In 2005, HUD has entered into an agreement with the United States Postal Service (USPS) to receive quarterly aggregate data on addresses identified by the USPS as having been "vacant" or "No-Stat" in the previous quarter. Under the current agreement with the USPS, HUD can make the data accessible only to governmental entities and non-profit organizations registered as users. This page allows registered users to login and access the data. If you are not a registered user, click on the “register here” link below to request access.

USPS does not provide HUD with a list of addresses or properties. Instead, HUD is provided with a tabulation of all addresses of different types and the number of addresses of each type that are vacant. HUD tabulates these counts according to the Census Tract that they fall in and distributes the data by tract as the final product.
