USPS set to start slowing some mail delivery

Mail delivery for many Americans will slow starting on Friday, part of Postmaster General Louis DeJoy's blueprint for overhauling the U.S. Postal Service in order to slash costs. But critics say the slower delivery standards could cause problems such as late bill delivery while more broadly undermining the public's faith in the USPS. 

Almost 4 of 10 pieces of first-class mail will see slower delivery, according to Paul Steidler, senior fellow at the Lexington Institute and an expert on the postal service. That "means mail delivery will be slower than in the 1970s," he said, calling DeJoy's plan "disastrous."

Starting tomorrow, the postal service's current three-day delivery standard for first-class mail — letters, bills, tax documents and the like — will drop to delivery anywhere within the U.S. within five days. In other words, Americans should now expect that letters and other mail could take up to five days to reach their destinations, and vice versa.
