Length: 8 digits (7 digits + 1 check digit)

Special notes: Not every UPC-A code qualifies for compressing to UPC-E. If that is the case Barcode alpha software will notify you about that.
Description: UPC-E is a variation of UPC-A which allows for a more compact barcode by eliminating "extra" zeros. Since the resulting UPC-E barcode is about half the size as an UPC-A barcode, UPC-E is generally used on products with very small packaging where a full UPC-A barcode couldn't reasonably fit.
