Changes to U.S. First-class Mail delivery times may affect you

U.S. Postal Service Priority Mail products and First-Class packages may require more time to be delivered due to limited transportation availability as a result of the ongoing Coronavirus Disease (COVID-19) impacts to the United States.
What is happening:
Effective October 1, 2021: The United States Postal Service (USPS) has revised its service standards for certain First-Class Mail items, resulting in a delivery window of up to five days. Please note that this may delay your receipt of mail from us and our receipt of mail from you (including mailed payments). Please take this change into account when mailing items to us via USPS. For more information, visit the USPS website.
Effective April 17, 2020: The Postal Service’s flagship Priority Mail Express service, which guarantees overnight service, will not change.
Service commitments for local 1-day Priority Mail will not change.
Priority Mail’s two and three day service commitments now will be extended to three and four days respectively. Customers will continue to receive end-to-end visibility and improved product tracking, as well as up to $50 in free insurance. With the extra day extension, customers should expect delivery using Priority Mail Open and Distribute (PMOD)to range from two to four days nationwide.
First-Class Package Service (FCPS) two and three day service commitments will also be extended to three and four days respectively.
Global Express Guaranteed Services also have been altered. For a full list of international and domestic updates, refer to usps.com
The Postal Service’s goal continues to be to move packages as expeditiously as possible.
The Postal Service continually reviews its network capacity to provide the American public reliable, efficient, and fast-delivery service. 
We will continue to keep you abreast of improvements in transportation availability and when we will be able to return to normal service levels.
