What Is a CP 575? IRS EIN Confirmation Letter (2026)

You applied for an EIN, and a few weeks later a CP 575 lands in your mailbox or download folder. It's one page, easy to file away and forget, and the only original the IRS will ever send you. That matters the first time a bank asks you to prove the number is yours. Need pay records meanwhile? Our pay stub creator covers that.

Below you'll find what the IRS CP 575 is, what's on it, who asks for it, your 2026 options if yours is missing, how it stacks up against the 147C letter, and what the lettered versions mean.

Key Takeaways

• A CP 575 is the IRS notice that confirms your EIN, your legal business name, and your filing address.
• The IRS issues it one time only, and it will not print a second original.
• Banks, lenders, state tax agencies, and payroll providers all accept it as proof of your EIN.
• Since July 2026, eligible businesses can download a digital CP575 notice from an IRS Business Tax Account instead of waiting on a 147C letter.

What Is a CP 575?

A CP 575 is the notice the IRS issues after it approves your EIN application, so it's also called the EIN confirmation letter. It confirms your nine-digit Employer Identification Number, legal business name, and filing address. You receive it once, and you can't fill one out yourself.

The same document goes by the CP-575 letter, the CP 575 form letter, the EIN letter, or simply CP575; the hyphen changes nothing. Some owners call it the CP575 IRS form, which causes a mix-up: no blank version exists, because the IRS writes the notice for you once your application clears.

What's on a CP 575 Letter?

The letter lists six things: your nine-digit EIN, your legal business name, the mailing address on file, the date the IRS assigned the number, the federal tax forms your business must file, such as Form 941 or Form 940, and their filing due dates.

Officially it's IRS notice letter CP 575, and every detail stays valid for the life of the business. Most requesters only want the number, exact legal name, and address, so keep those three handy.

Who Asks for Your CP 575 EIN Confirmation Letter?

Banks ask for a CP 575 EIN confirmation letter before opening a business account, lenders request it for loans and credit lines, states want it for payroll tax registration, and payroll providers need it to verify your legal name and EIN before your first payday. Clients sometimes ask self-employed contractors for it too.

Hiring your first employee? Hand your payroll provider the notice itself. Providers match the legal name and EIN against IRS records before releasing direct deposit, and a mismatch delays payday. That EIN then shows up in Box b of every W-2 and on each pay stub you issue.

Self-employed readers field these too. A lender, landlord, or new client may want EIN proof from a single-member LLC.

How Do You Get a CP 575 From the IRS?

Apply for an EIN with Form SS-4, and the IRS issues the CP 575 automatically. Applying online gives you a digital notice at the end of the session. Faxing Form SS-4 returns your EIN in about four business days, and mailing it takes about four weeks.

You never have to request IRS Form CP 575 separately. It follows approval on its own:

An IRS notice CP 575 only goes out at assignment, so there's no annual reissue. Waiting on the mail? Our pay stub templates keep payroll moving.

Lost Your CP 575? Here Are Your 2026 Options

The IRS won't reprint the original CP 575, but you have two replacements in 2026. Designated officials can download a digital CP575 notice from an IRS Business Tax Account, per IRS Fact Sheet FS-2026-11. Everyone else can call the Business and Specialty Tax Line at 1-800-829-4933 and request a 147C letter by mail or fax.

Fact Sheet FS-2026-11, published July 2026, added this option to the IRS Business Tax Account. Sole proprietors with an EIN, partnerships, S and C corporations, tax-exempt organizations, and government entities can open an account. Single-member LLCs taxed as sole proprietors are still waiting on access, so the phone route is their fallback.

Request a 147C Letter by Phone

Call 1-800-829-4933, Monday through Friday, 7 a.m. to 7 p.m. local time, and ask for a 147C. It arrives by mail or fax only, never email. Check three places first: your online application email, your business bank file, and any 941 or W-2 you've filed.

CP 575 vs. 147C Letter

The difference is timing: one confirms a new EIN, the other verifies an existing one. Banks take either, so hand over whichever you have.

What CP 575 A, CP 575 B, and CP 575 G Mean

The suffix identifies which version of the paper series the IRS printed, and that series runs from CP 575 A through J. A CP 575 A, a CP 575 B, and a CP 575 G confirm the same facts: your EIN, your legal name, and the returns you owe. The IRS treats the new digital download as a substitute for the whole lettered series, so whichever CP 575 IRS notice you hold is equally official at a bank.

Keeping Your CP 575 Safe and Accurate

Scan the CP575 letter the day it arrives, save the PDF to cloud storage, and keep the paper copy separate. Copy the number from that scan rather than typing from memory, since one transposed digit is a common reason e-filed payroll returns bounce back.

If your business address or responsible party changes, file Form 8822-B within 60 days so your IRS CP-575 details still match what your bank and payroll system hold. A legal name change works differently: you report that on your next return or in a signed letter to the IRS, not on Form 8822-B. The IRS employer identification number page covers the rest.
