You would need the posal bar code font on your PC...then you would need to
create a field within your the source query for your report that constructs
the data needed for the bar code font...for example, 3 of 9 requires "*" &
[somefield]
Simpler than that. Just include a textbox on the Report with the
zipcode as its control source, and use the postal bar code font.
A Google search turns up hundreds of links, if you don't have such a
font already available.
