What is a Universal Product Code?
“UPC” stands for Universal Product Codes. Universal Product bar codes appear as lines (bars) of varying widths representing the series of numbers commonly shown below the bars. This series of numbers is known as the UPC number. The Universal Product bar code contains no other information than this UPC number. In short, the UPC bar code is a 12-digit unique code for your product represented by scannable bars in a way that a bar code scanner can read. Bar code scanners, as you will know them from your favorite retailers, read the bars and convert them back to the 12-digit Universal Product Code number that they represent. This number is then looked up within the retailer’s inventory system to find the corresponding product name and price that you provided this retailer with when you signed your agreements for them to carry your product. This information is sent back to the register and it rings up the item. If the bar code did not scan properly then the cashier simply enters the UPC numb
