Real example
An EAN-13 like 5901234123457 breaks down into: country/region prefix (590 = Poland), company prefix, product reference, and check digit. When you add a leading zero to a 12-digit UPC, you get a valid EAN-13 — which is why the two formats are compatible on most scanners.
How an EAN Code is used in e-commerce
- Amazon EU marketplaces (Amazon.de, Amazon.fr, Amazon.co.uk) use EAN-13 as the standard product identifier.
- European retail requires EAN-13 on product packaging.
- International shipping labels frequently use EAN-13 for customs and warehouse scanning.
- Shopify's barcode field accepts both UPC and EAN.
