basics of Seller Hub upload

[mobiledeal4u]

About to create my first draft listings using the excel file and can't believe there isn't a guide on each of the column headers.
I can't find the Category IDs anywhere. I don't know what UPCs are

@mobiledeal4ueBay Seller Hub has downloadable templates for each category. If you download a full XLSX Excel template it will contain multiple pages preloaded with options for each column. If yyou address the cells left-to-right, you'll see there is a dependency on earlier selections in a row(affecting which options are available).

UPC = Universal Product Code = the numbers which you should see beneath a bar code.

ISBN = International Standard Book Number = the numbers which you may find on many books, published since 1969.

MPN = Manufacturer's Product Number = the number of a particular item or part number produced by a manufacturer.
