Zipcode data is free from the various governments around the world. Yet so many organizations, reputable or not, want to charge money for it.
This project is an automated solution for retrieving and collating US and worldwide zipcode data.
In 2011, we originally pulled down all the US census data we could find, parsed it and exported it into 3 .csv files. Later, we wrote 3 rake tasks to automate this process.
In 2017 we began using GeoNames data, which is licensed under Creative Commons. We are grateful to GeoNames for sharing, and urge you to visit their site and support their work.
•An executable: free_zipcode_data - which automates the process of downloading and process the zipcode data from GeoNames. Not all countries are accounted for. Please check GeoNames to see a list of supported country zip files.
Each zipcode is correlated with estimated or zip-centroid, latitude and longitude coordinates. Where applicable, country, county/province, state and community are also correlated.
First, you need to install Ruby and Rubygems. Though that is not a difficult task, it is beyond the scope of this README. A search engine of your choice will help discover how to do this. Once you have done that:
Determine the 2-letter country codes for the countries you want to use at GeoNames, or don't specify a country to get all zipcodes for all available countries...
The executable will generate an SQLite3 database in the specified directory --work-dir but it will not generate the .csv files by default. Specify --generate-files if you want those as well.
By default the tables will be named as follows. To override the table names see the command line options above.
The zipcode data is licensed under a Creative Commons Attribution 3.0 Unported License, carried forward from GeoNames.
