The leading Number System Character, (the first number of the 11 digits to be
entered) should conform to these UPC assignments:
0,6,7 Regular UPC 12 digit codes with numbers assigned by the UPC
Council. (Do not use 0 as the leading number for in-store marking).
2 Store-marked random weight items of meat and produce.
3 Reserved for National Drug Code and Health Related Items.
4 Use this leading digit for in-store marking of non-food items.
5 Reserved for coupons. Do not use this today, or you will not be able
to process coupons through your system tomorrow.
UPC 2 and 5-character supplemental codes
The UPC standards include the addition of a 2 or
5-character supplemental code used with
magazines and paperback books. To read the
supplements, you must first enable them using the
TriCoder Setup Menu.
NOTE: Enabling the supplements disallows the reading of UPC codes from right to
left to assure that the supplement does not get missed.
ISBN Specifications
ISBN (International Standard Book Numbering) bar codes are essentially EAN-13
with a 5 digit supplement, where the first 3 digits are the Bookland country codes
of 978 for books and 977 for periodicals. Although the bar code contains 18
characters, the ISBN format uses only 9 of them, along with a newly calculated
Mod-11 check digit. For example, a bar code containing the numbers
978055337062153495 would transmit as 0553370626 in the ISBN format. The
TriCoder has the option of transmitting in the ISBN format.
