When a user enters an address that is not listed in the database, they will
still be able to enter the address details manually. Addressfinder will still
return addresses that are the closest matches to the address that has been
entered, but if the correct address is not listed the user can complete the
'Address Line 1' entry, and then move on to 'Address Line 2, Suburb, Post Code
etc'. Therefore you will not lose customers because their address is not
available for selection from the drop down menu.
