digit is constructed of two bars and two spaces. UPC has very precise standards
of code size, structure, and numbers to be used.

Keep the following guidelines in mind when printing UPC bar codes:
• If you plan to use a "supermarket-type" in-counter scanner to read
the codes, specify a bar code height of at least .9" for an optimal first
read rate.
• Make it an early practice to observe the numbering conventions of
the UPC Council. Do not label unmarked merchandise with a bar
code whose numbers may conflict with those already assigned. If
products with these numbers are not in your store now, they are
likely to be in the future, causing conflicts in your inventory system.
• The leading Number System Character, (the first number of the 11
digits to be entered) should conform to these UPC assignments:
UPC symbols are found on almost all grocery
products and many other retail items. The UPC
code most people are familiar with (UPC-A) is a
fixed-length (12 digits) numeric only code, with the
first digit controlled by UPC coding assignments
and the last digit a checksum. UPC-E and UPC-E1
are variations of the standard UPC-A code. Each
EAN is an international superset of UPC. EAN-13
has 13 digits, with the first two digits representing a
country code. The final digit is, as with UPC, a check
digit. EAN-8 is a shorter version on the EAN-13 code
containing seven data digits and ending again with a
checksum.
