The introduction of FASTag has transformed how motorists pay tolls across India. No more long queues or fumbling for change with a simple electronic tag on your windscreen, toll payments are now seamless and cashless. However, like any digital payment system, users sometimes face issues, especially when it comes to FASTag recharge and FASTag balance check after reloading their accounts.
If you've ever recharged your FASTag but didn't see the updated balance immediately, or encountered errors while checking your balance, you're not alone. These problems are common but can be easily fixed with the right steps.
In this post, we'll explore the most frequent issues users face with FASTag recharge and balance checks and how to resolve them quickly to ensure a smooth travel experience.

Understanding How FASTag Works
Before diving into the issues, it's important to understand how FASTag functions.
A FASTag is a prepaid RFID (Radio Frequency Identification) tag issued by authorised banks and financial institutions. It is linked to your bank account or a prepaid wallet. When your vehicle passes through a toll plaza, sensors automatically scan your FASTag and deduct the toll amount electronically.
To ensure uninterrupted travel, it's crucial to recharge your FASTag before it runs low on balance. Regular FASTag balance checks help you monitor your account and avoid penalties or double toll charges.
Leading banks such as ICICI Bank offer multiple recharge options through Net Banking, UPI, iMobile app and the customer portal, ensuring convenience and control for every vehicle owner.
Common Issues After FASTag Recharge and Their Fixes
Let's go through the most frequently reported issues users encounter after recharging their FASTag and the practical ways to resolve them.
1. Recharge Amount Not Reflecting in FASTag Balance
The Issue: You've completed the FASTag recharge, but your account balance hasn't updated yet, leaving you unsure whether the payment went through.
Possible Reasons:
- Transaction delay from the payment gateway or bank.
- Network congestion during peak hours.
- Recharge made using incorrect details, such as a wrong vehicle number or customer ID.
Fix:
- Wait for 30-60 minutes, sometimes, the balance takes a short while to update.
- Log in to your FASTag account via your issuing bank's portal (for example, the ICICI Bank FASTag Customer Portal) and check your transaction history.
- If the recharge still doesn't reflect, contact customer support with your transaction reference number.
- In case of incorrect details entered, raise a reversal request with your bank.
When recharging via UPI, always verify your vehicle number (e.g., netc.@icici) to avoid crediting funds to the wrong tag.
2. Incorrect FASTag Balance Display
The Issue: After a FASTag recharge, the displayed balance seems lower than expected, even though the recharge amount was deducted from your account.
Possible Reasons:
- Toll transactions are deducted during your recharge window.
- Auto-recharge or standing instructions are triggered at the same time.
- Delayed transaction updates from toll plazas.
Fix:
- Check your detailed statement through your FASTag customer portal or iMobile app to identify recent toll deductions.
- If the discrepancy remains unresolved after 24 hours, raise a ticket through customer care or email with transaction proofs.
- Enable SMS alerts or notifications to stay updated on every debit.
3. Double Deduction at Toll Plaza
The Issue: Sometimes, due to system lag or network interruption, users see double deductions for the same toll transaction.
Possible Reasons:
- Tag scanned multiple times at the plaza.
- Connectivity errors between the toll operator and your issuing bank.
Fix:
- Note down the toll plaza name, transaction time and receipt ID (if available).
- Raise a dispute through your bank's FASTag customer care portal.
- Refunds are generally processed within 7 working days after verification.
Keep your toll receipts until the transaction reflects correctly in your FASTag account.
4. FASTag Balance Showing as Negative After Recharge
The Issue: After completing your FASTag recharge, your account still shows a negative balance or insufficient funds.
Possible Reasons:
- Pending toll deduction processed immediately after recharge.
- Recharge credited to the wallet but not transferred to the tag.
Fix:
- Log in to your bank's FASTag portal and check if your recharge is in the "CUG Wallet" or "Tag Account."
- Manually transfer funds from the wallet to the tag using the "CUG Balance Transfer" option.
- For recurring issues, set up automatic transfers or Standing Instructions (SI) via Net Banking or the mobile banking apps like the iMobile app to avoid future shortfalls.
Example: In ICICI Bank FASTag, you can configure Standing Instructions so that when your balance drops below ₹100, it automatically tops up by ₹1,000, ensuring uninterrupted toll payments.
5. FASTag Status Inactive After Recharge
The Issue: Your tag status appears as inactive or blacklisted, even though you've recharged it recently.
Possible Reasons:
- Recharge processed after a negative balance was incurred.
- Delay in activation from the issuing bank.
- Pending KYC or document updates.
Fix:
- Check your tag status using your FASTag balance check page or mobile app.
- Contact customer care and share the recharge transaction ID.
- Ensure your KYC details are updated, incomplete verification can lead to auto-suspension of the tag.
- Once verified, your tag should be reactivated within 24 hours.
6. FASTag Balance Not Updating After UPI Recharge
The Issue: You've recharged through UPI but can't see the updated balance in your tag account.
Possible Reasons:
- Incorrect UPI ID format.
- Delay in UPI settlement between your bank and the issuing bank.
Fix:
- Use the correct UPI ID format: netc.@icici (for example, netc.DL01AB1234@icici).
- Verify whether your bank app shows a "Payment Successful" status.
- Wait for at least 30 minutes; if not credited, contact support with the UPI Reference Number (UTR).
For hassle-free transactions, perform recharges during non-peak hours or via your bank's Net Banking portal.
7. Unable to Check FASTag Balance
The Issue: Users sometimes face errors while performing a FASTag balance check, such as failed logins, blank dashboards, or delayed updates.
Possible Reasons:
- Server maintenance at the bank's end.
- Outdated app version or browser cache issues.
Fix:
- Try checking your balance using alternate channels like SMS alerts, the iMobile app, or the customer portal.
- Clear your browser cache or update your app.
- You can also check your balance by giving a missed call to the official FASTag helpline number registered with your issuing bank.
For instance, ICICI Bank FASTag users can perform balance checks via the iMobile app, Net Banking, or by logging in to the ICICI Bank FASTag customer portal.
Tips to Avoid FASTag Recharge Issues in the Future
To ensure uninterrupted travel and smooth transactions, follow these preventive measures:
1. Set Auto-Recharge or Standing Instructions: Link your FASTag to your Savings Account or debit card for automatic top-ups when the balance dips below a threshold.
2. Recharge in Advance: Always maintain a sufficient balance, especially before long trips.
3. Verify Details Before Payment: Ensure your vehicle number, customer ID and bank name are correctly entered during FASTag recharge.
4. Use Official Channels Only: Avoid third-party websites or apps. Recharge through your bank's portal, authorised app, or UPI handle.
5. Keep KYC Updated: Incomplete documentation can lead to tag suspension or failed recharges.
6. Regularly Perform FASTag Balance Check: Make it a habit to monitor your account before every trip.
