Record Validation automatically configures and maps your standard address fields for the Lead, Contact, and Account Object. If you want to adjust your configuration (adding more/fewer fields to your current fieldset) or add a validation for a new set of fields, access the Record Validation Setup page.
To use a different set of fields with Record Validation, you can add a Validation by clicking 'Add validation'. Street, City, State, and Country are mandatory fields for acquiring a valid validation.
Instead of showing field labels, it's also possible to show the fields' API names.
