Selling to the U.S. federal government requires registration on SAM.gov, which means obtaining either a CAGE or an NCAGE code. Pick the wrong one, or mismatch it with your company records, and you risk duplicate codes, validation delays, and a stalled registration. Fortunately, the rule is simple: the right code depends on where your legal entity is located, not on where your customers are or who owns you.
In this blog, we break down the difference between the two codes, how to determine which route applies to your business, and the most common mistakes that delay or block federal registration.
CAGE vs. NCAGE at a Glance
| CAGE | NCAGE | |
|---|---|---|
| Stands for | Commercial and Government Entity | NATO Commercial and Government Entity |
| Who it’s for | Entities in the U.S. or its outlying areas | Entities outside the U.S. or its outlying areas |
| Managed by | Defense Logistics Agency (DLA) | NATO Codification System, via a National Codification Bureau or NSPA |
| Typical starting point | SAM.gov registration | NCAGE request first, then SAM.gov |
| How it’s issued | Assigned by DLA during SAM.gov registration | Assigned by a National Codification Bureau or NSPA |
Both codes identify an organization at a specific location. However, neither one:
- Activates your SAM.gov registration
- Replaces your Unique Entity ID (UEI), the 12-character identifier SAM.gov assigns after validating your legal name and physical address
- Establishes award eligibility
- Proves small-business status
You can look up existing CAGE codes through the DLA CAGE code search tool. For NCAGE, search through the NATO Codification System before applying.
Which One Do You Need?
Ask one question first: Where is the exact legal entity that will sign the contract, receive payment, and take responsibility for performance?
Located in the U.S.: You Need a CAGE Code
This route applies to U.S. companies, government organizations, U.S.-based schools and nonprofits, and domestic manufacturers, distributors, and service providers.
Importantly, foreign ownership does not change this. A company formed and genuinely operating in the United States follows the domestic CAGE route even if its parent is overseas. That said, it must still disclose its ownership and control relationships. Specifically, the Federal Acquisition Regulation (FAR) requires offerors owned or controlled by another organization to report that owner. Review the applicable disclosure requirements at FAR 52.204-17.
Registration path:
- Start in SAM.gov. It validates your legal name and physical address, then issues your UEI.
- Next, complete the remaining registration sections.
- An existing CAGE may match to your record. If none exists, DLA assigns one through the workflow.
- Finally, respond to any DLA requests for supporting information.
Note: creating a SAM.gov user account only gives you system access. Registering the entity is what lets you pursue contracts.
Located Outside the U.S.: You Need an NCAGE Code First
This route applies to foreign manufacturers and suppliers, international service providers, overseas nonprofits and schools, and foreign entities in defense, logistics, or NATO-related procurement.
Registration path:
- First, confirm your exact legal name and physical address.
- Then, search for an existing NCAGE. A code may already exist under a previous name, former address, or predecessor company.
- Next, apply through your country’s National Codification Bureau (for NATO members and sponsored nations) or through the NATO Support and Procurement Agency (NSPA) for other countries. Portals and forms differ by country.
- After that, verify the NCAGE record is accurate and searchable.
- Then begin SAM.gov registration using the same name and address as the NCAGE record.
- Finally, get your UEI, complete the remaining sections, and provide foreign banking, tax, and ownership information.
A U.S. Office Does Not Make a Foreign Company Domestic
A foreign company does not become a U.S. entity simply because it has any of the following:
- A U.S. mailing address
- A registered agent
- A virtual office or commercial mailbox
- A U.S. phone number
- A salesperson in the U.S.
- A short-term coworking space
In each of these cases, the company keeps its foreign legal identity. That means its foreign name, foreign location, NCAGE, and foreign registration and tax documents still apply.
The U.S. Subsidiary Alternative
However, there is an alternative. If a foreign parent forms a separate U.S. subsidiary, that subsidiary can follow the domestic CAGE route. To do so, it must meet all of the following:
- Legally formed in the U.S. and legally distinct from the parent
- Tied to a legitimate U.S. physical location
- Properly registered and active
- Assigned its own tax ID, with its own bank account and records
- Accurately reporting its immediate and ultimate owners
Furthermore, the parent and subsidiary must never share or swap identifiers. Each needs its own legal-name validation, address, UEI, CAGE or NCAGE, tax information, bank account, SAM.gov registration, and representations and certifications.
Foreign ownership does not block a U.S. subsidiary from registering. Nevertheless, it can affect eligibility for certain set-asides, security-sensitive contracts, export-controlled work, and facility clearances. For guidance on the implications of foreign ownership, control, and influence, refer to DCSA’s FOCI resources.
The Golden Rule: Match the Name and Location
The FAR requires the code on your offer to correspond to the offeror’s name and location address. As a result, never do any of the following:
- Use a parent’s code for a subsidiary
- Borrow a sister company’s NCAGE
- Use a headquarters code for an unrelated legal entity
- Keep using an old code tied to a former address
- Treat a registered agent’s address as your operating location
- Choose an overseas office just because its application route looks easier
Moreover, different locations of the same organization can carry different codes. Contractors must maintain CAGE information throughout the life of every contract. Review FAR 4.1800 for the full regulatory basis.
Which Physical Address Should You Use?
Use the genuine location of the legal entity being registered. In most cases, headquarters is the safest choice. It should appear consistently across your incorporation, tax, banking, licensing, and occupancy records.
A branch or regional office also works, provided it belongs to the same legal entity, operates at a real location, is registered where required, and can be documented.
A P.O. Box cannot serve as your physical address in SAM.gov. You can list a separate mailing address. Be ready to support the physical one with records such as:
- Formation or registration documents
- Business license
- Lease or occupancy agreement
- Utility bill
- Bank or tax records
- Insurance documents
- Payroll or employee-location evidence
Where the UEI Fits In
Your UEI is a 12-character ID that SAM.gov assigns after validating your legal name and physical address. It is separate from your CAGE or NCAGE code. The FAR treats them as distinct identifiers.
Therefore, an organization holds a UEI plus either a CAGE (if U.S.-located) or an NCAGE (if foreign-located).
You can request a UEI without completing a full registration. However, a UEI-only record will not let you bid directly on federal contracts or apply for awards that require an active registration. For a full explanation, the SAM.gov Help Center provides current guidance on entity registration and UEI issuance.

10 Common Mistakes
- Legal-name mismatches. The SAM.gov name does not match your formation documents, tax records, bank account, or CAGE/NCAGE record.
- Address inconsistencies. Building numbers, suite numbers, postal codes, transliterations, and abbreviations vary across documents.
- Mailing address as physical address. P.O. boxes, mail-forwarding services, and commercial mailboxes are not accepted.
- Registered agent’s office as your location. The agent accepts legal notices. That address is not automatically your place of business.
- Requesting the wrong code. Wanting U.S. contracts does not make you a domestic entity. Your own location decides the route.
- Confusing subsidiary and parent. They are separate legal entities, each requiring its own identifiers and records.
- Assuming the code activates SAM.gov. You still need to finish all registration sections and pass federal review.
- Creating duplicate records. Always check the DLA CAGE search tool for an existing code before requesting a new one.
- Skipping ownership disclosure. A company can be U.S.-formed and foreign-owned. Those are not contradictory, but you must report your immediate and highest-level owners under FAR 52.204-17.
- Updating only one system. When your name or address changes, update SAM.gov, CAGE/NCAGE, banking, tax, and licensing records together. In addition, foreign applicants should settle on one consistent version of the company name before starting. Differences in punctuation, transliteration, legal suffixes, or postal details can break matching and validation.
Pre-Registration Checklist
Gather these before you begin:
- Formation or incorporation documents
- Exact legal business name and suffix
- Verified physical address and mailing address if different
- Taxpayer or national ID number
- Banking information
- Business license
- Immediate-owner and highest-level-owner information
- Authorized representatives and points of contact
- Any existing CAGE, NCAGE, or UEI records — check cage.dla.mil
- English translations or transliterations for foreign entities
- Documents supporting recent name or address changes
- Lease or occupancy evidence
- Intercompany documents if a foreign parent and a U.S. subsidiary are involved
Above all, consistency is the most important habit. Your legal name and physical address should be consistent across formation documents, tax records, banking information, CAGE/NCAGE data, and SAM.gov.
The Bottom Line
- CAGE is for entities located in the United States or its outlying areas.
- NCAGE is for entities located outside the United States or its outlying areas.
Choosing the right code is only one step. Beyond that, you also need to verify the correct legal entity, document its physical location, obtain a UEI, complete the SAM.gov sections, accurately disclose ownership, and maintain the record after activation.
For foreign companies eyeing the U.S. federal market, the central question is whether the foreign company itself will pursue federal work or a separately formed U.S. subsidiary will. That choice shapes the code route, tax and banking records, ownership disclosures, responsibility for performance, and the government record under which awards are administered. As a result, aligning the entity, location, ownership, and identifiers from the start avoids costly delays later.
