Location Of USPS Southern Maine Distribution Center
The Southern Maine Distribution Center for the USPS is located at 79 Postal Service Way, Room 1058, Scarborough, ME 04074, serving as the primary mail processing hub for southern Maine's high-volume operations.
Facility Overview
The Southern Maine Processing and Distribution Center (P&DC) in Scarborough handles outgoing mail sorting, package processing, and regional distribution for over 1.2 million residents across Cumberland and York Counties. Opened in its current form in 2015 following a $45 million modernization upgrade, it processes an average of 250,000 pieces of mail daily, peaking at 400,000 during holiday seasons like December 2024. USPS data indicates this facility reduced delivery times by 18% post-upgrade, outperforming national averages by 12 percentage points.
Unlike retail post offices, this carrier unit focuses exclusively on backend logistics, with no public counter services; visitors must use nearby branches like Scarborough Post Office at 31 Gorham Road, just 1 mile away. The site's strategic position near I-95 and the Portland International Jetport optimizes truck and air freight routing, supporting 24/7 operations for next-day delivery commitments. In fiscal year 2025, it achieved a 97.2% on-time performance rate amid national USPS reforms.
Historical Development
Established in 1982 as a supplemental sorting annex, the Scarborough facility evolved into Maine's flagship southern hub after consolidation efforts in the early 2000s. A pivotal 2024 USPS review initially spared the Eastern Maine P&DC in Hampden but shifted select operations-such as outgoing flats and periodicals-to Scarborough, investing $12.1 million in Hampden's conversion to a Local Processing Center instead.
- 1982: Initial carrier annex opens on Postal Service Way.
- 2015: $45M upgrade adds automated sorting lines for 60,000 parcels/hour.
- January 12, 2024: USPS letter confirms Hampden modernization, partial shift to Southern Maine.
- April 10, 2024: Official transfer of outgoing mail ops despite union opposition.
- September 2024: Proposal to fully merge Hampden operations terminated amid backlash.
"The Southern Maine P&DC will serve as a critical node in our regional ecosystem," stated USPS in a January 2024 union letter, emphasizing streamlined package capabilities and employee amenities. This decision followed public hearings where Maine Senator Susan Collins and Representative Jared Golden voiced concerns over potential delays.
