These unique files are derived from data in the quarterly USPS Vacancy Data. To provide additional avenues for merging these data, PD&R has released the HUD-USPS Crosswalk Files. While some acceptable methods of combining ZIP codes and Census geography exist, they have limitations.

There are valuable data available only at the ZIP code level that, when combined with demographic data tabulated at various Census geography levels, could open up new avenues of exploration. One of the many challenges that social science researchers and practitioners face is the difficulty of relating United States Postal Service (USPS) ZIP codes to Census Bureau geographies. The HUD-USPS ZIP Code Crosswalk files between 2012 Q Q4 use the 2010 Census geographies whereas earlier files (2010 Q1 – 2011 Q4) use the 2000 Census geographies. The HUD-USPS ZIP Code Crosswalk files are now available for 2020 Census geographies beginning with the 2023 Q1 data release. Īugust 2022 Update: The HUD-USPS ZIP Code Crosswalk API now supports a new feature to get crosswalk data for a specific state or for all states for a specific quarter. To create an account and get an access token, please visit the API page here. With this API, developers can easily access and customize crosswalk data for use in existing applications or to create new applications.
HUD’s Office of Policy Development and Research (PD&R) is pleased to announce that HUD-USPS ZIP Code Crosswalk data are now available via an application programming interface (API).
