The **Universal Product Code (UPC)**—specifically the 12-digit **UPC-A format** (also known as GTIN-12)—is the foundational retail barcode standard across the United States and Canada. First introduced in 1974 to automate supermarket checkout lanes, UPC barcodes are required by major North American retailers (Walmart, Target, Best Buy, Costco) and e-commerce platforms (Amazon.com, eBay, Shopify) to uniquely identify trade items.
A standard UPC-A barcode consists of 12 numerical digits:
**Number System Character (1st Digit)**: Identifies the product classification (`0`, `1`, `6`, `7`, `8` for standard consumer items, `2` for weight-priced meat/produce, `3` for pharmaceuticals, `5` for coupons). **Manufacturer / Company Prefix (Next 5 Digits)**: Assigned to the brand owner by GS1 US. **Item Reference Number (Next 5 Digits)**: Assigned by the manufacturer to identify the specific item/flavor/size. **Modulo-10 Check Digit (12th Final Digit)**: Calculated automatically to verify optical scan integrity. **UPC-A**: 12 digits, standard in USA & Canada. **EAN-13**: 13 digits, standard in Europe, India, and worldwide. Modern optical retail scanners read both UPC and EAN barcodes seamlessly at checkout.
