DA Form 1669: Request NSN & DODIC | Download PDF – DA Form 1669 is an official U.S. Army form titled “Request for National Stock Number and Department of Defense Identification Code for Ammunition and Explosive Supplies.” Released in its current edition on October 1, 1976 (replacing the March 1, 1956 version), it serves as the standardized document for requesting assignment of a National Stock Number (NSN) and Department of Defense Identification Code (DODIC) for ammunition and explosive items.
This form is essential for the proper cataloging, identification, procurement, storage, and issuance of munitions within the Department of Defense supply system. It is referenced in TB 9-1300-256 (Ammunition: National Stock Numbers and Department of Defense Codes).

Purpose of DA Form 1669
The primary purpose of DA Form 1669 is to initiate the process for obtaining an official NSN and DODIC for new or modified ammunition and explosive supplies. These identifiers ensure:
- Accurate identification across the DoD supply chain.
- Interchangeability tracking — The DODIC (a letter followed by three numbers, e.g., C445) denotes items with the same purpose that can be used interchangeably, even if model numbers differ.
- Compliance with logistics, safety, transportation (DOT regulations), and storage requirements (Quantity-Distance classifications).
- Support for type classification and procurement decisions.
Engineering activities use the form to provide detailed technical data so the Defense Logistics Agency (or relevant cataloging activity) can assign the proper codes. Processing should start at least 120 days before key milestones like IPR III (DEVA) to avoid delays.
Who Uses DA Form 1669?
- Army engineering and maintenance activities responsible for ammunition items.
- Organizations developing or modifying explosive supplies, packaging, or related components.
- Personnel involved in munitions cataloging, supply management, and logistics support within the U.S. Army and broader DoD.
It is not typically used by general units for routine requisitions but by technical/engineering offices preparing items for formal supply system entry.
Key Sections of DA Form 1669
The two-page form is divided into clear sections:
Section A – Description of Item Requiring National Stock Number and DOD Identification Code
- Complete nomenclature.
- Packing details (inner, intermediate, outer; waterproofing, etc.).
- Grade (if applicable).
- Drawing numbers (including revisions) for the complete round, container, and markings.
- Quantity-Distance class for storage.
- Pounds of explosive per package.
- Outside dimensions of outer container (length, width, height).
- Average weight (packaged).
- Marking required by DOT regulations.
- Security classification.
- Quantity on hand and to be produced.
Section B – Basis for Request
- Details supporting the request, including condition and source information.
Section C – Indorsement/Authorization
- Approval or assignment decisions, such as new NSN/DODIC assignment or alternative identification.
- Signatures from requesting and approving offices.
Pro Tip: Provide comprehensive data—including full descriptions, drawings, interim hazard classifications, packaging methods, and weights—to prevent the form from being returned for incompleteness.
How to Fill Out and Submit DA Form 1669?
- Gather supporting documentation — Drawings, hazard classifications, packaging specs, and technical data.
- Complete Section A with precise item details.
- Obtain approvals — Ensure the requesting office signs and includes typed name, grade, and title.
- Submit through appropriate engineering/supply channels to the cataloging activity (per TB 9-1300-256 guidance).
- Track the request for NSN/DODIC assignment.
The form is fillable and available as a PDF from official Army sources. Always use the latest version from Army Publishing Directorate.
Importance in Army Ammunition Management
Accurate NSNs and DODICs are critical for:
- Requisitioning and issue (often used with systems like TAMIS).
- Safety and compatibility (storage, transportation, and handling).
- Inventory management and interchangeability.
- Compliance with federal regulations for explosives.
Without proper assignment via DA Form 1669, new ammunition items cannot be efficiently integrated into the DoD supply system.
