To block a company from charging your card, do two things: tell the merchant in writing that you are revoking authorization for future payments, and place a stop payment order with your bank. Federal law gives you the right to stop preauthorized charges at any time, and your bank must honor a properly submitted request. Credit cards and debit cards follow different rules once a charge slips through, and blocking payment does not, on its own, cancel any contract you signed.
Revoke Authorization With the Merchant
Start with the company. Send a written cancellation by email, support ticket, or letter so you have a dated record of when and how you told them to stop. Many subscription services publish a cancellation procedure in their terms; following it creates a clean paper trail if a later charge needs to be disputed.
This step does two things at once. It puts the merchant on notice that any further charge is unauthorized, which strengthens a future dispute, and it answers the question some banks ask before processing a stop payment: did you already contact the company? Keep the cancellation message and any confirmation reply.
Place a Stop Payment Order With Your Bank
You have a separate right, independent of the merchant, to stop recurring charges by telling your bank. Under the Electronic Fund Transfer Act, you can stop a preauthorized electronic fund transfer by notifying your financial institution, verbally or in writing, at least three business days before the next scheduled charge.1Office of the Law Revision Counsel. 15 USC 1693e Preauthorized Transfers You do not need the merchant’s permission. The right belongs to you as the account holder.
How to Submit the Order
Call your bank’s customer service line, go into a branch, or use the bank’s online portal or mobile app. Many banks now include a stop payment feature inside card settings or the transaction history.
A verbal instruction is enough to trigger the block immediately, but the bank may require written confirmation within 14 days. If you don’t provide that written follow-up when it’s required, the verbal order stops being binding after 14 days and future charges can post again.2Consumer Financial Protection Bureau. Regulation E 1005.10 Preauthorized Transfers
Once the order is in place, the bank must block all future debits from that merchant. If the merchant resubmits the charge, the bank must keep honoring your stop payment until you tell it to resume payments.2Consumer Financial Protection Bureau. Regulation E 1005.10 Preauthorized Transfers
What Your Bank Will Ask For
Pull up your recent statements before you call. The bank will typically want:
- The merchant name as it appears in your transaction history, which sometimes differs from the company’s public name.
- The dollar amount of the recurring charge and how often it posts.
- The specific card or account number the charges hit.
- The date of the most recent charge.
A stop payment description only has to identify the transaction with “reasonable certainty,” so a penny-exact match isn’t strictly required.3Legal Information Institute (LII) / Cornell Law School. UCC 4-403 Customers Right to Stop Payment Burden of Proof of Loss Precise information still helps, because a slightly different amount or a renamed billing descriptor can slip past the block.
Fees
Some banks charge a flat fee for each stop payment order. Others, including some of the largest national banks, do not. Ask before you place the order. If the charge is genuinely unauthorized, the dispute process described below carries no fee and may be the better route.
Why a New Card Number Often Won’t Stop the Charges
Ordering a replacement card is not a reliable way to shut off a recurring charge. Visa, Mastercard, American Express, and Discover all run account updater services that automatically send your new card number and expiration date to merchants who already have your credentials on file. These services exist so legitimate subscriptions keep working when a card is lost, stolen, or expires.
When the merchant participates, your replacement details flow to them automatically and the recurring charges resume on the new card. Visa’s Account Updater lets issuers submit an opt-out code that blocks the sharing of updated information, but the cardholder has to ask the bank for it; it isn’t the default.4Visa Developer. Visa Account Updater (VAU) FAQs Mastercard runs a parallel service called Automatic Billing Updater.5Mastercard Developers. Automatic Billing Updater
If you want to make sure a merchant cannot receive your updated card information, call your bank and ask specifically to be opted out of the card network’s account updater service. Not all banks make this easy; you may need a supervisor or a written request.
If a Charge Already Went Through
When a company charges you after you revoked authorization or after your stop payment was in place, you can dispute the charge and recover the money. The rules differ for credit and debit.
Credit Cards
Credit card disputes fall under the Fair Credit Billing Act. Send written notice to your card issuer within 60 days of the statement date on which the disputed charge appeared. Include your name, account number, the amount, and why you believe the charge is an error, such as a canceled service the merchant billed anyway.6Office of the Law Revision Counsel. 15 USC 1666 Correction of Billing Errors
The issuer must acknowledge your notice within 30 days and resolve the dispute within two billing cycles, capped at 90 days. It cannot try to collect the disputed amount or report it as delinquent while it investigates.6Office of the Law Revision Counsel. 15 USC 1666 Correction of Billing Errors If the charge was an error, the issuer credits your account for the full amount plus any related finance charges. Your maximum liability for an unauthorized credit card charge is $50, no matter when you report it.
Debit Cards
Debit card disputes run under Regulation E. You have 60 days from the date the bank sent the statement to report the error. The bank then has 10 business days to investigate.7Consumer Financial Protection Bureau. Regulation E 1005.11 Procedures for Resolving Errors
The bank can extend the investigation to 45 days, but only if it provisionally credits your account within the original 10 business days and gives you full use of those funds while it finishes looking into the charge.7Consumer Financial Protection Bureau. Regulation E 1005.11 Procedures for Resolving Errors If the bank confirms the error, the provisional credit becomes permanent.
Debit card liability scales with how quickly you report:
- Report within 2 business days: liability capped at $50.
- After 2 business days but within 60 days: liability can rise to $500.
- After 60 days: you can be responsible for the full amount of unauthorized charges that occur after the 60-day window closes.8eCFR. 12 CFR 1005.6 Liability of Consumer for Unauthorized Transfers
That sliding scale is one practical reason credit cards give stronger protection for recurring billing problems. Either way, report fast.
Blocking the Charge Does Not Cancel the Contract
A stop payment stops the transaction. It does not erase a debt or end a contract. If you signed up with a minimum commitment, or you owe a balance on a loan or installment plan, the company can still pursue the money by sending the account to collections, reporting it to credit bureaus, or suing for breach of contract.
Stop payment orders and card blocks fit situations where the merchant is charging without authorization, where you have already properly canceled a service, or where the charge is a clear error. They are not a workaround for a subscription you never canceled or a balance you still owe. If you aren’t sure where you stand under the contract, sort that out with the company before you block the charges, or expect the unpaid amount to be treated as a debt.
