UPC/ serial code questions?

ok let me get this straight.. UPC numbers are used to identify a product, so if i buy two of the exact same product, they will have the same upc code. isbn is pretty much the same thing, but used for books, and issn is for magazines? and then serial numbers are different on every single product to help with loss prevention and for registering a product… is that right? are there any other codes?

    i guess lot or batch numbers… I believe they use that for perishables and medications? In case they do recalls, and stuff, I think it is easier for them to find the batch that are bad that way?
    And for magazines, some have the same number (is that issn?) but can be different — like march issue is different from April issue but the same issn numbers…
