How I Opened a U.S. Business Account With Mercury as a Non-US Founder

Part of the Little Finance House non-US founder series. If you are still at the company-formation stage, start with Can a Non-US Resident Start a U.S. Business in 2026?.

There are many reasons people outside the United States may want to operate a U.S. company today. It could be an influencer or YouTube business, a Shopify store, a dropshipping business, a domain reseller, a SaaS platform, or eventually a much larger international company. In my case, the reason was simple: I wanted a U.S. company for international business and for dealing with U.S. customers and services.

Most people already know that you do not need to be a U.S. citizen to own and operate a U.S. company. The formation process can be handled online, and there are many ways to do it. You can use freelance platforms such as Fiverr or Upwork, formation services such as Bizee or Northwest, or all-in-one services such as Doola or Firstbase. You can choose the route that fits your business.

But forming the company is not the point of this article. A company alone cannot operate the entire business.

You have to pay suppliers. You have to pay subscription fees. And, most importantly, you need to receive money from sales.

As a SaaS platform owner, I could not go much further without a U.S. business account. The challenge was that I am a non-U.S. resident. Opening a traditional bank account in person was not a practical option for a startup like mine, and many alternatives came with business-address, country, or compliance requirements.

Mercury made this part much easier for me. Mercury is a financial technology company, not a bank; banking services are provided through its partner banks.

Opening a Mercury business account as a non-US founder

The process is straightforward when you already have the company information and documents ready. Before starting, I recommend having a working business website, a business email address, a phone number, and your Employer Identification Number (EIN) available.

If you still need an EIN, read How to Get an EIN Without an SSN or ITIN. I will also publish a separate guide showing how to set up a complete business website for a U.S. company.

What I needed for the Mercury application

These were the main items I needed during the application process:

1. First name and last name

2. Work email address

3. Legal business name

4. Legal business address

5. Employer Identification Number (EIN)

6. Proof of the legal business / formation document

7. EIN document from the IRS

8. Operating address

9. Company representative information

10. Country of residence

11. Proof of identity

12. Proof of residential address

13. Business website

14. Business purpose and expected activity

If you have already formed the U.S. company, most of this information should already be available to you.

Legal address and operating address are not the same thing

The first important point is the legal company address. In the application flow, Mercury allows the principal address shown on the formation document, if there is one, or the street address of the registered agent. A P.O. box, virtual address, or mail center is not the same thing as the legal address Mercury is asking for.

The second important point is the operating address: the place where you actually work day to day. This should not simply be your company mailing address, a virtual mailbox, a P.O. box, or your registered agent’s address.

A common mistake is assuming that because the legal entity is registered in the United States, the operating address must also be in the United States. That is not necessarily the case. If you operate the business from another country, use the real, verifiable physical address where you actually work, subject to Mercury’s current eligibility requirements.

Country eligibility matters

There are also country restrictions, prohibited-country rules, and sanctions requirements. If you are residing in a country Mercury does not support, that can prevent you from applying. The countries where the business operates and sends or receives money also matter during compliance review.

In my own case, my country of citizenship appears on Mercury’s prohibited-country information, but I live in a country that Mercury supports. My application was accepted based on my actual residence and the rest of the business information I provided.

This is an area where you should check Mercury’s current country rules when you apply, because eligibility can change.

Some business types may not be supported

Mercury does not support every type of business. Some industries may be prohibited, while others can require additional review.

During the application, Mercury asks whether the company falls into certain business categories. Answer this based on what the business actually does today. If none of the listed categories applies to your company, select the appropriate answer. Do not add speculative future activities simply because you might consider them one day.

Where will you send or receive money?

This was another important part of the application. Mercury asks about the countries where the company operates and where money may be sent or received.

Restricted or sanctioned countries can make an application more complicated or prevent certain activity. The right approach is to provide the real countries involved in the business and let the compliance team review the application based on accurate information.

A live business website helped make the business clear

One thing I strongly recommend is having a real, live website that clearly explains what your company does. I would not apply with only a “coming soon” page or a single generic page that does not explain the actual business.

Your website should make it easy for someone reviewing the application to understand the product or service, who the company serves, and how the business operates.

My Mercury approval timeline

After completing the application and answering the questions honestly, my application moved very quickly.

About half an hour after I applied, I received an email asking for additional address verification. I provided the requested information, and my account was approved shortly afterward.

In my case, the entire process took about an hour, not even a full day.

What I learned from the process

For me, the most important preparation was not finding a shortcut. It was having the business ready: the U.S. company, EIN, formation documents, a real operating address, identity documents, a live website, and a clear explanation of what the company does.

The legal address and operating address questions are especially important for non-U.S. founders. Use the address that matches what Mercury is actually asking for rather than assuming every address has to be in the United States.

The same applies to business activity, expected account usage, and countries involved. Keep the answers accurate and consistent with the real business.

Final thoughts

A U.S. company by itself is only one part of building an international business. You still need a way to receive revenue, pay suppliers, pay subscriptions, operate a website, handle payment processing, keep accounts, and maintain compliance.

For me, opening a Mercury business account solved one of the biggest practical problems after forming the U.S. company. The process was online, the information requested was clear, I completed the additional address verification, and the account was approved in about an hour.
