If you applied for and received a taxpayer identification number for your trust or an employer identification number for your business but have since misplaced it, try the following actions to locate the number:
• If you used your EIN to open a bank account, or apply for any type of state or local license, you should contact the bank or agency to get 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. – 10:00 p.m. local time, Monday through Friday. An assistor 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.
• Find the computer-generated notice that was issued by the IRS when you applied for your EIN. This notice is issued as a confirmation of your application for, and receipt of an EIN.
