What is a UPC barcode?
U niversal P roduct C odes (also known as GTIN-12 ) appear as lines (bars) of
varying widths representing the series of numbers commonly shown below the bars.
• Usually dark ink is on white background to create high and low reflectance, which
is converted to 1’s and 0’s.
• Barcode scanners read the bars and convert them back to the 12-digit UPC
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 them with when you
signed your agreement for them to carry your product.
• In short, the UPC is a 12-digit unique code for your product represented by
scannable bars.
• The nominal size of a UPC Symbol is 1.469" wide x 1.02" high .
• The minimum recommended size is 80% of the nominal size, or 1.175" wide .
• The maximum recommended size is 200% of the nominal size or 2.938" wide .
• Width is much more important than height. The width influences the distance
between the bars and how well the laser can distinguish between them.
