Missouri voter file software for down-ballot campaigns.

Your Missouri voter data is included

Missouri's official voter file is a public record that any person may obtain from the Missouri Secretary of State, Elections Division (or your county election authority) — no candidate gate, no eligibility oath. A Sunshine-law production fee set under chapter 610; confirm the current statewide figure at order. County lists run roughly $25-50.

Because the file is public, VoterFile obtains the current official file directly from the source at onboarding and loads your county or district into your private workspace — you don't request anything, and there is never a charge for the data itself.

Prefer to obtain your own copy instead? That works exactly the same way:

• Submit a voter-list request for the base registration list under RSMo 115.157.1 to the Secretary of State, or assemble it county by county.
• The base list is released to any member of the public with no eligibility gate and no purpose oath.
• The file includes districts and vote history; plan around year-of-birth-only and no phone in the government file.

What the software does with your Missouri file

Once your file is loaded into a workspace isolated to your campaign, it is imported and normalized, de-duplicated, and geocoded to precincts and walkable geography.

Turnout and vote-timing scoring calibrate to Missouri's own election history, not California's, so the propensity numbers reflect how your state actually votes. From there you build targeted walk lists, mail lists, and turf, then export clean CSVs for the tools your campaign already uses.

• Import, normalize, and de-duplicate your uploaded file
• Geocode addresses to precincts and walkable turf
• Turnout and vote-timing scoring calibrated to Missouri
• Surname-and-geography ethnicity estimates for outreach planning
• Walk lists, mail lists, and canvassing packets
• Portable CSV export for field, mail, and voter-file cleanup

No paperwork. The data is part of onboarding.

In most states, VoterFile preps the voter-file request and the candidate signs as requester of record. Missouri is simpler: the file is public to anyone, so there is no request for you to sign at all.

Sign the services agreement and we obtain the official file and load your voters, typically within days. Refreshes come straight from the Missouri Secretary of State, Elections Division (or your county election authority) on the state's own update cadence, at no charge, for the length of your race.

• Sign the services agreement — that's the whole checklist
• We obtain the official file and load your county or district
• Refreshed from the official source through your race, never a data charge

Built for the races the big vendors skip

The national voter-data vendors are priced and built for statewide and federal campaigns. A first-time candidate for Missouri city council or school board is too small for that model and ends up with a spreadsheet.

VoterFile is the opposite wedge: a flat one-time software fee per race, your own data, and no annual data contract. It is aimed squarely at the local challenger in a low-turnout race.

• Flat one-time per-race software fee, not a yearly data contract
• You bring your own file, so you are never paying for the data itself
• Designed for city council, school board, and special-district races

How onboarding works

First you sign a short services agreement that keeps VoterFile as your data processor, with no sale, no pooling, and deletion on request. Then we obtain the official Missouri file, load it into your workspace, and score it — no upload, no request.

Nothing moves until the agreement is signed, and your file lives in a workspace no other customer can reach. When your race is over, or any time you ask, your file and the lists are deleted.
