If you’ve lost or never received your IRS EIN confirmation letter, you may be asking: how do I get a copy of my IRS EIN confirmation letter? This document—also known as the CP 575 notice—is crucial for many business activities like opening a bank account, applying for licenses, or verifying your EIN.
In this guide, you’ll learn what the confirmation letter is, how to request a copy, and what to do if you applied online or years ago.
What Is an IRS EIN Confirmation Letter?
The EIN Confirmation Letter (IRS Notice CP 575) is the official document the IRS issues when it assigns an Employer Identification Number (EIN) to a business or entity. It includes:
- Your official EIN
- Business name and address
- Date of issuance
- Tax classification
You usually receive this letter shortly after applying for an EIN, either online, by mail, or fax.
Why You May Need a Copy
You may need your EIN confirmation letter for:
- Opening a business bank account
- Applying for business credit or loans
- Registering your business with state or local agencies
- Filing for tax-exempt status (nonprofits)
- Verifying your EIN with clients or vendors
How Do I Get a Copy of My IRS EIN Confirmation Letter?
If you’ve lost your original CP 575 letter or never downloaded it, here’s how to get a copy:
1. Call the IRS Business & Specialty Tax Line
This is the most direct method.
- Phone: 1-800-829-4933
- Hours: Monday–Friday, 7 a.m. to 7 p.m. (local time)
- Who can call: Only an authorized person listed on IRS records (such as the business owner)
Ask the IRS to send you a 147C Letter — this is the official IRS replacement for a lost EIN confirmation letter.
Note: The IRS will not send CP 575 again, but the 147C letter is equally valid for banks, licensing, and tax purposes.
2. Check Your Records
Before calling the IRS, check these places where your original EIN may appear:
- Email confirmation if you applied online
- Download folder or printed copy of the PDF (if saved)
- Business tax returns
- Business license applications
- Bank documents
- Accountant or attorney files
3. Ask Your Registered Agent or Tax Professional
If you used a registered agent service or business formation company, they may have a copy of your EIN letter on file.
Can I Get the Confirmation Letter Online?
No. If you didn’t download the EIN confirmation letter when applying online, the IRS does not allow re-downloading. You’ll need to call and request a 147C letter by mail or fax.
What Is the 147C Letter?
The IRS 147C Letter is the official alternative to the original EIN confirmation letter. It contains the same EIN details and can be used for all legal, financial, and business purposes.
You can request to receive it by mail or fax after verifying your identity over the phone.
