On July 28 2021, the Postal Regulatory Commission (PRC) approved the proposal to increase the maximum size of a Commercial Presorted and Automation First Class Postcard (Order 5946).
The new maximum size is 9 inches long by 6 inches high. The piece will have a thickness of .009 to 0.016 and is eligible for the card size prices. The change is effective August 29, 2021.
This is a value-added opportunity that the Postal Service and our customers have looked forward to for some time.
