Three numbers, three agencies
Asking for the wrong number is a common reason a search comes back empty.

|---|---|---|
| Federal EIN | Internal Revenue Service | Identifies the business for federal tax. It is the same number in every state. |
| Filing number | Oklahoma Secretary of State, Business Filing Department | Identifies the entity's record in the state registry. |
| Oklahoma Tax Commission account (OkTAP) | Oklahoma Tax Commission | Sales tax permits and other state tax accounts are issued by the Tax Commission through OkTAP and are separate from the federal EIN and the Secretary of State filing number. |
