This error sometimes also shows as Error Code 5461. This solution relates to when the error code is 5461 and the error message is You may not create ASINs for this brand. Please review our ASIN Creation Policy.
Should you be getting the alternate 5461 error message where the text is – “You are using UPCs, EANs, ISBNs, ASINs, or JAN codes that do not match the products you are trying to list.” Please see the guide here.
So what does the error “You may not create ASINs for this brand. Please review our ASIN Creation Policy.” mean and how can you solve it.
In this case, it would appear that you are trying to list a product and are using an established brand name. For example, you are trying to list a pair of Nike shoes, and are entering the Brand Name as Nike. Amazons brand registry of course recognises Nike as brand. Amazon therefor want you to use the existing listing to promote price competition.
There is of course a solution to this. Under the Brand Name of your new listing enter your seller name and simply add the brand name of Nike to the product title. Should you run into an issue using your seller name, such as the error code 5665, please follow our guide here to resolve the brand name issue.
