PSC R604

Overview

The Product Service Code (PSC) system is the federal government’s standardized taxonomy for classifying goods and services in procurement records to support reporting, spend analysis, and award tracking across FPDS and related systems. The PSC Manual on Acquisition.gov publishes the official code list and maintenance procedures; agencies and data tools reference that manual for authoritative code definitions and usage guidance. PSC R604 — SUPPORT‑ADMINISTRATIVE: MAILING/DISTRIBUTION — identifies government purchases of mailing, parcel, and distribution services (mailroom operations, bulk mail handling, distribution centers, routing and tracking) and is commonly paired on award records with courier/express NAICS classifications when commercial courier activities are involved. ¹

Contracting considerations

• Typical procurement approaches include task/delivery orders, blanket purchase agreements, and schedules for recurring mailing and distribution needs; accurate PSC reporting on the award record supports proper FPDS indexing and downstream spend analysis. ³
• Agencies commonly record an associated NAICS (for example, NAICS 492110) to reflect the primary industry classification for the awarded supplier when the contractor’s primary activity aligns to commercial courier/express or distribution operations. ²

Frequently asked questions

• Q: How is PSC R604 different from R602?
  A: PSC R604 covers broader mailing and distribution services—bulk mail, sorting, distribution centers, and mailroom operations—while PSC R602 specifically denotes courier and messenger services; both codes may appear on an award when contract scope includes both mailing/distribution and courier functions. ¹

• Q: Which NAICS codes typically align with R604 on awards?
  A: Awards using PSC R604 commonly report NAICS 492110 when the work represents commercial courier/express activities; agencies should select the NAICS that best represents the primary industry of the supplier’s performance. ²

• Q: Where do I find the official PSC definitions and updates?
  A: The authoritative PSC Manual and the published PSC code lists and maintenance guidance are available on Acquisition.gov; agencies and contracting officers should rely on that manual for official definitions and the current code set. ¹
