Residents may register to vote in the County Clerk's office in the Washington County Courthouse during normal business hours which are Monday through Friday 8:00 a.m. to 4:30 p.m.  Residents who are conducting business with the Department of Revenue at the Potosi License Bureau, or the Department of Social Services may also register to vote at those sites while conducting business associated with those departments.
 
The County Clerk's office also holds special registration events throughout the county from time to time.  Those events are usually published in the local newspaper.
 
Voters may now register on-line through the Secretary of State's office at www.sos.mo.gov/elections/goVoteMissouri/register
