The U.S. Census Bureau seeks public comment on the Local Update of Census Addresses (LUCA) operation by April 20, 2026.
According to the Federal Register Notice, LUCA is a voluntary “opportunity provided by the U.S. Census Bureau to enable tribal, state, and general-purpose local governments to review and comment on the Census Address List for their respective jurisdictions prior to the decennial census. The Census Address List Improvement Act of 1994 (Pub. L. 103-430), codified at 13 U.S.C. 16, expanded the Census Bureau’s authority to share selected address information with tribal, state, and general-purpose local governments for the purpose of improving the residential address list. The LUCA operation … focuses on the review and submission of residential address information, including individual housing units, group quarters, and transitory locations, in support of a complete and accurate census count.”
Who can participate: “legally defined federally recognized Native American and Alaska Native areas (including the Alaska Native Regional Corporations), states, governmentally active counties, and equivalent entities, incorporated places, and legally defined minor civil divisions (MCDs) for which the Census Bureau reports data.”
LUCA will occur October 2027 through March 2028. [The Bureau had to publish a correction on February 27 to the dates originally listed.]
“The Census Bureau has introduced multiple new tools to assist participants with conducting their work, such as an address matching service, web-based tools that eliminate the need for the download of software, and a secure portal to facilitate communication and registration. There will be no paper materials for 2030 LUCA.”
