The address fields specified for standardization are parsed into several additional fields. If you specify the Address match type in the wizard, the following fields are automatically added to the object structure and database creation script.
field_name_HouseNo
field_name_StName
field_name_StDir
field_name_StType
field_name_StPhon
where field_name is the name of the field for which you specified address matching. For example, if you specify the Address match type for the AddressLine1 field, the following fields are automatically added to the structure: AddressLine1_HouseNo, AddressLine1_StName, AddressLine1_StDir, AddressLine1_StType, and AddressLine1_StPhon.
You can add these fields manually if you do not specify a match type in the wizard.
