BAS ID: ,
The U.S. Census Bureau received your response to the Boundary and Annexation Survey (BAS) indicating
that your government has boundary changes to report.
Action Steps:
•

Submit boundary changes to the Census Bureau. On the BAS website, you will find detailed
information on how to report updates to the BAS digitally or using paper maps. There you will
find respondent guidelines, the Geographic Update Partnership Software (GUPS), the BAS
partnership tools, partnership shapefiles, paper maps, previous annexation data, and other
important documentation.
NOTE: Please respond to the BAS with a “No Changes” response if, after reviewing your
government’s boundaries, you determine there are no boundary changes to report. If you do
not respond, we will contact your government to confirm your boundary change status.

•

Obtain a Secure Web Incoming Module (SWIM) registration token. All governments responding
digitally must use the SWIM. This token will be provided in a separate email. Paper participants
or those with an existing SWIM account will not receive a registration token.
