CP 575 Explained: The EIN Letter for Foreign-Owned LLCs

The CP 575 is a one-page IRS notice, and across foreign-owned LLCs it is among the most common documents to stall a bank or payment-processor onboarding. The pattern is consistent: the entity exists, the EIN is issued, and then the founder cannot produce the actual IRS letter proving the two belong together. The frustrating part is that most CP 575 problems are avoidable, and a few of them quietly cost founders weeks. This is an advisor-style walkthrough of what the document is, where it goes wrong, and how a non-resident owner keeps it from becoming a bottleneck.

What exactly is a CP 575 letter?

A CP 575 is the official IRS confirmation notice that assigns your business its EIN. Many founders search for the cp575 letter after a bank requests it, only to learn the term simply means this notice. The IRS generates it automatically once your EIN application is approved, then mails it to the address on the application. For a foreign-owned LLC, the CP 575 is usually the first and most authoritative proof that your entity has a US federal tax ID, which is why so many institutions treat it as the document of record.

The CP 575 letter shows your legal entity name exactly as the IRS recorded it, the nine-digit EIN, the tax form the IRS expects you to file, and the date the number was assigned. It is not an approval of your business, a license, or a tax return. It is simply the IRS saying: this entity exists in our system under this number. Treat it as a foundational record, not a one-time receipt you can lose track of.

Why do banks and processors keep asking foreign owners for it?

Banks and payment processors ask non-resident founders for the CP 575 because it independently links your LLC name to your EIN, which their compliance teams need before they open or activate an account. A non-resident applicant cannot walk into a branch with a passport and a utility bill the way a domestic owner might, so the paper trail does more of the work. The CP 575 is the cleanest way to show that the business and the tax number genuinely belong together.

Here is where I watch founders lose time. A processor will request EIN confirmation, the founder sends a screenshot of an email or a self-typed document, and the reviewer rejects it because it is not the actual IRS notice. The institution is not being difficult. It is matching a name against a number, and only an IRS-issued letter does that with authority. Sending the right document the first time is the single biggest time-saver in the whole onboarding process.

What is the most common CP 575 mistake non-residents make?

The most common CP 575 mistake is assuming you can request a replacement after you lose the original, which you cannot. The IRS issues the CP 575 only once, at the moment your EIN is assigned. There is no reprint, no duplicate, and no portal where you download another copy. Founders who treat the letter as something they can always re-pull later are setting up a problem for the day a bank finally asks for it.

The common mistakes cluster into a short, predictable list:

Discarding or never saving the original. The physical letter arrives once, often to a US mailing address the founder rarely checks, and gets thrown out or buried.
Expecting a re-issue. Founders assume the IRS will simply send another CP 575. It will not. The fallback is a different document entirely, the 147C verification letter.
Submitting a fabricated or edited copy. Retyping the details into a clean template feels harmless and is a serious error. Compliance teams can tell, and it can sink an application.
Putting the wrong name on the EIN application. If the entity name on the CP 575 does not match the name on your formation documents, every downstream institution will flag the mismatch.
Using a stale address. The CP 575 goes to the address on the application, so an outdated one means the letter lands somewhere you cannot reach.

I worked through this with a founder in Singapore who had formed his LLC, gotten the EIN, and then deleted the email scan during a phone cleanup six months later. When his US bank asked for the CP 575, there was nothing to send. He had not done anything reckless, he simply had not realized the document was irreplaceable. We routed him to the verification-letter path instead, and a five-minute habit of saving the original would have spared him the detour.

What happens if you lost the original CP 575?

If you lost the original CP 575, you request a 147C letter instead, which is the IRS verification letter that confirms the same EIN-to-entity match. The 147C is not a copy of the CP 575, but functionally it serves the same purpose for banks and processors: it ties your legal name to your number on IRS letterhead. Most institutions accept either document, so losing the CP 575 is recoverable, just slower and more manual.

Requesting a 147C as a non-resident usually means calling the IRS Business and Specialty line, confirming you are authorized to act for the entity, and asking the agent to send the letter. The IRS can fax it or mail it. Because mail to addresses outside the US is slow, many founders ask for the fax route and use an online fax service or their registered agent to receive it. The IRS controls the timing here, and no provider can promise a specific date.

How do you avoid CP 575 problems from the start?

You avoid CP 575 problems by saving the document the instant it exists and by making sure the EIN application carries the correct name and a reachable address. Almost everything that goes wrong later traces back to one of those two points. If you get them right at the application stage, the CP 575 quietly does its job and you rarely think about it again.

A practical sequence I give founders:

Confirm the exact legal entity name before you apply, matching it letter-for-letter to your Articles of Organization filed with your state.
Use a US address you actually control or monitor on the EIN application, so the CP 575 reaches you.
The moment the EIN is issued, scan or photograph the CP 575 at full resolution and store it in at least two places.
Keep the original paper letter too. Some institutions still prefer the physical notice or a clean color scan of it.
When a bank asks, send the unaltered document. Never retype or recreate it.

Notice that none of this requires an SSN. A non-resident founder with no US Social Security Number can still obtain an EIN by filing Form SS-4 with the IRS, typically by fax, after which the CP 575 follows. The no-SSN route is well established, and the CP 575 you receive is identical in authority to one issued to a domestic owner.

How do you get your EIN and CP 575 without an SSN?

You get an EIN and its CP 575 without an SSN by filing a paper Form SS-4 with the IRS rather than using the online tool, which is the part that trips up most foreign founders. The IRS online application is built for applicants who already hold an SSN or ITIN, so without one you cannot use the instant route. Instead you complete Form SS-4, list the responsible party, and submit it to the IRS by fax or mail. The EIN is free from the IRS; you only ever pay to prepare and file the application, never for the number itself. Once approved, the IRS issues the CP 575 to the address on that form. By fax, the process typically takes a few weeks, and the IRS, not any service, controls how long it actually runs.

This is the stage where founders often want a hand, because one wrong line on the SS-4 can cause a rejection or a name mismatch that haunts the CP 575 later. CORPBOLT is a U.S. business formation service for non-resident founders that sets up a US (Wyoming) LLC entirely remotely, with no SSN required. Plans start from $349/year, with the EIN included from $599. (corpbolt.com)

What that combination gives a non-resident, in practice, is the full starting stack in one place: a Wyoming LLC, the EIN obtained without an SSN, a registered agent, and a US business and mailing address. CORPBOLT also helps you get bank-ready, meaning it prepares the documentation, including your CP 575, so you walk into the application organized. It does not open or introduce accounts; the bank or platform always makes that decision. Keeping that line clear matters, because the CP 575 is a tool for the conversation, not a guarantee of the outcome.

How long should you keep the CP 575?

You should keep the CP 575 permanently, for the entire life of the LLC and ideally beyond it. The EIN never expires and never changes, so the document that proves it stays relevant every time you open a new account, switch processors, file taxes, or bring on a new accountant. Treat it the way you would treat your formation certificate: a permanent record, not a disposable one.

A small discipline pays off here. Store the CP 575 alongside your Articles of Organization, your operating agreement, and your SS-4 confirmation in a single, backed-up folder. When an institution asks for proof of your EIN three years from now, you want to find it in seconds, not reconstruct your way through the 147C process again.

Is a CP 575 the same as an EIN?

No. The EIN is the nine-digit number itself, and the CP 575 is the IRS letter that announces and confirms that number. You can have an EIN without holding the CP 575 in hand, but you will often need the letter to prove the EIN to a third party.

Can I get a CP 575 reissued by the IRS?

No, the IRS issues the CP 575 only once and does not send duplicates. If you no longer have it, you request a 147C verification letter instead, which confirms the same EIN-to-entity match and is widely accepted in its place.

Will a bank accept a 147C letter instead of a CP 575?

In most cases, yes. Banks and payment processors generally accept the 147C letter as equivalent EIN proof, because it confirms the same name-and-number link on IRS letterhead. Confirm with your specific institution, since requirements vary.

Do I need an SSN to get a CP 575 for my LLC?

No. A non-resident without an SSN obtains an EIN by filing Form SS-4 with the IRS, usually by fax, and the CP 575 follows automatically. The letter you receive carries the same authority as one issued to a US-based owner.

How long does the CP 575 take to arrive from abroad?

The IRS controls the timing, and after a faxed SS-4 it typically takes a few weeks for the EIN to be assigned and the CP 575 to be mailed. International mail can add further delay, which is one reason founders keep a reachable US address on the application.
