he current UI for the Postal Code settings is not intuitive and may confuse users. The "Advanced Validation Rules" option can only be enabled after enabling "Postal Code Validation," but there is no clear indication that these options are linked. Additionally, there is no visibility into which validation rules apply when enabling "Postal Code Validation."

Problems Identified:

Lack of clear dependency between "Postal Code Validation" and "Advanced Validation Rules."

No information on which postal code validation rules are applied by default.

Unclear if "Postal Code Required" influences the validation settings.
