PSC 3550

Overview

The Product and Service Code system classifies federal purchases by the type of goods or services acquired, supporting standardized reporting and analytics across FPDS and related acquisition systems. The codes and definitions are maintained through the official PSC Manual and updated periodically by GSA. ¹

3550 identifies Vending and Coin Operated Machines within Federal Supply Group 35 (Service and Trade Equipment). The PSC Manual specifies inclusions such as fare recording devices, parking meters, turnstiles, and coin-operated phonographs, and exclusions such as coin/currency handling machines and coin-operated scales, guiding correct coding of machine end-items in contract actions. ¹
