This program is local governments’ last chance to update the Census Bureau’s address list before April 1, 2020, Census Day. This program allows local jurisdictions to submit city style mailing addresses for housing units constructed and/or completed after address canvassing and LUCA. In addition, local jurisdictions should submit lists of group quarter addresses and transitory housing locations (such as shelters, soup kitchens, official homeless housing, and regularly scheduled mobile food vans).

This program offers federally recognized tribes, state tribal liaisons, local governments, councils of government, and regional planning organizations the opportunity to review and modify select statistical boundaries that the Census Bureau uses to report the data that they collect. Registration will be March-May 2018. The work will be completed January-July 2019.
