This new change took effect on December 24th, 2025, but as you head into the new year, this is your heads up.

Here are a few options if you want a day of postal mark:

• Request a Manual Postmark: USPS 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.

• Postage Validation Imprint (PVI): When a customer pays for postage at a retail counter, the PVI label applied by the employee also indicates the date of acceptance.

• Certificate of Mailing: Customers may purchase a Certificate of Mailing, or use Registered or Certified Mail, to obtain a receipt that serves as evidence of the date the item was presented for mailing.

So there you are, it might be frustrating, but now you can plan around those pesky deadline dates to make sure your mail makes it in time.
