Mastercard reason code 4808:
Authorization-Related Chargeback

What Mastercard 4808 means

Mastercard's single authorization-related chargeback. It covers required authorization not obtained, an expired chargeback protection period on an account not in good standing, offline or refund transactions presented late, improper stand-in or X-code approvals after a decline, CAT 3 devices and transit first-ride risk.

Common causes

• Capturing more than seven days after a final authorization, or more than 30 days after a preauthorization
• Processing a refund more than five days after it was agreed
• Forcing through a transaction that was declined
• Capturing without any authorization

Evidence that answers it

• Processor record of an approved authorization matching the clearing record
• Proof that one authorization legitimately covered several clearing records (split shipments)
• Proof the chargeback protection period had not expired at presentment
• Proof the issuer approved after previously declining
• Proof of a refund issued before the chargeback

How to prevent it

• Capture within the authorization protection period, or reauthorize first
• Process refunds within days of agreeing to them
• Never resubmit a declined authorization without a fresh approval

Time limits and caveats

Issuer time frame: generally within 90 days of the settlement or Central Site Business Date (120 days for some European ATM and Maestro transactions). Second presentment within 45 days. Pre-arbitration is optional for 4808; the issuer can go straight to arbitration.
