EN — How to Open a Mercury Bank Account for Your US LLC as a Non-Resident (2026)

How to open a Mercury bank account for your US LLC as a non-resident in 2026. Step-by-step guide, required documents, and comparison with Relay and Wise Business.

Your LLC is formed. Your EIN is in hand. The next step — and one of the most anticipated — is opening your US business bank account. Without it, you cannot activate Stripe, receive dollar payments, or pay your US business expenses.

Mercury is the reference US bank account for non-resident LLC owners in 2026. This guide tells you exactly how to open it, what documents you need, and how it compares to Relay and Wise Business.

Why you need a US bank account for your LLC

💡 Answer capsule — Why does a US LLC need a US bank account? A US bank account (Mercury or Relay) is required to activate Stripe, receive dollar payments from clients and platforms, and maintain the legal separation between your personal finances and your LLC. Without a US bank account, your Stripe funds either stay locked in your Stripe balance or get converted at unfavorable rates to a European account. Mercury is free, 100% online, and accepts LLC owners living outside the United States.

Activate Stripe. Stripe requires a US bank account (routing number + account number) to wire your funds. Without one, your payments pile up in your Stripe balance.

Receive dollar payments directly. Clients, Amazon, Etsy, Gumroad, Shopify — dollar payments arrive directly on Mercury. You hold them in USD and convert when the exchange rate is favorable.

Legal separation. One of the fundamental rules for maintaining your LLC's liability protection: never mix personal and business finances. A dedicated LLC account is a legal and practical necessity.

Pay US business expenses. AWS, Notion, Figma, Stripe fees, SaaS subscriptions — all your dollar-denominated business expenses can be paid directly from Mercury, with no conversion fees.

The account is typically approved in 1 to 5 business days after submitting your application.

Step-by-step: Opening your Mercury account

💡 Answer capsule — What documents do you need to open Mercury as a non-resident LLC owner? To open Mercury with a non-resident LLC, you need: (1) Articles of Organization from your state (the LLC formation certificate), (2) Operating Agreement, (3) EIN Confirmation Letter from the IRS (the document confirming your EIN number), and (4) a valid passport for identity verification. All documents are uploaded digitally — no in-person visit, no notarization required.

Step 1 — Go to mercury.com (not the French or localized version)

Navigate directly to mercury.com and click "Open Account". Make sure you are on the English US version.

Step 2 — Create your account

Enter your email address and choose a password.

Step 3 — Enter your LLC information

Mercury will ask for:

Business legal name: your LLC's exact name as it appears in your Articles of Organization
State of formation: Wyoming, Delaware, New Mexico, etc.
EIN: your 9-digit number in XX-XXXXXXX format
Business address: your Registered Agent's address (not your personal address abroad)
Website: your website or product URL
Business description: what your company does (be precise and accurate)

Step 4 — Enter beneficial owner information

Mercury requires information about the beneficial owner (you):

Full name, date of birth
Home address: your actual address outside the US (not the LLC's address)
ID: passport number (Mercury accepts passports for non-residents without a SSN)
Ownership percentage: 100% for a Single-Member LLC

Step 5 — Upload your documents

Upload the following:

Articles of Organization (your LLC formation certificate from the state)
Operating Agreement
EIN Confirmation Letter from the IRS

All documents can be PDFs or high-quality photos.

Step 6 — Identity verification

Mercury will ask for a photo of your passport and sometimes a selfie. This is processed directly in the Mercury interface, typically within minutes.

Step 7 — Wait for approval

Timeline: 1 to 5 business days in most cases. Some accounts are approved within hours; others take longer if additional verification is needed.

Once approved, you receive your routing number and account number immediately. You can connect Stripe within minutes.

Common reasons Mercury rejects an application

💡 Answer capsule — Why does Mercury reject LLC applications from non-residents? Mercury commonly rejects applications for these reasons: prohibited business activities (crypto, gambling, weapons, certain financial services), inconsistencies between the LLC name/EIN and documents, using a personal foreign address instead of the Registered Agent's address as the business address, or an unclear business description. If rejected, Relay or Wise Business are solid alternatives.

Prohibited activities. Mercury does not serve crypto exchanges, gambling, weapons, adult content, or certain financial services. If your business falls into these categories, use Relay or Wise Business instead.

Inconsistent information. Your LLC name, EIN, and address must exactly match your Articles of Organization and EIN Letter. Any mismatch triggers manual review.

Wrong business address. Use your Registered Agent's US address as your business address — not your personal address abroad.

Vague business description. Mercury reviews your business model. "Online business" is not sufficient. Be specific: "B2B SaaS for project management" or "Print-on-demand e-commerce via Shopify" works well.

No website or online presence. Mercury verifies that your business exists. A minimal website with a clear description of your products or services helps significantly.

Mercury vs Relay vs Wise Business: which one?

💡 Answer capsule — Mercury vs Relay vs Wise Business for a non-resident LLC: which to choose? Mercury is the best primary account for most non-resident LLC owners: free, native Stripe integration, clean interface. Relay is better for e-commerce sellers who need multiple sub-accounts to separate revenue streams, marketing budget, and taxes. Wise Business is ideal as a secondary account for multi-currency management and converting USD to EUR/GBP/CHF at interbank rates (~0.4% fee). The recommended setup: Mercury as primary + Wise Business as secondary for FX conversions.

Type	US neobank	US neobank	Multi-currency payment service
Monthly fees	Free	Free (basic plan)	Free (basic plan)
USD account	✅ Yes	✅ Yes	✅ Yes (routing + account number)

Recommended setup:

SaaS or freelancer: Mercury (primary) + Wise Business (secondary for USD→EUR/GBP conversion)
E-commerce: Relay (primary) + Wise Business (secondary for conversions)
Just starting out: Mercury alone — covers 90% of use cases

After Mercury: connecting Stripe

Once your Mercury account is open and you have your routing and account numbers, activating Stripe takes about 15 minutes:

Go to stripe.com (not a localized version)
Select "Company" as entity type, "United States" as country
Enter your EIN and your Registered Agent's address as business address
Link Mercury using routing number + account number
Complete identity verification with your passport

Your Stripe US account is typically activated within a few hours.

FAQ

Can I open Mercury without a US Social Security Number? Yes. Mercury accepts non-residents without a SSN. Your EIN, LLC documents, and passport are sufficient.

How long does Mercury account approval take? Typically 1 to 5 business days after submitting your application. Some accounts are approved within hours.

Do I need to declare my Mercury account in my home country? Yes, in most countries. For example, French residents must declare all foreign bank accounts annually (Form 3916). Check your specific country's requirements.

What if Mercury rejects my application? Try Relay (relay.fi) as a first alternative. Wise Business is also an option, though it is technically a payment service rather than a true US bank. Both accept non-resident LLC owners.

Can I use Wise Business instead of Mercury as my primary account? Technically yes — Wise provides a US routing number and account number compatible with Stripe. But Mercury is generally preferred as a primary account because it is a true US banking service. Use Wise as a secondary account for currency conversions.
