Mail stolen from a California post office may have included vote-by-mail ballots, exposing a clear chain-of-custody gap before election officials ever saw them.
Story Highlights
- Officials confirmed a mail theft at a Daly City postal facility; ballots may be involved.
- Investigators have not yet determined how many ballots were affected, if any.
- County urged voters to track ballots and request replacements if needed.
- Theft spotlights a real weak point in mail voting: custody before elections staff receive ballots.
What Happened At The Daly City Post Office
San Mateo County elections officials said they were notified about a mail theft at the Sullivan Avenue post office in Daly City. The United States Postal Inspection Service opened an investigation. Local reports said the stolen mail may have included vote-by-mail ballots, but officials did not yet know how many ballots, if any, were taken. The incident occurred as voters had begun sending ballots ahead of the November election, raising concern that some ballots never reached the county.
County leaders told voters to use California’s ballot tracking tools and to request a replacement if their ballot did not show as received. Officials explained that tracking shows when a ballot is mailed, received, and processed. They also said a replacement ballot is available if a voter is worried their first ballot was lost in the theft window. This guidance signals that the county views the theft as a real operational risk that needs quick action from voters to prevent disenfranchisement.
Why This Exposes A Real Chain-Of-Custody Vulnerability
Reports identified the theft point as the post office or loading dock area, before ballots reached election staff. That reveals a weak link outside the county’s direct control. When mail sits on a dock, gets sorted, or moves between trucks, it is not yet in the hands of trained election workers. Thieves took mail from that zone, which is exactly where a mailed ballot can be lost or delayed without any election official seeing it in time.
Officials have not shown evidence that ballot envelopes were targeted, and they have not identified any fraudulent votes from this theft. Still, the core problem is exposure. If someone steals mail that includes sealed ballots, some voters may think they voted when their ballot never arrives. That forces voters to track, call, or travel in person to fix it. Each extra step hits trust and adds stress during the final election push.
What Officials Say Safeguards Can And Cannot Do
San Mateo County says every vote-by-mail packet links to a single voter. The county says only one ballot per voter will be counted, and its process rejects duplicates. That means a stolen ballot should not allow two votes for one person to be counted. It also means a replacement ballot should cancel out a stolen original if the thief tries to return it later with a forged signature.
Those are important safeguards, but they do not fix the first problem: a voter’s original ballot may never arrive. Tracking and replacements help, but only if voters act fast and have time to respond. The county stressed that mail voting remains safe and convenient. Yet officials also admitted they do not know whether any ballots were actually taken or how many pieces of election mail were exposed in this theft.
Practical Steps For Voters And A Policy Test For Leaders
Voters in the affected area should check their ballot status today. If the system does not show “received,” they should request a replacement or consider voting in person. They should sign the envelope clearly and return it using a staffed vote center or secure drop box. These simple steps make sure a single, valid ballot is counted and not delayed by postal issues tied to the theft window.

Leaders should review postal facility security at the dock, where the theft occurred, and improve camera coverage, access controls, and custody logs. County officials and federal postal inspectors should publish a clear count of any ballot envelopes in the stolen mail once they know it. They should also disclose how many replacement ballots were issued and how many original ballots later arrived. These facts will show whether safeguards worked in the real world, not just on paper.
