How to Block a Merchant From Charging Your Card

To block a merchant from charging your card, cancel with the merchant in writing, then tell your bank to stop the payments. For a debit card or ACH pull, you have the right under the Electronic Fund Transfer Act to place a stop payment or revoke the merchant’s authorization. For a credit card, you file a billing error dispute under the Fair Credit Billing Act. If charges keep coming, replacing the card is the last step. The order matters, because blocking a payment while a contract is still active can send you to collections.

Cancel With the Merchant First

Contact the company and tell them you are revoking permission for automatic payments. Most merchants offer a cancellation path through their website, app, phone line, or email. You can end automatic billing without ending the underlying service if you’d rather switch to paying invoices manually.¹

Get proof. A confirmation number, a dated email, or a screenshot of a cancellation page all work. If the only option is a phone call, write down the date, time, and representative’s name. For high-value contracts or merchants who have ignored earlier requests, send a cancellation letter by certified mail with return receipt requested. That documentation is what your bank, card issuer, or a collector will ask for later.

Online subscriptions carry extra leverage. The Restore Online Shoppers’ Confidence Act makes it illegal to charge you through an online negative option feature, such as a free trial that rolls into a paid subscription, unless the seller provides simple mechanisms to stop the recurring charges.² The FTC’s Negative Option Rule adds that sellers must promptly terminate any subscriber who submits a written cancellation request.³ A merchant hiding the cancel button is not just annoying; it is a violation you can complain to the FTC about.

Stop a Debit Card or ACH Charge Through Your Bank

When the money comes out of your bank account by debit card or ACH, the Electronic Fund Transfer Act lets you stop the payments by telling your bank. You do not need the merchant to agree.⁴

Stop Payment vs. Revoking Authorization

Banks handle two different requests, and the wording matters. A stop payment order blocks a specific upcoming transfer, and if the merchant resubmits the same charge the bank must keep honoring the stop order until you say otherwise. A revocation of authorization goes further, telling the bank the merchant no longer has permission to debit your account at all, so all future payments from that merchant get blocked.⁴ Say which one you want.

What Your Bank Will Ask For

Pull your latest statement and have these ready:

The merchant name exactly as it appears on the statement, which is often different from the brand name you know.
The precise recurring charge amount.
The date the most recent charge posted.

Most banks accept the request through online banking or the mobile app, and you can also call or visit a branch.

Timing, Written Follow-Up, and Fees

Notify your bank at least three business days before the next scheduled transfer.⁵ You can give the notice orally, but the bank is allowed to require written confirmation within 14 days. If it does and you don’t send anything, an oral stop payment expires after those 14 days.⁴ Ask on the call whether written follow-up is required, and send it right away if so.

Expect a fee. Stop payment orders commonly run $25 to $35, though some accounts waive or discount them. A full revocation of authorization under the EFTA should permanently cut the merchant off, but bank policies on duration vary, so confirm how long the block lasts and whether it needs renewing.

Dispute a Credit Card Charge

Credit cards use a different process. Instead of a stop payment, you file a billing error dispute under the Fair Credit Billing Act and Regulation Z. This can reverse charges that have already posted, which a stop payment cannot do.

You have 60 days after the issuer sends the statement containing the disputed charge to submit a written billing error notice.⁶ Send it to the address the issuer designates for billing disputes, not the general payment address, and include your name, account number, and a description of the charge with its date and amount. A recurring subscription charge that keeps hitting your card after you canceled fits the framework, because the merchant no longer has your authorization.

The issuer must acknowledge the dispute in writing within 30 days and resolve it within two complete billing cycles, capped at 90 days.⁶ While the investigation runs, the issuer cannot try to collect the disputed amount or report it as delinquent. If it finds a billing error, it has to correct the charge and any related finance charges.

Replace the Card if Charges Keep Coming

If a merchant refuses to honor your cancellation, asking for a new card number is the most direct way to cut off access. Your bank deactivates the old card and issues a replacement, and charges submitted to the old number stop going through.⁷

A new number is not always the end of it. Visa and Mastercard both run Automatic Billing Updater services that push your new card details out to merchants with a recurring billing relationship on the old card. The point is to keep legitimate subscriptions from lapsing, but a merchant you are trying to block can also pick up your new number within a billing cycle or two.⁸ When you request the replacement, ask the bank to opt your account out of the updater service, or at minimum to flag the specific merchant. Watch the new statements closely for the next two to three months.

Digital wallets are the other quiet channel. Tokens stored in Apple Pay, Google Pay, or a similar wallet can migrate automatically when your card is reissued, so a merchant with a stored token may keep charging without you re-adding anything. After a card replacement, open your wallet settings and remove tokens tied to any merchant you want blocked.

What You Owe if an Unauthorized Charge Slips Through

Federal law caps your liability differently depending on the card. On a debit card, Regulation E ties your exposure to how fast you report it:

Within 2 business days: capped at $50, or the amount of unauthorized transfers before you notified the bank, whichever is less.
After 2 business days but within 60 days of the statement: up to $500.
After 60 days: potentially the full amount of any unauthorized transfers that occur after the 60-day window closes, with no cap.⁹

The jump after 60 days is the reason to review debit statements as soon as they arrive.

Credit cards are gentler. Federal law caps liability for unauthorized credit card charges at $50, and only if certain conditions are met, including that the unauthorized use occurred before you notified the issuer. Once you report the card compromised, any charges after that point are on the issuer.¹⁰¹¹¹² Those network policies do not cover commercial cards or unregistered prepaid cards such as gift cards.

Why Canceling Before Blocking Matters

A stop payment or a card replacement keeps money from leaving your account, but neither one cancels the contract behind the charges. If you block payments while a valid service agreement is still active, the merchant can treat the unpaid balance as a debt you owe.

That balance can be handed to a collection agency, and unpaid amounts sent to collections can appear on your credit report and drag your score down, even when the original subscription was never reported. Contacting the merchant to cancel first removes the argument that you still owe for services under an active contract.

If you have already canceled and the merchant keeps charging anyway, blocking the payment carries far less risk. Your documentation shows you ended the agreement, which is what protects you if the merchant tries to collect or fights a chargeback. For a subscription you signed up for online, a merchant who did not give you a simple way to cancel may be violating federal law in the first place, which is added ammunition against any collection attempt.²
