How to get a replacement EIN confirmation letter
Call the IRS. Contact the
IRS Business & Specialty Tax Line
at 1-800-829-4933. The line is open Monday through Friday, 7 a.m. to 7 p.m. local time.
Request a 147C letter. When you speak with an agent, explain that you need a replacement EIN verification letter, which is formally called a 147C letter.
Confirm your identity. You must be an authorized person, such as a sole proprietor, partner, or corporate officer, to request this information. The agent will ask you a series of security questions to verify your identity and your relationship to the business.
Choose your delivery method. The IRS can either mail or fax the letter to you. Faxing is the fastest option, as a mailed letter can take several weeks to arrive.
