    Hi Brian Edward Bollard

    I hope you are doing well.

    Thank you for the suggestion, for the verification are you looking on real time or post submission verification ( and return an error if wrong address is entered ).

    I ask because Forminator does have some hooks you may use

    add_filter( 'forminator_custom_form_submit_errors', 'my_custom_form_validation', 10, 3 );

    The parameters are $submit_errors, $form_id, $field_data_array and return the $submit_errors,

    If you need a customisation you can reach to our on demand development service https://vvpmudew.com/expert-services/, but rest assured that I forwarded your request to our product team.

    Best Regards
    Patrick Freitas
