How do you stop Excel from suppressing the leading zeros in a cell used for
a
barcode that is created using a cell that has them?

More details needed. How are you putting these values into cells? By typing
them into cells formatted numerically with leading zeros? If so, are you
then applying a barcode font to such cells? If so, then it's a mystery, but
if there are other steps between entry of values and representation as bar
codes, you need to specify those steps.
