Can I use my DUNS number instead of my EIN number?

Answered by Randy McIntyre

While a DUNS number and an EIN (Employer Identification Number) are both unique identification numbers, they serve different purposes and cannot be used interchangeably. A DUNS number is issued by Dun & Bradstreet and is primarily used to identify businesses for credit reporting and business-to-business transactions. On the other hand, an EIN is issued by the Internal Revenue Service (IRS) and is used for tax purposes, including filing tax returns and reporting business income.

It is important to note that a DUNS number is not a replacement for an EIN or a Social Security Number (SSN) when it comes to lending and application purposes. Lenders and financial institutions typically require either an EIN or an SSN to evaluate creditworthiness and verify the identity of an individual or business.

If you are a sole proprietorship or a single-member LLC, you may use your SSN as your business identification number. However, if you have employees, are required to file employment tax returns, or operate as a partnership or corporation, you must obtain an EIN from the IRS. The EIN serves as the primary identification number for these types of entities.

Using a DUNS number instead of an EIN or SSN can lead to complications and may not be accepted by lenders or other institutions. Therefore, it is important to ensure that you have the appropriate identification number for the purpose at hand.

For example, when applying for business loans or credit, lenders typically require an EIN or SSN to conduct credit checks and verify your financial history. Using a DUNS number in place of an EIN or SSN may result in delays or even denial of credit.

In my personal experience, I have encountered situations where clients mistakenly provided their DUNS number instead of their EIN or SSN when applying for loans or credit. This caused significant delays in the application process, as the lenders required the correct identification number to proceed with the evaluation.

To summarize, a DUNS number should not be used as a substitute for an EIN or SSN for lending and application purposes. It is essential to have the appropriate identification number to avoid complications and ensure a smooth process when dealing with financial institutions and lenders.
