State-zip-code-GeoJSON

Zip code boundaries for each of the 50 states

This is a collection of zip code boundrary files for each of the 50 states, plus DC. Thanks to Github user jgoodall for his us-maps example! His example was how I found where to download the shape files.

Each file from the Census is of the format:

tl_2010_STATE_FIPS_CODE_zcta510.zip

Where STATE_FIPS_CODE is the two-digit [Federal Information Processing Standard state code] (https://en.wikipedia.org/wiki/Federal_Information_Processing_Standard_state_code).

Each file was then unzipped, converted to GeoJSON with ogr2ogr, and minified with json-minify. Here's an example for Delaware:

Zip codes

Then unzip the files, and run:

ogr2ogr -f "GeoJSON" de_delaware_zip_codes_geo.json tl_2010_10_zcta510.shp

json-minify de_delaware_zip_codes_geo.json > de_delaware_zip_codes_geo.min.json
