Understanding Credit Card Chargebacks: Process, Timelines & Reason Codes
Chargebacks reverse transactions when cardholders dispute charges via their issuer (e.g., "item not received"). Governed by FTC Fair Credit Billing Act (60-day consumer window for errors) and networks like Visa/MC (120-day max), the process favors consumers but allows merchant rebuttals.
Flow: Cardholder files → Issuer credits → Acquirer notifies merchant → Merchant submits evidence (20-45 days) → Issuer decides → Possible arbitration (up to $500 fee to loser).
Visa thresholds: 0.65% triggers monitoring, 0.9% standard, 1.8% excessive (PaymentCloud). CFPB §1026.13 mandates issuer investigations for unauthorized use.
Common Chargeback Reason Codes (e.g., 13.1 Not Received)
- Visa 13.1 / MC 4853 (Item Not Received): Common for late/no delivery. Evidence: Full POD (signature + address match). Chargebacks911 notes high volume; mini case: Late shipments spike disputes--fix with adjusted fulfillment (FightDisputes).
- Visa 10.4 / MC 4837 (Fraud): IP logs, AVS prove authorization.
- Others: 13.2 (late delivery), quality issues (exclude if accepted, per CFPB).
Mini Case: Merchant faced 13.1 wave post-holidays; POD + comms emails won 70%.
Strongest Evidence Types for Merchants: Ranked by Effectiveness
86% chargebacks are friendly fraud (Kurv)--intentional but provable. Rank by win potential:
- POD Docs: Tracking + signature to cardholder address.
- Digital Receipts: Email confirmations with timestamps.
- IP Tracking Logs: Match transaction IP to cardholder (fraud proof).
- Video Surveillance: In-store pickup footage.
- Customer Comms: Emails/chats confirming receipt.
- Signatures: Digital verification (PDCflow).
Mini Case: 37 Signals changed descriptors to "37signals-charge.com," slashing chargebacks 30% via recognition.
Proof of Delivery & Digital Goods Evidence
Physical: Avoid basic tracking--use signed POD (Justt.ai). Poor example: "Delivered" without address proof loses.
Digital: Access logs, download confirmations. Crypto: Wallet matches (Justt.ai). No "tangible" POD? Comms + IPs win.
Evidence for Subscriptions & Fraudulent Chargebacks
Subscriptions: Billing consent emails, clear descriptors. Friendly fraud (£97B/year, Rapyd): 77% disputes (Chargeflow), 40% repeaters. Use IP/comms to link cardholder.
