The CP 575 is the original EIN confirmation letter the IRS issues when your EIN is first assigned. It lists your 9-digit EIN, your legal entity name, and your federal filing requirements. The IRS cannot reprint it. If you lose the CP 575, request Letter 147C by calling 800-829-4933. Banks, Stripe, and Amazon accept either document to verify your EIN. For non-residents, ein.so files Form SS-4 by fax and emails you the confirmation for $49.

The CP 575 is the most important piece of paper in your US business file. It is the IRS proof that your Employer Identification Number belongs to your specific legal entity. Every US bank asks for it before opening a business account. Stripe, PayPal, and Amazon request it during verification. Yet the IRS issues the CP 575 only once and never reprints it, which makes it both essential and fragile. This guide explains what the CP 575 contains, how Letter 147C replaces it, how banks use it, and how non-US residents obtain it without an SSN by filing Form SS-4 by fax.

CP 575

What Is the CP 575 Letter?

The CP 575 is the Notice of EIN Assignment, the one-time letter the IRS sends when it first approves your EIN. It confirms your 9-digit EIN, your legal entity name, your address on file, and your federal filing requirements. The IRS issues it only once and cannot reprint it.

The CP 575 acts as your business's birth certificate in the US tax system. It links a specific 9-digit number to your exact legal entity name. Banks and payment platforms cross-check the name and EIN on this document against your other formation paperwork. A mismatch between the CP 575 and your LLC Articles of Organization causes account-opening rejections.

CP 575 Field	What It Shows
EIN	Your 9-digit number (XX-XXXXXXX)
Legal name	Entity name exactly as IRS recorded it
Mailing address	The address you entered on Form SS-4
Date assigned	The day the IRS approved your EIN
Filing requirements	The federal returns your entity must file
Form to file	Such as Form 1120, 1065, or 941

The IRS mails the CP 575 to the address on Form SS-4. When ein.so files by fax, the IRS returns the EIN confirmation on the fax response within 4-7 business days, and we email it to you. This avoids international postal delays that cause many non-residents to never receive the paper letter.

147C

How Do You Get Letter 147C as a Replacement?

You get Letter 147C by calling the IRS Business and Specialty line at 800-829-4933 and requesting it as a verification document. The IRS reprints the 147C unlimited times, unlike the CP 575. Banks accept the 147C as full EIN proof.

Letter 147C exists for one reason: the IRS cannot reissue the CP 575. When you lose the original confirmation or never receive it by mail, the 147C is your official replacement. It confirms the same core facts: your EIN, your legal entity name, and your address on file.

Call the IRS Business Line

Dial 800-829-4933, open Monday to Friday, 7am to 7pm Eastern time. Non-residents calling from abroad use international rates and must reach the line during US business hours.

Verify Your Identity

Confirm you are the responsible party named on the EIN. The agent asks for your EIN, legal entity name, and the address on file to verify you.

Choose Fax or Mail Delivery

Request the 147C by fax for 24-48 hour delivery or by mail for 10 business days. Provide a fax number you can access to receive it fastest.

Save the 147C as Backup

Store the 147C digitally and physically. Use it the same way you would use the CP 575 for banks, Stripe, and platform verification.

See the full IRS Letter 147C guide and the lost EIN recovery process for the complete steps.

Banking

Why Do Banks Require the CP 575 or 147C?

Banks require the CP 575 or 147C because it is the IRS proof that connects your EIN to your exact legal entity name. US banks use it to satisfy Know Your Customer rules before opening a business account. They reject applications when the entity name on the letter does not match your formation documents.

Opening a US business bank account as a non-resident requires a stack of documents, and the EIN confirmation letter sits at the center. Mercury, Relay, Chase, and Bank of America all request it. The letter proves your EIN is real and assigned to your entity, not a number you typed in error.

EIN Confirmation Letter

The bank wants the CP 575 or Letter 147C to verify your EIN matches your legal entity name. This is the document most account rejections trace back to. See EIN for a bank account.

LLC Formation Documents

Banks request your Articles of Organization or Certificate of Formation from your state. The entity name must match the CP 575 exactly, character for character.

Operating Agreement

Most banks ask for your LLC Operating Agreement to confirm ownership and the responsible party. The responsible party should match Line 7a on your Form SS-4.

Valid Passport

Non-resident owners present the same passport whose number appears on Line 7b of the SS-4. This ties your identity to the EIN confirmation letter.

Mercury and Relay approve most non-resident LLC owners remotely within a few business days once the EIN confirmation is in hand. The letter is non-negotiable, which is why protecting your CP 575 matters as much as obtaining it.

Non-Residents

How Do Non-US Residents Get a CP 575 Without an SSN?

Non-US residents get a CP 575 by filing Form SS-4 by fax to 855-215-1627 and entering a passport number on Line 7b. No SSN or ITIN is required. The IRS online tool requires an SSN, so the fax method is the only path for non-residents. The IRS returns the CP 575 within 4-7 business days.

The IRS online EIN application is the fastest route for US persons, but it hard-blocks anyone without a Social Security Number. Non-residents cannot use it. The fax method removes the SSN requirement entirely by accepting a foreign passport number as identification.

Form Your US LLC

Register an LLC in a state like Wyoming, Delaware, or New Mexico through a registered agent. This gives you a legal entity to attach the EIN to. You complete this online from outside the US.

Complete Form SS-4

Enter your LLC name on Line 1, your foreign address on Line 4, your full name as responsible party on Line 7a, and your passport number on Line 7b. ein.so completes this to prevent rejections.

Fax the SS-4 to the IRS

Submit the SS-4 to the IRS fax line at 855-215-1627. The IRS processes a correctly filed form within 4-7 business days and returns the CP 575 confirmation.

Receive the EIN Confirmation by Email

ein.so receives the IRS fax response and emails your EIN and confirmation to you, bypassing slow international mail. Standard is $49; Express is $97.

SS-4 Fields for Non-Residents

SS-4 Field	Non-Resident Entry
Line 1 (Legal name)	Your US LLC name
Line 4 (Address)	Your foreign mailing address
Line 7a (Responsible party)	Your full name as on your passport
Line 7b (SSN/ITIN/EIN)	Your foreign passport number
Line 10 (Reason)	Started new business
Line 16 (Activity)	Such as software, e-commerce, consulting

Cost & Time

How Much Does the CP 575 Cost and How Long?

The CP 575 costs $0 from the IRS because the EIN itself is free. ein.so charges a service fee to prepare and fax your Form SS-4 and deliver the confirmation by email: $49 Standard (4-7 business days) or $97 Express (2-3 business days). The IRS never charges for an EIN.

The EIN and its confirmation letter are free from the IRS. What you pay for with a service is the preparation, fax filing, and email delivery that bypass the international mail and SSN barriers non-residents hit. The table compares the two paths.

Path	IRS Fee	Service Fee	Delivery Time	Confirmation
DIY fax to IRS	$0	$0	4-7 business days if error-free	CP 575 by mail (international delays)
ein.so Standard	$0	$49	4-7 business days	EIN confirmation by email
ein.so Express	$0	$97	2-3 business days	EIN confirmation by email

The DIY route looks cheaper but carries risk. A single SS-4 error, such as a malformed foreign address, causes a silent IRS rejection that adds weeks. The paper CP 575 then ships by international mail, which many non-residents never receive. See EIN cost and EIN processing time for the full breakdown.

After the EIN

What Tax Filings Follow the CP 575?

A foreign-owned single-member US LLC must file Form 5472 with a pro-forma Form 1120 each year after receiving its EIN. The penalty for not filing is $25,000. The CP 575 confirms the EIN that these annual filings reference. ein.so handles the EIN and does not give tax advice.

Your CP 575 confirms the start of your US tax obligations, not the end. The filing requirements listed on the letter tell you which federal returns your entity owes. For most non-resident-owned LLCs, the key filing is Form 5472.

Form 5472 + Pro-Forma 1120

A foreign-owned single-member US LLC files Form 5472 with a pro-forma Form 1120 annually. The penalty for missing it is $25,000. This is an information return, not always a tax bill.

BOI Report to FinCEN

Most US LLCs report beneficial ownership to FinCEN. Review the BOI filing rules to confirm your deadline and avoid penalties.

State Annual Report

Your formation state may require an annual report and fee to keep the LLC in good standing. Confirm the exact amount and date with your registered agent.

Confirm With a CPA

Tax specifics depend on your country, treaty status, and income type. Work with a US CPA familiar with non-resident matters. ein.so files the EIN and does not provide tax advice.
