Some mail sent via the United States Postal Service may no longer be postmarked on the same day it’s sent. This change comes as USPS is implementing updates as part of its long-term transformation plan, which includes rate adjustments expected to take effect in 2026.
According to a statement from the USPS, operational changes in transportation may result in some mail arriving later at processing facilities, potentially affecting the postmark dates. Typically, postmarks are applied by machines at outgoing processing centers instead of local post offices. This means the date on the postmark might indicate when the mail was actually processed rather than when the sender mailed it.
Martha Johnson, a USPS spokeswoman based in Washington, D.C., explained that the update’s goal is to clarify what postmarks represent and their application timing. She noted, “This isn’t about changing the process but rather improving public understanding of what a postmark shows, including its relevance to the mailing date.”
If someone wants a postmark that matches the mailing date, they can request a manual postmark at local USPS locations. This can be done at no extra charge when the mail is handed to a clerk at a retail counter.
In addition, starting January 18, 2026, USPS will increase shipping rates, with increases around 5% to nearly 8% for major services like Priority Mail, Priority Mail Express, and others. However, the price of first-class postage stamps will stay the same. USPS asserts that these changes are part of a broader 10-year plan aimed at achieving financial sustainability and adjusting rates based on market conditions.
