What Mastercard Reason Code 4855 Means
Mastercard reason code 4855 is titled Goods or Services Not Provided and falls under the Consumer Disputes category. It is filed when a cardholder claims they paid for physical goods, digital products, or services that were never delivered or made available to them. This is Mastercard's primary non-delivery code and one of the most common consumer dispute codes on the network.
The dispute premise is straightforward: payment was made but the merchant failed to fulfill their end of the transaction. The merchant's burden is to demonstrate that delivery occurred — that the goods were shipped and confirmed delivered, or that the service was rendered and accessible. Without delivery evidence, the dispute is nearly impossible to win.
Code 4855 means the goods were never received. If the cardholder received the goods but has a quality complaint, that is 4853 (Cardholder Dispute). If the transaction was cancelled but a charge still occurred, look at 4841. Filing the wrong response strategy for the wrong code wastes your entire response window.

| Discover | NF | Non-Receipt of Goods/Services | Direct equivalent; similar timeframes and evidence |
Common Trigger Scenarios
- Lost shipment with no delivery confirmation. The carrier's tracking shows the package as "in transit" or "exception" rather than "delivered." The cardholder has waited past the expected delivery date and filed a chargeback. Without a "delivered" scan, the merchant has limited recourse.
- Delivered to wrong address. The shipment was delivered, but tracking shows delivery to a location different from the cardholder's address. The cardholder correctly claims non-receipt because the package went to the wrong place.
- Friendly fraud on confirmed delivery. Tracking shows confirmed delivery to the correct address, but the cardholder claims non-receipt. May be intentional fraud, package theft at the door, or a household member intercepting the package without the cardholder's knowledge.
- Digital product access failure. A software license key failed to activate, a streaming subscription could not be accessed due to a technical error, or a digital download link was broken. The cardholder paid but cannot access what they purchased.
- Service never rendered. A contractor was paid in advance but did not perform the work, a class or event was cancelled without a refund, or a subscription service failed to activate despite successful payment.

Evidence You Will Need
Delivery proof is the foundation of any 4855 defense. Gather carrier records and supplemental evidence before drafting your response.
- Carrier tracking showing confirmed delivery to the cardholder's address — "delivered" status, not "in transit" or "out for delivery"
- Signed delivery receipt if signature was captured at delivery — particularly valuable for high-value orders and significantly increases win rates
- Photo proof of delivery from carriers like UPS, FedEx, or USPS showing the package at the delivery address
- For digital goods: IP address logs, login timestamps, download records, or access confirmation showing the cardholder connected to and used the product after purchase
- AVS match confirmation showing the shipping address matches the billing address, establishing delivery was to the correct cardholder location
- Post-purchase customer communication implying receipt — a return request, a product support question, or any contact referencing the received item

Learn exactly how to package and present this evidence →How Merchants Lose This Dispute
- Tracking shows shipped but not delivered. A tracking number showing the label was created or the package was picked up is not sufficient. Mastercard requires proof of delivery, not proof of shipment. "In transit" loses disputes.
- Delivery confirmed to a different address than billing. If you shipped to an alternate address without explicit documentation of the cardholder authorizing that address, delivery to a third-party location is not proof of delivery to the cardholder.
- No tracking on low-cost items leading to high losses. Merchants who use untracked shipping on small-value orders to save on postage lose every 4855 dispute filed against those orders. The economics of tracking vs. chargeback losses don't support going untracked above minimal order values.
- Late response to the dispute. Mastercard's 45-day merchant response window is longer than Visa's, but processors often impose internal deadlines of 7-14 days. Missing your processor's deadline means automatic loss regardless of how strong your evidence is.

Get the step-by-step winning strategy →Response Framework Overview
- Assert delivery was completed. Open by stating the goods were shipped and confirmed delivered to the cardholder's address on a specific date.
- Present carrier tracking confirmation. Lead with the tracking number showing "delivered" status, delivery date, and delivery address matching the cardholder's address.
- Include signature or photo proof if available. Attach the delivery confirmation image or signed receipt if your carrier captured it.
- Reference AVS match. Confirm the delivery address matches the AVS-verified billing address, establishing the correct cardholder location was used.
- Note any post-delivery contact. If the cardholder contacted you after the delivery date about anything related to the order, include this as implicit confirmation of receipt.
Prevention Tips
- Use tracked shipping with delivery confirmation on every order. This is non-negotiable for any merchant above minimal average order values. Untracked orders are an open invitation to 4855 chargebacks with no defense.
- Require signature on high-value orders. Signature confirmation dramatically increases win rates for 4855 disputes on orders over $200-$250 and effectively deters friendly fraud on high-value items.
- Send delivery notifications proactively. Automated emails at "shipped," "out for delivery," and "delivered" stages reduce cardholder anxiety and give customers a direct channel to alert you of delivery issues before contacting their bank.
- Make customer service accessible. A customer who can reach you easily will resolve a non-delivery issue with you rather than their issuer. One resolved customer service ticket beats one chargeback every time.
Frequently Asked Questions
What is the difference between Mastercard 4855 and 4853?
Code 4855 is specifically for non-delivery — the cardholder claims they never received goods or services at all. Code 4853 is Mastercard's broader cardholder dispute code that covers quality complaints, not-as-described claims, and other consumer dissatisfaction issues. If the package arrived and the customer is unhappy with it, that's 4853. If it never arrived, that's 4855.
How does Mastercard 4855 compare to Visa 13.1?
They are functionally equivalent non-delivery codes. The evidence requirements are essentially the same: carrier tracking with delivery confirmation, signed receipts, and for digital goods, access logs. Mastercard allows 120 days from the expected delivery date, aligning closely with Visa's window. The same evidence package works for both codes.
Does 4855 apply to digital goods and services?
Yes. For digital products, delivery proof means demonstrating the customer accessed, downloaded, or used the product — IP address logs, login timestamps, download records, or streaming activity logs. The burden is the same as physical goods: prove the product or service was actually delivered and available to the cardholder.
What if delivery is pending beyond the expected date when the dispute arrives?
Contact the cardholder immediately and offer options: wait for delivery with a firm new date, or cancel and refund. Proactive communication before the cardholder contacts their bank prevents most 4855 disputes from being filed in the first place.
