The CP 575 is the IRS's one-time notice confirming your Employer Identification Number (EIN). The IRS issues it once and does not reissue the original, so if you lost it you request Letter 147C, which proves the same EIN.
The IRS assigns your EIN and confirms it with a single CP 575, which it will not duplicate or recreate.
Letter 147C (EIN Previously Assigned) is the IRS's official substitute and proves the exact same number.
The online EIN tool rejects applicants with no US presence, so your CP 575 follows a mailed or faxed Form SS-4.
What is the CP 575?
The CP 575 is the IRS notice that confirms your Employer Identification Number. The IRS describes the current version as a digital notice that confirms your Employer Identification Number. Historically, it is the one-time paper confirmation the IRS mails after it assigns your EIN. Either way, it is the document that officially ties your nine-digit number to your business name on the federal record.
For a US LLC, that EIN is the number your bank, your payment processor, and the IRS use to identify the business. The CP 575 is simply the proof that the number is yours. If you are not yet certain your LLC even needs one, our guide on whether your LLC needs an EIN is the place to start before the confirmation notice matters.
What the notice contains
The CP 575 is short, and knowing what to look for helps you recognize it, or tell an unrelated IRS letter apart from your EIN confirmation, when a bank or platform asks for it. Use this as a quick field map the next time you dig an old notice out of your files. It typically shows:
The notice label itself. The document is headed CP 575 and reads as a brief, computer-generated IRS notice confirming your EIN, not a form you filled in.
Your nine-digit EIN.
The legal name and business name on the IRS record.
The mailing address the IRS has on file for the entity.
The federal tax forms the IRS expects the entity to file.
The due dates tied to those forms.
None of this is sensitive to reproduce here, and it is worth checking each field for typos the moment the notice arrives. A misspelled legal name or a wrong address on the CP 575 is easier to correct early than after a bank has already keyed it into your file. Read the notice against your Form SS-4 and confirm the two agree. If the mailing address or responsible party on the IRS record is wrong or has since changed, you fix that with the IRS on Form 8822-B, not by editing the CP 575 itself.
How non-US founders actually get the CP 575
Here is the gap that trips up most founders outside the US. The IRS online EIN application is closed to you if you have no legal residence, principal place of business, or office or agency in the United States. The SS-4 instructions state this plainly, so a founder with no US footprint cannot generate an instant online EIN or its CP 575.
Instead, you apply on paper. You file Form SS-4 by fax or mail, and the CP 575 confirmation follows once the IRS assigns the number. If you have no SSN or ITIN and are ineligible to get one, the IRS tells you to enter "Foreign" or N/A on line 7b of the SS-4. You do not need a US tax ID to get an EIN, which is the key reassurance for this audience. Our step-by-step on the no-SSN EIN path walks through that form line by line.
On timing, the IRS publishes its own figures, and we treat those as the IRS's numbers to verify, not a CORPBOLT promise. The SS-4 instructions state that a faxed application generally returns the EIN within about four business days. A mailed one arrives in roughly four weeks. Both are the IRS's own stated timeframes, so check the current figure on the live IRS page before you plan around it.
Lost your CP 575? Request Letter 147C instead
If the original is gone, stop looking for a replacement CP 575. The IRS is direct about this: the original CP575A-J notice series, its Notice of New Employer Identification Number, cannot be duplicated or recreated. The letter suffix is just part of that series, so a notice labeled CP575A, CP575G, or any letter from A to J is the same kind of EIN confirmation. The IRS does not publish a separate meaning for each suffix, so for anything specific to your version, rely on the IRS CP575 guidance rather than a third-party interpretation. There is no button, no phone script, and no form that regenerates the exact document you lost.
What you request instead is Letter 147C, titled EIN Previously Assigned. The IRS issues the 147C specifically for EIN verification, and both it and the CP 575 are official IRS confirmation of the same EIN. Whether a particular bank or platform accepts one in place of the other is still that institution's own policy, which the banking section below covers. The practical difference is that the CP 575 comes once and the 147C can be requested again whenever you need fresh proof.
How to request a 147C as an international applicant
The 147C request runs through the IRS by phone, and the shape of the process is the same wherever you call from.
Lost your CP 575? The three steps to a Letter 147C.
The IRS instructs taxpayers to call the Business and Specialty Tax Line at 800-829-4933, open Monday to Friday, 7 a.m. to 7 p.m. local time. That number is US toll-free, which matters if you are dialing from abroad. The IRS also runs an international EIN application line at 267-941-1099, which is not toll-free. The primary IRS pages cite 800-829-4933 for the 147C request rather than the international line, so confirm the exact routing for your situation on the live IRS page before you call.
When you get through, the process detail is consistent. You confirm your identity as the person authorized to receive the EIN. Once the agent verifies you, the IRS sends Letter 147C to the business on record. Our detailed 147C guide walks through the request in more depth, including how to prepare before you call. Delivery is usually by mail, and a fax is possible in some cases after identity verification. We present the fax route and the exact international 147C phone terms as confirm-with-the-IRS, because the primary IRS pages do not spell them out.
CP 575 vs 147C: how they differ, why both prove your EIN
The two documents look different but carry the same weight. Here is the plain comparison:
CP 575 | Letter 147C |
|---|---|
One-time confirmation issued when your EIN is first assigned. | Verification letter you can request again later. |
The IRS does not duplicate or reissue the original. | Re-requestable by phone whenever you need proof. |
Accepted IRS proof of your EIN. | Accepted IRS proof of the same EIN. |
There is also a digital CP 575. The IRS makes it available through the Business Tax Account, and it can serve as a substitute for the original CP575A-J series and for Letter 147C. That sounds like the easy fix, but there is a catch for this audience.
Using your CP 575 or 147C to open a non-resident business bank account
For most of our readers, this is the whole reason the letter matters. A US bank or an EMI reviewing a non-resident LLC often asks for EIN proof, and either the CP 575 or a 147C can serve that role.
Be careful how you frame the guarantee, though. The IRS confirms the notice is used when EIN verification is requested for business purposes. The IRS does not say any bank must accept it. Whether a specific bank or EMI takes the CP 575, the 147C, or wants extra documents is that institution's policy, and it varies. This preparation does not guarantee approval, and no honest service can promise total anonymity or a sure account.
The practical move is to ask your chosen bank exactly which EIN document it accepts before you apply, then have that version ready. Some institutions want the original CP 575 specifically. Others accept a recent 147C, and a few also ask for formation documents alongside the EIN proof. CORPBOLT can prepare the paperwork, but the account decision belongs to the bank.
Keep the original safe, since you only get one
Because the notice gets pulled out whenever someone needs to verify your EIN, the IRS advises keeping the CP 575 in your permanent records and making several copies. Treat it as a document you protect rather than one you can casually replace.
Frequently asked questions
Can I get a replacement CP 575 online?
No. The IRS does not reissue or recreate the original CP 575. A digital CP 575 exists only inside the IRS Business Tax Account, which needs US-style identity verification. If you cannot use that account, you request Letter 147C by phone, and it proves the same EIN.
I lost the CP 575 and I do not know my EIN. How do I find it?
Start with your own records. The IRS lists a few legitimate ways to recover a lost EIN: find the computer-generated notice it issued when you applied, which is your CP 575; check a previously filed tax return, which shows the number; or contact a bank or licensing agency where you already used the EIN. If none of those turn it up, the authorized person can ask the IRS to look it up by calling the Business and Specialty Tax Line at 800-829-4933, 7 a.m. to 7 p.m. local time, and request Letter 147C. There is no public IRS database that returns a private company's EIN by name, so a paid "EIN lookup" site is not a substitute for IRS verification.
Is an EIN the same as a Tax ID or FEIN?
Yes. For a US LLC, the EIN doubles as your federal tax ID, and FEIN simply spells out the "federal" in front of it. All three terms point to the one number the IRS assigned your business.
Is the CP 575 the same as a CP 75 notice?
No. CP 75 is an unrelated IRS notice about an Earned Income Tax Credit examination, not an EIN confirmation. Do not confuse the two documents.
Is CP 575 a form I fill out?
No. CP 575 is a notice the IRS sends you, not a form you complete. The form you file to request the EIN is Form SS-4. Once the IRS assigns the number, it issues the CP 575 as confirmation, so there is no "CP 575 form" to download and submit.
How long does it take to get the CP 575 or a 147C?
Timing varies and we do not promise a date. The IRS publishes its own figures, such as EIN turnaround by fax versus mail. Check the current timeframe on the live IRS page for your situation.
Will my bank accept a 147C instead of the original CP 575?
Often, but that is bank policy, not IRS law. Both the CP 575 and the 147C are accepted IRS proof of your EIN. Each bank or EMI still decides which documents it requires, so confirm with yours before you apply.
