FAR 4.1602 Identifying the PIID and supplementary PIID.

The codified text (eCFR, as of 2026-10-02). Under the Revolutionary FAR Overhaul ↗, agencies follow class deviations with new text for many parts while the formal rules go through the Federal Register: check the solicitation and your contract's clauses, which rule.

In plain English

This section requires agencies to include Procurement Instrument Identifiers (PIIDs) and supplementary PIIDs in solicitation and contract award documentation, including forms and electronic formats. It specifies which PIIDs to identify for different procurement actions, such as solicitations, contracts, orders, and modifications. Contractors will see these identifiers on solicitations and contracts, which helps track and reference specific procurement actions.
