[2026 Latest] A Must-Read for Beginners! Basic Knowledge for Clearing Amazon Authenticity Investigations and How to Write a Plan of Action (POA)

For sellers on Amazon, one of the most dreaded notifications is an "Authenticity Investigation." This is a critical situation where not only is the authenticity of your products questioned, but it can also lead to account suspension or the forfeiture of sales proceeds in the worst-case scenario. However, if you master the correct knowledge and how to write a logical Plan of Action (POA), it is by no means an insurmountable wall. This article provides a thorough explanation of the specific steps to overcome an authenticity investigation based on the latest 2026 algorithms and review criteria.

1. What is an Amazon Authenticity Investigation? Two Main Reasons They Occur

An Amazon Authenticity Investigation is a review conducted by Amazon (specifically the Seller Performance team) to verify that the products being sold are genuine. These investigations primarily stem from the following two routes:

  • Reports from Buyers: Reviews or contacts to customer support stating things like "the product looks fake" or "the packaging is different from the official one."
  • Random Audits (Claims from Rights Owners): Cases where manufacturers or brand owners suspect sales through non-authorized distribution channels and file a claim with Amazon.

Recently, there has been an increase in authenticity investigations conducted as part of "Account Reviews" performed randomly on new accounts or sellers with rapidly growing sales. First, stay calm and accurately identify which ASIN is targeted and which terms (such as the BSA) may have been violated.

2. Essential for Success! Requirements for Valid Receipts and Invoices

The most powerful weapon for clearing an authenticity investigation is documentation that demonstrates "traceability," proving the legitimacy of your sourcing. Amazon has extremely strict standards for the documents it accepts.

  • Within 365 days of issuance: You must prove that the transaction is recent.
  • Supplier Information: The name, address, phone number, and website URL must be clearly stated.
  • Seller Information: Must match the name and address registered to your Amazon account.
  • Quantity: The quantity purchased must cover the number of units sold on Amazon over the past 365 days.

As of 2026, reviews of receipts from retail stores (electronics retailers or online shops) have become more stringent than before. Whenever possible, obtaining an "Invoice" issued by a wholesaler or manufacturer is the fastest route to account reinstatement.

3. Improving Approval Rates: A MECE Framework for Your Plan of Action (POA)

If documentation alone is insufficient, you will be required to submit a Plan of Action (POA). Here, it is crucial to eliminate emotional arguments and structure it logically (MECE). The following graph shows the distribution of elements emphasized during the review process.

Q. How many times can I resubmit a Plan of Action?
A. While there is no explicit limit, repeatedly submitting insufficient content carries the risk of receiving a final notice (commonly known as a "template rejection") stating "we may not respond to further emails." Aim to clear it on the first or second attempt by creating a high-quality, professional plan from the start.
Q. Is sourcing from Mercari or Yahoo! Auctions permitted?
A. As of 2026, sourcing from consumer-to-consumer (C2C) transactions is not recognized as a "legitimate sourcing route" in Amazon authenticity investigations. If these are your sources, proving the authenticity of the products is extremely difficult, making account reinstatement nearly impossible.
