This document is one in a series created as part of the Cybersecurity and Infrastructure Security 

Agency (CISA) Elections Infrastructure Government Coordinating Council and Sector 

Coordinating Council’s Joint COVID Working Group. These documents provide guidance for 

state, local, tribal, and territorial election officials on how to administer and secure election 

infrastructure in light of the COVID-19 epidemic. 

Ballot Drop Box 

Overview 

A ballot drop box provides a secure and convenient means for voters to return their mail ballot. 

A drop box is a secure, locked structure operated by election officials where voters may deliver 

their ballots from the time they receive them in the mail up to the time polls close on Election 

Day. Ballot drop boxes can be staffed or unstaffed, temporary or permanent. 

Unstaffed drop boxes are typically available 24 hours a day and permanently anchored in place. 

Staffed drop boxes are typically available during regular business hours and monitored by 

trained workers during those hours. 

Whether you are standing up a temporary vote-by-mail program statewide or locally, or you plan 

to develop a permanent program of voting primarily by mail, there are a few things to know and 

consider when planning for the use of ballot drop boxes. 

General Considerations 

Why do you need ballot drop-off locations when you are paying 

for return postage? 

Some voters prefer to deliver their mail ballots to a drop box rather than sending them back 

through the mail. These voters may be motivated by lack of trust in the postal process, fear that 

their ballot could be tampered with, or concern that their signature will be exposed. Voters may 

also be concerned about meeting the postmark deadline and ensuring that their ballot is 

returned in time to be counted. 

Ballot drop boxes and drop-off locations allow voters to deliver their ballots in person. More 

importantly, the availability of ballot drop boxes and drop-off locations ensures that even voters 

who wait until the last minute to vote or who receive their requested ballot in the mail at the last 

minute will be able to return their ballots in time to be counted.

Many of these last-minute voters drop their ballot off at a voting location (which may not be 

allowed by state law). Setting up ballot drop boxes and educating voters to use them mitigates a 

number of COVID-19-related risks associated with in-person voting. It also minimizes the 

number of people that will need to access voting locations, thereby providing more space for 

those who are engaged in in-person voting. 

How many ballot drop boxes will you need? 

At a minimum, you should have a drop box at your main county or city office building. Voters 

generally know the locations of these buildings and are already accustomed to voting or doing 

business there. Some other best practices include: 

❏ Have one drop box for every 15,000–20,000 registered voters. 

❏ Consider adding more drop boxes to areas where there may be communities with 

historically low vote by mail usage. 

❏ Use demographic data and analysis to determine whether there should be a different 

formula for rural and urban locations (i.e., 1 for every 15,000 residents may be every 

mile in an urban are, but every 50 miles in a rural area). 

To get a better idea of how many voters use ballot drop boxes when voting by mail is the 

primary method of voting, look at the Ballot Drop Box Usage chart put together by the 

Washington Secretary of State. It shows ballot drop box use as a percentage of total ballots 

returned for Washington state, where voting by mail has been the primary method of voting for 

over a decade. 

Timeline: The number of drop boxes and their locations should be finalized in time to be 

included in the instructions with your mail ballot packet—typically 80 days before the election. 

Where should ballot drop boxes be located? 

Ballot drop boxes should be placed in convenient, accessible locations, including places close 

to public transportation routes, near or on college campuses, and public buildings, such as 

libraries and community centers familiar to voters and easy to find. If there is time, getting input 

from citizens and community groups is recommended. 

All drop box locations should be evaluated for: 

❏ Security 

❏ Lighting (well-lit 24 hours a day) 

❏ High visibility 

❏ Security cameras (more on cameras in the Security Considerations section below) 

❏ Accessibility 

❏ Voter convenience 

❏ Parking or drive-through options

There are tools that can help you evaluate locations for drop boxes. The U.S. Census Bureau 

Interactive Workforce Map is a tool that can help you visualize where residents of your 

jurisdiction work or live to help you see where drop boxes might be particularly useful. Also, the 

Federal Emergency Management Agency (FEMA) is offering free enterprise-level access to 

ESRI geospatial mapping software for all state, local, territorial, and tribal governments for 6 

months. 

In a COVID-19 environment, creative solutions may be required. Consider: 

❏ Collocating a ballot drop box with drop boxes set up for taxes and public utilities. 

❏ Partnering with businesses or locations that have already implemented social distancing 

practices, such as grocery stores and banks. 

A great example of using existing spaces comes from Madison, Wisconsin. The city’s libraries 

were shut down owing to COVID-19. The City Clerk’s office decided to capitalize on locations 

that were already secure and located in places familiar to city residents. Working in partnership 

with the library, they used the book drops from three of the city’s public libraries and turned 

them into temporary ballot drop boxes. If you choose to do something similar, be sure to ask 

questions about the library’s security to ensure ballots dropped off at library locations remain 

secure at all times. 

Timeline: The locations of drop boxes should be finalized in time to be included in the 

instructions with your mail ballot packet—typically 80 days before the election. 

Who can collect and drop off a mailed ballot on behalf of a voter? 

Voters who are unable to return a ballot in person or get it to a postal facility in time for it to be 

counted may, depending on state law, may be able to entrust the voted ballot to someone else 

to help them deliver it—an agent or designee. Note that, as of March 30, 2020: 

● Twenty-seven states permit an absentee ballot to be returned by a designated agent, 

which can be a family member, attorney, or care provider. 

● Nine states permit an absentee ballot to be returned by the voter’s family member. 

● One state specifies that an absentee ballot can only be returned in person or by mail. 

● Thirteen states do not expressly address this issue. 

Some states that allow a designated agent to return a voted ballot on behalf of the voter restrict 

the number of ballots that can be deposited by that person at one time in a drop box. 

If you are considering the use of ballot drop boxes, you should review your existing laws and 

requirements and determine whether emergency changes may be necessary. A full list of state 

practices can be found at the National Conference of State Legislators (NCSL) website listed in 

the Additional Resources section.

What equipment and supplies are needed for ballot drop boxes? 

Whether you are collecting ballots just from a USPS facility, ballot drop boxes, or both, you will 

need ballot drop box collection teams. Ideally, these are bipartisan teams (poll workers or 

temporary workers) hired to drive a collection route and pick up ballots on a regular basis. Each 

of these teams will need: 

❏ Vehicle such as a van or SUV where the seats can be laid flat (county owned or rented) 

❏ Radio or cell phone 

❏ Secure ballot collection bag/box 

❏ Security seals 

❏ Chain of custody procedures/forms 

❏ Personal protective equipment (e.g. disposable, sterile gloves), as appropriate and in 

accordance to current CDC guidance 

Timeline: Reservations should be made as soon as possible if you plan to rent vehicles, radios, 

or cell phones—no later than 35 days before the election. 

Outlined below is a list of the typical items you will need to rent or buy, depending on the type of 

drop box or drop-off location you are installing. 

STAFFED – INDOOR TEMPORARY BALLOT DROP BOX 

When demand for a ballot drop box is low, a temporary ballot box located inside is a good 

solution. These boxes should be constructed of durable material and include a key or 

combination lock as well as a way to securely fasten the box to prevent it from being moved or 

tampered with. This type of box looks similar to the example pictured here. In addition to 

purchasing or renting the ballot box, you will need: 

❏ Padlock and keys (if not included) 

❏ Bike chain or some other way to fasten the box to prevent it 

from being removed (if not staffed) 

❏ Security seals 

Timeline: Depending on the lead time required by the manufacturer, 

boxes may need to be ordered 3 months in advance—90 days 

before the election. 

OUTDOOR, TEMPORARY DRIVE-THROUGH DROP OFF 

A drive-through drop-off location is an easy way to keep traffic flowing when demand for a ballot 

drop box is at its peak, especially on Election Day. This drive-through is typically set up in a 

parking lot or a street depending on the location. 

The team staffing the site accepts ballots from voters as they pull through, depositing them 

directly into a ballot box. For voters who prefer placing the ballot directly into the box

themselves, the portable ballot box is brought to the car window. In addition to the supplies 

listed below, you will need a bipartisan team of at least two to three to support the drop-off site. 

❏ Pop-up tent 

❏ Table 

❏ Chairs 

❏ Ballot box 

❏ Road signs 

❏ Orange cones 

❏ Flashlights 

❏ High-visibility vests for workers 

❏ Weather appropriate support— 

propane heater, rain gear, lanterns 

❏ Personal protective equipment such as gloves, masks, and hand sanitizer, as 

appropriate and in accordance with current CDC guidance 

Timeline: Most of these items can be purchased or rented locally. You will need some lead time 

to arrange for traffic signs and cones if they will be borrowed from law enforcement. 

UNSTAFFED, 24-HOUR BALLOT DROP BOX 

In high-demand areas where votes are or will be cast primarily by mail, installing a permanent 

ballot drop box—one that can be accessed by voters 24/7—is a good solution. These boxes 

should be constructed of durable material such as steel and be permanently cemented into the 

ground. This type of ballot drop box typically costs about $6,000 each. In addition to 

purchasing the 24-hour box you will need: 

❏ Video surveillance camera 

❏ Media storage device (for recorded video) 

❏ Decal (branding and information) 

❏ Extra keys for opening slot and access door 

❏ Security seals 

A good example of the security considerations associated with 

this type of box, pictured on the right, can be found in the 

California Code of Regulations. 

Timeline: Depending on the lead time required by the 

manufacturer, boxes may need to be ordered 4–6 months in advance—about 150 days before 

the election. 

Election Night and Closing Boxes 

You need to give special consideration to returning temporary ballot drop boxes and locking 

permanent drop boxes on election night. Organizing teams from other county or city 

departments is one way to accomplish this. Essentially, you need bipartisan teams to be at 

every ballot drop-off location precisely when polls close. Their responsibilities include: 

5 | Page

❏ Identifying the voter or car in line at the time polls close and ensuring they have the 

opportunity to deposit their ballots. 

❏ Retrieving the temporary indoor boxes and returning them to the counting facility. 

❏ Locking the drop slot on the 24-hour boxes and transferring ballots to a ballot transfer 

bag or box and returning them to the counting facility. 

❏ Completing chain of custody forms. 

Security Considerations 

Ballot drop boxes must be secured and locked at all times. Only an election official or a 

designated ballot drop box collection team should have access to the keys and/or combination 

of the lock. In addition to locks, all drop boxes should be sealed with one or more tamper 

evident seals. 

Ideally, unstaffed 24-hour drop boxes should be located in areas with good lighting and be 

monitored by video surveillance cameras. When this is not feasible, positioning the box close to 

a nearby camera is a good option. Also consider placing it in a high traffic area and inviting local 

law enforcement to make regular observations. 

Try to place indoor drop boxes in locations where they can be monitored by a live person. When 

ballot boxes are unstaffed and not being monitored, the box should be securely fastened to a 

stationary surface or immovable object in a way that prevents moving or tampering. 

Chain of Custody 

❏ Chain of custody logs must be completed every time ballots are collected. 

❏ All ballot collection boxes/bags should be numbered to ensure all boxes are returned at 

the end of the shift, day, and on election night. 

❏ Team members should sign the log and record the date and time, security seal number 

at opening, and security seal number when the box is locked and sealed again.

Safety 

❏ For drive-through locations, coordinate a traffic plan with public safety officials. 

❏ Consider colored vests for ballot collection teams. 

❏ Provide a radio or cell phone so you can stay in contact with collection teams at all 

times. 

Other Considerations 

Start thinking about a ballot collection plan. This should include: 

❏ Arranging with the USPS to designate a daily collection point for returned ballots and 

undelivered ballots. 

❏ Hiring bipartisan teams with clean driving records (review your jurisdiction’s 

requirements for driving as an employee). 

❏ Determining the frequency of collection prior to Election Day. 

❏ Determining the frequency of collection on Election Day. 

❏ Ensuring you have collection teams assigned to be at each location when polls close on 

Election Day. 

❏ Establishing best practices for transferring ballots back to the counting facility. 

❏ Preparing driving routes and accompanying maps or directions. 

❏ Determining how to keep collection teams and other staff safe in a COVID-19 

environment. 

❏ Reviewing your state laws regarding electioneering, campaigning, petition signature 

gathering, etc. at or near a ballot drop-off site. 

❏ Developing a plan for helping voters find ballot drop-off locations. This can include a list 

of locations in the mail ballot packet as well as an online lookup tool with maps and 

directions. Two examples are Lewis County, WA (rural county) and King County, WA 

(large urban county).
