“As announced in the March 5 Federal Register Final Rule the Postal Service is revising Destination Sectional Center Facility (DSCF) Standard Mail service standards which allow the “load leveling” of mail volumes. This change will allow a more balanced distribution of DSCF Standard Mail across delivery days.
For those DSCF Standard Mail pieces entered on Friday or Saturday, the Postal Service is changing the current three-day delivery expectation to a four-day delivery expectation. And for pieces entered at the SCF in San Juan, PR and destined for the U.S. Virgin Islands, as well as all DSCF entry pieces destined for American Samoa, the delivery expectation for pieces entered on Friday or Saturday would change from four days to five days.
This change will not affect service standards for First-Class Mail or Periodicals. USPS is not proposing any other changes in its service standards at this time."
United States Postal Service
Implementation of the revised rules began April 10.
