That seems like a rare case to me. Typically there's a company name or model number somewhere on the item, and often that identifier returns a very specific item.

Looking around my house, I only see a few items that don't have unique identifiers like furniture or plates/utensils. However, I suspect the majority of things sold through Amazon/eBay are more likely to be video games, books, toys, etc. with very visible and highly unique names.
