Three numbers, three agencies
Asking for the wrong number is a common reason a search comes back empty.
| Number | Issued by | What it identifies |
|---|---|---|
| Federal EIN | Internal Revenue Service | Identifies the business for federal tax. It is the same number in every state. |
| File number | Idaho Secretary of State, Business Services Division | Identifies the entity's record in the state registry. |
| Idaho State Tax Commission permit or account number (such as a seller's permit) | Idaho State Tax Commission | The Tax Commission issues seller's permits and other tax permits and offers a permit validation page. These are separate from the Secretary of State file number and from the federal EIN issued by the IRS. |
