What is a UPC (or EAN) for a music release?
A UPC is the barcode that identifies a whole release, such as a single, EP or album, as one product; the number it carries is a 12-digit GTIN, and an EAN is the 13-digit version. Here is how the number is built, what GS1 charges, and why most independent artists take the free one from their distributor.
