EIN for a non-resident LLC: getting an EIN without an SSN
An EIN for a non-resident LLC is obtained by filing Form SS-4 with the IRS, and you do not need a Social Security Number to get one. This is the single point that confuses most founders outside the US: the IRS online EIN assistant requires an SSN or ITIN, but that tool is only one of several routes. Applicants without a US tax identification number apply by fax or mail, and in defined circumstances through the IRS international applicant telephone line.
This guide explains what an EIN is, why your LLC needs one, how each application method works, what a correctly completed SS-4 looks like for a foreign owner, how long to expect to wait, why applications get rejected, and how to recover the number if you lose it.
What an EIN actually is
The Employer Identification Number is a nine-digit federal tax identification number issued by the IRS to business entities, formatted as XX-XXXXXXX. It identifies your company to the federal government in the same way an SSN identifies an individual. Despite the name, you do not need employees to have one, and having one does not imply you owe US tax.
- It is issued once and stays with the entity for its lifetime.
- It is not a licence, a tax status, or proof of anything beyond entity registration with the IRS.
- It is free to obtain directly from the IRS; third parties charge for handling, not for the number itself.
- It is distinct from an ITIN, which is a personal taxpayer number for individuals who cannot get an SSN.
Why non-resident LLC owners need one
- Opening a US business bank account — no serious bank or fintech will onboard an entity without one.
- Applying to payment processors and marketplaces that require a US tax ID for the account holder.
- Filing federal returns, including the information return and Form 5472 that most foreign-owned single-member LLCs must file.
- Issuing and receiving US tax forms such as 1099s when you work with US contractors.
- Completing W-8 or W-9 style documentation requested by US clients.
- Registering for state-level accounts such as sales tax, where applicable.
Apply only after the state has approved your formation filing. An EIN issued against a name or formation date that does not match the state record creates mismatches that surface later during bank onboarding.
The three application methods
| Method | Who it suits | Practical notes |
|---|---|---|
| Fax | Most non-resident founders | Generally the fastest route without an SSN; include a return fax number |
| Founders with no fax access | Slowest option; allow for international postal time in both directions | |
| International phone line | Applicants meeting IRS criteria for phone issuance | Requires being able to answer SS-4 questions live; the authorised person must be on the call |
| Online assistant | Applicants who already hold an SSN or ITIN | Not available to applicants without a US tax ID |
IRS fax numbers, mailing addresses, and phone hours for international applicants are published on the IRS website and are updated periodically. Always confirm the current contact details on irs.gov immediately before submitting rather than relying on a number copied from an older article.
Completing Form SS-4 as a foreign owner
Form SS-4 is a single page, but for foreign applicants a handful of lines cause almost all of the problems. The guiding principle is consistency: every name, address, and date on the SS-4 should match the approved state filing exactly.
- Legal name of entity: type it exactly as approved by the state, including the LLC designator and any punctuation.
- Mailing address: an address where the IRS can reach the company; a foreign address is acceptable.
- Responsible party: the individual who ultimately controls the entity — a real person, not the company itself and not a service provider.
- Responsible party's identifying number: write FOREIGN if the responsible party has no SSN or ITIN rather than leaving it blank.
- Type of entity: select the correct classification for a limited liability company and state the number of members.
- Reason for applying: usually started a new business, or banking purposes.
- Date business started: match the formation date on the state filing.
- Third party designee: complete only if you want someone else authorised to receive the EIN on your behalf.
An unsigned SS-4 is one of the most frequent reasons a fax submission produces no response. The responsible party or a validly authorised designee must sign and date it before you send it.
Realistic timelines
The IRS does not guarantee turnaround times, and processing speed varies with season and workload. Fax submissions are generally the quickest option for applicants without an SSN, often measured in weeks rather than days. Mailed applications take substantially longer once international postal time is added at both ends. Applications filed near peak US filing season tend to sit longer.
- Do not resubmit the same application repeatedly — duplicate submissions can create duplicate records and further delay.
- Keep the fax transmission confirmation; it is your evidence of the submission date.
- Plan your banking and processor applications around the EIN, not the other way around.
Common rejection and delay reasons
| Issue | Why it happens | Prevention |
|---|---|---|
| Entity name mismatch | SS-4 name differs from state record | Copy the name character-for-character from the approved filing |
| Blank responsible party ID | Applicant has no SSN and leaves the field empty | Enter FOREIGN in that field |
| Company listed as responsible party | Founder names the LLC instead of a person | Name the individual with ultimate control |
| Unsigned form | Signature block skipped | Sign and date before sending |
| Wrong entity classification | Boxes ticked inconsistently | Match the classification to how the LLC is actually owned |
| Duplicate applications | Founder refiles while the first is pending | Wait, then follow up rather than refiling |
| Unreachable return contact | No return fax or wrong address | Provide a reliable return fax number and address |
If you lose your EIN: Form 147C
If the original CP 575 confirmation letter is lost, the IRS will not issue a duplicate of that letter. Instead you request an EIN verification letter, known as a 147C. It is requested from the IRS business line by the responsible party or an authorised representative, and it is accepted by banks and processors as proof of the EIN.
- Have the legal entity name and formation state ready
- Know the EIN if you have it recorded anywhere, such as an old bank form
- Be prepared to confirm the responsible party's details
- Have a fax number or mailing address ready to receive the letter
- Call during the published hours for international callers
Save a digital copy of the EIN confirmation letter in at least two places as soon as it arrives. Nearly every future application — banking, processors, tax filings — will ask for it.
What an EIN does not do
- It does not create US tax residency for you personally.
- It does not guarantee bank or payment processor approval.
- It does not replace an ITIN where a personal taxpayer number is required.
- It does not exempt you from state-level registrations or licences.
- It does not, by itself, determine whether US federal income tax is owed.

Frequently asked questions
Can I get an EIN without an SSN?
Yes. Applicants without a Social Security Number or ITIN cannot use the IRS online assistant, but they can apply by filing Form SS-4 by fax or mail, and in defined circumstances through the IRS international applicant telephone line. Enter FOREIGN in the responsible party identification field rather than leaving it blank.
How long does an EIN take for a non-resident LLC?
The IRS does not guarantee a turnaround time. Fax submissions are generally the faster route for applicants without an SSN and are usually measured in weeks, while mailed applications take considerably longer once international postal time is added at both ends.
Who should be listed as the responsible party on Form SS-4?
The responsible party must be an individual who ultimately controls the entity, not the LLC itself and not a service provider. The name should match the ownership shown in your formation documents and operating agreement.
What is Form 147C and when do I need it?
A 147C is an EIN verification letter issued by the IRS when the original CP 575 confirmation letter is lost. The IRS will not reissue the CP 575, so the 147C is the accepted substitute and is requested by phone by the responsible party or an authorised representative.
Why was my EIN application rejected or ignored?
The most common causes are an entity name that does not match the state filing exactly, a blank responsible party identification field, naming the company instead of a person as responsible party, an unsigned form, or duplicate submissions filed while the first was still pending.
