Don I should have been clearer and said that "zip" alone is not enough. Zip plus is a different story, but I've talked to so many banks who think "zip" (the five digit code alone) works for geocoding that my mind went right there
Anon with PO Box problems. I try to remind my staff that people are not able to operate a business out of a PO Box. It's difficult enough at a regular sized desk to fit a computer and a printer, let alone squeeze it into one of those little boxes
For CRA purposes we are required to report the "real" or "physical" address of the business or the collateral proceeds. It's not an option.
Take Don's advice and call him, but also take this advice if you can:
First, when you figure out the "fix" with Don, I'm sure he's going to suggest you go back and check your old data (anything that will be in this exam period that was geocoded prior to your fix). You only need to screw up 5% of your address field to be required to scrub 100% of your data and resubmit. IT sounds like this is even more of a problem than you are thinking, since you're probably using inappropriate mailing addresses as business addresses as well, but haven't caught them because they weren't PO Boxes. A data integrity check internally is in order!
And, before you send those files off to be geocoded, consider a scrub yourself first. We preform a few scrubs of the data prior to geocoding, including filtering out PO Boxes and sending the lenders notes to give us the right information. In my case it's a waste of staff time to fix this, but in yours, you've paid someone to find you a geocode and not provided them with the tools necessary to do so, which might prove costly in the long run!
