Hyphens or spaces usually separate the elements of the number on the item. The code has three basic parts:

The first digit is the Number System Character (NSC) which appears on the left side of the symbol outside of the bars.
The next ten digits encoded in the symbol are below the bars.
The twelfth digit is a check digit and usually appears at the bottom right of the symbol.

Enter all digits found on the item (e.g., 008817006925).
