What evidence should you prepare for an Amazon authenticity complaint?
Read the exact performance notification first, isolate every affected ASIN and requested document, and build an evidence pack around original supplier invoices. Amazon uses invoices to verify legitimate sourcing and requires the documents to be authentic and unaltered.
Do not submit a retail receipt, order confirmation, packing slip, bill of lading, pro forma invoice, self-created document, or a redacted file that removes information Amazon asked to verify. If the notification requests another document or a different date range, follow the case-specific instruction rather than a generic template.
Create the invoice-to-ASIN evidence map
- Record performance-notification ID, marketplace, ASIN, seller SKU, supplier, purchase date, invoice number, quantity purchased, units sold, units on hand, and affected order dates.
- Match the purchasing party name and address on each invoice to the legal entity or account information Amazon expects to review.
- Confirm supplier legal name, address, contact details, website where relevant, invoice date, item description, model, UPC or other identifiers, quantity, and payment terms.
- Link invoice line items to the exact ASIN with a short product crosswalk when supplier descriptions differ from Amazon titles.
- Retain purchase orders, payments, shipping records, authorization letters, lot or serial records, and receiving inspections as supporting—not replacement—evidence.
Verify the supplier and document quality
Contact the supplier using independently verified details and confirm that the business can validate the invoice if Amazon contacts it. Check that the supplier is the manufacturer or an authorized distributor where required, and that the quantity and purchase timing reasonably support the ASIN's sales history.
Submit clear scans or original digital files in Amazon's accepted format and size. Do not change totals, dates, names, quantities, logos, metadata, or contact details. If a translation is needed, preserve the original and follow the current submission instructions.
Write a focused response and prevention plan
- Answer the notification's questions in the same order and identify each attachment by file name.
- State the verified sourcing chain and explain the invoice-to-ASIN mapping without unsupported claims.
- Describe the root cause only when evidence supports it—for example, supplier-document mismatch, catalog mapping error, warehouse mixing, or an invalid complaint.
- List completed controls such as approved-supplier review, invoice retention, unit inspection, lot tracking, and SKU segregation.
- Submit through the existing performance-notification or appeal workflow and track every response in one case record.
Know when not to submit
Stop when the invoice is unverifiable, altered, outside the requested period, issued to a different entity without a documented relationship, from an unsupported retail source, or unable to cover the sold quantity. Ask the supplier for a legitimate corrected document only if it reflects the original transaction; never manufacture evidence.
Review the current [Amazon invoice requirements for appealing a policy violation](https://sellercentral.amazon.com/help/hub/reference/external/GDQ9K277NYP6WNEW) and the exact performance notification immediately before submission. Document rules and appeal fields can change by marketplace and violation.
