All bar code symbologies use a mathematically calculated check character - usually in the last position - to validate that a bar code has been scanned correctly. CheckMaster is a program that can calculate the proper check character for many symbologies, including UPC-A, EAN, ISBN, ISSN, SICI, GTIN SCC-14, SSCC-18, HIBC LIC Primary, and US Postal Code.
