How to Open a Business Credit File and Build Credit History


By opening credit files at major business credit bureaus or having tradelines that report payment history, you can establish business credit. As you try to establish business credit with vendors and suppliers they will then access your business credit reports to determine whether your application gets approved.

How to Open

As a new business owner, your very first step to establishing business credit will be opening credit files at Dun & Bradstreet, Experian, and Equifax. Before you build business credit, you’ll have to register a legal business entity and apply for an EIN and a DUNS number that will both be linked to it.

Business Entity

A legal business entity is required to open a business credit file, and a sole proprietorship or DBA (doing business as) company will only get you so far. To remove all personal liability from doing business you’ll need a state-registered Limited liability Company (LLC) or a Corporation. When selecting either you’ll also ensure you are eligible for many different tax credits that are not available for sole proprietors.

Most small businesses can simply register an LLC while obtaining any industry-specific licenses they need to do business from their local state or municipal government. If you need to operate as a non-profit, or foresee future business expansion that includes having several branches or shareholders, then registering a C Corp or S Corp would be better.

SIC Codes

No matter if you choose an LLC or corporation, be sure to avoid high-risk SIC codes when registering your business. A low-risk SIC code with set you up to start building business credit quickly, whereas a high-risk code will cause you to require collateral assets to get business loans in the future.


Your EIN is a business Tax ID number issued by the Internal Revenue Services. that you can quickly apply for free on the IRS website, or by sending in your application via email or fax. You will need your EIN when opening a business credit file or a business bank account, as well as when filing your taxes.

Just like an SSN is used to gather credit data for personal credit reports an Employer Identification Number is an equivalent used to gather financial data for a business credit report.

DUNS Number

This nine-digit number is a unique business identifier linked to your Dun & Bradstreet business credit bureau file. While a applying for D-U-N-S number is not compulsory to conduct business, you’ll need it to generate the D&B Ratings which many vendors use to judge your creditworthiness.

Providing your DUNS on tradeline applications will allow your vendor to report your payment history. You can apply for a DUNS number for free on, but you might have to wait up business 30 business days to receive it. Unfortunately, the only way to speed up the process is to pay extra for their 5-day express service.

Bank Account

While it’s not mandatory to have a bank account to open a business credit file, it’s will be needed once you move past net 30 accounts for new businesses. Many credit suppliers will require you to have a business bank account to apply, and it is no longer compulsory when applying for a business loan.

You can easily apply online for a free business checking account at many different banks, which have very low or no minimum deposit requirements. So if you want to easily build business credit by purchasing office supplies, just make sure you get your banking details in order.

Credit Bureaus

To start building business credit you’ll need open credit files at the major business credit bureaus at Dun & Bradstreet, Experian, and Equifax. Most bureaus will require you to use vendors and suppliers who report positive payments to add business financials to your credit profile.

Next Steps
