*U.S. Postal Service Rule Changes: Postmarks and Processing*
We are writing to inform you of a federal rule change that may impact all licensees. Through news stories, we recently learned of changes by the U.S. Postal Service [ [link removed] ] (USPS) related to mail processing and postmarks. We are sharing this information to make sure you are aware.
The changes took effect Dec. 24, 2025 and include:
* Now a postmark explicitly means the date that the USPS processed the item, which could be days later than when it was mailed.
* The postmark now reflects the date an envelope is "first processed" by an automated USPS sorting machine, "potentially days after it was dropped off – not the actual drop-off date."
The LCB, and many other agencies, have rules, processes, and timelines that are specific to postmark dates. The changes could result in late fees and penalties for anyone mailing time-sensitive documents or payments when a postmark is used to prove a deadline was met.
The changes mean that if you need to get a payment, official document, form, or other LCB-required correspondence submitted by a specific date or deadline, you may want to add extra time to allow for any delay between mail drop off and when a postmark is stamped.
