Reference Data question

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.

What about zip/postal codes from other countries?

Most countries do NOT make their Zip/Postal codes available free of charge. For example, in order to import the UK Postal Database, we would have to pay the Royal Postal Service over 20,000 USD. If you are from a country that HAS OFFICIALLY made the postal code/zip code database publicly available, please send us the URL/Site. We may incorporate/import that data and make it available as part of our standard databases.
