What Is a CP 575 EIN Letter? A Guide for Non-US Founders

A lot of non-US founders assume the CP 575 is some kind of certificate they have to chase down, renew, or pay a service to obtain. It is not. The CP 575 is simply the confirmation letter the IRS mails when it assigns your Employer Identification Number, and you only receive it once. If you have heard that you need a "fresh" CP 575 to open a bank account or that the letter expires, that is a myth worth clearing up before it costs you time.

What is a CP 575 EIN letter?

A CP 575 is the official notice the IRS sends to confirm that it has issued an Employer Identification Number to your business. The letter states your legal entity name, your EIN, the type of tax filings the IRS expects from you, and the date the number was assigned. It is the first and only document the IRS generates automatically when your EIN is created, which is why banks, payment processors, and accountants treat it as the primary proof that your EIN is real and tied to your specific entity.

For a non-resident founder, the CP 575 matters because you usually cannot walk into an IRS office or call from abroad to "look up" your number later. The letter is your record. Keep a clean digital copy and a printed copy somewhere safe, because reissuing it is not as simple as downloading a new one.

It also helps to understand what the CP 575 is not. It is not a license to operate, it is not a state registration, and it does not prove your LLC is in good standing with the Wyoming Secretary of State. Those are separate documents. The CP 575 speaks only to your federal tax identity, confirming that the IRS recognizes your entity by a specific name and number. Mixing these up leads founders to send the wrong document when a bank actually asked for something else.

Why do non-US founders need the CP 575 at all?

Non-US founders need the CP 575 because it is the document third parties ask for when they want to verify both your EIN and the exact legal name attached to it. When you apply to open a US business bank account from overseas, or set up a payment processor like Stripe or PayPal, the reviewer often wants to see an IRS-issued document that matches the name on your formation paperwork. The CP 575 is the cleanest match, because the IRS prints the name exactly as it appears in its own records.

Here is where it gets practical. Consider a founder in Guadalajara, Mexico who forms a Wyoming LLC to sell software subscriptions to US customers. When her payment processor asks for proof of her EIN, she does not have an SSN and cannot use a personal tax document. The CP 575 is the one piece of paper that proves the LLC, not a person, holds the EIN. Without it, she would be stuck explaining her structure in support tickets instead of getting paid.

Common situations where the CP 575 is requested include the following.

• Opening or applying for a US business bank account.
• Verifying your business with a payment processor.
• Onboarding with a US-based marketplace or supplier that needs tax details.
• Confirming your entity name and EIN with an accountant before filing.
• Providing documentation for certain US tax forms or W-9 requests from clients.

How do you get a CP 575 without an SSN?

You get a CP 575 without a Social Security Number by applying for the EIN itself with Form SS-4 and listing a responsible party who has no SSN or ITIN. The IRS allows a foreign responsible party to leave the SSN/ITIN field for the responsible party as "Foreign," and once the EIN is granted, the CP 575 follows automatically. There is no separate application for the letter. The number and the letter are issued together.

The catch for non-residents is the method. The IRS online EIN tool requires the responsible party to have an SSN or ITIN, so most non-US founders cannot use it. Instead, you submit Form SS-4 to the IRS by fax or mail. By fax, getting the EIN back typically takes a few weeks, and the IRS controls that timeline. No provider, including CORPBOLT, can promise you a specific date, because the speed depends entirely on the IRS workload.

This is the part many founders find frustrating, so it is worth being blunt. The EIN is free from the IRS. You never pay the IRS for the number itself, and you never pay anyone for the CP 575 as a standalone document. What you can pay for is the work of preparing and filing the SS-4 correctly, which is where a formation service earns its fee.

Getting your EIN without an SSN through CORPBOLT

CORPBOLT is a U.S. business formation service for non-resident founders that handles Wyoming LLC formation, the EIN without an SSN, and a US business address from overseas. Plans start from $349/year, with the EIN included from $599. (corpbolt.com)

In plain terms, CORPBOLT prepares and files the SS-4 so the IRS can issue your EIN, and the CP 575 arrives as part of that process. You are paying for the filing work and the supporting setup, never for the number, which the IRS always provides for free.

What is the difference between a CP 575 and a 147C letter?

The difference is that a CP 575 is issued once when your EIN is first assigned, while a 147C letter is a replacement confirmation you request later if you lose the original. The IRS does not reprint or re-send the CP 575. If your only copy is gone, you ask the IRS for a 147C, which is an EIN Verification Letter that states the same name and number for verification purposes.

For most non-US founders, the practical takeaway is simple. Treat your CP 575 as a one-time document and protect it. If you ever need proof again and cannot find it, the 147C is the official substitute, and banks generally accept either one. Knowing both exist saves you from panic if the original goes missing.

1. The CP 575 is the original, automatically mailed when the EIN is assigned.
2. The 147C is requested on demand, usually by phone or fax, as a replacement.
3. Both show the same EIN and legal entity name, so both serve as verification.
4. The IRS issues the CP 575 only once, so do not wait for a second copy.

How long does it take to receive the CP 575?

The CP 575 arrives once the IRS finishes processing your EIN application, which for non-residents filing by fax typically takes a few weeks. The IRS sets that pace, and it can shift depending on the season and the agency's backlog. There is no expedited paid lane for a foreign-owned LLC filing by fax, so be cautious of any claim that promises an exact turnaround.

One detail trips up new founders. Because the IRS mails the CP 575 to the address on your SS-4, the physical letter goes to your US business or mailing address. If you are filing from overseas without a reliable US address, the letter can be delayed or lost in forwarding. Having a US business address set up before you file, which is one of the things CORPBOLT provides, keeps the letter from disappearing into an international mail chain.

What should you do with the CP 575 once you have it?

Once you have the CP 575, save it, back it up, and use a copy for verification rather than the original. The letter is plain paper with no security features, so its value is the information on it, not the physical sheet. The moment it arrives, scan it to a secure location and store the paper copy somewhere you will not lose it.

A short checklist helps non-resident founders avoid common mistakes.

• Confirm the legal name on the letter matches your formation documents exactly, character for character.
• Verify the EIN digits against your SS-4 to catch any transcription error early.
• Store a digital copy in at least two places, such as cloud storage and an offline backup.
• Send copies, not the original, when a bank or processor requests proof.
• If you spot a name error, contact the IRS to correct it before the name spreads into bank records.

Returning to the founder in Guadalajara, the difference between a smooth verification and a stalled one often comes down to this discipline. She kept a clean scan of her CP 575 the day it arrived, so when a second processor asked for proof months later, she sent it in minutes instead of requesting a 147C and waiting again.

How does CORPBOLT fit into getting a CP 575?

CORPBOLT fits in by preparing and filing the paperwork that causes the IRS to issue your EIN, after which the CP 575 follows on its own. CORPBOLT does not issue the CP 575 and cannot speed up the IRS, because the IRS alone assigns the number and mails the letter. What CORPBOLT does is handle the steps a non-resident founder cannot easily do alone from abroad.

Specifically, CORPBOLT covers Wyoming LLC formation, the EIN without an SSN, a registered agent, and a US business and mailing address, and it helps you get bank-ready so you are prepared to approach a bank or processor. It does not open accounts or introduce you to a bank. The bank or platform always decides on its own. The honest framing is that CORPBOLT gets your entity, your EIN, and your address in order so the CP 575 lands where it should and your verification documents line up.

Frequently asked questions about the CP 575

Does the CP 575 expire?

No, the CP 575 does not expire, and your EIN does not expire either. The letter is a one-time confirmation, so a years-old CP 575 is still valid proof of your EIN as long as your legal entity name has not changed.

Can I get a duplicate CP 575 if I lose it?

No, the IRS will not reissue the CP 575 itself. If you lose it, you request a 147C letter instead, which is the IRS replacement that confirms the same EIN and entity name for verification.

Do I pay the IRS for the CP 575?

No, you never pay the IRS for the CP 575 or for the EIN. The number and the letter are free. You may pay a formation service to prepare and file Form SS-4 correctly, but that fee is for the work, not for the document.

Will a bank accept a CP 575 from a non-resident-owned LLC?

Many banks and payment processors accept the CP 575 as proof of an EIN for a US LLC, including one owned by a non-resident. The bank or platform still makes its own decision, so the CP 575 supports your application rather than guaranteeing approval.

Is the CP 575 the same as my EIN?

No, they are different things. The EIN is the nine-digit number the IRS assigns to your business, and the CP 575 is the letter that confirms and documents that number. You use the letter to prove the number belongs to your entity.
