This service is built for these situations
You want to open a Mercury account
Mercury supports non-U.S.-resident founders with U.S. LLCs. The EIN is required.
Mercury rejected your previous application
Usually fixable — and often a name-matching issue, not a substantive one.
You have a foreign-owned LLC
Mercury's sweet spot. We work with this combination daily.
You need to fund Stripe, Wise, or Payoneer via Mercury
Mercury's ACH support makes it the hub bank for many international founders.
You're running an online business
SaaS, e-commerce, freelance services — Mercury is built for digital businesses.
You're moving from PayPal-only
Tired of PayPal fees? Mercury offers U.S. business accounts without monthly fees (check its current pricing).
Getting an EIN as a non-U.S. founder is full of small traps
The IRS process wasn't designed with international applicants in mind. Most rejections and multi-month delays come from a handful of avoidable mistakes.
Common pitfalls
What usually goes wrong when filing alone
- "Trade name" differs from legal name on Articles, then differs again on the EIN letter.
- EIN letter received but in a degraded scan format that Mercury's verification can't parse.
- Business activity description on SS-4 doesn't match what you tell Mercury.
- Mercury sends a verification email asking a question — and you don't know how to respond correctly.
Our approach
How we prevent each of those problems
- Every name (passport, Articles, SS-4, Mercury form) matches before submission.
- EIN letter delivered as a clean PDF, suitable for Mercury upload.
- Business description coordinated between SS-4 and your Mercury application.
- Mercury verification questions? Forward them to us — we'll draft your response.

Common questions from non-U.S. applicants
If your question isn't here, contact us — we'll answer honestly, even if the answer is 'this isn't a fit for our service.'
Does Mercury actually accept non-U.S. residents?
Yes. Mercury (a fintech, with accounts held at partner banks) is one of the few U.S. business-account providers that opens accounts for LLCs owned by non-U.S. residents, subject to its own eligibility checks. You'll need an EIN, formation documents, ID, and a clear answer to a few KYC questions.
How long after I get my EIN can I apply to Mercury?
Immediately. As soon as you have the EIN confirmation letter, you can complete the Mercury application. Many of our clients open their account within a week of receiving the EIN.
Will Mercury accept the EIN confirmation right from the IRS?
Yes — the IRS-issued EIN confirmation letter (CP 575) is the gold standard. If you've lost yours, you can request a 147C letter from the IRS, which Mercury also accepts. We can help with either.
Why do Mercury accounts get rejected after the EIN is issued?
Most rejections come down to: (1) name mismatch between formation docs and EIN, (2) industry restrictions on Mercury's side, (3) sanctioned-country residence, or (4) unclear business activity. We help prevent issue #1 and #4. The other two we'll flag during onboarding.
Can I open a Mercury account before forming my LLC?
No — Mercury requires a U.S.-formed entity (LLC or C-Corp). The order is: form the LLC → get the EIN → apply to Mercury.

The IRS determines its own processing times, which may vary depending on application volume. Faxed applications requiring a response by mail can take 1–3 months to process. We simplify the process by following up with the IRS on your behalf and keeping you informed of your application status. Once your EIN is assigned, we notify you promptly. While processing times cannot be guaranteed, we strive to make the experience as smooth and straightforward as possible. All prices are listed in USD with no hidden fees, and payments can be made securely through PayPal using supported international payment methods.
