Converting a UPC-E barcode to UPC-A barcode

UPC (Universal Product Code) is a numeric symbology used in retail applications. UPC has two variations, an 11 digit UPC Type A barcode and 6 digit UPC Type E barcode. A check digit is automatically calculated by the barcode generation software in both UPC variations for a total of 12 digits on a UPC-A barcode and 8 digits on a UPC-E barcode. There are scenarios where it is necessary to receive a UPC-A barcode.
