GS1-128

GS1-128 is an application standard of the GS1

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.
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, production date, and expiration date together would look something like this:
[FNC1] 21 12345 [FNC1] 11 090101 17 100101
Note the additional FNC1 after the product serial number. Because the serial number is not of a fixed length, it is necessary to follow it with an FNC1 before the next AI. This is required for all variable-length AIs, except when they are the last one in the bar code.
Mapping to EPC
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.
y in the AI gives a number of decimal places.

Barcode
A barcode is an optical machine-readable representation of data, which shows data about the object to which it attaches. Originally barcodes represented data by varying the widths and spacings of parallel lines, and may be referred to as linear or 1 dimensional . Later they evolved into rectangles,...
