General
What Mastercard Reason Code 4808 Means
Mastercard reason code 4808 covers disputes tied to authorization problems, such as a transaction that was not properly authorized, was declined at authorization, or was cleared after the authorization had expired.
Why This Chargeback Happens
This dispute commonly occurs when a merchant forces or completes a sale despite a declined or expired authorization, when the authorized and cleared amounts diverge beyond allowed tolerances, or when required authorization was never obtained.
What the Cardholder or Issuer Is Claiming
The issuer is asserting that the transaction did not have valid authorization at the time it was completed and cleared, and is therefore recoverable.
What Merchants Should Review
Review the authorization response codes, the timing between authorization and clearing, the authorized amount versus the settled amount, and any stand-in or forced-post activity recorded by your terminal or gateway.
Recommended Chargeback Evidence
- Authorization approval codes matching the settled transaction
- Records showing the transaction cleared within the authorization validity window
- Documentation that the authorized and settled amounts align within tolerance
- Terminal or gateway logs confirming a valid approval response
How to Prevent Similar Disputes
Authorization disputes may be reduced by clearing transactions within the authorization validity period, never forcing sales after a decline, obtaining fresh authorization when amounts change materially, and reviewing response codes before completing a sale.
