How to Open a Mercury Bank Account for a Non-US LLC — 2026 Complete Walkthrough

Why Mercury Is the Go-To Bank for Non-Resident LLC Owners

Before Mercury (founded 2019), non-resident US LLC owners had two options: a multi-week in-person banking process at a US bank (requiring a US trip and often failing anyway), or operating without a US bank account entirely. Mercury changed this with a fully online, document-based application process that genuinely works for non-residents.

• Key features that matter for non-residents:
• No minimum balance requirement (no monthly fees)
• No physical presence required — fully remote application
• ACH transfers: Send and receive USD within the US
• International wires: Send to 130+ countries in multiple currencies
• Stripe integration: Payouts from Stripe deposit directly to Mercury
• Debit card: Physical and virtual debit card issued
• API access: Full-featured API for fintech/developer founders

Mercury is not a traditional FDIC-member bank — it operates through partner banks (Evolve Bank & Trust, Choice Financial Group) and provides FDIC insurance up to $5M through a sweep network. It's FDIC-insured to the standard $250K limit and extended through the sweep program.

Step-by-Step: How to Open Your Mercury Account

Step 1: Prepare your documents before starting the application

• You will need:
• EIN Confirmation Letter (CP575): The physical letter from the IRS confirming your LLC's Employer Identification Number. Note: the CP575 is the original confirmation letter. If you've lost it, you can get an EIN Verification Letter (147C) by calling the IRS. Mercury accepts both.
• Articles of Organization: Your LLC's formation document from the state Secretary of State. For Wyoming LLCs: the Certificate of Organization. For Delaware LLCs: the Certificate of Formation.
• Operating Agreement: Not always required, but have it ready. If Mercury requests it, you need one.
• Passport: Your government-issued ID. Must be current and clear.
• Business description: Mercury will ask what your company does — prepare a 2–3 sentence clear description. "I provide software development services to international clients" is fine. "Consulting" with no further detail may trigger additional questions.

Step 2: Go to mercury.com and click "Apply"

• The application asks for:
• Business name, state of formation, EIN
• Your name, address (can be a non-US address — explicitly supported), date of birth
• What the business does, expected monthly transaction volume
• Whether you have any beneficial owners with 25%+ ownership (UBO certification — required under US Bank Secrecy Act)

Upload your EIN letter and formation documents when prompted.

Step 3: Wait for decision (1–5 business days)

Mercury performs KYC/AML checks. For straightforward applications (clean passport, real business description, clear EIN, formation docs in order), most decisions are made within 1–2 days.

• If Mercury requests additional information, they'll email you. Common additional requests:
• A website URL (even a basic landing page helps)
• Proof of address for the business owner
• Operating Agreement

Step 4: Account activated — set up your payments

• Once approved:
• Set up your Stripe account to pay out to Mercury (Add bank account → ACH routing number + account number from Mercury)
• Configure Stripe Atlas integration if you used Atlas for formation
• Order your physical debit card (ships to international addresses)

Why Mercury Rejections Happen (and How to Fix Them)

Mercury rejects approximately 5–15% of applications (estimated). Common reasons:

1. Vague business description "E-commerce" with no further detail, "general trading," or "consultant" with no specifics. Mercury's compliance team needs to understand what the business actually does and who it serves. Fix: Add specific detail. "I run a Shopify store selling handmade jewellery to US customers" is better than "e-commerce."

2. High-risk business category Crypto exchanges, cannabis, firearms, adult content, and gambling are prohibited. Adjacent businesses (crypto wallet software, CBD products) may trigger additional review. Fix: If you're in a borderline category, provide extensive documentation of your specific activities. Consider using a more specialist bank if you're in a genuinely high-risk category.

3. Sanctions or PEP concerns Applications from certain countries (Iran, North Korea, Cuba, Syria — under OFAC sanctions) will be declined. Applications from nationals of high-risk countries (certain African, Asian, and Middle Eastern countries per FATF guidance) may face additional scrutiny. Fix: Ensure your application is exceptionally clear, with a thorough business description and clear source of funds. If still rejected, try Relay Bank, Wise Business, or Airwallex as alternatives.

4. No EIN or incorrect EIN A common issue for recently formed LLCs. The EIN confirmation letter (CP575) takes 4–6 weeks by mail. Some applications are filed before the letter arrives. Fix: Wait for the CP575 before applying to Mercury, or request the 147C letter from the IRS (faster, obtainable by phone).

5. Single-page website with no clear business activity Mercury may check your website. A parked domain or a website with only contact details and no description of what you do raises flags. Fix: Build a simple website (even a single landing page on Squarespace or Webflow) describing what your company does. Costs nothing and significantly improves approval rate.

Mercury Alternatives if You're Rejected

For most non-resident LLC owners, Wise Business is the best backup if Mercury is unavailable — it provides USD, GBP, EUR, and AUD accounts with local routing numbers, fully functional for receiving and sending business payments.

Annual Compliance Note

• Having a Mercury account does not replace your US tax obligations. Your Wyoming or Delaware LLC still requires:
• Annual state report ($60/year Wyoming; $300+ Delaware)
• Form 5472 + pro-forma 1120 (for foreign-owned single-member LLCs): due annually, $25,000 penalty per form for non-filing
• A US CPA to file these ($500–1,500/year)

Do not confuse "I have a bank account" with "I'm compliant." Get a US CPA as soon as your LLC is operational.

FAQs

Can I use a non-US address for my Mercury account? Yes. Mercury explicitly supports international founders. The application accepts non-US residential addresses for the account owner. The business address should be your LLC's registered address in the US (your registered agent's address).

Does Mercury provide a SWIFT code for international transfers? Yes. Mercury provides a SWIFT code for international wire transfers. USD wires go out same or next business day. International currency conversions (sending EUR from a USD account, for example) involve Mercury's FX rate — compare with Wise for large transfers.

Can I have multiple Mercury accounts? Yes — one per LLC. If you have both a Wyoming LLC and a Delaware C Corp, you can have a Mercury account for each (separate applications).

Is Mercury safe for large balances? Mercury is FDIC-insured to $250,000 directly. Through its Vault feature and sweep network, balances up to $5M are covered. For balances above $5M, maintain multiple banking relationships.

Does Mercury work with Stripe Atlas? Yes. If you form your company through Stripe Atlas, Mercury is the integrated banking option. Atlas coordinates the Mercury account opening as part of the formation package.
