Thanks for the ideas. It seems as there is no solution yet. The formatting
suggestions do produce 00001-0000 when there are only 5 digits in a cell.
And Jim's custom format solves that, but cannot be used in a mail merge.

I wonder if there is a way to use Jim's custom formula, and then find a way
for the format to come through the merge?

I have a column with nine-digit zip codes, but there is no hyphen separating

don't want to go in and manually add all the hypens. There must be a way to
do this (Find/Replace using placeholders?) but I can't quite come up with it.
Ideas?

Thanks,
