Form 147C
Form 147c is a document issued by the Internal Revenue Service (IRS) in the United States. It is also known as the EIN Verification Letter.
What is Form 147C?
Form 147C, more accurately an EIN Verification Letter issued by the IRS, confirms a business’s previously assigned Employer Identification Number when the original confirmation notice has been lost.
Why does Form 147C matter?
Banks, payroll providers, and other institutions often require proof of a business’s EIN, and a 147C letter is the standard way to obtain that proof when the original EIN confirmation letter (the CP 575) is no longer available.
How does Form 147C work?
A business calls the IRS Business & Specialty Tax Line, verifies its identity, and requests a 147C letter, which the IRS provides by fax or mail confirming the entity’s legal name and EIN.
Frequently asked questions
Is a 147C letter the same as the original EIN confirmation?
No, the original confirmation is the CP 575, issued only once when the EIN is first assigned; a 147C letter is a replacement verification issued afterward on request.
Can a 147C letter be requested online?
No, it generally must be requested by phone through the IRS Business & Specialty Tax Line.
