Amazon is not saying your product is fake. It is saying you have not proved where you bought it.
An inauthentic complaint is a chain-of-custody problem, not a product problem. The invoice is the appeal. It must be issued within the last 365 days, reflect your sales volume, name a verifiable supplier, be headed "Invoice" rather than receipt or pro-forma, and come as an unedited PDF or image.
Not "is this item genuine?" but "can you evidence where it came from?" That reframing matters, because sellers write appeals defending the product when Amazon wanted documents.
Retail receipts generally do not satisfy this. That is often the actual root cause, and saying so plainly — "we sourced from a retailer rather than an authorised distributor, so we could not evidence the supply chain" — is a stronger appeal than a defence of the product.
Five tools that take you from the notice to one properly prepared appeal — a Plan of Action builder that checks your wording against known rejection triggers, a 48-hour checklist, three worked examples, and a 90-day money plan. $149, one payment.

If large sums are frozen, if you are accused of counterfeiting or a safety breach, if you have been rejected more than once, or if your notice cites Section 3, get a lawyer who specialises in Amazon seller cases.
Where Amazon's own wording is quoted it is marked as such. Practitioner guidance is labelled as practitioner guidance. Where sources disagree, this says so rather than picking one.
