Q. How far back do the records go?

A. Records go back to at least 2006 for all counties. Some history may exist before 2006, depending on what the counties provided when records were converted to the statewide system.

Q. How often is information updated? How often will the customer get updates?

A. Information is updated by the counties as they process ballots, registrations, etc. Files are created nightly to reflect the updated and changed information and made available to customers.  A subscriber can request updates as often as they want, however, files are only generated nightly.

The Absentee Ballot Report is available for download directly from the site https://prodvoterportal.mt.gov/PurchaseVoterFile.aspx at the time it is purchased.

Q. Which report(s) include voter history?

A. The statewide voter file and the county and legislative extracts of the statewide voter file include voter history. The Absentee Ballot Report, Petition Signers Report, and late registrant reports do not include voter history.

Q. Does the voter file include information about whether or not a voter is on the absentee list?

A. Yes. The voter file includes an indicator (True/False) of whether or not a voter is absentee, in the field titled “Absentee.”

Q. Is municipal, school, and/or special election information included in the file?

A. Although most municipal, school, and special district elections’ history are included in the voter history file, in certain cases the history will not be included. The user should check with the county or with the Secretary of State’s office if the user is looking for history for a specific local election. The voter history file is included with purchase of the Statewide Voter File (and customized county and legislative district files).

Q. Why do some residential addresses just contain what appears to be township, range and section information rather than street addresses?

A. Some counties use legal descriptions for residential addresses in certain instances. These descriptions may appear in a format such as the following: 1 S 2 E 3. The descriptions are especially common in areas in which many voters reside in areas that do not have street addresses.

Since voters in the file also have a mailing address, the mailing address may be the most useful address in cases in which the township, section, and range are listed for the voter’s residence address.

The fee for a single copy of the extract of the voter file such as the statewide Absentee Ballot Report is $1,000.00.

The Absentee Ballot Report includes an indicator (True/False) of whether or not a voter is on the Absentee List, in the field titled “Absentee.”

Names will show up in the Absentee Ballot Report the day after ballots are mailed in each scenario above.
