County Voting Systems



Montana’s paper ballots may be counted in two ways: hand count or with paper ballot optical or digital scan tabulators.  Either way ALL Montanans vote on a paper ballot.  Following is a list of the voting systems being used, by county.

Paper ballot tabulators

Model 650 (optical scan), DS850 (digital scan), DS450 (digital scan), and DS950 (digital scan) are central count tabulators; Model 100 (optical scan) and DS200 (digital scan) are precinct-level tabulators.  Tabulators are not connected to the Internet.

Counties conduct a public test of tabulators before each primary and general election. Additionally, a random test is conducted on election day.  A Post-Election Audit is conducted by each county that uses tabulators after federal elections. The post-election audit consists of a hand-count of randomly selected contests and precincts.

See the table below to view which method of paper ballot tabulation is used in each county.
