We're drowning in SEO-spam spec sheets and AI-generated product descriptions. But hidden in plain sight on every box is a system of identifiers that can cut through the noise — if you know which one to trust. This episode maps the full taxonomy of product codes: UPC, EAN, GTIN, MPN, ASIN, SKU. We explain where each comes from, what it actually identifies, and why the manufacturer part number is the only one that points to real engineering data. Then we walk through the practical spec-hunting playbook: how to find the MPN on a box, how to use it across retailers and regions, and why the same vacuum cleaner has different barcodes in Chicago, Berlin, and Tokyo.
