GS1-128
GS1-128 is an application standard of the GS1 implementation using the Code 128 barcode specification. The former correct name was UCC/EAN-128. Other no longer used names have included UCC-128 and EAN-128. GS1-128 uses a series of Application Identifiers to include additional data such as best before dates, batch numbers, quantities, weights and many other attributes needed by the user.
Overview
The GS1-128 standard is an application standard within the Code 128 barcode. It identifies data with Application Identifiers (AI). Without spaces below, a simple SSCC (Serial Shipping Container Code) barcode would look something like this:
[FNC1] 00 12345678 0000000001
In the example above, [FNC1] is the single character Function Code 1, which specifies that a Code 128 barcode is a GS1-128 code. 00 is the serial shipping container code ("SSCC") AI that designates the following data as a serial shipping container code. 12345678 is the company number. 0000000001 is the container number.
It is possible to encode several pieces of data in one barcode. For example a product serial number (application identifier code 21), production date (code 11), and expiration date (code 17) together would look something like this:
[FNC1] 21 12345 [FNC1] 11 090101 17 100101
An additional FNC1 is required before the production date, because the preceding product serial number is variable length. This is not required before the expiration date, because the production date is fixed length. Reordering the components to place a variable-length field last produces a more compact form:
[FNC1] 11 090101 17 100101 21 12345
Mapping to EPC codes
As EPC and EAN respectively UCC as code systems are not congruent, GS1-128 gets mapped to EPC-GTIN with a reference list including both codes per type of product. However, there is no mapping for the serial number with EPC-SGTIN.
Full list of Application Identifiers
This list is from 2003 and therefor out of date and possibly incorrect. Also this is copyrighted by GS1 – for the up to date list please see the link below for the GS1 General Specifications[1] Because code 128 is more efficient at coding pairs of digits, preference is given to even lengths in numeric fields.
All dates are formatted as YYMMDD.
y in the AI gives a number of decimal places in the following value. The represented value is the following integer divided by 10y. For example, a net weight of 22.7 kg could be coded as 3101 000227, 3102 002270, 3103 022700, or 3104 227000.
