World zip code database free download
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 , we originally pulled down all the US census data we could find, parsed it and exported it into 3. Later, we wrote 3 rake tasks to automate this process.
In 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. In we refactored the project and made it into a Ruby gem with a command-line executable for automating this process. The Census assigns an area to a ZCTA according to census blocks the smallest geographic unit used by the census.
Imagine a city block that makes up a typical census block as pictured to the right. It is bounded on all 4 sides by portions of city streets that each have their own name and addresses. The issue is that census blocks almost always split down the middle of the street.
ZIP codes rarely do because that would require two postal workers delivering mail to that street - one for each side of the street. In the example, one mail carrier may deliver to 3 sides of the block via one ZIP code while another mail carrier delivers mail on the other street in a different ZIP code.
When this happens, the Census Bureau will assign the entire block to a single ZCTA in this case, because the census block is the area that is precisely measured. If you are getting very precise usually a matter of meters, not miles , census block boundaries near the edge of a ZIP code almost always split ZIP codes. The statistics provided by the Census Bureau can give insight into the demographics within the ZIP code.
For instance, see our ZIP code rankings. Remember that ZIP codes were made to make mail delivery easier.
