The UPC (U

) is used for food and consumer goods in the USA and Can-
ada. It can be compared with the European EAN. The UPC is a numeric code with 12 digits
(UPC A) or with 6 digits (UPC E). The last digit is the check-digit.

The EAN (E

) is used for labelling food and consumer goods in Eu-
rope. It can be compared with the American UPC. The first two numbers indicate the country
code, the following numbers the manufacturer and the article. The EAN code is a numeric
code with 13 or 8 digits. The last two digits are always used as check-digits.

Example of EAN 13
The UPC A is compatible with EAN 13: If EAN 13 is printed with a 0 (zero) as the first digit,
this code has the same bar sequences as the UPC A code. This type of code is decoded as
a 12-digit UPC A code in the evaluation routing of the EAN 13 and UPC A. The scanner only
decodes this 12-digit codes as UPC A, if UPC A or UPC A and EAN 13 are activated. The code
is only interpreted as EAN 13 with a leading zero if EAN 13 is activated.
