Overview
 UPC-A is used for marking products
which are sold at retail in the USA. The barcode identifies the manufacturer
and specific product so point-of- sale cash register systems can automatically
look up the price.
The UPC-A Code and the assignment of manufacturer ID numbers is controlled in
the U.S.A. by the Uniform Code Council (UCC). 
Sample of a UPC-A Barcode The value to encode by UPC-A has the following structure:
-
1 digit for Number System (0: regular UPC codes, 1: reserved, 2: random weight
items marked at the store, 3: National Drug Code and National Health Related
Items code, 4: no format restrictions, for in-store use on non-food items, 5:
for use on coupons, 6: reserved, 7: regular UPC codes, 8: reserved, 9:
reserved)
-
5 digits for Manufacturer (Company) Code or prefix. This number is assigned by
the Uniform Code Council (UCC)
-
5 digits for Product Code which is assigned by the manufacturer
-
1 digit for checksum
Add-On or Supplement code
The Add-On Symbols were designed to encode information
supplementary to that in the main bar code symbol on periodicals and paperback
books. The Add-On can be composed of 2 or 5 digits only.
Sample of an UPC-A Two-Digit Add-On Barcode Light Margin Indicators - a greater than (>) and/or
less than (<) character - are intended to protected the essential light
areas to the left and right of the code that the barcode scanner needs to
recognize the beginning and end.
