NATO CAGE Codes (NCAGE) are five-character identifiers issued to non-U.S. entities through the NATO Support and Procurement Agency, while standard CAGE codes apply to U.S. contractors. U.S. firms dealing with international defense contracts must understand that foreign suppliers need NCAGE codes to register in SAM.gov and participate in NATO procurement. These codes enhance global defense contract efficiency and reduce friction in multinational transactions. The following sections explain how these codes affect your contracting operations.

ToggleUnderstanding the Difference Between CAGE and NATO CAGE Codes

When traversing the complex world of government contracting, understanding the distinction between CAGE and NATO CAGE Codes becomes essential for successful business operations.
The primary difference lies in geographical application: CAGE Codes are issued to entities within the United States by the Defense Logistics Information Service, while NCAGE Codes apply to organizations outside U.S. territories through the NATO Support and Procurement Agency.
The registration processes also differ greatly. U.S. contractors must register with DLIS and renew their CAGE Code annually. Both CAGE Codes and UEIs are automatically assigned when businesses complete their SAM.gov registration. These codes maintain a standardized five-character length regardless of the issuing country or entity type.
In contrast, international entities obtain NCAGE Codes through the NATO Codification Tools ePortal, followed by email validation.
Though both codes function within the NATO Codification System, they serve different regional needs while maintaining the same purpose—establishing unique identifiers for entities contracting with government and defense organizations. These unique identifiers are crucial for companies seeking federal opportunities including contracts and grants with U.S. government agencies.
Why NATO CAGE Codes Matter for International Defense Contracting

In the complex ecosystem of international defense contracting, NATO CAGE Codes serve as fundamental identifiers that reveal numerous operational and commercial opportunities for global suppliers.
These codes function as mandatory prerequisites for non-U.S. entities seeking to register in SAM.gov and participate in U.S. defense contracts, effectively revealing NATO’s $1.2B annual procurement marketplace.
NATO CAGE Codes unlock international defense contract opportunities, serving as the gateway to a $1.2B procurement ecosystem for qualified global suppliers.
The standardized identification system enhances procurement efficiency across NATO’s 30+ member nations, reducing transactional friction in multinational defense contracts. Unlike U.S. CAGE Codes which are assigned by the Defense Logistics Agency, international codes follow different issuance protocols.
Companies with valid NCAGE codes gain eligibility for NATO Maintenance and Supply Agency tenders while meeting security compliance requirements. These codes are assigned by NSPA through the NATO Codification Tool for international businesses seeking government contracts.
For global defense contractors, these five-year codes synchronize with SAM.gov renewal cycles, preventing potential contract breaches and ensuring continuous participation in NATO-led procurement actions. The CAGE Public system offers unified search functionality for verifying and locating valid CAGE codes across participating nations.
How to Obtain and Maintain Your NATO CAGE Code Status

Securing a NATO CAGE Code requires careful navigation through specific registration channels and documentation requirements. Non-U.S. entities must register through NSPA’s ePortal, while U.S. contractors operate through the DLA CAGE Program Office.
The application process involves submitting accurate business information, including legal name, physical address, and designated Point of Contact details. Upon submission, applicants receive validation emails requiring verification before code assignment.
Once obtained, compliance requirements include:
- Cross-referencing the NCAGE in SAM registrations
- Maintaining accurate entity information
- Notifying contracting officers of changes within 30 days
- Ensuring subcontractors maintain valid codes
Organizations should audit their NCAGE information annually against SAM records to prevent contract disruptions, as discrepancies can delay payments and create compliance issues. Before applying for a CAGE Code, businesses must first obtain a DUNS number which serves as a unique identifier for your company in government contracting systems.
Frequently Asked Questions
Can Cage/Ncage Codes Be Transferred During Company Mergers or Acquisitions?
CAGE code transfers can occur during mergers or acquisitions through a novation process. This procedure allows contract obligations to transfer between entities, requiring notification to contracting officers and appropriate documentation of merger implications.
Do Subcontractors Need Their Own NATO CAGE Codes?
Yes, subcontractors require their own CAGE/NCAGE codes for each physical performance location. Subcontractor responsibilities include obtaining and maintaining valid codes through proper registration processes and updating information within SAM.gov when changes occur.
What Happens if NATO CAGE Information Conflicts With SAM Registration Data?
CAGE code discrepancies with SAM registration data trigger system flags, resulting in registration holds until resolved. Entities must update information through the appropriate agency and may face procurement disqualification or payment delays until corrected.
Are CAGE Codes Required for Non-Defense NATO Procurement Opportunities?
Yes, CAGE codes are typically required for non-defense NATO procurement opportunities. Organizations seeking to participate in NATO procurement must obtain appropriate CAGE/NCAGE codes regardless of whether the contract involves defense-related activities.
How Do CAGE Codes Affect International Traffic in Arms Regulations Compliance?
CAGE code compliance plays a critical role in International Traffic in Arms Regulations by enabling verification of authorized suppliers, tracking defense articles across borders, and documenting the supply chain for international arms regulations adherence.
