About the company

United States Postal Service National Customer Support Center Division, operating as US Post Office, provides address verification and change-of-address data services to federal agencies as a prime contractor through purchase orders and subscriptions. The division is a component of the USPS parent entity, a self-sustaining independent federal agency headquartered in Washington, DC, with the National Customer Support Center Division based in Memphis, Tennessee. USPS operates exclusively on full-and-open, non-set-aside basis across all recent awards.

The division's core capability centers on National Change of Address Link (NCOALink) licensing and subscription services, supplemented by Address Management System (AMS) licenses and postal infrastructure services. Recent representative work includes a $1.192 million full-service provider license to the Internal Revenue Service for NCOALink with FastCheck (48 months of weekly change-of-address data access, awarded October 1, 2025, with performance through September 30, 2028); a $895,500 NCOALink product license to the IRS for taxpayer notice mailing operations (fiscal years 2022–2025); and recurring annual subscriptions to the Social Security Administration ranging from $12,200 to $19,770 for NCOALink with AnkLink end-user access. The division also provides PO box rentals and basic postal services across federal agencies.

Customer concentration skews heavily toward Internal Revenue Service and Social Security Administration. The top five customer agencies by count include Naval Supply Systems Command (14 awards, $92 thousand), Social Security Administration (5 awards, $78 thousand), and Veterans Affairs Technology Acquisition Center Austin (5 awards, $80 thousand), but the dollar rankings diverge significantly: IRS dominates combined potential value at $3.4 million across 4 awards (79% of the division's $4.3 million portfolio), while Veterans Health Administration Veterans Integrated Service Network 22 holds a single $355 thousand award. The 21 distinct customer agencies served indicate broad federal reach, though activity concentrates on civilian agencies with high-volume mail operations and address-data dependencies.

Activity has remained sparse and episodic—three awards in 2022, declining to one award each in 2023 and 2024, rebounding to three in 2025, and one award recorded in 2026. The combined potential value across all 135 awards is $4.3 million, with $3.4 million obligated (80% execution). Only three awards face ultimate completion within the next twenty-four months, combined potential value $48 thousand, indicating minimal near-term recompete exposure for the division's current contract portfolio. USPS holds no subcontractor footprint; all 135 awards are primes executed by the division itself. Award category concentration reflects postal and mailing services posture: 24 awards fall under Postal Service NAICS, with 37 awards coded to Office Supplies PSC and 19 to Support – Administrative: Post Office PSC.
