Your EIN is included on any federal tax return you have filed. Reviewing copies of these returns can help you locate your EIN.
3. Contact Your Bank
If you have opened a business bank account, your bank will have your EIN on file. Contacting your bank and requesting this information can be a quick solution.
4. Check Official Business Documents
Look through your business’s official documents, such as loan applications, business licenses, or permits, where your EIN might be listed.
