Company Codes: What They Are & How to Find Yours

Company codes are short alphanumeric identifiers assigned to a business by a government agency, a stock exchange, or a private database to uniquely identify that company in a standardized system. You enter a company code when filing taxes, trading stocks, or submitting a payment to identify the business you are dealing with. The exact code you need depends entirely on the system you are using, so this article explains the most common ones and how to find them.

What a Company Code Is in Different Contexts

The term “company code” is a generic label, and its meaning changes depending on the context:

• Tax identification: In the U.S., the IRS uses an Employer Identification Number (EIN), a 9-digit number, to identify a business entity for tax purposes.
• Stock trading: Exchanges assign ticker symbols (e.g., AAPL for Apple Inc.) that identify a publicly traded company on that specific exchange.
• International payments: SWIFT/BIC codes (8 or 11 characters) identify a specific bank, not a company, but they are often required when paying a company in a foreign currency.
• Business registries: Many countries have national registries that assign a unique company number, such as the Companies House number in the UK or the CVR number in Denmark.
• Procurement and vendor systems: Large corporations and government agencies assign their own internal vendor codes to each supplier they do business with.

Because the term is so broad, the first step is always to identify which system you are working with.

Common Types of Company Codes

Here are the codes you are most likely to encounter, along with their typical format:

• EIN (Employer Identification Number): Format: 12-3456789. Used by the IRS for U.S. businesses. You can look up a company’s EIN on public records or ask the company directly.
• Ticker Symbol: 1-5 letters (sometimes with a period or hyphen). Used on stock exchanges. For example, GOOGL is Alphabet Inc. on NASDAQ.
• SWIFT/BIC: 8 or 11 characters, e.g., DEUTDEFF (Deutsche Bank). This identifies the bank, not the company, and is needed for international wire transfers.
• LEI (Legal Entity Identifier): A 20-character alphanumeric code that identifies a legal entity globally. It is required for many financial transactions and is searchable on the GLEIF website.
• DUNS Number: A 9-digit number assigned by Dun & Bradstreet to businesses worldwide, often used in B2B credit reporting and government contracting.
• National registry numbers: Each country has its own, e.g., Companies House number (UK), ABN (Australia), CVR (Denmark). These are usually public and searchable via the official registry.

How to Find a Company’s Code

The method depends on the type of code you need:

1. Ask the company directly: The simplest and most reliable way. The accounting or finance department will know their EIN, LEI, or vendor code.
2. Check official registries: For EINs, you can use the IRS’s tax-exempt organization search (for nonprofits) or request a Form W-9 from the company. For LEIs, use the GLEIF LEI search tool. For national registry numbers, visit the official government registry website.
3. Look at financial documents: Public companies list their ticker symbol on their investor relations page, and their LEI is often in their annual report.
4. Check invoices and contracts: A company’s own tax ID or registration number is usually printed on their invoice or contract.
5. Use a business database: Services like Bloomberg, Dun & Bradstreet, or government open-data portals can provide codes for registered businesses.

Why Accuracy Matters

Entering the wrong company code can cause serious problems:

• Tax filing errors: An incorrect EIN on a tax form can result in penalties or delayed refunds.
• Failed payments: A wrong SWIFT code can send a wire transfer to the wrong bank, and recovering funds is difficult and slow.
• Regulatory non-compliance: Financial institutions are required to verify LEIs; using an invalid one can block a transaction.
• Credit reporting mistakes: Mixing up DUNS numbers can merge two companies’ credit files, causing a lender to see incorrect data.

Company Code vs. Other Identifiers

It is easy to confuse company codes with other identifiers, but they serve different purposes:

• Company code vs. VAT number: A VAT number is used for tax on goods and services in the EU and other regions, while a company code (like an EIN) is a general business identifier. They are often different numbers.
• Company code vs. bank account number: The bank account number identifies the specific account, while the SWIFT code identifies the bank. Both are needed for transfers.
• Company code vs. employee ID: An employee ID is internal to a company and not used in external transactions.

Frequently Asked Questions

What is the difference between a company code and a tax ID?

A tax ID (like an EIN) is a specific type of company code used for tax purposes. Other company codes, like ticker symbols or LEIs, serve different functions, such as trading or financial reporting. The term “company code” is broader and can refer to any identifier.

Where do I find a company’s SWIFT code?

You can find a company’s SWIFT code by asking their finance department, checking their invoice, or using an online SWIFT/BIC lookup tool. Remember, the SWIFT code identifies the bank, not the company, so you need the bank where the company holds its account.

Is a company code the same as a registration number?

Not necessarily. A registration number is a type of company code assigned by a government registry. However, a company may have multiple codes: a registration number, a tax ID, a ticker symbol, etc. They are all “company codes” in a broad sense.

Can I use a company code to look up a company’s financial information?

Yes, for public companies, a ticker symbol will give you access to financial statements. For private companies, an LEI or national registry number can be used to access basic corporate information, but financial details may not be public.

What should I do if I enter the wrong company code?

If you entered the wrong code on a tax form, contact the tax authority immediately to correct it. For a wire transfer, contact your bank right away; they may be able to recall the funds if the transfer has not been completed. For other databases, contact the company or the registry to update your records.

Do all companies have a company code?

Every registered business has at least one government-issued identifier (like an EIN or registration number). However, not all companies have a ticker symbol (only publicly traded ones) or an LEI (which is voluntary for many firms).
