What is a UPC Barcode?
Universal Product Code (UPC) is the most widely used barcode format in North America, identifying products in retail environments and enabling seamless commerce.
UPC-A Format
UPC-A consists of 12 digits: a single-digit number system, 5-digit manufacturer code, 5-digit product code, and a check digit. This standardized format ensures global compatibility and accurate product identification across all retail systems.
GS1 Registration Required
For legitimate retail use, you must obtain a company prefix from GS1. This ensures your codes are unique and accepted by major retailers like Amazon, Walmart, and Target. Unregistered codes may be rejected by retail systems.
