Amazon's KYC audit (Know Your Customer) is usually only triggered on European sites, mainly to understand the legality of account fund transactions, whether the products sold in the seller's store are legal, and whether there are high-risk individuals or regions in the transaction object.

However, some sellers have recently reported that not only European sites, but also sellers on the US, Canadian and UK sites have received bank account KYC audit notifications.

This may be because Amazon has fully launched the KYC audit of the collection account, requiring same-name verification and providing Amazon with the entire complete path for the collection company to return the money.

Therefore, it can be inferred that Amazon's KYC audit has expanded to more sites.
