Mastercard reason code 4855
Mastercard 4855: Goods or Services Not Provided
What the cardholder is claiming
The cardholder says the goods or services never arrived.
The evidence that actually wins
Bank analysts skim responses in minutes against a checklist for this exact code. Lead with the strongest fact; never make them dig.
- ✓Carrier tracking with delivery confirmation to the order address
- ✓Digital goods: access, download, or usage logs tied to the buyer
- ✓Expected-delivery terms if the dispute is premature
The honest read
Like Visa 13.1: genuinely winnable with real delivery or usage proof, nearly hopeless without it. Deliver-to-a-freight-forwarder cases are the common heartbreaker; say so in the response and show what you have.
Nobody can promise you a win; the cardholder's bank decides. What you control is submitting the strongest complete case your records support, on time. Our plain-language guarantees say exactly what that means.
