Mercury Requirements for Non-Resident LLCs

Mercury is the go-to US business bank account for founders outside the US, but approval hinges on a few specific details. Here is exactly what Mercury requires, which countries it currently serves, and how to avoid the mistakes that get non-resident applications flagged.

What Mercury Actually Is

Mercury is a fintech, not a bank itself. Deposits sit with partner banks such as Choice Financial Group or Column Bank, while Mercury builds the software layer that founders actually use to move money, issue cards, and manage a US LLC's finances. This matters because Mercury's underwriting is a mix of its own risk rules and its banking partners' compliance requirements, which is why non-resident applications sometimes get extra scrutiny even when everything looks correct.

What Mercury Requires From Non-Resident Founders

You do not need to be a US citizen, US resident, or even hold a US visa to open a Mercury account. What you do need is a properly formed US company and a clean, verifiable application. At minimum, Mercury asks for:

• A US-registered LLC or C-corp, already formed with the state
• An EIN (Employer Identification Number) for that entity, or an EIN application already filed with the IRS
• A US business address, which can be your registered agent's address in most cases
• Government-issued photo ID for each beneficial owner, usually a passport
• Basic business details: what the company does, your website if you have one, and how you plan to use the account

Mercury does not require an SSN or ITIN to open the account. An ITIN becomes useful later for personal tax filings or certain card products, but it is not a gate to getting the business account itself.

Eligible Countries

Mercury supports founders from most countries, including the large majority of Europe, but it maintains a list of countries it will not onboard due to sanctions or heightened compliance risk. This list changes periodically, so always check Mercury's current published list before applying, but historically it has excluded countries such as Cuba, Iran, North Korea, Syria, Russia, Belarus, and a handful of others flagged for sanctions reasons. If your citizenship or country of residence sits in a genuinely high-risk category, Mercury may decline outright regardless of how strong the rest of your application is, and it is worth checking this before you spend time on formation and EIN paperwork.

Documents to Have Ready Before You Apply

• Certificate of formation or articles of organization for your LLC
• EIN confirmation letter (IRS Form CP 575) or proof the SS-4 has been filed
• Passport for every owner with 25% or more equity
• Proof of your personal residential address, such as a utility bill or bank statement, less than three months old
• A short, honest description of your business model and where your customers are based

Consistency matters more than people expect. The business name, address, and owner names on your LLC filing, your EIN paperwork, and your Mercury application should all match exactly. Small mismatches, like a missing suite number or a nickname instead of a legal name, are a common reason non-resident applications get pulled into manual review.

How To Improve Your Approval Odds

• Get your EIN before applying if possible, since an approved EIN speeds up verification significantly
• Use a real, functioning website or at least a simple landing page describing what you sell
• Avoid vague descriptions like 'consulting' or 'e-commerce' with no further detail, and be specific about your product, service, and target market
• Answer Mercury's follow-up questions quickly and directly if compliance reaches out, delays are the most common reason strong applications stall
• Steer clear of industries Mercury and its partner banks treat as high risk, including crypto, adult content, gambling, and certain money services businesses
• Keep your registered agent address consistent across every document, from formation to EIN to the Mercury application itself

Getting the LLC, EIN, and bank application sequenced correctly is where most non-resident founders lose time, which is exactly the gap Founders Credit is built to close. We handle the formation, EIN, and Mercury application as one coordinated process, so nothing arrives mismatched or out of order at the point Mercury reviews it.

What Happens After Approval

Once your account is live, Mercury gives you US routing and account numbers, virtual and physical debit cards, and access to Mercury's own credit card product once you build enough account history and revenue. Remember that owning a US LLC, even with zero revenue, typically triggers annual filing obligations, most notably Form 5472 alongside a pro-forma Form 1120, with a $25,000 penalty for missing the deadline. A bank account being open does not remove that filing requirement.

Quick Glossary

EIN: Employer Identification Number, the tax ID the IRS issues to your LLC, obtained via Form SS-4 and available to non-residents without an SSN. ITIN: Individual Taxpayer Identification Number, issued to people who need a US tax ID but are not eligible for a Social Security Number, no visa required. Registered agent: a person or company with a physical address in your LLC's home state, required by law to receive official mail and legal notices. Beneficial owner: anyone owning 25% or more of the LLC, whose identity must be disclosed during banking and, separately, under FinCEN's beneficial ownership reporting rules. Form 5472: an annual information return foreign-owned single-member LLCs must file alongside a pro-forma 1120, even with no income, that reports transactions between the LLC and its foreign owner.
