1. UPC-A Barcode Introduction
UPC-A is also known as Universal
Product Code version A, UPC-A Supplement 5/Five-digit Add-On, UPC-A Supplement
2/Two-digit Add-On, UPC-A+5, UPC-A+2, UPC Code, UPC Symbol, GTIN-12, GS1-12, UCC-12
The "UPC-A bar code" is by far the most common and well-known symbology, at least in the United States. An UPC-A bar code is the bar code you will find on virtually every consumer good on the shelves of your local supermarket, as well as books, magazines, and newspapers. It is commonly called simply a "UPC bar code" or "UPC Symbol." This isn't entirely accurate since there are a number of other UPC formats (UPC-E, UPC 2-Digit Supplement, UPC 5-Digit Supplement).
