What Is a 147c Letter?
A 147c letter, commonly known as an EIN letter, is a request sent to the Internal Revenue Service (IRS) to verify a company’s Employee Identification Number (EIN) or grant permission to a third party to do so. It does not create an EIN number.
To obtain a 147c letter, contact the IRS Business and Specialty Tax line at 1-800-829-4933, Monday through Friday from 7:00 AM to 7:00 PM in taxpayer local time (Alaska and Hawaii follow Pacific Time). The caller will be required to answer several security questions prior to receiving the letter, which will be mailed or faxed.
If you need to locate your EIN number, there are alternative options that you can pursue before requesting a 147c letter from the IRS.
