The Boundary and Annexation Survey (BAS) State Certification Program provides an opportunity for state agencies to verify that the legal boundary, name, and status updates received through the annual BAS were reported in accordance with state law. The Census Bureau requests that each state governor designate a State Certifying Official (SCO) to participate in the BAS State Certification program. The SCO reviews listings of legal boundary changes and government statuses that were submitted through the previous year’s BAS cycle.

The Census Bureau will not conduct the 2024 BAS State Certification this year. For questions regarding BAS State Certification, Contact Us.
