For a regional listing the actual street address is where a business should be listed, not where it has a PO box. Regional listings are, for the most part, predicated on where a visitor can physically contact a company, ie where it has an office or shopfront you can walk into.
So it probably should go back to the locality it was first submitted to. <img src="/images/icons/grin.gif" alt="" />

Personal opinion
If I was looking for a company to do work I'd rather contact one that provides a physical, rather than a po box address. There is no reason IMHO not to list both.

Thank you for the information.
I have changed the contact page to include both the physical address and the mailing address.
The editor can best judge where to index the page for the directory.
Again, I appreciate the advice.
