If you need to find your Employer Identification Number (EIN) to complete your Mercury application (or for any other reason), there are a couple of places you can look.
- Check for any IRS letters or notifications you received in the mail. These will usually include your EIN number.
- If you used your EIN to get a business license or permit with a state agency, you can contact them and ask them to provide the number.
- You can call the IRS directly. The Business & Specialty Tax Line is 800-829-4933 and is open Monday through Friday, 7 am to 7 pm Eastern Standard Time. An IRS rep will ask you some questions to confirm you’re the business owner.
After account approval
Once your account is approved, beneficial owners can view the EIN on file from the Company Profile page.
If your EIN has changed, a beneficial owner must contact our team for review. A specialized team will ask why it changed, whether other aspects of the business have changed, and whether the company was dissolved. We may also request supporting documentation before determining the next steps.
