Hello @Seller_NVU9vhTMKuU61,

Yes, it is generally possible for two different seller accounts to sell the same brand on Amazon. There are a few key points to consider:

1. Brand Registry: If the brand is enrolled in Amazon's Brand Registry program, the brand owner has more control over who can sell their products. However, other sellers may still be able to sell the brand's products, especially if they are authorized resellers.
2. Resellers vs. Authorized Sellers: Resellers who purchase products from authorized distributors or directly from the brand owner can generally sell the brand's products, even if they are not the brand's official seller on Amazon. Authorized sellers are those directly approved by the brand.

Let me know if you need any clarification or have additional questions!
