Previously, Kansas voters had until three days after Election Day for their mail ballots to arrive at election offices. Now, ballots must be received by 7:00 on the evening of Election Day to count.
In December, USPS announced that in 2026 it will postmark mail when it's processed at regional facilities rather than when it's dropped off. This processing delay could take several days, meaning a ballot mailed on time could still arrive too late to count.
For documents with hard deadlines, the Postal Service recommends bringing items to a Post Office counter and requesting a manual local postmark. This service is free and will always show the date you handed over your mail.
The Postal Service also suggests mailing items at least a week before deadlines and purchasing a Certificate of Mailing for proof of submission when necessary.
