What is a Ballot Drop Box?

A Ballot Drop Box is a secure, well-marked box where voters can return their completed ballot. Voters can return their ballot to any box. Ballot Drop Boxes are serviced by deputized employees of the County Elections Department working in teams of two.

How Often Are Ballots Collected?

Ballots are collected on a regular schedule multiple times a week by deputized employees of the County Elections Department working in teams of two. Pick-up frequency will be adjusted to accommodate higher volume. Ballots are sealed in secure containers during transport.

Is the Ballot Drop Box Secure?

Ballot Drop Boxes are constructed similarly to those used by USPS, FedEx and UPS.  Ballot Drop Boxes are bolted on the inside into concrete or secured to an immovable object using industrial strength hardware. The opening is narrow and designed in a way that prevents tampering or retrieval of envelopes. Each Ballot Drop Box is inspected by the pick-up team for damage or evidence of tampering. Local law enforcement agencies have been notified of the locations so they can monitor Ballot Drop Boxes daily while on patrol.

When are Ballot Drop Boxes Available?

Ballot Drop Boxes are available 24/7 starting 28 days before an election. The number of Ballot Drop Boxes vary by election. On Election Day, all Ballot Drop Boxes will be closed and locked precisely at 8 p.m.
