FAR and DFARS › DFARS Part 252: Solicitation Provisions and Contract Clauses › Subpart 252.2

DFARS 252.211-7008 Use of Government-assigned Serial Numbers.

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 clause requires contractors to mark Government-assigned serial numbers on major end items listed in the contract Schedule, following the technical instructions in the contract. Contractors must also register that serial number along with the item's Unique Item Identifier (UII) at delivery, and establish a UII for the item's life. It matters because it sets specific marking and reporting duties tied to delivery of major end items.

Applies to: Contractors delivering major end items under contracts that include this clause

What it requires

  • Mark the Government-assigned serial numbers on major end items as specified by line item in the Schedule, following the contract's technical instructions for placement and application
  • Register the Government-assigned serial number along with the major end item's UII at the time of delivery, per DFARS 252.211-7003(d)
  • Establish the UII for major end items for use throughout the life of the item

The text

As prescribed in 211.274-5(b), use the following clause:

Use of Government-assigned Serial Numbers (SEP 2010)

(a) Definitions. As used in this clause—

Government-assigned serial number means a combination of letters or numerals in a fixed human-readable information format (text) conveying information about a major end item, which is provided to a contractor by the requiring activity with accompanying technical data instructions for marking the Government-assigned serial number on major end items to be delivered to the Government.

Major end item means a final combination of component parts and/or materials which is ready for its intended use and of such importance to operational readiness that review and control of inventory management functions (procurement, distribution, maintenance, disposal, and asset reporting) is required at all levels of life cycle management. Major end items include aircraft; ships; boats; motorized wheeled, tracked, and towed vehicles for use on highway or rough terrain; weapon and missile end items; ammunition; and sets, assemblies, or end items having a major end item as a component.

Unique item identifier (UII) means a set of data elements permanently marked on an item that is globally unique and unambiguous and never changes in order to provide traceability of the item throughout its total life cycle. The term includes a concatenated UII or a DoD-recognized unique identification equivalent.

(b) The Contractor shall mark the Government-assigned serial numbers on those major end items as specified by line item in the Schedule, in accordance with the technical instructions for the placement and method of application identified in the terms and conditions of the contract.

(c) The Contractor shall register the Government-assigned serial number along with the major end item's UII at the time of delivery in accordance with the provisions of the clause at DFARS 252.211-7003(d).

(d) The Contractor shall establish the UII for major end items for use throughout the life of the major end item. The Contractor may elect, but is not required, to use the Government-assigned serial number to construct the UII.
