Startup Idea: Address Validation Software for Insurance Sector

Startup idea to develop a continuously updated software program that validates and corrects physical address entries for the insurance field. The application would show a list of current valid addresses, incorporating new addresses as they are added to the postal system.

I work in the insurance field. Currently, I have to manually correct physical address locations into a database.

If there was a software that would show us a listing of current valid addresses to choose the correct address. The biggest problem I see is that there are constantly addresses added to the postal system.

So far, I've never found a software program that can keep up with the changes and be useful for this type of entry validation.
