Bar codes can take different forms. Each form is called a symbology and is designed for a particular
purpose. The equipment used to print or read bar codes must have the correct software for the EAN
symbology being used. Most organizations which use the EAN system to keep track of items use the
numbering and bar code system together with scanning devices, appropriate software, and a computer.
The size and the light margins at each end of the bar code are the components of a bar code. The
Interleaved Two of Five (ITF) methodology of bar code symbols is suitable for lower quality of
packaging materials which are used for trade items. The ITF symbol is used in the shipping and
warehousing industry and can be read by fixed and portable bi-directional scanners.

When you are in an online store and if you like a product and want to add it in a
wish list for future purchases, then you can just open the shop application and add
it to a shopping list. The barcode of the item is stored in the shopping list.
5.2.5 EAN Location Numbers
We know that the EAN system works by identifying each item with a code comprising of two main
parts, a number and a barcode symbol. The number uniquely identifies the item and is encoded into a
bar code symbol which is placed on the item with the corresponding number underneath. Light and
dark parallel bars of differing widths form the bar code symbol and allow electronic reading by a wide
range of scanning devices.

Did you know? The EAN location number is recognized by the United Nations working party
responsible for UN/EDIFACT and by the International Standards Organization.

EAN location numbers identify any location within an organization. This includes companies, their
subsidiaries and divisions, and departments. Each location is allocated a unique 13-digit identification
number with 3-digit prefix. The last digit is the check-digit which is calculated based on the first 12
digits and provides security from wrong data capture.
The table 5.3 shows an example of EAN location number 3451523457896.
