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.
