Mastercard 4837 chargeback (no cardholder authorization): how to respond
By Zevron · 3 min read · Updated
What a 4837 dispute claims
Mastercard 4837 is the card-absent fraud dispute. The cardholder says they didn’t make the purchase and didn’t allow anyone to. Some of these are stolen cards. A large share, for subscription brands, are genuine customers who don’t recognize a renewal and file it as fraud because the bank’s form offered that option.
The first job is sorting the two. Real fraud shows up as a new account, a mismatched address and no history. A forgetful customer shows up as an account you can trace back months, with logins, deliveries and earlier payments they never disputed.
You get one submission on Shopify Payments and Stripe. Gather everything first and submit before the due date shown in the dispute.
The evidence that wins
| Evidence | Why it matters | Required |
|---|---|---|
| Order record | The disputed charge and the details the bank can check. | Yes |
| Customer history | Earlier undisputed orders from the same customer. | Yes |
| Device, IP or address match | Ties the disputed order to those earlier ones. | No, decisive when present |
| Carrier tracking | Delivery to a verified address. | No, strongly helps |
| Subscription record and usage | An active account the cardholder used. | No, helps |
The order to argue it in
- Address and CVV checks passed at authorization.
- The cardholder has a history of undisputed orders with the same device, IP, or address (Visa CE 3.0 when it qualifies).
- The goods were delivered to the cardholder's verified address.
Visa’s Compelling Evidence 3.0 is a Visa program. For Mastercard you argue from the same pattern of history without that program’s liability shift. Check your processor for any Mastercard-specific programs it supports.
A response template
The order [order #], [amount], was placed on [date] from IP [address] on device [id] and passed address and security-code checks at authorization (Exhibit A).
The cardholder has [n] earlier orders with us, none disputed, placed from the same [device / IP / shipping address] (Exhibit B).
The goods were delivered on [date] to [address], the address on the order (Exhibit C) [or: the account was used on [dates] (Exhibit C)].
The order was placed by the cardholder or with their authority. We ask that the dispute be resolved in the merchant’s favor.Mistakes that lose winnable 4837 cases
- Arguing the customer “must have” made the purchase without a record that ties them to it.
- Using an earlier order that was itself disputed.
- Matching only on name or email. Device, IP and shipping address are what the bank trusts.
- Not capturing IP and device at checkout, so there is nothing to match later.
- Fighting a case with no history at all. Accept the loss and tighten fraud screening.
