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 ...
For instance, encoding the ASCII character "0" can be viewed as 10011101100, where a sequence of 1's is a bar and a sequence of 0's is a space. A single 1 would be the thinnest line in the bar code. Three 1's in sequence (111) indicates a bar three times as thick as a single 1 bar.

where "n" is a narrow line (bar or space) and "W" a wide line (2.0 to 3.0 times the width of a narrow line). Decoding Interleaved 2 of 5. Every pair of digits is color-coded, showing the code and the value for each digit. Because digits are encoded by pairs, only an even number of digits can be encoded.
For instance, the UPC-A barcode for a box of tissues is "036000241457". The last digit is the check digit "7", and if the other numbers are correct then the check digit calculation must produce 7. Add the odd number digits: 0+6+0+2+1+5 = 14. Multiply the result by 3: 14 × 3 = 42. Add the even number digits: 3+0+0+4+4 = 11.
These barcodes only represent the digits 0–9, unlike some other barcode symbologies which can represent additional characters. The most commonly used EAN standard is the thirteen-digit EAN-13 , a superset of the original 12-digit Universal Product Code (UPC-A) standard developed in 1970 by George J. Laurer . [ 1 ]
