The GS1 System originated in the United States and was established in 1973 by the Uniform Product Code Council, known until recently as the Uniform Code Council, Inc. (UCC) and since 2005 as GS1 US.
The UCC originally adopted a 12-digit identification number, and the first ID numbers and barcodes in open trade were being scanned in 1974. Following the success of this U.P.C. System, the European Article Numbering Association, previously known as EAN International, but launched as GS1 in 2005, was established in 1977 to develop a compatible system for use outside North America.
The EAN System was designed as a superset of the UCC System and principally used 13-digit numbers. As a consequence of using certain barcodes and data structures, the GS1 System has expanded.
The former EAN barcode types are no generally known as GS1 barcode types.
