GS1-128

Example 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, 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 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

All dates are formatted as YYMMDD.

y in the AI gives a number of decimal places.
