What MCC 4784 covers
Merchant Category Code 4784 is the ISO 18245 identifier used by the card networks for tolls & bridge fees. Acquirers, issuers and regulators use this code to set interchange, scheme fees, fraud rules and reporting categories for every transaction your business processes.
Highway toll authorities and bridge crossings. Choosing the right MCC is critical: an incorrect code can lead to higher interchange, surcharges, or, in regulated categories, declined transactions and account holds.
This MCC is used by entities managing toll highways, bridges, and tunnels. Transactions are typically low value, high frequency, and often occur in rapid succession, sometimes within minutes.
Customers are often in transit, making immediate dispute resolution challenging.
Chargebacks are relatively low by volume but can arise from customers disputing incorrect tolls, duplicate charges, or charges for vehicles they no longer own or operate. Contactless payment methods, including NFC and automatic licence plate recognition (ALPR) systems linked to payment cards, are prevalent.
Scheme rules often classify these transactions as card-present, even when automated, due to the physical presence of the vehicle. Visa's Quick Payment Service (QPS) and Mastercard's M/Chip Fast programmes facilitate expedited processing for low-value, high-speed environments.
Cardflo's ability to support rapid, tokenised transactions with minimal friction aligns well with the need for efficient throughput at toll plazas.
Merchants in tolls and bridge fees must optimise for speed and convenience, favouring tokenised transactions and ANPR integrations. Transaction values are low but frequent, so acceptance must be robust for high volume.
Configure multi-acquirer routing to ensure high authorisation rates even during network outages. Given the low dispute rates, reserves are rarely an issue, but ensure clear signage and online information to pre-empt basic customer service queries.
Focus on rapid processing of numerous low-value transactions, streamlining reconciliation for audit purposes.
Acquirer and acquirer assessment stance.
Low-risk standard board. Transaction characteristics are well-defined, and the risk of financial loss due to fraud is typically low.
Reserves are not usually required.
Dispute and chargeback profile.
The most likely chargeback reason codes are 13.1 / 4853 (services not as described) for incorrect toll charges, and 10.4 / 4834 (fraudulent transaction) for transactions on unrecognised plates or cards.
Disputes often arise from customers forgetting they passed a toll point or from errors in ANPR systems. To defeat these, provide clear evidence of vehicle passage, time stamps, ANPR records or transponder reads, and geo-location data, linking it to the specific payment method used.
High quality data capture is key.

Common questions
How do automated toll systems using ALPR or RFID tags handle card updates, particularly for recurring payments?
Automated toll systems that link a payment card to a vehicle or account typically utilise card updater services (e. g. , Visa Account Updater, Mastercard Automatic Billing Updater) to automatically receive updated card numbers or expiry dates from issuers.
This minimises declines due to expired cards and ensures continuous service without requiring manual intervention from the cardholder, crucial for high-frequency users.
Are toll transactions eligible for 3D Secure authentication?
While technically possible, 3D Secure is generally not applied to most toll transactions. These are often processed as low-value, card-present (or functionally card-present via tokenisation) transactions, falling under exemptions for low-value payments or merchant-initiated transactions (MITs) where a prior customer agreement exists.
Applying 3DS would introduce friction incompatible with the expected speed of service at toll points.
What is the typical dispute window for a toll charge?
The dispute window for toll charges generally follows standard scheme rules; for instance, Mastercard typically allows cardholders 120 calendar days from the transaction processing date to dispute a charge, and Visa allows up to 120 or 180 days depending on the dispute reason.
However, prompt investigation by the cardholder upon seeing an unfamiliar charge is always recommended.
How can toll operators minimise chargebacks from customers claiming they were incorrectly charged for a different vehicle?
To minimise chargebacks related to incorrect vehicle identification, toll operators should ensure their ANPR systems are highly accurate and regularly maintained. Implement a clear, easily accessible online portal where customers can view their toll history, vehicle images, and dispute charges directly before resorting to chargebacks.
Provide high-resolution timestamped images of the vehicle and licence plate taken at the point of toll, alongside the associated payment ID. For manual interventions, ensure robust audit trails.
Offering a simple self-service correction mechanism for minor errors can significantly reduce formal disputes and improve customer satisfaction, protecting revenue from unnecessary reversals.
What payment acceptance strategies are most effective for peak traffic times at toll booths with high transaction volumes?
During peak traffic, efficiency is paramount. Implement contactless payment methods, including NFC, smartphone wallets, and integrated ANPR systems linked to pre-registered payment cards, to minimise physical interaction and speed up throughput.
Ensure your payment gateway and acquirer network can handle high transaction concurrency. Utilise multi-acquirer routing to diversify processing channels and prevent single points of failure, which could lead to declines during peak loads.
Tokenisation of card details for repeat customers also accelerates the process, as full card data transmission is avoided, reducing latency and bolstering security while maintaining PCI DSS compliance.
