Chargeback Response Time LimitIn Many Cases, You’ll Have a Week (or Less) to Submit Your Response

Chargeback Response Time Limit

In a Nutshell

Merchants typically have between 20 and 45 days to respond to a chargeback, depending on the card network. These deadlines start when the chargeback is filed, not when the merchant receives notification, which can significantly shrink the actual working window. In a practical sense, merchants often have a week or less in which to work. And, missing the response deadline results in an automatic loss, regardless of how strong the merchant's evidence might be.

Chargeback Response Time Limits: How Long Merchants Have to Respond to Disputes

When a chargeback hits your account, the clock starts immediately. Miss the response deadline, and it won’t matter how strong your evidence might be. You lose by default.

No second chances. No extensions offered. No excuses accepted.

Each card network sets its own timeframe for merchant responses, and these windows are shorter than you might expect. While cardholders often have 120 days or more to file a dispute, merchants typically get just 20 to 45 days to respond. Factor in the lag between when a chargeback is filed and when you're actually notified, and that window shrinks even more. In a practical sense, you might have a week (or even less) to submit your response.

Understanding these deadlines isn’t just about avoiding automatic losses. It’s about building internal processes that give you enough time to assess whether a dispute is worth fighting, and then submit a compelling response. Below, I’m going to break down the response time limits for each major card network so you know how much runway you have, according to card network rules, at least.

Chargeback Time Limits

In this post, we’ll take a look at how chargeback time limits work for both merchants and cardholders. We’ll also talk about circumstances that can alter the normal time frames and see why these deadlines are so important.

Dispute Time Limits vs. Response Time Limits

TL;DR

Cardholders have much more time to open a dispute than merchants have to respond to it. Depending on the issuer or payment platform, cardholders may have as few as 60 days, or as many as 540 days, to dispute a transaction. Response time limits for merchants are far shorter. They range from 7 days in the case of PayPal to 45 days for Mastercard.

As we mentioned earlier, it’s not just the card networks that can control the time frames for chargebacks. Banks have to meet the deadlines, too, and they may move up the merchant’s deadline to buy themselves a little more time.

For example, a Chase Bank cardholder will only have 60 days to dispute a transaction, despite the network’s limit being 120 days. The networks say merchants have a 45-day response window, but the Chase credit card chargeback time limit for merchants is 39 days.

On the other hand, PayPal — which can serve as a credit card processor for merchants — allows buyers up to 180 days to file a claim. That’s 50% more time than what the major card networks allow. The merchant, however, must respond within seven days.

There are two other points to consider here as well. First, while the chargeback time limit starts on “Day One” of each phase, merchants may not actually receive notice until a few days later. They may also need to leave 2-3 days for actual delivery, depending on the submission method. As one can see, a 30-day window can get much smaller very quickly.

Second, the point that qualifies as “Day One” will reset at each stage of the chargeback process. So, while the time limit on chargebacks is predetermined, it will still move around as one progresses to a different stage of the dispute:

We cannot stress this enough: All the limits presented here are based on the most current information available. They are subject to change and may or may not apply in individual situations. Always check the documentation provided by your processor to verify the deadline for your response.

Response Time Limits by Card Brand

The card networks themselves have the most influence when it comes to regulating chargeback response timeframes. Each card brand has its own rules and uses its own terminology, even if the core elements are the same.

Remember, any network timeframe could be subject to exceptions.

Mastercard Chargeback Response Time Limits

Merchants and acquirers generally have 45 days to respond to each phase of a Mastercard chargeback. An important exception is a request for information concerning a dispute. Merchants only have 18 days to respond to this.

Visa Chargeback Response Time Limits

Acquirers and merchants must respond within 30 days of Day One for each phase. The one exception is the timeframe for arbitration, which has the tightest deadline of all. If a party wants to escalate a dispute to arbitration, they must do so within 10 days.

Amex Chargeback Response Time Limits

When a card member contacts American Express about a dispute, the bank side of the company will either file the chargeback or send the merchant an inquiry. They then have 20 days to respond to the inquiry, either accepting the dispute or offering evidence that the chargeback is invalid.

Important!

In most instances, Amex will simply escalate the case straight to a chargeback. The company doesn’t have the same complex mechanism for merchants to contest disputes. If the bank decides the chargeback is legitimate, the merchant can’t really appeal to the card network, as the two are one and the same.

Discover Chargeback Response Time Limits

The merchant has 20 days for initial Discover responses. However, individual banks and processors may be more strict with timelines.

If there is a second chargeback, the merchant has 30 days to submit additional documents. Merchants have 15 calendar days to request that the case progress to Discover arbitration.

UnionPay Chargeback Response Time Limits

In most cases, you have 30 days to respond to a chargeback filed on a UnionPay transaction. If the issuer rejects your response, and you want to escalate it to arbitration, you have just 5 days to respond and convey this to your processor.

Chargeback Time Limits: One More Thing to Worry About

Like other parts of the process, learning all the types and exceptions of chargeback time limits will take a lot of effort and money. Understanding chargeback time limits is a critical part of recovering revenue, though. Without knowing how different banks, card schemes, and reason codes affect the timeframe, it’s extremely easy to miss a deadline…and automatically lose a case.

Most merchants find it hard to try and handle chargebacks in-house. Deadlines are firm, but they’re not standardized. One issuer may closely follow card scheme guidelines, while another may enact their own, stricter rules. Disputes can blindside a merchant months after the transaction was settled.

For merchants, it can seem like a no-win situation. Contesting chargebacks takes a lot of time and resources, with no guarantee of success. At the same time, not fighting illegitimate chargebacks is essentially throwing away revenue. This balancing act often leaves merchants feeling helpless.

Outsourcing the task of chargeback representment ensures a much higher win rate. In fact, Chargebacks911® offers a guaranteed ROI for all chargeback disputes we compile on the merchant's behalf.
