TL;DR
- RDR, CDRN and Ethoca are chargeback alert networks: each lets you refund a customer's dispute before it becomes a chargeback, so it never counts as one.
- RDR is Visa's automatic option: rules you set refund matching disputes in as little as a second. CDRN, also from Visa's Verifi, sends the case to you to refund by hand within 72 hours, on Visa and other card brands. Ethoca is Mastercard's network.
- All three keep the dispute off your record. None removes a fraud report the customer's bank has already filed with Visa; only Compelling Evidence 3.0 does that.
- Stripe includes RDR and Ethoca, priced per resolution (each dispute settled by refund before it becomes a chargeback), but not CDRN. Other processors and alert providers offer different combinations.
- A subscription business taking Visa and Mastercard needs at least one Visa tool and Ethoca, and should cancel the subscription behind every refunded alert.
Who this helps: you run a subscription business, you're comparing chargeback alert options or reading your processor's dispute prevention settings, and you want to know what each network does and which ones you need.
A chargeback alert is a warning that arrives before the chargeback does. Three networks send them, two run by Visa and one by Mastercard, and they work differently enough that picking the wrong mix leaves a gap. Here is how RDR, CDRN and Ethoca compare, what they cost, and what a subscription business needs.
What are RDR, CDRN and Ethoca?
RDR, CDRN and Ethoca are the three chargeback alert networks, also called pre-chargeback or pre-dispute alerts: each warns you about a dispute before it becomes a chargeback, so you can refund instead. Visa's two chargeback alerts, RDR and CDRN, come from Verifi, the Visa company behind Visa's dispute tools, and Ethoca comes from Mastercard.
Each one sits between the customer's bank and the chargeback. A customer asks their bank to reverse a charge, and if the bank takes part in the network, the case reaches you or your rules first; a refund then closes it before a chargeback is filed.
RDR vs CDRN vs Ethoca (as of October 2026)
| RDR | CDRN | Ethoca | |
|---|---|---|---|
| Run by | Visa, through Verifi | Verifi, a Visa company | Mastercard |
| Card brands | Visa only | Visa and other brands, where the bank takes part | Mastercard, plus Visa banks that take part |
| Who decides | Your rules, automatically | You, case by case | You, or your rules on some processors |
| Time to act | Nothing to do; it resolves in as little as a second | 72 hours | 24 to 72 hours |
| Where it is resolved | At Visa, through your acquirer | With you; it never reaches your acquirer | With you or your processor's rules |
| Your record | Kept out of Visa's dispute count | No dispute is filed | No chargeback is filed |
| A Visa fraud report already filed | Still counts | Still counts | Still counts |
| On Stripe | Built inper resolution | Not offered | Built inper resolution |
What is RDR?
Rapid Dispute Resolution (RDR) is Visa's automatic option. You set rules in advance, such as refunding every dispute under a certain amount or of a certain type, and Visa resolves matching disputes in as little as a second, before they become chargebacks.
The case runs through your acquirer (the bank that holds your merchant account), so nothing lands in your queue, and Verifi allows up to ten rules per merchant account. RDR covers Visa only, and on Stripe it cannot resolve a partial dispute or a charge you have already refunded, so those cases still need an answer. Our guide to Visa RDR covers the rules in detail.
What is CDRN?
The Cardholder Dispute Resolution Network (CDRN) is Verifi's manual option. When a participating bank receives a dispute, the case is paused and sent to you, and you have 72 hours to refund it before it goes ahead.
Unlike RDR, CDRN works on Visa and other card brands, and the case never reaches your acquirer. That makes it the tool for disputes you want to look at first: an annual plan, a large charge, or a customer you might keep. Coverage depends on which banks take part, and CDRN is not part of Stripe's built-in dispute prevention, so a Stripe merchant who wants it needs a separate provider.
What is Ethoca?
Ethoca is Mastercard's alert network. A bank in the network sends you a customer's dispute or a confirmed fraud case, and a refund before the chargeback is filed keeps it out of Mastercard's Excessive Chargeback Program count.
Ethoca's coverage is strongest on Mastercard and includes Visa banks that have joined its network. On Stripe, Ethoca resolutions run on rules you set, and those rules only apply to chargebacks started after you enroll. Our guide to Ethoca covers its limits.
Which alerts does a subscription business need?
At least one tool for each card brand you take, because no single network covers every brand fully. For Visa that is RDR, CDRN or both, and for Mastercard it is Ethoca.
Theo sells a journaling app at $12 a month or $120 a year. His RDR rule refunds every Visa dispute under $20 automatically, which covers the monthly plan and leaves the annual plan out; when an annual-plan dispute arrives through CDRN, he has 72 hours to check the customer's usage and decide. Ethoca covers his Mastercard customers, and he cancels the subscription behind every refunded alert, so the same customer cannot dispute next month's renewal.
How do you turn on RDR, CDRN and Ethoca?
Where you turn them on depends on where you process payments. On Stripe, you turn on dispute prevention in your Dispute settings and set the rules that decide which disputes are refunded in Radar, which covers RDR on Visa and Ethoca Alerts on Mastercard.
On other processors, ask whether your processor or acquirer supports RDR. CDRN and Ethoca are also sold directly by Verifi and Ethoca and through partners that resell them, which is how a Stripe merchant adds CDRN. Our guide to chargeback management covers the other jobs around alerts.
Is an alert cheaper than a chargeback?
Not by much on a small renewal, and that is the honest way to judge them. Refunding through an alert costs about what a lost chargeback would; what the alert buys is a clean record.
A chargeback you fight and win costs less, $15 at Stripe, but it still leaves the mark, and on a $12 renewal you would need to win more than 56% of your fights for fighting to pay. The record is what matters: Visa's monitoring program, VAMP, counts disputes and fraud reports against your sales, and Visa can identify a merchant from 0.5% when its acquirer is flagged. Once you are in VAMP, each dispute kept off the record also avoids an $8 fee, and the alert becomes the cheaper option outright. Our guide to chargeback fees works through the same math at other prices.
How much do RDR, CDRN and Ethoca cost?
Pricing depends on who sells them, in one of two models: per alert, charged when an alert arrives, or per resolution, charged only when a dispute is settled by refund before it becomes a chargeback. RDR is not free under either.
Stripe charges per resolution and publishes its prices; its Canadian disclosures list CA$15 per Visa resolution through RDR and CA$29 per Mastercard resolution through Ethoca, and Stripe lists a separate fee for each Compelling Evidence 3.0 block. Providers that sell all three networks may charge per alert, including on alerts you decide not to refund, and some add setup or monthly fees, so compare the cost per prevented chargeback rather than the price per alert.
What do alerts do to your VAMP and Mastercard numbers?
Alerts keep the dispute out, but not the fraud report. An RDR resolution is excluded from Visa's dispute count, a CDRN refund means no dispute is filed, and an Ethoca refund means no chargeback for Mastercard's program to count.
The gap is fraud claims on Visa cards. When a customer says a charge was not theirs, the bank files a fraud report, a TC40, and it still counts toward VAMP after any alert refund. Only Compelling Evidence 3.0 removes it, which is why alerts and Compelling Evidence 3.0 work best together on a subscription business's fraud claims.
Why do some disputes trigger two alerts?
Because the networks overlap. A dispute can reach you through more than one network, so it can be billed twice and, if you refund by hand, refunded twice.
CDRN and Ethoca both reach some of the same banks, and Verifi lists fewer duplicate refunds among the reasons to run CDRN and RDR together; RDR itself will not resolve a charge that has already been refunded. Before refunding a CDRN or Ethoca alert by hand, check whether the charge is already refunded, and if you use a provider for all three, ask how it handles duplicates. The reverse holds too: once RDR has resolved a charge, don't refund it by hand, because Visa's 2026 merchant guide warns that a second refund credits the customer twice.
What should you do with each alert?
Refund it, cancel the subscription behind it, and record the outcome, in that order; on RDR the refund happens automatically, so skip straight to canceling. Four habits make alerts work for a subscription business.
- Cancel the subscription. A refund without a cancellation leaves the next renewal free to become the next dispute.
- Report the outcome. Ethoca asks merchants to report what they did with each alert, such as refunded or not settled.
- Watch the ones alerts can't stop. Track fraud reports and PayPal disputes separately, and check your VAMP ratio each month.
- Fix the cause. Repeated alerts on the same plan point to a billing problem, such as an unclear statement descriptor or a renewal customers forget, which our prevention playbook covers.
FAQ
What is the difference between RDR and CDRN?
RDR is automatic and Visa only: rules you set refund matching disputes in as little as a second, through your acquirer. CDRN is manual and works on Visa and other card brands: the case is paused and sent to you, and you have 72 hours to refund it.
What is CDRN?
CDRN, the Cardholder Dispute Resolution Network, is Verifi's manual chargeback alert. When a participating bank receives a dispute, the case is paused and sent to the merchant, who has 72 hours to refund it before it becomes a chargeback.
What is the difference between Ethoca and Verifi?
Ethoca is Mastercard's alert network and Verifi is the Visa company behind RDR and CDRN. Ethoca covers Mastercard plus Visa banks that have joined it; Verifi's RDR covers Visa only and its CDRN covers Visa and other card brands.
Does RDR work on Mastercard?
No. RDR is Visa only. For Mastercard disputes, use Ethoca.
Is RDR free?
No. Processors and alert providers charge for RDR, either per resolution or per alert. Stripe, for example, charges per Visa resolution and publishes the price for each country.
Does Stripe offer RDR and Ethoca?
Yes. Stripe's dispute prevention includes Visa RDR and Ethoca Alerts, charged per resolution: you turn it on in Dispute settings and set the refund rules in Radar. It does not include CDRN.
Do Shopify stores get chargeback alerts?
Shopify Payments has its own network dispute resolution program. Shopify can enroll a store automatically once its chargeback rate reaches 1.5% over 90 days, charges $15 in the US for each dispute resolved, and counts those disputes in its own chargeback rate. Its help page doesn't say which networks it uses.
Do chargeback alerts lower my VAMP ratio?
Alerts keep the dispute out of it: an RDR resolution is excluded from Visa's count and a CDRN refund means no dispute is filed. A fraud report the bank already filed still counts unless it qualifies under Compelling Evidence 3.0.
Can one dispute trigger two alerts?
Yes. The networks overlap, and CDRN and Ethoca both reach some of the same banks, so one dispute can arrive twice and be billed twice. Check whether a charge is already refunded before refunding an alert by hand.
Do chargeback alerts work for American Express and Discover?
Only partly. American Express and Discover disputes reach you only when the customer's bank takes part in CDRN or Ethoca, and disputes opened inside PayPal reach no alert network at all.
Should I refund every chargeback alert?
Refund the ones you would lose or not fight, and cancel the subscription behind each. For annual plans and large charges, CDRN gives you 72 hours to check usage and decide whether to let the dispute proceed and fight it instead.
