Subpart 4.16
Unique Procurement Instrument Identifiers
Every federal procurement action must have a unique identifier (PIID) to ensure accurate tracking, reporting, and compliance throughout the contract lifecycle.
Overview
FAR Subpart 4.16 establishes the requirements for assigning and managing Unique Procurement Instrument Identifiers (PIIDs) for all federal contracts, orders, and related instruments. The subpart outlines the policy, identification standards, and procedures for creating, using, and supplementing PIIDs to ensure each procurement action is uniquely and consistently tracked throughout its lifecycle. This system supports transparency, auditability, and efficient management of procurement data across government agencies.
