Boundary and Annexation Survey (BAS) Forms

The BAS Forms are created for the following geographic entities: counties or county equivalents, minor civil divisions (MCDs), places, consolidated cities, and American Indian areas/Alaska Native areas (AIAs). These forms are for reference only and do not need to be returned. The forms include contact information for the Highest Elected Official(HEO), Tribal Chair(TC), and BAS contact. Only the 2014 BAS annexations are included on these 2015 BAS forms. For annexations for all years, see Annexation Data. County forms also include functional status of governments within your county

If you have updates to this data please review the Respondent Guides.

If you have updates to the contact data (HEO/BAS/TC), please use our online Annual Response Form.

The naming convention for all entities is:   <Entity Name>_<BAS Code>_BAS<yy>AR.pdf where <yy> is the last 2 digits of the year.

For a complete list of BAS Codes, please see our BAS Codes page.
