The US Postal Service is simplifying how it sorts mail, cutting three old lists

The US Postal Service is eliminating three of its mail sorting lists and redirecting those mail types to existing lists. This is the first step in moving to a new system based on mail shape.

For decades, the Postal Service has used complex sorting rules that made it harder for large mailers to prepare their shipments. Simplifying these lists means less complexity for businesses that send a lot of mail. This could lead to faster processing and fewer errors, making the mail system slightly more efficient.
