Lost EIN Confirmation Letter: CP 575, 147C and What Banks and Acquirers Accept

The IRS issues the CP 575 once, when it assigns the EIN, and never reissues it. A lost letter is replaced by a 147C verification letter, requested from the IRS by an authorized person and generally accepted by banks and acquirers as equal proof. The legal name on the letter must match the articles and the bank record; a real mismatch is corrected at the IRS before you apply. An IBOCore package ships with the EIN letter in the bundle.

The CP 575 is the notice the IRS issues once, when it assigns an EIN, and it is never reissued. If the letter is lost, the entity asks the IRS for a 147C EIN verification letter, which banks and acquirers generally accept as the same proof: an IRS document showing the legal name and the EIN together. An underwriter checks that the name on that document matches the articles and the bank record, allowing for the IRS's own formatting; when it does not, the IRS record is corrected first and a fresh 147C obtained afterwards. An IBOCore package skips the search: the EIN is issued before the package is listed, and the letter ships in the document bundle.

What the CP 575 notice is, and why the IRS does not reissue it

When the IRS assigns an Employer Identification Number to a new entity, it generates one confirmation notice, Notice CP 575. An online applicant receives it at the end of the session as a document to save; a fax or mail applicant receives it later, by fax or by post. The IRS does not print a second CP 575 later: the notice records the assignment on the day it happened, it is not a certificate the entity can renew. Instead, the IRS verifies the number on its current record with the 147C described below. The CP 575 shows four things an underwriter reads.

• The legal name of the entity, typically printed in capitals, without punctuation such as commas and periods.
• The EIN itself, nine digits in the format 12-3456789, next to the name.
• The mailing address given on the application, usually with the responsible party's name and a title abbreviation in the address block.
• The date of assignment and the returns the IRS expects, which show how the entity is classified for tax. What that classification should be is a question for a professional.

The 147C letter: the replacement banks and acquirers accept

Letter 147C is the IRS's EIN verification letter. It confirms that a given EIN belongs to a given legal name and shows the name and address the IRS holds at the moment of the request, so after a correction it is the document that proves the record was updated. Banks and acquirers generally treat the 147C and the CP 575 as equivalent: both are IRS-issued documents that pair the legal name with the number. Requesting one is a short procedure, in outline.

1. An authorized person calls the IRS business tax line. The IRS releases the letter only to the responsible party on the record, an officer or member, or a third party holding a written authorization on the IRS's own form; a formation service or an ISO cannot request it for you unless it holds that authorization.
2. The caller answers identity questions about the entity: legal name, the EIN if known, the address on record, the entity type and details about the responsible party.
3. The letter is sent by fax during the call or by mail to the address on record. The IRS sets the timing and does not send it by email.
4. Save the copy as delivered. Keep a clean scan next to the articles and the operating agreement; banks and acquirers the entity approaches will typically ask for it.

What banks and acquirers accept as proof of the EIN

A US bank collects and checks the entity's taxpayer identification number as part of its customer identification program; an acquirer checks it during KYB before it issues a MID. Both compare the document against the articles, the bank record and the application. The table shows what is typically accepted; policy varies by institution, so ask the bank or your ISO first.

The name is checked first because of the settlement account. Acquirers typically require the settlement account to be held in the entity's legal name, and the bank opened that account against the same EIN document. If the letter says one name and the articles another, the underwriter cannot tell which entity is applying, and the file stops.

When the letter does not match the articles: name and address mismatches

A mismatch between the EIN letter and the state filing usually starts on the EIN application, and it is how a lost-letter problem becomes an underwriting problem: the underwriter reads the discrepancy and asks what else in the file is wrong. Five cases recur.

• Spelling and abbreviation. Acme Holdings, L.L.C. on the articles and ACME HOLDINGS LLC on the letter is IRS formatting, not a different name. A missing word or a transposed letter is a real discrepancy.
• A trade name on the application. The EIN was requested under the DBA or a brand instead of the legal name, so the IRS record carries a name the state never registered.
• A name amended after formation. The entity changed its name with the state, but nobody told the IRS, so the letter still shows the old name.
• The formation service's address. The mailing address is the agent's suite or an accountant's office, not the principal office; the address mismatch guide covers where each address belongs.
• A responsible party who has left. The address block names a formation agent's employee or a former member, not the person who now signs for the entity.

The fix follows the rule for any document mismatch: correct the record at its source, never the document. A formatting difference needs no correction, only a one-line note to the ISO. A wrong or outdated legal name is reported to the IRS through its name-change procedure; which route applies depends on how the entity is classified for tax, and the professional who handles its returns decides. A wrong address or a departed responsible party is reported on the IRS change form for businesses (Form 8822-B); whether and when to file it is for the same professional. None of these corrections changes the EIN. Once the IRS has processed the change, an authorized person requests a 147C, which then replaces the old CP 575 in every application.

How to keep the EIN letter usable for underwriting

1. Scan the CP 575 the day it arrives, in one piece and unedited, and store it with the articles and the operating agreement; the scan is what gets sent.
2. Copy the legal name into every application exactly as the articles spell it, and attach the letter rather than typing the number.
3. Check the address block against the articles and the bank record before the first application, so you find a mismatch before the underwriter does.
4. Keep the responsible party current: the IRS releases the 147C only to a person it recognizes as authorized for the entity, and an outdated record makes that call harder.

The EIN letter inside an IBOCore package

An IBOCore package is a US LLC or C-Corp incorporated in the home state of its director, the Independent Business Operator (IBO), with the EIN already issued. The EIN letter is part of the document bundle, next to the articles, the operating agreement and the director's government ID and proof of address, so the entity name on the IRS record, on the state filing and on the business bank account opened at Bluebanc or Relay in the company's name is one and the same. The director is a real, KYC-verified US resident with zero criminal record and a credit score of 650 or more, exclusive to one merchant and never used before; that is the person on the state filing and on the EIN. Because the entity is formed where the director lives, the state filing and the EIN record point to a person who holds a driver's license and a utility bill in that state. If an acquirer later asks for a 147C, raise it in the private Telegram group with your account manager: the IRS releases it only to a person authorized for the entity, and that is the director's side of the collaboration. Nothing is asked of you personally, no KYC, no notary, no travel.

The package ships the same day the payment confirms, from inventory that is permanently in stock; acquirer onboarding then typically takes 3 to 10 business days, on the acquirer's own timeline. The IBO package costs $999 setup, then $2,999 per month from 30 days after delivery, whatever the vertical or the billing model. What the documents show is the director on the state filing and on the EIN record, nothing more. On beneficial ownership reporting, the status at the time of writing is that a US-formed LLC or corporation is a domestic reporting company and, under FinCEN's interim final rule of March 2025, domestic companies and US persons are exempt from BOI reporting, while companies formed under foreign law that register in a US state remain subject to it; verify current FinCEN guidance before relying on that. IBOCore gives no legal or tax advice; your own reporting and filing position is settled with a professional.

Questions merchants ask

Can I send a 147C instead of the CP 575 with a merchant application?

Yes. Banks and acquirers generally treat the two as equivalent proof, because both are IRS documents that pair the legal name with the EIN. The 147C has one advantage: it shows the record as the IRS holds it today, so after a name or address correction it is the better document. Send whichever you have, unedited.

The EIN letter in my bundle carries the director's name. Is that a problem for the acquirer?

No. The IRS address block names the responsible party, and in an IBOCore package that is the director, the same person on the articles, the operating agreement and the bank account. An underwriter typically expects the responsible party on the EIN record to be the person who signs the application and takes the verification call, so the letter confirms the file. What raises questions is a letter naming a formation agent nobody in the file has heard of.

Does the EIN letter expire, and should I request a new 147C every year?

No. An EIN is assigned once and stays with the entity; it is not renewed, and the letter has no validity period. A CP 575 from the year of formation is generally accepted years later, and so is an older 147C; an institution that wants a recent IRS document says so, and a fresh 147C answers that. Otherwise the only reason to request a new one is a change in the IRS record: the legal name, the address or the responsible party. Keep sending the scan you already have.

Formation is step one; processing is step two

A Wyoming LLC or Delaware INC gives you a legal shell. It does not give you a business bank account, EIN usable with processors, or a US signer for the guarantor line on the MID application. Formation agents sell the entity; IBOCore ships the operational package (signer, bank pack, processor-ready KYB folder) with instant delivery from inventory.

• Registered agent: statutory mail recipient; not a substitute for an IBO.
• Operating agreement: defines manager vs member; processors may request it.
• Articles of organization: proof of incorporation date and state.
• FinCEN BOI: names beneficial owners; penalties for false filings.

Formation-only packages that never reach processing

Stripe Atlas and DIY LLC shops stop at incorporation. Operators still need EIN, US bank, signer and processor pack. Buying formation twice because the first vendor could not board a nutra MID is common; start with an instant-delivery IBO inventory slot instead.

FAQ: quick answers

How fast can I get an IBO package on IBOCore?

Available inventory ships the same day after payment. You receive Articles, EIN letter, registered agent details, bank onboarding pack and signer contact through your merchant dashboard. Processor onboarding typically follows over the next one to two weeks.
