Can a European Open a Mercury Account? Eligibility, Documents and $250 Referral Benefit
Can a European open a Mercury account with a US LLC?
Yes, many European and other non-US founders can apply for Mercury if they have a US-registered company, such as a US LLC, and meet Mercury’s eligibility requirements.
But approval is not automatic.
Mercury reviews the company, the people behind it, the business activity, the address setup and the documents provided during the application. A US LLC can make you eligible to apply. It does not guarantee that Mercury will approve the account.
This guide explains the practical requirements, the documents to prepare and how the current $250 Mercury referral benefit works.
Affiliate disclosure: This article contains a Mercury referral link. If you open an eligible Mercury business account through this link and meet Mercury’s referral requirements, your business may receive a $250 benefit and US LLC Setup may also receive a referral benefit. Account approval, account opening and bonus payment are not guaranteed.

Mercury Eligibility Checklist for European Founders
For European and non-US founders, Mercury eligibility is mainly about the company, the founder profile, the business model and the address setup.
US-registered company
Mercury currently requires the company to be formed and registered in the United States or a US territory.
For European founders, this is often a Wyoming LLC, Delaware LLC or another US-registered entity.
The LLC is the foundation, but Mercury will still review your application.
EIN document
For a US LLC, you should expect to provide an IRS-issued EIN document. Common examples include CP575, 147c or the IRS-returned SS-4.
If your LLC is formed but your EIN document is missing, it is usually better to prepare this before applying. Mercury and other fintech providers typically need the EIN to verify that your US LLC is properly registered with the IRS.
If you are still unsure how the EIN process works as a non-US founder, read our full guide on how to get an EIN for a US LLC as a non-US resident.

Supported country and residence
Mercury supports many international founders, but not all countries or regions.
As of the last review of this article, Mercury’s prohibited list included some countries and regions in or near Europe, including Albania, Belarus, Bosnia & Herzegovina, Croatia, Latvia, Russia, Ukraine and Russian-occupied regions of Ukraine.
This list can change. Always check Mercury’s current official prohibited countries page before applying.
Supported business activity
Mercury cannot support every business type. Unsupported categories currently include money services businesses, adult entertainment, cannabis, internet gambling and trusts.
If your business model is regulated, high-risk or difficult to explain, prepare for more questions.
Clear ownership and control
Mercury needs to understand who owns and controls the company.
You should be ready to provide information for beneficial owners with 25% or more ownership and at least one person with operating control of the business.
What Documents Does Mercury Require?
Mercury’s exact document request can depend on the application, but European and non-US founders should normally prepare:
• official US LLC formation documents
• IRS-issued EIN document, such as CP575, 147c or IRS-returned SS-4
• passport or government ID
• beneficial ownership information
• clear business description
• source of funds explanation
• details about current or planned US operations
Your business description should be specific.
Avoid vague descriptions like “online business”, “consulting”, “digital services” or “ecommerce”.
Instead, explain what you sell, who you sell to, where your customers are located, how you receive payments and why the US LLC is part of your setup.
For US operations, you do not necessarily need a US office. But you should be able to explain the US connection in a realistic way, such as US clients, US payment providers, US vendors, US dollar invoicing, US platforms or planned US commercial activity.
Mercury Address and Proof of Address Requirements
Address requirements are one of the most important parts of a Mercury application for European and non-US founders.
Many founders assume that a registered agent address is enough. That assumption can create problems.
The key point is this:
Your registered agent address is not the same as your real operating address.
For a general explanation of this difference, read our guide on whether you need a US address for your LLC.
For the company physical address, Mercury currently accepts verifiable residential addresses if the company does not have an office yet and verifiable international addresses for overseas customers.
Mercury does not accept a PO box, virtual address, commercial mail receiving agency, mail center or registered agent address as the physical address.
Mercury may request proof of address, such as a government ID, lease agreement, utility bill, bank statement, coworking invoice, tax document or pay stub.
The document should clearly show the company name or beneficial owner’s name together with the full physical address.
How the Mercury Application Usually Works
A Mercury application is a review of your company, ownership, address setup, documents and business model.
A typical process looks like this:
- Check whether Mercury fits your situation.
- Prepare your LLC, EIN, ID, ownership and address information.
- Start through the referral link if you want to use the referral benefit.
- Complete the application with consistent information.
- Upload documents if requested and wait for Mercury’s review.
Do not rush the application. Your LLC name, EIN document, formation document, owner information, business activity, website and address details should all tell the same story.
Common issues that can weaken an application include vague business activity, missing EIN documentation, inconsistent company details, unclear ownership, unsupported industries, an unverifiable address setup, or no realistic explanation of US operations.
How the $250 Mercury Referral Benefit Works
The $250 referral benefit is a useful reason to start through the correct link, but it is not a guaranteed signup bonus.
According to Mercury’s current business referral information, the referred business may qualify for the $250 benefit if:
• the business is a net new Mercury customer
• the account is opened through the unique referral link
• the referred business deposits and maintains at least $10,000 in its Mercury account for at least one full business day during the first 90 days
• all additional Mercury requirements are met
Mercury also states that referrals may receive expedited application review.
Important: expedited review does not mean guaranteed approval.

How US LLC Setup Can Help You Prepare
If you already have a US LLC, EIN, documents and a clear business setup, you may be ready to apply directly.
If you are not ready yet, it may be better to prepare before applying.
US LLC Setup helps European and non-US founders with practical formation support and banking readiness preparation.
This can include Wyoming LLC formation support, EIN application guidance, document handover, operating agreement templates, banking readiness preparation and payment setup orientation in the Premium Launch package.
The goal is not to guarantee Mercury approval.
The goal is to help you start with a cleaner, more consistent setup.

Final Thoughts
So, can a European open a Mercury account?
In many cases, yes — if the founder has a US-registered company, such as a US LLC, and the company meets Mercury’s eligibility, document, address and review requirements.
But a US LLC is not a shortcut to guaranteed banking. A referral link is not a guarantee of approval. And a $250 benefit is not automatic.
The strongest setup is usually the cleanest setup: a properly formed US LLC, a valid EIN document, clear ownership information, a realistic business description, accepted address details and a consistent application story.
