The US Postal Service (USPS) now postmarks mail at the time it gets sorted, not at the time it’s left at a USPS mailbox or picked up by a mail carrier. To ensure you meet ‘mail by’ deadlines, CTDOL recommends visiting the Post Office service desk to have your item postmarked the same day that it’s dropped off.
Our offices are closed on Thursday, February 12, 2026 in observance of the holiday.
