How reliable was the Postal Service in the 2020 general election?

According to the U.S. Elections Project, there were over 159.6 million ballots counted in the 2020 general election. The Postal Service processed and delivered at least 135 million ballots going to and from voters.

In the weeks leading up to the election, the OIG was on-site in postal facilities nationwide to provide real-time information on ballot processing and delivery. Processing of election mail was the Postal Service’s number one priority, and ballots were generally processed timely.

Although we identified challenges and recommendations for improvement, the Postal Service immediately corrected the issues we identified. The OIG will continue to provide oversight of mail-in ballot processing and delivery to ensure your vote is safely and reliably delivered.
