Not sure why you're being downvoted. This is exactly what it is. Now mail-in ballots that previously had to be dropped in the box by election day have to be dropped off days in advance.
Request a Manual Postmark: Customers may present a mail piece at a retail counter and request a "manual (local) postmark". This postmark is applied at the time of acceptance, so the date aligns with the date the USPS took possession.
I should have said manual postmark but it’s what I implied. They’re stamping or postmarking it with a date manually.
