EAN-13 is based on the UPC-A standard. The EAN-13 number system code is just one digit longer than the
UPC-A number system code.
An EAN-13 bar code has the following physical structure:
a
Left-hand guard bars, or start sentinel, encoded as 101
b
The second character of the number system code, encoded as described in the following table
c
The five characters of the manufacturer code, encoded as described in the following table
d
Center guard pattern, encoded as 01010
e
The five characters of the product code, encoded as right-hand characters
f
A check digit, encoded as a right-hand character
g
Right-hand guard bars, or end sentinel, encoded as 101

The first character of the EAN-13 number system code (for example, the first digit of the EAN-13 value)
is encoded in the parity of the characters of the left-hand side of the symbol. The value of the first
character of EAN-13 determines the parity with which each of the characters in the left-hand side of the
bar code are encoded from the table.

UCC-128
UCC-128 provides a worldwide format and standard for exchanging common data between companies.
While other bar codes simply encode data regardless of what the data represents, UCC-128 encodes both
data and what that data represents. It has a list of Application Identifiers (AIs) to include more data such as
“best before” dates, batch numbers, quantities, weights, and many other attributes. Each AI tells the system
what kind of data follows and in what format.
UCC-128 can be expanded without making existing systems obsolete. If an AI is needed, then it can be
added to the standard. Applications using existing AIs are not affected.
A UCC-128 symbol has the following Code 128 structure:
a
A Code 128 start character (A, B, or C)
b
A Code 128 FNC1 character (character 102)
c
AI (from the AI table corresponding to data to be encoded)
