The U.S. Postal Service (USPS) said Monday it delivered at least 54.4 million ballots during the 2022 midterm general election, with almost 99% of ballots from voters to election officials delivered within three days.

Between Sept. 6 and Dec. 6, USPS delivered more than 54.4 million ballots to and from election officials to voters through the U.S. Mail, including votes in the Georgia runoff election for the U.S. Senate. The figure only includes ballots properly identified using the correct electronic identifiers and does not include ballots USPS diverted from its processing network or handled outside of normal processes in an effort to accelerate delivery.
