What Is a CAGE Code and Why Businesses Have Them

A CAGE Code is a unique identifier number assigned to businesses that do work with the federal government. CAGE stands for Commercial and Government Entity Code. The federal government created this system to track which companies supply goods and services to government agencies. Every business that wants to sell products or services to any U.S. federal agency needs a CAGE Code.

The CAGE Code system operates through the System for Award Management (SAM), which is a free database run by the federal government. When a business registers in SAM and receives a CAGE Code, that information becomes public record. Other businesses, government contractors, and the general public can look up any CAGE Code to see company details and history.

CAGE Codes are five characters long and consist of letters and numbers. For example, a CAGE Code might look like: 1A2B3 or ABC45. The code itself doesn't tell you anything about the company—it's simply a reference number. The real information comes from looking up that code in the SAM database and seeing what details the company entered about itself.

Businesses need CAGE Codes for several reasons. First, any company bidding on federal contracts must have a CAGE Code. Second, if a company works as a subcontractor to another business that has federal contracts, the subcontractor often needs a CAGE Code too. Third, some federal agencies won't do business with a company unless it's registered in SAM with a active CAGE Code. Finally, having a CAGE Code allows your business to be searchable in federal databases, which can lead to government buyers finding you.

The CAGE Code system has been in use since the 1960s. It was originally created by the Department of Defense, but now all federal agencies use it. Over time, the government modernized the system and combined it with other registration requirements into SAM. Today, SAM is the single official database for all federal contractor and vendor information.

Practical Takeaway: Understanding what a CAGE Code is helps you know whether your business needs one. If your company sells to, works for, or wants to bid on contracts with any federal agency, you need a CAGE Code in the SAM system.

How to Find CAGE Code Information Online

Finding CAGE Code information about a specific business is completely free and requires no registration. The primary tool for this is the SAM database search function at sam.gov. This website allows anyone to search for any registered business using multiple methods.

The easiest way to search is using the company name. Go to sam.gov and use the main search box. Type in the full business name or part of it if you're not sure of the exact spelling. The system will return results showing all registered businesses with that name or similar names. Each result displays the CAGE Code, the business address, the state, and other basic details. This search method works well when you know the company name but not the CAGE Code.

You can also search by CAGE Code directly if you already have the number. This is useful when you've found a CAGE Code reference somewhere else—like on a contract or invoice—and want to look up details about that company. Simply enter the five-character code in the search field, and SAM will return the exact business information linked to that code.

Another search option is looking by business address or location. If you know where a company is located but not its name or CAGE Code, you can search by city, state, or ZIP code. This returns all businesses registered from that location. This method helps when you're trying to find competitors or vendors in a specific area.

The SAM database also allows searches by DUNS Number, which is a different business identifier issued by the company Dun & Bradstreet. Many businesses have both a CAGE Code and a DUNS Number. If you know a company's DUNS Number, you can enter it to find that business's CAGE Code and other registration details.

When you view a business's full SAM record, you'll see information such as the official business name, DBA (doing business as) names if any, mailing address, physical address, contact person, phone number, email, the date the business registered, and the current status of the registration. You may also see details about whether the business is a small business, minority-owned, woman-owned, veteran-owned, or other classifications.

Practical Takeaway: Use sam.gov to search for any registered business's CAGE Code and details. You need no account, password, or fee. The information is public and available to anyone who searches.

Understanding CAGE Code Registration and Requirements

Any business that wants to do work with the federal government must first register in SAM and receive a CAGE Code. However, the registration process and requirements vary depending on the type of business and the kind of work involved. Understanding these requirements helps you know what information you'll need to gather if your business registers.

The first requirement is that your business must have a valid Tax Identification Number (TIN). For sole proprietors, this is typically a Social Security Number (SSN). For partnerships and corporations, it's an Employer Identification Number (EIN) issued by the Internal Revenue Service (IRS). The federal government uses your TIN to verify that your business is real and legally registered with the IRS.

Your business must also have a physical business address. You cannot register with only a mailbox address or virtual office address. The federal government requires a real location where your business operates or conducts its main activities. This address is used for official correspondence and verification purposes.

If your business has employees, you must have completed a workers' compensation insurance form, often called the I-9 Employment Eligibility Verification form. This documents that your employees are legally allowed to work in the United States. Even if you're a sole proprietor with no employees, you should be prepared to provide this information.

You must designate at least one Point of Contact (POC) for your business registration. This is the person who will receive official communications from the federal government regarding your registration and any contracts or payments. Many businesses designate their owner, manager, or administrative person as the POC. You must provide this person's full name, title, email address, and phone number.

Your business needs to declare its North American Industry Classification System (NAICS) code. NAICS codes are standardized numbers that describe what type of business you operate—for example, 541330 is engineering services, and 238210 is electrical contractors. The federal government uses NAICS codes to organize businesses by industry. You can look up your business's NAICS code on the NAICS website or by describing your business activities to the federal registration system.

Businesses that will have contracts over a certain amount (currently $25,000 or more per year) must register for a DUNS Number if they don't already have one. The DUNS Number comes from Dun & Bradstreet and provides additional business verification. Smaller contracts may not require a DUNS Number, but many government agencies prefer working with businesses that have one.

Practical Takeaway: Before registering for a CAGE Code, gather your Tax ID, business address, NAICS code, and information about your principal contact person. These are the core pieces of information you'll need.

What Information Appears in a Public CAGE Code Record

When you look up a business's CAGE Code information on SAM, you'll see a standardized set of data. Understanding what each piece of information means helps you read and interpret CAGE records correctly. This information is public and available to anyone, including competitors, customers, and the media.

The CAGE Code itself appears at the top of the record—a five-character alphanumeric code. Below that is the official business name as registered with the government. This is the legal name of the business, which may be different from any "doing business as" names the company uses with customers. Many businesses register under their full legal name but operate under a shorter or more casual name in public.

The record shows the business address in two formats: mailing address and physical address. The mailing address is where official government correspondence will be sent. The physical address is the actual location where the business operates. Sometimes these are different—for example, a business might have its mail delivered to a downtown office but operate from a warehouse in another location.

SAM records include the business's activation date, which shows when the company first registered in the system. This is useful historical information
