What Discover Reason Code UA10 Means
Discover reason code UA10, Request for Copy Illegible or Not Received, is Discover’s retrieval request code. It is filed when Discover or the issuing bank requested transaction documentation and either the merchant did not respond or the response was unreadable.
UA10 is typically a precursor to the actual substantive dispute. Failing to respond adequately forfeits the merchant’s right to contest the underlying chargeback that follows.
UA10 is a retrieval request failure — the underlying dispute has not yet been fully adjudicated. Respond promptly with legible records to preserve your right to contest the actual chargeback. An unanswered UA10 often becomes an automatic loss when the underlying dispute is filed.

Common Trigger Scenarios
- No response to retrieval request. Discover sent a request for transaction documentation and the merchant or their processor did not respond before the deadline.
- Illegible documentation submitted. The merchant responded but the documents were blurry, cut off, or otherwise unreadable by Discover’s review team.
- Incomplete response. The merchant responded but did not include all requested documents — missing a signature page, itemized receipt, or authorization record.
- Wrong document submitted. The merchant submitted documentation for a different transaction, customer, or date than the one requested.
- Response received after deadline. The merchant submitted documentation after the retrieval response window had closed.
Key Deadlines & Timeframes
| Milestone | Timeframe | Notes |
|---|---|---|
| Retrieval Request Deadline | Varies | Check your processor’s notification for the specific deadline; typically 20–30 days |
| Merchant Response Window | 30 days | From dispute notification; respond as early as possible |
| Pre-Arbitration | 30 days | If Discover rejects representment |
Evidence You Will Need
- Legible transaction receipt — original signed or electronic receipt clearly showing date, amount, last four card digits, and merchant name
- Authorization record — electronic authorization confirmation including approval code and timestamp
- Invoice or order details — itemized documentation of what was purchased, including descriptions, quantities, and prices
- Cardholder agreement — if the transaction involved a subscription or recurring agreement, the signed agreement
- Delivery confirmation — for physical goods, carrier tracking confirming delivery

- Missing the retrieval deadline. Retrieval requests have hard deadlines. Missing them forfeits your right to contest the underlying chargeback in most cases.
- Submitting blurry or cut-off documents. Illegible documents are treated the same as no documents. Scan at high resolution and confirm readability before submitting.
- Incomplete response. If Discover requests a receipt, authorization, and invoice, submitting only the receipt is insufficient.
- Poor record retention. If documents were purged or disorganized, you have no ability to respond adequately to retrieval requests.

- Respond immediately, not at the deadline. Pull the requested documents as soon as the retrieval request arrives.
- Verify legibility before submitting. Rescan at higher resolution if any document is blurry or cut off.
- Include all requested documents. Match each item in the request to a specific document in your response.
- Retain proof of submission with a timestamped record showing when you submitted the response.
Prevention Tips
- Retain transaction records for at least 18 months. Retrieval requests can arrive well after the original transaction. Purged records cannot be produced.
- Store documents in retrievable formats. Digital records organized by transaction date and last four card digits allow instant retrieval when a copy request arrives.
- Designate a retrieval request owner. Requests that fall through the cracks become automatic losses. Assign a specific person or team to monitor and respond.
- Scan receipts at time of transaction. High-resolution scans taken at the point of sale ensure legible records are always available, even if physical receipts fade.
Frequently Asked Questions
Is UA10 the same as the underlying chargeback?
No. UA10 is a retrieval request — Discover is asking for documentation before the actual dispute is filed. Responding adequately preserves your right to contest whatever chargeback follows.
What happens if I miss the UA10 response deadline?
You lose the right to present evidence on the underlying chargeback. The dispute that follows will be processed as a loss without the ability to contest it.
How clear do my documents need to be for a UA10 response?
All text, numbers, and signatures must be fully legible. Scan at 300 DPI minimum. All four corners of each document must be visible.
