UPC-A Barcode Format
Universal Product Code UPC-A barcodes contain a strip of scannable bars and a 12 digit numerical code. Numbers may only be used for this code, UPC-A barcodes do not include letters or other characters. They are widely used in supermarkets and on books and other periodicals.
In the United States, new UPC codes must be requested from the nonprofit group GS1.
In UPC-A codes:
- The first number details the UPC’s number system;
- The following five numbers are the manufacturing code;
- Five more numbers serve as the product code; and
- A single number at the end of the sequence serves as the check digit.
- The check digit is used to ensure that the barcode has been read correctly.
UPC-A is somewhat similar to the EAN-13 code system, and UPC-A code can be read by any machine that can read EAN-13. The bars in UPC and EAN codes often appear similar and follow similar patterns. The only difference is where the readable digits are located. UPC code has been widely used since 1974 and cannot be translated into EAN code.
