UPC E version

• Zero Suppression
  when displaying the symbols on the small product which cannot display A version within, like the short version of JAN, removing zeros in the code by the rule of Zero Suppression Method, and shorten 12 digits to 8 digits.

  The rule is as follows:

  In case original code is 0 - ABCDE - VWXYZ,

  1. VWXY are zero
     

     0 - ABCDE - 0000Z = ABCDEZ
     * but Z can take only within 5 -- 9.

  2. E and VWXY are zero
     

     0 - ABCD0 - 0000Z = ABCDZ4
     * the last "4" indicates that A and D in the maker code is non-zero.

  3. DE and VWX are zero
     

     0 - ABC00 - 000YZ = ABCYZ3
     * the last "3" indicates that A and C is non-zero, and that ABC is a three-digit number.

  4. DE and VW are zero, C is 0, 1 or 2
     

     0 - AB000 - 00XYZ = ABXYZ0
     0 - AB100 - 00XYZ = ABXYZ1
     0 - AB200 - 00XYZ = ABXYZ2
     

  NS is fixed to zero, and doesn't exist in the data of barcode. the number (for displaying) is only shown in the leftest of the barcode.

  Checkdigit is calculated not from this 6-digit, from the original checkdigit (before zero suppression), and displayed on the rightest of the barcode.

  There is no character for displaying checkdigit.
  As same as creating the prefix of EAN symbols, it is expressed with the combination of odd/ even parities of 6-digit characters.

  

• LAC (Local Assing Code )
  A variant of instore marking, using 5-digit, zero-headed (but last 4 digits must be within 1000 - 7999) maker codes, and 1-digit item code.

• RZSC (Retailer Zero Suppression Code)
  The private code which uses the Zero Suppression.

UPC add-on version

Supplementary code is used for indicating the price of products, issue month of magazine, etc.

• Character pattern of the supplementary code
  In the supplementary code, there are 20 characters of E version odd/ even parity; 1 module bar, called delineator is inserted between each of these characters. There is no start/stop characters.

• Checkdigit of the supplementary code
  The combinations of 2-digit supplementary codes, from 00 to 99, are determined with odd/ even parities, and this combination takes place of its checkdigit.
  The checkdigit for the 5-digit supplementary code is the bottom 1 digit of modulus 10 sum, and expressed with the corresponding combination of odd/even parities.
