If you’re a small business owner, you have probably applied for an EIN from the Internal Revenue Service. This number is used when you file tax returns, and it identifies your business to interested parties. You’ll need to give the EIN to your banker when you open business accounts, to companies you contract with, or government offices if you apply for business licenses. If you lose the first EIN letter, you can get a 147C letter from the IRS. This is a different type of EIN verification.
Call the IRS at 1-800-829-0115 between the hours of 7 a.m. and 7 p.m in your local time zone.
Request a 147C letter when the IRS agent takes your call. There is no charge, and if you need it quickly, ask the agent to fax it to you. The agent will ask some security questions about your business to verify you can get the letter. You could be asked the name and address of the business, the type of business income tax form you file, your name, and your position with the company. You won't get the letter unless you correctly answer these questions.
Authorize another party to request a 147C letter if you don't want to get the 147C letter yourself. You'll have to complete Form 8821 or 2848 form, and this person must be able to answer security questions about your business. The forms are free on the IRS website. You must check the box on line 4 for your designated person to get the verification letter. This person must fax the form to the IRS, usually while she’s on the phone with the IRS agent.
