CAGE Code Lookup: How to Find Aerospace Manufacturers, Suppliers & Parts

Posted on August 24, 2026 Jerold Perkins Aviation

A CAGE Code lookup helps buyers identify the company or facility connected to an aerospace part, supplier, or government procurement record. This five-character alphanumeric identifier represents an organization rather than a specific product.

For aerospace buyers, a CAGE search can help identify a manufacturer or supplier, connect an organization with a part number or NSN, research an unfamiliar source, and prepare an RFQ. However, the identifier alone does not confirm that a part is authentic, certified, available, or approved for a specific application.

What Is a CAGE Code?

CAGE stands for Commercial and Government Entity. The Defense Logistics Agency (DLA) assigns these identifiers to eligible entities in the United States and its applicable territories.

The identifier can represent an aircraft manufacturer, aerospace parts manufacturer, distributor, repair facility, government organization, or another entity involved in procurement. One company may have multiple codes for different facilities or locations.

Organizations outside the United States generally use NCAGE Codes, or NATO Commercial and Government Entity Codes.

Why Use a CAGE Code Lookup?

A company name alone may not always identify the correct source. Different businesses can have similar names, while one organization may operate several facilities or divisions.

Searching the identifier can help buyers:

  • Identify an organization connected with a procurement record.
  • Research aerospace manufacturers and suppliers.
  • Connect a supplier with a part number or NSN.
  • Find potential sources for aerospace components.
  • Research obsolete or hard-to-find parts.
  • Review supplier information before requesting pricing.

Government procurement records may show the identifier alongside a company name, manufacturer part number, NSN, or other purchasing information. Reviewing these details together can make parts research more accurate.

Where Can You Search for a CAGE Code?

The Defense Logistics Agency (DLA) provides official resources for finding and checking entity information. SAM.gov also provides official U.S. government registration information.

For aerospace parts research, Aerospace Exchange provides a CAGE Code directory where buyers can research identifiers and associated manufacturer and part information.

Commercial directories can support initial research, but important supplier and procurement information should be compared with official records and the requirements of the specific purchase.

What Does Aerospace Exchange Provide?

Aerospace Exchange helps buyers research CAGE Codes, manufacturers, suppliers, part numbers, and NSNs for aerospace and related components.

Users can search by the identifier, manufacturer name, part number, or NSN to research potential sources across aerospace, aviation, defense, MRO, electronics, and industrial manufacturing.

For a specific requirement, buyers can provide the available identifier together with the manufacturer part number, NSN or NIIN, quantity, condition, delivery requirements, and documentation needs when submitting an RFQ.

Aerospace Exchange supports parts research and sourcing. Buyers should still verify product authenticity, certification, condition, traceability, supplier authorization, and other applicable requirements before purchasing.

How to Perform a CAGE Code Lookup

Find the Identifier

You may find it on a government solicitation, purchase request, NSN record, technical document, maintenance record, supplier quotation, or previous order.

Enter the five-character identifier exactly as shown and check leading zeros carefully.

Check the Organization

Review the company name, address, country, facility, and available entity information. Determine whether the organization is a manufacturer, distributor, repair facility, or another supplier.

The facility location matters because one company can have different identifiers for different locations.

Compare Part Information

Compare the organization information with the manufacturer name, part number, NSN, description, and technical details.

Similar part numbers can have different revisions, materials, dimensions, or configurations. The supplier identifier should therefore be reviewed together with the complete part information.

Review the Record

Check the available entity status and other record details. An active organization record does not mean that a particular component is in stock, certified, or approved for your application.

CAGE Code, NSN, and Part Number

These identifiers have different purposes:

  • CAGE Code: Identifies an organization or facility.
  • NSN: Identifies a standardized supply item.
  • Manufacturer Part Number (MPN): Identifies a product according to the manufacturer's numbering system.

They are often used together in aerospace procurement. One NSN may be associated with multiple manufacturers or sources, and each source can have a different entity identifier and part number.

A buyer may start with an NSN and use the organization identifier to research a source. Alternatively, a buyer may start with the identifier and research associated manufacturers or parts.

Does a CAGE Code Verify a Supplier?

No. This identifier supports entity identification, but it does not by itself verify:

  • Product authenticity
  • Part condition
  • Certification
  • Traceability
  • Inventory availability
  • Supplier authorization
  • Delivery performance
  • Approval for a specific aircraft or contract

If a requirement specifies an OEM, approved source, certification, traceability, or other documentation, verify those requirements separately before purchasing.

Find Aerospace Parts by CAGE Code

Aerospace Exchange helps buyers research aerospace, aviation, defense, MRO, electronic, and industrial components.

If you have a CAGE Code, manufacturer part number, NSN, NIIN, or manufacturer name, use the available information to research the part and potential sources.

For a specific sourcing requirement, submit an RFQ to Aerospace Exchange with the part number, identifier or NSN, quantity, condition, delivery requirements, and documentation needs. Complete requirements help the sourcing team understand your request and research potential pricing and availability.

Conclusion

A CAGE Code lookup can help aerospace buyers identify the organization or facility connected with a part or procurement record. When combined with a manufacturer name, part number, or NSN, it provides useful information for supplier and parts research.

The identifier should not be treated as proof of product quality, certification, authenticity, or availability. Always compare the organization information with the complete part and procurement requirements before purchasing.

Frequently Asked Questions

How do I find a company using a CAGE Code?

Enter the five-character identifier into an official search resource or an aerospace parts directory and review the associated organization and facility information.

What information can I find from this identifier?

It can help identify the organization or facility connected with a procurement record. Combined with an NSN or part number, it can support manufacturer and supplier research.

Can I search an NSN using a CAGE Code?

Yes. These identifiers can be used together when researching aerospace parts. The organization identifier identifies the source, while the NSN identifies the standardized supply item.

Why can one company have multiple CAGE Codes?

A company may have different codes when it operates multiple facilities or locations. Checking the facility information can help identify the correct source.

Can I use a CAGE Code when requesting an aerospace part?

Yes. Include it with the manufacturer part number, NSN or NIIN, quantity, condition, delivery requirements, and documentation needs when submitting an aerospace parts RFQ.
