Address validation is not 100% reliable, so systems should have an override "Yes, this is my address" option. Unfortunately many forms assume address validation is foolproof, so there is no mechanism for entering in your actual address. It just gets rejected.

As a customer, I wanted to buy something and the website wouldn't accept my address (since it wouldn't accept any "/" characters). Guess what? There are plenty of addresses in the US with "/", such as 50 1/2 Foobar Street. Address validation does not always work, so companies shouldn't act that way.
