This legislation mandates that the Postal Service review and implement specific recommendations from the Inspector General of the United States Postal Service. These recommendations are detailed in the Inspector General's report titled "Delivery Operations--Undelivered and Partially Delivered Routes" (Report Number 21-262-R23), which was issued on December 16, 2022. The primary goal of these recommendations is to enhance the Postal Service's ability to identify and notify customers about undelivered and partially delivered mail routes. The Postal Service is required to implement these improvements to the extent practicable, with a strict deadline of one year following the bill's enactment.
