The BAS State Certification program provides the opportunity for state level agencies to verify that the status and boundary updates received through the annual BAS were accomplished according to state law. The Census Bureau asks the Governor of each state to designate a State Certifying Official to review listings of annexations received by the Census Bureau through the annual Boundary and Annexation Survey. The Census Bureau mails a data package containing a DVD with a listing of annexations reported through the BAS for the previous BAS cycle, DVD(s) containing PDF maps of all entities that reported boundary changes during the previous BAS cycle and a State Certification Respondent Guide to guide the State Certifying Official through the process of reviewing the annexations. Please contact the Legal Areas Team of the Census Bureau's Geography Division by phone at 301-763-1099 or by e-mail at firstname.lastname@example.org for inquiries about your state's BAS contact and the State Certifying Official (SCO).
