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 a message via the form at http://www.questionpro.com/help. We may incorporate/import that data and make it available as part of our standard databases.

What about other databases — Like a list of all High Schools in the US, or a list of all Universities?

These are custom databases that are not available in the public domain. They have to be acquired by purchasing custom data licenses from various data providers.
