The Reference Data question type is used to collect or validate zip code data against “standardized” databases.
For example, if you wanted to ask users their Zip Code and wanted to validate (to make sure that the data entered is correct) against the standard US Postal Service Zip Code database you can use the Reference Data question type for this.
How to add Reference Data Question?
What are the different databases do you support?
Currently we support the following databases:
Note: You can go to settings of the question to select the database.
What if I want to use another database that is not readily available with you?
To make databases available some countries charge a huge royalty. So in case you have the access to the database and you can provide us with it, we could add it in the system.
Making the question required:
You can use the toggle button to make the question required.
WHY? When you add questions to a survey, by default, required option is turned off. When required option is not enabled, respondents can continue with the survey without selecting answers. If respondents go through all the pages in the survey without selecting answers, the response is still considered as complete. You can enable required option to make a question required so that respondents can continue with the survey only after responding to the questions.
