UPC (Universal Product Code / Barcode) Definition
What UPC Codes Are, How They Work & How to Get Them
UPC stands for Universal Product Code, the barcode system used for retail products in North America.
The Universal Product Code was the first system of barcode labelling to be widely adopted. According to BarCode 1, the American grocery industry first established UPC as the standard barcode symbology for product marking April 3, 1973, and foreign interest in UPC led to the adoption of the EAN code format, (a format similar to UPC), in December 1976.
A 50 stick package of Juicy Fruit chewing gum was the first product to have a barcode scanned in a retail store, on June 26, 1974 at Marsh's supermarket in Troy, Ohio . (For the curious, it was a 67 cent sale. You can see this package of gum on display at the Smithsonian Institution's National Museum of American History in Washington, D.C.)
The standard Universal Product Code version is known as UPC-A and is 12 digits long. There is also a shortened 8 digit version called UPC-E which can be used when there is not enough room for the 12 digit version. Europe uses a different barcode system called the EAN (European Article Number) which is either 8 or 13 digits long.
To ensure global conformity of the EAN/UCC numbering system (and make trade between countries easier), as of January 1, 2005 the Sunrise 2005 initiative mandated that "all U.S. and Canadian companies must be capable of scanning and processing EAN-8 and EAN-13 symbols, in addition to 12 digit UPC symbols, at point of sale" (ECCC).
The Many Uses of Barcodes
Barcoding is an integral part of point-of-sale (POS) systems. When a barcoded product is purchased and scanned at checkout pricing and product information is automatically retrieved by the POS system. Retailers collect enormous amounts of information from POS systems on a daily basis - this is processed and used for planning and marketing purposes.
But it's not just retailers who use barcodes. Barcodes are also used in manufacturing (as in the automobile industry, for instance), for data tracking and for security. For example, in some hospitals, barcoded tags are used to identify patients.
Do I Need a UPC Code?
Businesses that offer products for sale using a brand name/label that belongs to them and businesses that trade outside of Canada need to have UPC barcodes. UPC bar codes are also handy for scanning and tracking your products through the supply chain.
How Do I Get a UPC Code?
Organizations that wish to use a UPC code must apply to GS1, which is a non-profit organization that maintains global standards for the identification of goods, and deals with bar code issuance and maintenance. Having a single organization issue UPC codes ensures that no two products can have the same UPC code.
If you need a UPC, you need to apply to GS1 for membership and a company prefix. (The link will take you to the GS1 page with details about the UPC barcode application process.) A yearly fee is required to maintain a UPC Code registration with GS1.
What Is the Composition of a UPC-A (12 digit) Code?
The first digit of a UPC Code defines the numbering system:
- 0: regular UPC codes
- 1: reserved
- 2: random weight items marked at the store
- 3: National Drug Code and National Health Related Items code
- 4: no format restrictions, for in-store use on non-food items
- 5: for use on coupons
- 6: reserved
- 7: regular UPC codes
- 8: reserved
- 9: reserved
The next group of 5 digits identifies the manufacturer. This number is assigned by GS1. The next 5 digits identify the particular product and are assigned by the manufacturer. The last digit is a Modulo 10 checksum.
How Can I Look up UPC Code Information for a Company?
You can look up UPC barcode information through the GEPIR (Global Electronic Party Information Registry), which has information for GS1 registered companies worldwide. You can search for a company by UPC number or UPC information by company name.
Also Known As: Bar code.
Common Misspellings: Unaversal Product Code.
Examples: With Sunrise 2005 in effect, both EAN and UPC labels should scan properly worldwide.
