ROCHESTER, N.Y. — The United States Postal Service (USPS) is changing its postmark process, which could impact how important mail like bills and ballots are sent.
For decades, the postmark showed when mail was accepted by the post office and was used as proof that a deadline was met.
The postmark will now reflect the date an envelope is first processed by an automated sorting machine, not the drop-off date.
To ensure timely delivery, time-sensitive mail should be sent several days before a given deadline.
