Oregon’s vote-by-mail system involves security measures that include the use of roughly 300 dropboxes and a tallying process for the ballots. According to a detailed behind-the-scenes report from the Oregon Capital Chronicle, this process relies on a series of physical locks, signature verification audits, and manual hand-counts to ensure that over 3.1 million ballots are processed without interference.
For voters, the stakes are simple: ensuring their voice is counted. For election officials, the stakes are the legitimacy of the democratic process itself.
From the Dropbox to the Sorting Tray
The journey starts with the physical collection of ballots. Election workers visit dropboxes—which are chained in place and often equipped with internal fire suppression systems—typically twice a day, though rural areas may only see a single visit. To maintain the chain of custody, workers carry affidavits proving their identity and the exact date of collection. Every collection bag is locked, ensuring that only the authorized worker can open it once the ballots reach the county clerk’s office.
Once inside, the ballots are sorted into trays. This is where the auditing begins. Each tray is paired with a yellow auditing form. This document tracks the number of ballots in the batch and notes any anomalies, such as missing signatures. This form acts as a permanent ledger, following that specific batch of ballots through to the final tally.
The Signature Guardrail
Before a ballot is ever removed from its envelope, it must pass a rigorous identity check. A machine scans the signature on the blue envelope, and an election worker then compares that image against the signature on the voter’s official registration using a monitor.
“I will take vote-by-mail over poll elections any day,” Richey told the Capital Chronicle. She noticed more mistakes in a polling system than in today’s vote-by-mail system, when previously she’d have to train inexperienced poll workers ahead of each election.
Oregon Staff Manually Verify Ballot Counts
To prevent machine error, Oregon employs a manual count. After an extraction machine separates the ballots from their blue envelopes, two different staff members count them separately. One person counts the envelopes; another counts the ballots. They record their totals silently and then compare their numbers. Only after these figures are verified does the batch move to a secure holding room.
The final tallying is done using Clear Ballot software. Once counted, the physical ballots are stored in a vault.
Data Shows Voter Fraud Rates Remain Extremely Low
The Brookings Institution analyzed fraud reports from 2016, 2018, 2020, and 2022, finding an average of only four cases of fraud for every 10 million mail ballots cast.
Oregon’s own internal data is even more stark. A study by the state’s nonpartisan Legislative Fiscal Office found that between 2000 and 2019, out of 61 million ballots cast, there were only 38 criminal convictions for voter fraud. That is a rate of 0.00006%.
Securing the Final Result
The final security layer is physical. Clerk offices utilize thick mesh glass to prevent break-ins and motion sensors that alert law enforcement immediately after hours. Until results are certified, even custodial staff are barred from rooms containing ballots. On election night, results are stored on a private flash drive that requires a specific code before the data can be sent to the Oregon Secretary of State.
This entire infrastructure grew from a simple 1981 experiment by former Linn County Clerk Del Riley, who wondered if mailing real ballots would save the county money on printing sample ballots. That test run saw voter turnout jump by nearly 20 percentage points, sparking a transition that made Oregon the first state in the nation to run all elections by mail by the year 2000.
