Mastercard Reason Code 4855: Goods or Services Not Provided

What Mastercard reason code 4855 means

4855 is a legacy cardholder-dispute code for non-receipt. The cardholder made the purchase and isn’t claiming fraud. They say the merchandise never arrived, the digital product was never delivered, or the service never happened. It also covers merchants who stop trading before fulfilling orders.

Mastercard now handles this as the “goods or services not provided” sub-scenario of 4853 Cardholder Dispute. It’s the Mastercard counterpart of Visa’s 13.1.

Timing matters. The cardholder generally can’t dispute non-receipt before the promised delivery date has passed, and the 120-day window can run from the expected delivery date rather than the transaction date. In some situations the issuer must wait a set period before charging back. Confirm specifics with your acquirer.

Common causes

• Packages marked delivered but taken from a porch or mailroom
• Slow or lost shipments with no proactive tracking update
• Pre-orders or backorders where the expected date passed without communication
• Digital products where the access email went to spam
• Events or services that were cancelled or rescheduled
• Friendly fraud: the item arrived and the customer claims it didn’t

Evidence that wins a 4855 dispute

1. Carrier tracking with delivery confirmation to the shipping address on the order, including delivery date.
2. Signature or photo proof of delivery for higher-value orders.
3. The order record showing the shipping address the cardholder entered at checkout, ideally matching their billing address.
4. Shipping confirmation email sent with the tracking link.
5. For digital goods: access-email delivery, download logs, logins, IP address and usage.
6. For services: booking records, attendance or completion records, or proof the service was available on the agreed date.
7. Customer communication, especially if they confirmed receipt or never contacted support.

How to prevent 4855 chargebacks

• Email tracking at shipment and again at delivery.
• Require a signature on high-value orders.
• Give realistic delivery dates on pre-orders and update customers when they slip.
• Send digital access details from a recognizable sender, and show them on-screen after purchase.
• Answer “where’s my order?” tickets the same day. Many not-received disputes start as unanswered support emails.

Should you fight or accept?

Fight when tracking shows delivery to the order address, or you have access logs for a digital product. These disputes are highly winnable with good tracking.

Accept when you can’t show delivery: the shipment was lost, tracking stops in transit, or the delivery date passed without fulfillment. Refund or reship, and file a carrier claim where you can. Delivered-but-stolen cases sit in between: tracking usually wins, but a pattern of them points to a shipping-method problem.
