 2026 changes that: you'll be able to move your existing FASTag to another issuer without replacing the sticker, keeping the same tag ID and vehicle registration number. Member banks must go live with it by 15 October 2026.

NPCI's FAQ is direct: if you recharged and the money was debited from your account but not credited to your FASTag, call your issuer bank's call centre and ask for a reversal. Our guide to FASTag recharge failed or pending covers that case, double deductions at tolls, and how to complain.
