The United States Postal Service will comprehensively extend the delivery time of mail
Recently, the United States Postal Service (USPS) announced the implementation of the second phase of service standard optimization. The new regulations will expand the 2-4 day delivery range for first-class mail and ground advantage mail, and improve the efficiency of local mail "turnover" processing. The delivery time for first-class mail and ground advantage mail has generally been extended from 1-3 days to 2-4 days, and in some remote areas, it may even take up to 6 days
