Account Updater
What Is Account Updater? Definition and How It Works
Definition
Account Updater is a card network service that automatically provides merchants and payment providers with updated card details when a stored card has been reissued, replaced, expired, or closed. By keeping stored payment credentials current without requiring the cardholder to re-enter their details, Account Updater reduces failed recurring payments, prevents involuntary subscription churn, and maintains uninterrupted billing for merchants storing card-on-file credentials.
How it works
Account Updater is offered by Visa (as Visa Account Updater, VAU) and Mastercard (as Mastercard Automatic Billing Updater, ABU). Merchants or their payment providers submit a batch of stored card tokens or PANs to the service. The card networks query their issuer databases for updated card information and return the results: a new card number and expiry date if the card has been reissued, a new expiry date if only the card has been renewed, a closed account indicator if the account has been cancelled, or a no-change response if the stored credentials remain valid.
Updates are applied to the merchant's stored token database before the next billing cycle. When a recurring charge is initiated against an updated credential, the merchant submits the new token or card details and the authorisation succeeds where it would otherwise have failed on the expired or replaced card number.
The service operates in batch mode (merchants submit files and receive updates at scheduled intervals) or in real-time mode (updates are requested and returned at the point of a failed authorisation, enabling immediate retry with updated credentials). Real-time Account Updater is more effective at recovering failed payments because it eliminates the gap between card replacement and credential update.
Network tokenisation, where the stored credential is a network-issued token rather than a raw PAN, partially automates this process: network tokens are maintained by the card network and updated automatically when the underlying card changes, without requiring the merchant to submit batch update requests. Merchants using network tokenisation for recurring billing experience significantly fewer card expiry-related failures.
Why it matters
Card expiry and replacement is a primary driver of involuntary churn for subscription businesses. In a typical card portfolio, roughly 20% to 25% of cards are reissued annually due to expiry, replacement after fraud, damage, or voluntary upgrades. Without Account Updater, every reissued card that is stored for recurring billing generates a failed payment at the next billing cycle, triggering a missed payment notification and involuntary cancellation if the customer does not update their details.
The revenue impact of involuntary churn from stale card credentials is measurable and material. A subscription business with 100,000 active subscribers, a 2% monthly failed payment rate from expired cards, and a 30% recovery rate from dunning campaigns is losing approximately 1.4% of subscribers per month to involuntary churn that Account Updater could prevent. At an average subscription value of $50 per month, that is $70,000 per month in recoverable recurring revenue.
Account Updater also reduces the operational overhead of failed payment management. Every failed recurring payment that is not recovered automatically requires dunning communication, customer service interaction, or manual re-billing. Automating credential updates eliminates this overhead for the majority of card replacement scenarios.

Frequently asked questions
How often should merchants run Account Updater?
Best practice is to run Account Updater on stored credentials 7 to 14 days before the next scheduled billing date. This gives sufficient time for updates to be applied before the charge is initiated, without running updates so far in advance that further card changes occur between the update and the billing date. High-frequency billers (weekly billing) should run updates more frequently than monthly billers.
Does Account Updater work for all card types?
Account Updater is available for Visa and Mastercard credit and debit cards issued by participating issuers. Not all issuers participate, and participation rates vary by market. In the US, participation among major issuers is high. In some international markets, participation is lower, meaning Account Updater does not resolve all credential staleness issues. Network tokenisation has broader automatic update coverage because it operates at the network level rather than depending on individual issuer participation.
What is the difference between Account Updater and network tokenisation for recurring payments?
Account Updater is a batch or real-time service that queries issuers for updated card credentials and returns new PANs or expiry dates for the merchant to store. Network tokenisation replaces the stored PAN with a network-issued token that the card network maintains automatically: when the underlying card changes, the network updates the token mapping without requiring the merchant to submit an update request. Network tokenisation is more automated and provides continuous maintenance, while Account Updater is a periodic reconciliation process. For optimal recurring payment performance, using both in combination is common.
