How do I verify a resale number is valid and active?

Account ID, FEIN, resale, and License Numbers can be verified at MyTax Illinois by selecting Business at the top of the page and then selecting the Verify a Registered Business link. This system allows you to inquire whether a business is registered with the Illinois Department of Revenue and how that business is registered with IDOR.

If you have additional inquiries, you may submit them to the Questions, Comments, or Request form.
