If you accept Discover cards, treat disputes differently — 3 practical steps (respond to retrievals in 20 days)

Quick, practical takeaways from our Discover chargeback guide you can use right now:

1. Assume Discover is the issuer and the network — use DNDS as your single dispute hub and retain full transaction evidence for at least 540 days (and up to 2 years if you want to cover Good Faith Investigations). Capture order timestamps, delivery promises, tracking logs, and any customer communications so you can assemble an evidence packet fast.
2. Treat retrieval requests as mission-critical: you have 20 calendar days to submit evidence (chargeback responses are 5 days). If you miss a retrieval request you auto-lose and cannot fight some fraud codes (AA, UA01, UA02, UA05, UA06). Automate DNDS alerts, prepare a templated evidence packet, and assign a fast owner to prevent misses.
3. Use Discover’s mitigation tools but balance friction: enable Enhanced Decisioning to pass richer auth data, roll out ProtectBuy (3DS) with exemption rules to limit checkout friction, and subscribe to Fraud Alerts (Standard or Premium) with a clear playbook to cancel shipments or issue refunds immediately when flagged.
