Replace your lost EIN confirmation letter.
The IRS sends your EIN confirmation letter, the CP-575, only once, and it will not print another. If you have lost it and a bank or vendor needs proof of your EIN, the replacement is a Letter 147C. It confirms the exact same number, name, and address the IRS has on file. We request it for you and get it back by fax or mail.
Proof of an EIN you already have.
Letter 147C, formally titled EIN Previously Assigned, is the IRS document that verifies an employer identification number that was issued to you before. It is not a new EIN and it does not change your number. It is simply the official replacement for the CP-575, the one-time confirmation letter the IRS mails when your EIN is first assigned. Because the IRS will not reprint the CP-575, the 147C is what you request when the original is lost. Banks, lenders, payroll providers, and state agencies accept the 147C and the CP-575 interchangeably, since both prove the same thing.
An official letter on IRS letterhead.
The 147C states your business name, EIN, and address exactly as the IRS holds them, signed and printed on IRS letterhead so third parties will accept it.
- Your EIN, confirmed. The same number the IRS assigned, printed on official letterhead as Letter 147C.
- Your name and address on file. The legal business name and address the IRS has, so you can spot anything that needs updating.
- Delivered by fax or mail. The IRS returns it by fax, often the same day, or by mail to the address on file, never by email.
- A clean copy for your records. Ready to hand to a bank, lender, or agency that asks for proof of your EIN.
When someone asks for proof of your EIN.
You need a 147C when you have to prove your EIN but cannot find the original letter. If you still have the CP-575, you do not need one.
- You lost or never received the original CP-575 confirmation letter
- A bank or lender needs written proof of your EIN to open an account or fund a loan
- A payroll provider, vendor, or state agency asks for an IRS EIN letter
- Your records show the EIN but you have no official document to back it up
- You still have your original CP-575, which is equally accepted
- You never had an EIN and need to apply, which is getting an EIN
- Your responsible party or address changed, which is a Form 8822-B update
- You are closing the business and its IRS account, which is an EIN closure
A 147C confirms your number; it does not fix outdated details. If your name or address has changed, we can file a Form 8822-B at the same time.
How the IRS issues it.
These points are verified against current IRS guidance. The 147C is free, comes only from the IRS, and is delivered securely rather than by email.
IRS phone numbers and procedures can change. We confirm the current process before we request your letter.

Is a 147C a new EIN?
No. A 147C only confirms the EIN you already have; it never changes your number. If you have never had an EIN, you need to apply for one instead, which produces a brand-new number.
Why not just get another CP-575?
The IRS issues the CP-575 only once, when your EIN is first assigned, and will not reprint it. The 147C is the official replacement, and banks and agencies accept it exactly the same way.
How much does it cost and how long does it take?
The IRS charges nothing for the letter. It can come back by fax during the request, or by mail to the address on file in about four to six weeks. It is never emailed, for security.
Can you request it for me?
Yes, with your authorization. The IRS requires a third-party authorization such as Form 2848 or Form 8821 for us to request the letter on your behalf, which we prepare with you.
My address or responsible party changed. Does the 147C fix that?
No. The 147C shows the details the IRS currently has. To update a changed address or responsible party, you file a Form 8822-B, and if you are closing the business entirely, that is an EIN closure, both of which we can handle at the same time.
