What is the EIN / TIN for my startup?
If you’ve forgotten your startup’s EIN or aren’t sure if you’ve obtained one, there are a few steps you can take.
You can check your address book on Clerky. If you or a team collaborator entered your startup’s EIN while completing the company formation checklist, you’ll be able to find your startup’s EIN stored in your address book.
If your startup’s EIN is not stored in your address book and you can’t find this information elsewhere, you can ask the IRS to search for your startup’s EIN. You can do this by calling the Business & Specialty Tax Line at 800-829-4933. See the IRS website for more detailed instructions and additional suggestions for locating a lost or misplaced EIN.
