If you previously applied and received an Employer Identification Number (EIN) for your business, but have since misplaced it, try any or all of the following actions to locate the number:
- Find the computer-generated notice that was issued by the IRS when you applied for your EIN. This notice is published as a confirmation of your application, and receipt of an EIN.
- If you used your EIN to open a bank account or apply for any state or local license, you should contact the bank or agency to secure your EIN.
- Find a previously filed tax return from your existing entity (if you have recorded a profit) for which you have your lost or misplaced EIN. Your previously filed return should be notated with your EIN.
- Ask the IRS to search for your EIN by calling the Business & Specialty Tax Line at 800-829-4933. The hours of operation are 7:00 a.m. – 7:00 p.m. local time, Monday through Friday. A facilitator will ask you for identifying information and provide the number to you over the telephone, as long as you are a person who is authorized to receive it. Examples of an authorized person include, but are not limited to, a sole proprietor, a partner in a partnership, a corporate officer, a trustee of a trust, or an executor of an estate.
