What Discover Reason Code NF Means
Discover reason code NF — Non-Receipt of Goods or Services is filed when a cardholder claims they paid for goods or services that were never delivered or rendered. It applies across transaction types: physical goods not delivered to the cardholder's address; digital goods where download links, license keys, or access credentials were not provided or did not work; services that were scheduled and paid for but not performed; and travel or hospitality reservations that were charged but not honored.
NF disputes may be genuine (the delivery truly failed) or fraudulent (the cardholder received the goods and is filing in bad faith). Your evidence package must be strong enough to distinguish legitimate delivery from a false non-receipt claim.
The 120-day cardholder filing window runs from the expected delivery date for NF disputes, not just the transaction date. This means a delayed shipment can trigger a dispute months after the original purchase. Track your promised delivery dates carefully — they determine when your exposure window closes.

Common Trigger Scenarios
- Lost in transit. The carrier marked a package as in-transit but it never arrived. The cardholder disputes after the expected delivery date passes without delivery.
- Delivered to wrong address. The package was delivered to the wrong address due to a carrier error or an incorrect address entered at checkout. The cardholder never received it.
- Digital goods not delivered. The download link expired before the customer used it, the license key didn't work, or the access email went to spam — the cardholder disputes because they cannot access what they purchased.
- Service not performed. A contractor, cleaner, or service provider was paid in advance but did not show up or complete the work. The cardholder disputes the charge.
- Friendly fraud on delivered goods. The cardholder received the goods but claims non-receipt to get both the item and a refund. This is the most contentious scenario and requires strong delivery proof to defeat.
- Delayed delivery beyond cardholder's patience. Shipping delays cause the cardholder to dispute before the package arrives, particularly for international shipments or high-demand periods.
Key Deadlines & Timeframes
| Milestone | Timeframe | Notes |
|---|---|---|
| Cardholder Filing Window | 120 days | From the expected delivery date, not the transaction date |
| Merchant Response Window | 20 days | From chargeback notification; missing means automatic loss |
| Pre-Arbitration Window | 20 days | After merchant response, if Discover rejects representment |
| Proactive Resolution | Before dispute escalates | Reship or refund proactively to avoid chargeback fees |
Evidence You Will Need
- Carrier tracking record showing delivery — The primary evidence for physical goods. Provide the full tracking history from shipment to delivery, showing the delivery date, time, and address. Carrier delivery photos (where available) significantly strengthen your case.
- Shipping address match — Show that the delivery address matches the cardholder's billing address or an address the cardholder explicitly specified at checkout. Delivery to a freight forwarder or third-party address weakens your position.
- Digital delivery log — For digital goods, provide a timestamped server log showing when the download was initiated or the access credentials were used, along with the IP address of the access. This proves the cardholder accessed the content.
- Service completion documentation — For services, provide a signed work order, completion certificate, time-and-materials record, photos of completed work, or attendance record showing the service was delivered.
- Customer communication timeline — Any emails or messages between you and the cardholder — especially communications that acknowledge receipt, ask follow-up questions, or request changes after the delivery date.
- Expected delivery date documentation — Your order confirmation showing the promised delivery date and the actual delivery date, demonstrating the timeline was met or explaining any delay.

- No tracking number or delivery confirmation. If you shipped without tracking, you have no proof of delivery. Discover will side with the cardholder on non-receipt claims without delivery evidence.
- Tracking shows "in transit" — not delivered. A tracking record showing the package never reached the cardholder confirms their claim. Accept the chargeback, file a carrier claim, and reship if appropriate.
- Delivery to wrong address. If the tracking shows delivery to an address that doesn't match the cardholder's, this is evidence that they didn't receive it — not evidence that they did.
- Digital delivery without access logs. An email saying "your download link is ready" is not proof of delivery. You need server-side logs showing the content was actually accessed.
- Submitting the order confirmation as "proof of delivery." An order confirmation proves a purchase occurred; it says nothing about whether the goods were delivered. Never submit this as your primary delivery evidence.
- Missing the 20-day response window. Automatic loss. Track every NF chargeback notification date and respond well before the deadline.
Build a Delivery Evidence Package That Wins
Learn how to structure carrier records, digital access logs, and communication timelines into a winning NF response — and how to fight friendly fraud non-receipt claims effectively.
Get the step-by-step winning strategy →Response Framework Overview
A winning NF response is straightforward when delivery evidence is solid:
- Lead with proof of delivery. Carrier tracking screenshot showing "Delivered" to the cardholder's address, with date and time. Attach the delivery photo if available.
- Confirm address match. Show the shipping address on the order matches the cardholder's billing address or their confirmed ship-to address. Address your rebuttal directly to the specific delivery event.
- Add supporting evidence. Customer service communications, digital access logs, or any post-delivery customer contact that confirms receipt or satisfaction.
- Rebuttal narrative. One paragraph explaining the delivery timeline — when the order was placed, when it shipped, when it was delivered, and why the cardholder's non-receipt claim is inconsistent with the delivery record.
If goods were genuinely not delivered, accept the chargeback, reship or refund, and open a carrier claim for lost packages.
Prevention Tips
- Always ship with tracking. No-tracking shipments create unwinnable NF chargebacks. The incremental cost of tracked shipping is trivial compared to a single lost chargeback.
- Use signature confirmation for high-value orders. For orders above a threshold (e.g., $100+), require signature confirmation at delivery. This provides irrefutable proof of receipt and deters friendly fraud claims.
- Send proactive shipping and delivery notifications. Email and SMS updates at each tracking milestone keep customers informed and reduce disputes from anxious buyers who lose faith in delivery.
- Log all digital deliveries server-side. Record every download initiation, license key activation, and account access event in your server logs. This is your proof of delivery for digital goods.
- Set realistic delivery expectations at checkout. Display expected delivery dates clearly. When delivery expectations are met, non-receipt disputes drop significantly.
- Proactively address delays. If a shipment is delayed past the expected date, email the customer with an updated ETA before they dispute. Proactive communication prevents most legitimate NF disputes.
- Validate shipping addresses at checkout. Catch typos and invalid addresses before fulfillment, reducing delivery failures caused by bad addresses.
