Most sites/apps will let me override the validator, but a few won't. The most common ones that insist on using the wrong address are financial institutions that say the law requires them to have my proper physical address and therefore they go with the (incorrectly) validated version.
USPS does not do home delivery in our area, and UPS/FedEx/etc. usually figure it out given that street numbers alone uniquely identify properties in our town.
We have non-postal addresses and a lot of other mechanisms to help here. We also have contacts at the USPS and others to help fix addresses.
I’d love to have you email your mailing address to support@smarty.com with a link to this HN thread. We may be able to help fix some of this.
