Evidence pack by reason family
GuideEvidence by reason familyBack to article
Visa/MC Compelling Evidence shape. Fight the family, not the reseller label.
| Family | Typical codes | What wins | Default move |
|---|---|---|---|
| Fraud | Visa 10.4 / MC 4837 | 3DS success, AVS/CVV, device, fulfillment | Fight if auth is clean; refund if unshipped |
| Authorization | Visa 11.x / MC 4808 | Auth receipt that matches capture | Credit and close unless the receipt matches |
| Processing | Visa 12.x / MC 4834 | Correct amount, currency, duplicate proof | Credit the delta; do not write a novel |
| Not received | Visa 13.1 / MC 4855 | Carrier scan, delivery photo, AVS match | Fight if delivered; refund if in warehouse |
| Not as described | Visa 13.3 / MC 4853 | SKU, listing, CS transcript, return policy shown | Refund if the page lied; fight if it did not |
| Cancelled recurring | Visa 13.2 / MC 4841 | Cancel log, last MIT, refund of unused cycles | Cancel the token first, then credit |
| Credit not processed | Visa 13.6 / MC 4860 | Refund confirmation in the processor | Post the credit; do not fight a missing refund |
Filter by family or search the network code. Each row names typical Visa/Mastercard codes, what actually wins, and a default move. Do not send a 3DS packet on not-as-described. Do not fight cancelled-recurring while MIT still bills.
Pairing procedure: Build the fight packet the family needs. Related: Reason codes that matter. Visa 10.4 priors: CE 3.0 prior-transaction checklist. Topic: Chargebacks.
