Makes dealing with U.S. ZIP codes painless.

zipcodeR is an R package that makes working with ZIP codes in R easier. It provides data on all U.S. ZIP codes using multiple open data sources, making it easier for social science researchers and data scientists to work with ZIP code-level data in data science projects using R.

The latest update to zipcodeR includes new functions for searching ZIP codes at various geographic levels & geocoding.

Installation

You can install the released version of zipcodeR from CRAN with:

install.packages("zipcodeR")

And the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("gavinrozzi/zipcodeR")

Despite the widespread use of ZIP codes, there are challenges in using them for geospatial analysis in the social sciences. This paper presents zipcodeR, an R package that facilitates analysis of ZIP code-level data by providing an offline database of ZIP codes and functions for geocoding, normalizing and retrieving data about ZIP codes and relating them to other geographies in R without depending on any external services.}
