The Counterfeit Military Aircraft Parts Crisis

May 13, 2026 nick alvarez Aerospace

Non-conforming and fraudulent components can infiltrate even the most secure supply chains, especially as their producers are able to easily find and mimic the specifications of genuine articles. Aside from likely lacking the material strength, heat resistance, and rigorous testing required for military-grade applications, these products do not have the legitimate documentation that is legally required for their installment. To avoid the risk of purchasing any unusable counterfeits, defense logistics rely on a rigid framework of NSN verification and traceability, which extends to the Commercial and Government Entity (CAGE) code. This blog will take you through what exactly a CAGE code is and how it serves as a line of defense for military and aviation parts authentication.

Understanding CAGE Codes

A CAGE Code is a distinct 5-digit identifier for specific physical locations of a distributor, manufacturer, or other such entity. For instance, a major military aircraft parts supplier like Lockheed Martin utilizes dozens of CAGE codes so procurement officers can trace components back to their manufacturing plant, rather than just the location of their headquarters. The alphanumeric sequence of these codes does not indicate any specific information about the company, but the letters "I" and "O" are notably prohibited from them to ensure there is no room for confusion with the numbers "1" and "0."

In the United States, CAGE Codes are assigned and managed by the Defense Logistics Agency (DLA), while for other countries, these are referred to as NATO CAGE (NCAGE) codes and are assigned by the National Codification Bureau (NCB) of the country where the entity is physically located. If a nation does not have a dedicated NCB, the codes are instead managed and issued through the NATO Support and Procurement Agency (NSPA).

How CAGE Codes Support Authenticity in Defense Logistics

Since a CAGE Code is mandatory for every entity involved in a contract with the U.S. government, it serves as a very easy way to:

  • Vet Defense Supplier Compliance: Before an order is ever placed, a CAGE code lookup is performed to verify that the supplier tied to a component is active, registered in the System for Award Management (SAM), and cleared for government work.
  • Establish Clear Chains of Custody: In conjunction with supporting documentation like Certificates of Conformance (CoC) and shipping manifests, the CAGE code helps to verify that the item has moved through an authorized path.
  • Track Manufacturing Issues: If a component were to fail in service, the CAGE code allows investigators to immediately identify the facility responsible for its production rather than make them go through multiple avenues to track it down. In turn, this empowers targeted recalls and audits to determine if the failure was an isolated incident or a systemic manufacturing defect.

Methods for Authenticating CAGE Code Information

As some counterfeiters have the ability to replicate packaging and laser-etched markings very closely, buyers and quality control specialists cannot just take a provided CAGE code at face value. To fully validate a purchase, they will first examine the CoC to ensure it features the correct manufacturer’s CAGE code and is signed by an authorized quality representative. With DLA or NSPA databases, they can check further to make sure the information provided on the shipping labels and invoice match the logged facility address. Lastly, the 2D Data Matrix or linear barcodes required under MIL-STD-129 should correctly encode the CAGE code and match the human-readable text on the exterior packaging when scanned.
