 UCC/EAN-128
uses normal Code 128 barcodes, but formats the data in a standardized way to identify the
type of information contained in the barcode. Code 128 includes four special control codes
named FNC1 through FNC4; by convention, the FNC1 code is used to identify barcodes that
conform to the UCC/EAN-128 standard. A normal Code 128 barcode is constructed like this:
- start code
- data
- checksum
- stop code
A UCC/EAN-128 barcode is constructed like this:
- start code
- FNC1
- application identifier
- data
- checksum
- stop code
The Application Identifier is a 2, 3, or 4-digit number that identifies the type of
data which follows. A list of many of the standard Application Identifiers appears at the
end of this article. By convention, the Application Identifier is enclosed in parentheses
when printed below the barcode (the parentheses are only for visual clarity, and are not
encoded in the barcode). The FNC1 code is not represented in the readable text. For
example, Application Identifier 420 indicates that the data contains the destination
postal code, and you will often find this barcode on shipping labels. If the destination
postal code (ZIP code in the USA) is 90210 the barcode would look like this:
When this barcode is scanned, software is alerted by the FNC1 code that this is a
UCC/EAN-128 barcode and, since the Application Identifier is 420, it contains a
destination postal code. For another example consider the tracking barcode that appears on
most packages handled by freight carriers around the world. Application Identifier 00
indicates that the data contains a package serial number; this format is called the
"UCC/EAN-128 Serialized Shipping Container Symbol". This type of barcode
uniquely identifies every package currently in transit and makes global tracking systems
possible:
- start code
- FNC1
- Application Identifier (00)
- Package Type (0 = carton)
- UCC/EAN number system/numbering authority
- Manufacturer's ID code
- Package serial number
- Check character for readable text
- Check character for entire barcode
- Stop code
A single barcode may contain more that one type of information. The beginning of each
new piece of information is marked by a FNC1 character and an Application Icdentifier. For
example, let's combine a Batch Number (Application Identifier 10) and a Sell By Date
(Application Identifier 17):
- start code
- FNC1
- Application Identifier (10 = batch number)
- Batch Number
- FNC1
- Application Identifier (17 = sell by date)
- Sell By Date (YYMMDD)
- Checksum
- Stop Code
Here is an example for Batch Number 45566 with a Sell By Date of March 1, 2004:
Here is a list of Application Identifiers. New ones are added from time to time, so
this list may not be complete. The full specification is available from the
Uniform Code Council.
