I did a postcode lookup using the Google maps API to return the full address if that's what you are after?

// Client Script : Postcode REST Call - House Number (String inputs from "house" and "postcode" fields)

function onChange(control, oldValue, newValue, isLoading) {
     if (isLoading || newValue == '') {
     return;
   }
     var house = newValue;
     var postcodeInput = g_form.getValue('postcode');

     var ga = new GlideAjax('REST_API_CALL');
     ga.addParam('sysparm_name','getData');
     ga.addParam('sysparm_house',house);
     ga.addParam('sysparm_postcodeInput', postcodeInput);
     ga.getXML(responseParse);

     function responseParse(response) {
     var answer = response.responseXML.documentElement.getAttribute("answer");
     var stringifiedAnswer = answer.toString();
     var addressArray = stringifiedAnswer.split(", ");

     //g_form.setValue('full_address', answer);
     if(addressArray.length==7){
   g_form.setValue('address_line_1', addressArray[0] + ", " + addressArray[1]);
   g_form.setValue('address_line_2', addressArray[2]);
   g_form.setValue('town', addressArray[3]);
   g_form.setValue('region', addressArray[5]);
   g_form.setValue('country', addressArray[6]);
   }
     else if(addressArray.length==6){
   g_form.setValue('address_line_1', addressArray[0] + ", " + addressArray[1]);
   g_form.setValue('address_line_2', addressArray[2]);
   g_form.setValue('town', addressArray[4]);
   g_form.setValue('region', addressArray[3]);
   g_form.setValue('country', addressArray[5]);
   }
     else{
   g_form.addErrorMessage("Error occurred!, please check the details given. If the error reoccurs please enter the address manually.");
   }
   }
}
