Bar Codes
Because this random data can get mistaken later for an industry standard code
format, the UCC and EAN chose a symbology uniquely identified from these oth-
er bar codes. This standard is for maximum flexibility, to handle the diversity of
distribution in global markets by cost efficiency.
The UCC/EAN-128 Container Labeling specification calls for a FUNC1 to im-
mediately follow the bar code's start character. FUNC1 also follows any vari-
able-length application field. The specification also calls for the computer to send
"]C1" for the first FUNC1. The specification requires that the computer send a
"<GS>" (hex 1D) for subsequent FUNC1 codes in the bar code.
Because "<GS>" is not compatible with computer emulation data streams, the
Uniform Code Council has been asked to change the specification. This change is
made to send the same three character sequence "]C1" to identify the embedded
FUNC1 codes.
This implementation should provide for clean application coding by identifying
the same sequences for the same scanned codes. If the communication of Norand
bar code types is enabled, the Shipping Container Label codes precede with a "J".
These strings will appear on the computer display. The application may have to
allow for strings longer than 48 characters (maximum length indicated in the
specification). Actual length variance depends on the number of variable-length
data fields. Allowing for 60 characters should be sufficient. Within the Code 128
specification, the computer can link bar codes together. If this is to happen, al-
low for more characters (computer limit is 100 characters).
The Application Identifier Standard, that is part of the UCC/EAN Shipping La-
bel concept, complements, rather than replaces, other UCC/EAN standards.
Most UCC/EAN standards primarily identify products.
Several industries expressed the need to standardize more than product identifi-
cation. The UCC/EAN Code 128 Application Identifier Standard supplies this
tool. The standard adds versatility for inter-enterprise exchanges of perishabil-
ity dating, lot and batch identification, units of use measure, location codes, and
several other information attributes.
For more detailed information on Code 128 UCC/EAN Shipping Label bar code
and Application Identifier Standard, refer to the UCC/EAN-128 Application
Identifier Standard specification.

I 2 of 5 (Interleaved)

I 2 of 5 (Interleaved 2 of 5 Code) is an all-numeric symbology, widely used for
warehouse and heavy industrial applications. Its use has been particularly prev-
alent in the automobile industry. The I 2 of 5 symbology can be placed on small-
er labels than what the standard UPC symbology requires.
I 2 of 5 also provides a little more flexibility on the type of material it can print
on. Interleaved 2 of 5 Code has its name because of the way the bar code is con-
figured.
I 2 of 5 bars and spaces both carry information. The bars represent the odd
number position digits, while spaces represent the even number position digits.
The two characters are interleaved as one. Messages encoded with this symbolo-
gy have to use an even number of characters since two numeric characters al-
ways get interleaved together.
