Short answer: In the United States, mail delivery generally continues on Election Day, including regular USPS service, with special measures in the days leading up to and on Election Day to ensure ballot mail is delivered on time. Other carriers (UPS, FedEx) also operate with their usual schedules, depending on local operations and holiday policies. If you’re mailing a ballot or letters on Election Day, you should typically still have mail delivery and pick-up, but it’s wise to check local post office hours and any state-specific ballot deadlines. Context and details

• Postal service: USPS typically maintains regular delivery on Election Day. In recent elections, USPS has implemented additional “extraordinary measures” in the final days to expedite ballot processing and delivery, including special pickups and expedited sorting for Ballot Mail. This helps ensure ballots reach election officials by the required deadlines [USPS policy statements and coverage in recent election cycles].
• Other carriers: UPS and FedEx generally operate on their standard schedules on Election Day, including local pickups and deliveries, though times can vary by location and service level. Local store hours may differ, especially for USPS counter services, but mail delivery itself is usually ongoing [general carrier practices and election-day coverage].
• Voter considerations: To maximize the likelihood that your ballot or mail-in item arrives on time, consider:
  • Mail early: Mail ballots well before the state's return deadline if possible.
  • Use trackable options: If available, opt for tracking to confirm delivery or pickup status.
  • Check local deadlines: Ballot submission deadlines vary by state and county; some jurisdictions require ballots to be received by a certain time on Election Day, while others count ballots postmarked by Election Day but received later.
  • Polling-day mail: For non-ballot mail, standard USPS hours typically apply, but post offices may have modified hours in some regions; plan accordingly.
