Late Postmarks Threaten Mail-In Ballots Sent Near Election Day

Originally reported by NPR News. NPR News

Voters who mail their ballots close to Election Day risk disqualification because the U.S. Postal Service may not apply a timely postmark to their envelopes.

Election officials across the country face challenges with mail-in ballots that arrive after the deadline without a clear postmark, according to NPR News. While many states require ballots to be postmarked by Election Day to count, the automated processing systems used by the USPS do not always stamp every piece of mail with a date.

Postmarking Challenges and Deadlines

The USPS uses high-speed sorting machines that occasionally skip the postmarking process for certain types of mail, according to reporting by NPR News. This technical gap creates significant hurdles for voters in states where the law strictly mandates a visible, timely postmark for a ballot to remain valid.

Election experts suggest that voters who wait until the final days of the election cycle should consider alternative delivery methods. According to NPR News, using official drop boxes or delivering ballots directly to local election offices ensures that the documents meet the necessary deadlines without relying on the postal system’s processing window.

Recommendations for Voters

The USPS recommends that voters mail their completed ballots at least one week before their state's deadline, according to NPR News. This buffer allows for transportation time and increases the likelihood that the envelope receives the required cancellation stamp at a processing facility.

Voters can also request a manual postmark at a post office counter to guarantee a date stamp, according to NPR News. This extra step provides a physical record of the mailing date, which protects the ballot from rejection if delays occur during transit to the registrar.
