Lost Your EIN? How Non-Residents Recover It

You finished your Wyoming LLC months ago, opened a few accounts, filed a form or two, and then a payment processor asks for your EIN and you realize you cannot find it anywhere. For a non-resident founder running everything by email and PDF, that confirmation letter often lives in an inbox you no longer check or a folder you cannot locate. A lost EIN number is not gone, it is just misfiled, and the IRS keeps a permanent record of every one it issues. Here is exactly how non-residents recover it without an SSN and without flying to the United States.

What does it actually mean to lose your EIN?

Losing your EIN means you have misplaced the document that shows the number, not that the number itself has expired or been cancelled. The IRS assigns an Employer Identification Number to your business permanently, so once your Wyoming LLC has one it stays attached to that entity for the life of the company. The recovery problem is almost always a documentation problem: the CP 575 confirmation letter, the email it came in, or the file you saved it to has been lost.

That distinction matters because it changes what you are looking for. You do not need to apply again or request a replacement number. You need to find the existing number on a record you already have, or get the IRS to read it back to you. A second application for the same entity can actually create a duplicate EIN, which causes filing problems later, so reapplying is the wrong move.

Where is your EIN most likely hiding?

Your EIN is most likely sitting on a document you already received, and checking those first is faster than contacting the IRS. Before you call anyone, work through the places the number gets recorded automatically when you form a company and operate it.

• The CP 575 letter. This is the official confirmation notice the IRS issues when your EIN is granted. Search your email for "CP 575", "EIN", or "Employer Identification Number" across every account you used during formation.
• Your SS-4 application copy. The Form SS-4 you or your agent submitted lists the entity details, and the granted number is often written on the returned copy or fax confirmation.
• Bank documents. If you completed account opening, the bank recorded the EIN on the application and account paperwork, so a statement header or onboarding email may show it.
• Past tax filings. Any return filed for the LLC, such as Form 5472 with a pro forma 1120, carries the EIN on the first page.
• Payment platform records. Processors like Stripe and PayPal store the tax ID you entered during verification, visible in your account settings.
• Your formation provider's records. Whoever filed the application usually keeps a copy of the confirmation.

Work down that list in order. Most founders find the number within the first two or three places without ever needing to phone the IRS.

How do non-residents recover a lost EIN from the IRS?

Non-residents recover a lost EIN by calling the IRS Business and Specialty Tax Line and asking an assistor to look it up after verifying that they are authorized to receive it. The IRS will not email or text the number for security reasons, so the phone is the official channel when your own documents come up empty. You do not need a Social Security Number to be verified; the agency identifies the entity and confirms you are an authorized person, such as a managing member of the LLC.

Be ready before you dial. Have the legal name of the LLC exactly as registered with the Wyoming Secretary of State, the business mailing address on file, the name of a responsible party, and any partial reference you have such as an old letter or the date the EIN was issued. The assistor uses these details to match your record. Once they confirm your authority, they read the EIN back to you over the call.

For founders outside the United States, the practical hurdle is the time zone and the international call, not the verification itself. The line operates during US business hours, so a founder in the UAE or Singapore should plan the call for late afternoon or evening local time. Keep your documents on screen so you can answer every identity question without hunting.

Can someone request the EIN on your behalf?

Yes, an authorized representative can request the EIN for you, but the IRS will only release it to a person it can confirm is connected to the entity. A managing member, officer, or someone holding a valid third party authorization can make the call and receive the number. A registered agent or formation provider who filed the original application can also often retrieve their copy of the confirmation without involving the IRS at all.

This is the point where a real human on your side matters. One founder in the UAE had formed a Wyoming LLC, lost the original confirmation in a deleted email account, and could not get through the US phone line during his working hours. Walking through which of his own records carried the number, and confirming the exact registered company name to use, turned a stalled week into a ten minute fix. He found the EIN on an old payment processor verification screen before the IRS call was even needed.

What if you never actually got your EIN in the first place?

If you have never successfully obtained the EIN, then recovery is not your problem, application is. Non-resident founders without a Social Security Number cannot use the IRS online EIN tool, which rejects applicants who lack an SSN or ITIN. Instead you file Form SS-4 by fax or mail, leaving the responsible party SSN field handled the way the IRS instructions allow for foreign applicants. The IRS controls the timing, and by fax it typically takes a few weeks; no provider can promise a specific date.

This is the gap CORPBOLT is built to close for founders who do not want to manage the SS-4 process alone.

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

To be clear about what that covers: CORPBOLT forms the Wyoming LLC, prepares and files the EIN application without requiring an SSN, provides a registered agent, and gives you a US business and mailing address where official notices can arrive. The EIN itself is always free from the IRS; you pay only to prepare and file the application correctly, never for the number. Because the formation provider keeps a copy of the confirmation, having filed through a fully remote service that retains your records also makes a future lost EIN number much easier to recover.

What documents prove your EIN once you have recovered it?

The strongest proof of your EIN is the CP 575 confirmation letter, and once you recover the number you should save a clean copy in more than one place. If the original CP 575 is permanently lost, the IRS can issue a Form 147C verification letter, which serves the same function for banks and platforms that ask you to confirm the number. You request the 147C on the same Business and Specialty Tax Line call.

Store whichever document you obtain somewhere durable. A few habits prevent a repeat scramble:

1. Save the confirmation letter as a PDF in cloud storage that is not tied to a single email login.
2. Record the EIN itself in a password manager or secure note, separate from the document.
3. Keep the registered company name and formation date alongside it, since those are what you will need to verify yourself later.
4. Share access with a co-founder or trusted contact so the number is not locked to one person's account.

A non-resident operating remotely loses documents to closed inboxes and forgotten folders more often than anyone admits. Two minutes of filing now is cheaper than an international phone call later.

How long does EIN recovery take for a non-resident?

EIN recovery is usually fast when the number already exists, because you are retrieving a record rather than applying. Finding it on your own documents takes minutes. The IRS phone lookup takes as long as the hold time plus a short identity check, and a 147C letter, once requested, is sent to your address on file. The slow part for non-residents is rarely the IRS itself; it is matching US business hours and having every verification detail ready before you call.

Contrast that with a fresh application, where the IRS controls the schedule and fax filing typically takes a few weeks. Recovery is the easier path, which is exactly why reapplying for a number you already hold is a mistake to avoid.

Does a lost EIN expire if I have not used it?

No. An EIN never expires once the IRS issues it, even if the business has not filed or transacted yet. The number stays permanently linked to your LLC, so a lost EIN is always recoverable rather than reissued.

Can I get my EIN by email from the IRS?

No. The IRS does not send EINs by email or text for security reasons. You recover it by phone through the Business and Specialty Tax Line, or you find it on documents you already hold such as the CP 575 letter or a prior filing.

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

The CP 575 is the original confirmation the IRS sends when your EIN is first granted, while the 147C is a verification letter you request later if the original is lost. Both display the same EIN and both are accepted by banks and platforms as proof.

Do I need an SSN to recover a lost EIN?

No. You do not need a Social Security Number to recover an EIN that already exists. The IRS verifies you as an authorized person tied to the entity, using the LLC's legal name, address, and responsible party details, which non-resident founders can provide.

Should I apply for a new EIN if I cannot find the old one?

No, you should recover the existing one. Applying again for the same Wyoming LLC can create a duplicate EIN, which causes filing and banking confusion. Call the IRS or check your own records to retrieve the number you already have.
