The U.S. Postal Service considers mail to be delayed when it is not processed in time to meet the established delivery day. Delayed mail can adversely affect Postal Service customers and harm the organization’s brand.

Mail originating from one mail processing facility that requires additional processing at a destinating facility before delivery is part of the Managed Mail Program. Once managed mail is processed, it is prepared for Delivery Point Sequence, which is an automated process of sorting mail into delivery order. DPS requires sorting the mail twice, with a first pass to sequence the mail and a second pass to sort the sequenced mail by each carrier.

To track mail conditions at processing facilities, the Postal Service launched the Mail Condition Visualization system in January 2019. The system provides near real-time visibility of a facility’s on-hand volume, delayed processing volume, and delayed dispatch volume. Specifically, the MCV system calculates:

  • Late arriving containers – containers that arrived from another processing plant after the Critical Entry Time1 necessary to meet their delivery commitment for their class and shape.
  • Delayed inventory – mailpieces that have not received their next expected processing operation scan by 6:59 a.m. for destinating final processing operations and by 6:00 a.m. for all other operations.
  • Delayed dispatch containers – containers that have not received a final dock (departure) scan more than 15 minutes after the Dispatch of Value.2

From January 1, 2020, through March 31, 2021, the Denver, CO, Processing and Distribution Center (P&DC) reported 6,280 late arriving containers, 2.2 billion pieces of delayed inventory, and 168,490 delayed dispatch containers. This site was judgmentally selected based on the high number of delayed dispatch containers during this time period.

    What's with packages being stranded in the Denver distribution center for three or more days??? IMHO, it's time to replace Postmaster General DeJoy. Be it intentional or not, he's killing the USPS.

    We sent a Priority Mail envelope from Indiana to Broomfield CO on January 25th. It arrived at this facility on January 26th, left the Denver Regional Facility on January 31 and is still showing 'In Transit'. Last year, we sent our niece's birthday card in May. She received it in October.

    Have also been waiting on Denver distribution center, like many others. Day 8 since my item has arrived there and no update since. what should have been a 3 day delivery is turning into a 10+day delivery. Something or someone over at denver distribution center needs to be fixed.

    Four packages, all the same size and approximate weight (under 1 lb) were delivered at a USPS mailing facility in Denver. All four were mailed with Priority Mail paid on them. 1 of the four was processed and delivered, to Richardson TX within 3 days. Of the remaining 3, 1 is still in "possession of the USPS" after 8 days; 1 did not depart the Distribution Center for 2 days; and 1 did not ARRIVE at the Distribution Center until 8 days later. This kind of service is typical of the Denver Distribution Center. Four packages, all the same, weight and shape, mailed Priority Mail on the same day are treated differently and all four leave the Distribution Center on different days. It's obvious something is wrong at the USPS in Denver CO.
