DUNS Number vs EIN: What Is the Difference?

Search intent

Searchers ask whether EIN and DUNS are the same thing.

They are not the same

An EIN comes from the IRS and is used for tax and business identification. A DUNS number is associated with Dun & Bradstreet and may be used by vendors or creditors to identify a business profile. Most serious business credit builders eventually need to understand both.

Which comes first

Set up the business entity and EIN first. Then make sure the business identity is consistent before working on bureau profiles. If the name, address, or phone is inconsistent, bureau records can become fragmented.

Why it matters

Credit reporting depends on matching the right business to the right records. If a vendor reports to the wrong or incomplete profile, the activity may not help the company the way you expected.
