The U.S. Postal Service will no longer deliver mail to the door for new addresses, pushing mail recipients to instead cluster their mailboxes in a centralized area.
The new policy marks a sharp shift as the agency continues to find ways to cut costs and follows through on a proposal for which it has long advocated. USPS announced the change in a recent update to its Postal Operations Manual, in which it also made “centralized delivery” its preferred method of dropping off mail. Having letter carriers deliver mail to a cluster of mailboxes rather than to each individual door allows for more efficient routes that can be completed more quickly.
