... we have not had a problem with returns from these previously "invalid" addresses.
Different experience here. Last month, I used the override in Endicia, after pulling up the address in Google Maps. It was a main street in a mid-sized town, and Street View showed the building.
We mailed the package, it was returned with a USPS "undeliverable as addressed" sticker, then got yelled at by the customer who stated, "UPS never has a problem... why ship with the post office anyway? It's your fault, <<blah, blah, blah>>..."
Now, we always contact the customer on the phone if the address doesn't verify. Soemtimes they say, "yea, we expected your call... ship it and it'll arrive fine" (which it does). Other times, they'll say, "oh, you can't use USPS... we don't have a mailbox."
It's always best to check before you spend $5+ on postage.
