Chapter 6 • Using UPC Bar Codes

UPC Specifications

UPC symbols are found on almost all grocery products

and many other retail items. The UPC code most peo-

ple 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.

Each digit is constructed of two bars and two spaces.

UPC has very precise standards of code size, structure,

and numbers to be used.

The exact UPC symbol specifications are available from:

GS1 US (formerly Uniform Code Council)

7887 Washington Village Drive, Suite 300

Dayton, OH 45459

937-435-3870

Specifications are also available via the internet at:

http://www.gs1us.org

Keep the following guidelines in mind when printing UPC bar codes:

• Make it an early practice to observe the numbering conventions of

the GS1 US. 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:

0,6,7,8 Regular UPC 12 digit codes with numbers assigned by the

GS1 US (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.
