See http://www.morovia.com/education/symbology/upc-e.asp and http://www.barcodeisland.com/upce.phtml#Example for notes on conversion of UPC-A to UPC-E.

UPC-A is a 12 digit numerical system (11 with a check). UPC-E is a compressed, 6 digit code.

Both UPC-A and E expect a string length 11 to encode (will ignore the 12th char if provided).

Quiet zone is not automatically added. However, a quiet zone, with a width of at least 9 times the x-dimension, must be present on each side of the scannable area of the UPC-A barcode. UPC-E requires 9 X-dimension units on the left side and 7 on the right. Adding this is up to the developer.
