Discover 4863 chargeback: Authorization Non-Compliance explained

Checked

Discover reason code 4863, Authorization Non-Compliance (older letter code AT), means the sale was not properly authorized or was made after the card expired. Fiserv's guide gives the issuer 120 days. Answer with proof of a positive authorization response, and proof the sale happened before the card's expiry date. Authorizing every charge, including renewals, prevents it.

What PlatformDTC does

PlatformDTC authorizes every card payment through the processor at checkout and on every subscription renewal, so each order carries its own authorization. PlatformDTC answers this kind of dispute with its standard evidence pack built from the order: customer name, email, IP address, billing and shipping address, items bought, carrier, tracking and ship date, the refund policy, and any refund already issued. With "Answer a chargeback automatically" switched on, it sends the response to the bank for you before the deadline.

What it means

The issuer says there was no valid authorization. Stripe maps it to general; Braintree lists it as fraud.

Older Discover documentation pairs 4863 with the letter code AT.

Why customers file it

Charging without authorization, or charging an expired card.

Evidence that wins

Respond to every Discover chargeback, even small ones, as Discover itself advises. Send:

  • Proof of a positive authorization response
  • Proof the sale occurred before the card expired

How to prevent it

  • Authorize every charge
  • Update expired cards before renewals

For developers

On Stripe the dispute object arrives with reason "general" and the card network's own code in payment_method_details.card.network_reason_code; listen for charge.dispute.created and read evidence_details.due_by for the deadline.

Discover does not publish its dispute rules publicly; the codes and names here are the ones Stripe reports, and the defences come from processor guides.

Frequently asked questions

Is Discover 4863 the same as Mastercard 4863?
No. Discover 4863 is Authorization Non-Compliance; Mastercard's old 4863 meant the cardholder did not recognise the charge.
Is it defendable?
Fiserv lists defences; Adyen marks it as not defendable through Adyen.
