1. The Short Answer: Which Barcode Do You Need?
If you are selling products in the United States or Canada, the standard retail barcode is UPC-A (12 numeric digits). If you are selling products anywhere else in the world (Europe, Asia, Latin America, Australia, Africa) or globally, the international standard is EAN-13 (13 numeric digits).
Modern point-of-sale scanner hardware and software globally can read both UPC-A and EAN-13 interchangeably. In fact, a 12-digit UPC-A is mathematically identical to an EAN-13 with a leading zero (0 + UPC-A = EAN-13).

๐ Amazon Product Barcode Requirements
When creating a new product listing on Amazon, Amazon requires a valid Product ID (GTIN). You can provide either a 12-digit UPC or a 13-digit EAN. Amazon validates your barcode against the official GS1 GEPIR database to confirm that your company name matches the GS1 prefix license holder.
