NSD = Number System Digit. The NSD character is the character that precedes the
UPC bar code. The NSD for regular UPC-A bar codes is a zero. Other commonly
used Number System Digits used with UPC-A are:
2 - used for random weight items such as meat and produce
3 - used for the drug and health items
4 - used for in-store non-food items
5 - used for coupons

If UPC-E is expanded to UPC-A, the transmission of Check Digit (CD) and NSD will
be determined by the UPC-A settings on this page.
