A UPC barcode. The Universal Product Code (UPC or UPC code) is a barcode symbology that is used worldwide for tracking trade items in stores.. The chosen symbology has bars (or spaces) of exactly 1, 2, 3, or 4 units wide each; each decimal digit to be encoded consists of two bars and two spaces chosen to have a total width of 7 units, in both an "even" and an "odd" parity form, which enables ...
The final digit of a Universal Product Code, International Article Number, Global Location Number or Global Trade Item Number is a check digit computed as follows: [3] [4]. Add the digits in the odd-numbered positions from the left (first, third, fifth, etc.—not including the check digit) together and multiply by three.
The EAN-8 code is an eight-digit barcode used usually for very small articles, such as chewing gum, where fitting a larger code onto the item would be difficult. Note: the equivalent UPC small format barcode, UPC-E, encodes a GTIN-12 with a special Company Prefix that allows for "zero suppression" of four zeros in the GTIN-12. The GS1 encoding ...
389. Montenegro. 390. Republic of Kosovo (EAN-imposed, no GS1 Member Organisation) [2] 400–440. Germany (440 code inherited from former East Germany upon reunification in 1990) 450–459. Japan (new Japanese Article Number range) 460–469.
A prefix with a first digit of "0" indicates a 12-digit UPC-A code follows. A prefix with first two digits of "45" or "49" indicates a Japanese Article Number (JAN) follows. The less commonly used 8-digit EAN-8 barcode was introduced for use on small packages, where EAN-13 would be too large. 2-digit EAN-2 and 5-digit EAN-5 are supplemental ...
The Code 39 specification defines 43 characters, consisting of uppercase letters (A through Z), numeric digits (0 through 9) and a number of special characters (-, ., $, /, +, %, and space). An additional character (denoted '*') is used for both start and stop delimiters. Each character is composed of nine elements: five bars and four spaces.
In 1974, the Uniform Code Council (UCC) was founded to administer the standard. [1] On 26 June 1974, a pack of Wrigley's chewing gum became the first ever product with a barcode to be scanned in a shop. [1] [3] In 1976, the original 12-digit code was expanded to 13 digits, which allowed the identification system to be used outside the U.S.
EAN-8. An EAN-8 is an EAN/UPC symbology barcode and is derived from the longer International Article Number (EAN-13) code. [1] It was introduced for use on small packages where an EAN-13 barcode would be too large; for example on cigarettes, pencils, and chewing gum packets. It is encoded identically to the 12 digits of the UPC-A barcode ...
