I have an address which I know is correct. Your system says it isn't a valid address. Is there any way to add it to your address database?
Our database is essentially the the US Postal Service's database. They do a pretty good job keeping their address database up to date, especially with the vast number of addresses they handle. However, they do make mistakes, and those mistakes trickle down to anyone who uses their data. In order to handle address discrepancies, they have a specialized group that you can contact to submit addresses.
Anyone can submit an address to the Address Management System for correction.
