Verifi CDRN

TL;DR
  • You stay in control. Nothing fires on its own. Every alert lands in a queue and you decide, case by case. RDR is the opposite.
  • About 72 hours to refund. Refund inside the window and no chargeback gets filed. Miss it and you get a regular chargeback, same as always.
  • $20-40 per alert. You buy it from a reseller, never from Visa.
  • US-focused. Strongest on domestic Visa and Discover volume. Selling internationally? Ethoca is the one you want.
  • You pay per alert, not per chargeback you stopped. Every alert bills you, including the ones you'd have won.
  • Activation runs 3-7 business days. A next-month lever, not a today lever.

One of your customers just called their bank instead of calling you. CDRN is the tip-off. You get a heads-up before the chargeback lands, plus about 72 hours to refund and make it go away. (It stands for Cardholder Dispute Resolution Network, which nobody says out loud.)

Refund in time and nothing hits your chargeback ratio. Ignore the alert and you land where you'd have been anyway. A normal chargeback, except now you've also paid for the warning that told you it was coming.

CDRN is run by Verifi, which Visa owns. That's why coverage is strongest on Visa cards, and why RDR comes out of the same building.

An alert isn't bad news

Getting alerts means the thing you bought is working. That customer was calling their bank either way. Before alerts, you'd have found out 30 days later, when the chargeback showed up on your statement. Now you find out while you can still fix it.

How It Works​

  1. Your customer contacts their bank about a charge.
  2. If that bank is in the network, an alert gets routed to you.
  3. You have roughly 72 hours to refund.
  4. Refund, and the dispute never becomes a chargeback.
  5. Ignore it, and it proceeds like any other chargeback.

The alert names the transaction. You issue the refund in your own processor dashboard:

ProcessorWhere to refund
StripePayments > the payment > Refund
SquareTransactions > the transaction > Issue Refund
PayPalActivity > the transaction > Issue a refund
Shopify PaymentsOrders > the order > Refund
Anyone elseFind the original sale and refund the full amount. A partial refund leaves the dispute alive

Some resellers issue the refund for you, plugged straight into your processor. Ask which setup you're getting before you sign.

What It Covers​

Strongest on US Visa and Discover volume, with some Mastercard. What you actually get depends on which banks your customers use. No vendor can promise full coverage.

Here's the honest limit. An alert only fires if your customer's own bank, their issuer, is in the network. A dispute from a bank outside it arrives cold, as a chargeback, exactly like it always did. Expect a mix of both. Don't let a salesperson tell you coverage is airtight.

For international volume, CDRN is the wrong tool. Ethoca has the broader global reach.

What It Costs​

Typically $20-40 per alert through a reseller, moving with your volume. You get billed for every alert that lands, win or lose.

You pay for the ones you'd have won. You've got signed delivery and a solid representment case, and you refund anyway because the alert showed up. You just paid $30 to lose on purpose.

You can also pay twice for one angry customer. CDRN and Ethoca overlap. De-duplication is your reseller catching that both networks fired on the same dispute. Run both without it and one complaint bills you twice. Most resellers de-dupe automatically. Ask anyway, in writing: "If CDRN and Ethoca both fire on one dispute, am I billed once or twice?" Get the answer in the contract, not on the sales call.

CDRN vs RDR​

Both come from Verifi, and both are Visa-adjacent. That's why people mix them up. The difference is who makes the call.

GeographyUS-focusedGlobal
Cost~$20-40/alert~$15-25/case

Pick CDRN if somebody will actually work the queue. You keep judgment over each dispute.

Pick RDR if nobody's opening those alerts inside 72 hours. An alert you never work is money you set on fire.

Merchants get that second one wrong most often. CDRN only pays off if a human responds every day. Including the days you're slammed. If that human is you, be honest. Automation beats a queue nobody opens.

The VAMP Catch​

Refunding on a CDRN alert stops the chargeback. The dispute stays off your ratio. It doesn't erase the fraud report.

Say your customer told their bank the charge was fraudulent. A TC40 got filed, and TC40s still count under Visa's VAMP program. So alerts are excellent against billing confusion and service complaints. They're half a fix for fraud claims. If your ratio problem is fraud-driven, alerts won't get you out of it. You need 3D Secure or better screening upstream.

How to Actually Buy It​

You can't buy CDRN from Visa. Verifi owns the rails, but below enterprise scale you buy through a reseller. That's a middleman platform bundling CDRN, Ethoca and RDR into one dashboard and one invoice. Chargebacks911, Chargeblast and Chargeflow all do this, and some processors resell it too. See Chargeback Vendors for the wider landscape.

Midigator isn't on that list any more

Older versions of this page named Midigator as a reseller. Equifax acquired Midigator in 2022 and folded it into Kount. As of 2 August 2026, midigator.com 301-redirects to kount.com. Kount then 301-redirects to equifax.com/business/identity-fraud/. If someone pitches you Midigator alerts, ask which Equifax entity the contract sits with. Redirect chains observed 2026-08-02.

Get quotes from two or three. Send all of them the same four questions. Make them answer in writing:

  1. "What's the per-alert price at my volume, and what does it drop to as volume grows?"
  2. "Do you de-duplicate CDRN against Ethoca? If both fire on one dispute, am I billed once or twice?"
  3. "Who issues the refund, you through a connection to my processor, or me by hand?"
  4. "What's the minimum term, and how much notice do I give to cancel?"

Then demand three things in the contract. The per-alert price. The de-duplication answer in writing. A term you can walk away from. If a rep says "we handle that" and won't put it on paper, walk.

Budget 3-7 business days from signature to your first alert.

Where This Breaks​

  1. Your customer's bank isn't in the network. No alert fires, and the chargeback arrives with no warning. Coverage is real but partial, whatever the sales deck says.
  2. Nobody opens the queue. An expired alert costs the fee and prevents nothing. You pay for the alert AND the chargeback. That's the most common way merchants waste money on CDRN.
  3. The dispute is real fraud. You stop the chargeback, the TC40 stays, and your VAMP count barely moves. Fix that upstream, not here.
  4. Your product is the problem. Customers dispute because what you sold them was bad. Alerts just make you pay for the same complaint twice. Fix the product.

Test to Run​

Run it for 30 days. Log every alert: the date it landed, the date you refunded, the amount.

  • Over 80% refunded inside the window: CDRN is earning its money. Keep it.
  • Under 80%: you don't have a CDRN problem, you have a staffing problem. Move to RDR and stop paying for alerts nobody opens.

Scale Callout​

VolumeFocus
Under $100K/moSkip alerts. Fix your descriptor, turn on the free enrichment tools, make refunds easy to get. Add RDR if your ratio passes 0.5%
$100K-$1M/moCDRN works here if you're US-focused and one named person owns the queue daily. Otherwise RDR
Over $1M/moCDRN plus Ethoca through one reseller, de-duplicated. Queue coverage is somebody's actual job

Next Steps​

  1. Check your ratio and find out whether you need alerts at all.
  2. Fix your descriptor first if you haven't. It's free. "I don't recognize this charge" is the most common dispute you can prevent.
  3. Compare all three services before you buy.
  4. Setup Dispute Alerts playbook for the implementation steps.
