Как проверить и ограничить текстовое поле для проверки почтового индекса для всех стран с помощью регулярного выражения или по коду

Что я уже пробовал:

function getAddressInfoByZip(zip)
    {
        debugger
        //var zip = "500085";
        var key = "AIzaSyBFIZDRp_iKUPk71jCyUbmMTmBzdhWGj4s";

        if (zip.length != 0) {
            var addr = {};
            try {
                $.getJSON("https://maps.googleapis.com/maps/api/geocode/json?", { 'address': zip }, function (data, status) {
                    debugger
                    var results = data.results;
                    var status = data.status;
                    if(status == "ZERO_RESULTS" ||status=="OVER_QUERY_LIMIT"){
                        ValidateZipcodeBybasedonEntry(0,@Html.Raw(Json.Encode(Focus.Resources.msgValidateZipCodeforCountry)));
                        return;
                    }
                    if (status == "OK") {
                        if (results.length >= 1) {
                            for (var ii = 0; ii < results[0].address_components.length; ii++) {
