U.S. Phone Number and Address for Foreign-Owned Companies

The short answer

U.S. banks must collect a physical address for a company customer: a principal place of business, local office or other physical location.
Under the CAN-SPAM rules, commercial email must include a valid physical postal address: a street address, a post office box registered with the U.S. Postal Service, or a private mailbox registered with a commercial mail receiving agency.
A U.S. address and phone number do not replace the registered agent required by state law.
Use the same address and number everywhere: documents, bank, payment platforms, website and email.
At MyUSAService, a physical address in Miami with mail management costs $39 per month (price as of September 2026).

Frequently asked questions

A customer who cannot tell where you are or how to reach you hesitates before paying. A bank that cannot verify your address does not open your account. For a U.S. company run from abroad, a U.S. address and phone number are not decoration: they solve practical problems.

This guide separates what the rules require from what is simply good practice.

What the rules require

Banks. A U.S. bank must collect a physical address for a company customer: a principal place of business, local office or other physical location. A post office box does not meet that description. Our guide on opening a U.S. business bank account covers the rest of the verification.

Marketing email. The FTC’s CAN-SPAM rules require commercial email to include your valid physical postal address. It can be your current street address, a post office box registered with the U.S. Postal Service, or a private mailbox registered with a commercial mail receiving agency.

The state. State law requires a registered agent with a physical address in the state. That is a separate role: see our guide on choosing a registered agent.

What is good practice

Reachability. A phone number and a business address make it easier for customers to contact you before and after a purchase.
Clear policies. Shipping, returns and support hours, written on the site, do more for trust than a phone number alone.
Consistency. Payment platforms and banks compare your company details across documents. See why platforms reject accounts.

Setting up the address

A virtual office gives the company a physical street address in the United States and handles the mail. Check that the address is a real street address that your bank accepts, and use it consistently. See our guide to virtual office services for what to compare.

Setting up the phone number

A U.S. phone number can be provided by an internet telephony service and forwarded to a phone anywhere. Choose one that:

Lets you answer or return calls in the hours you publish.
Offers voicemail with email notification.
Lets you keep the number if you change provider.

Publish the hours and the expected reply time. A number that nobody answers does more harm than no number.

Do not overstate your presence

Describe your company accurately. A virtual address is a business address, not a store, and a forwarded number is a contact line, not a call center. Do not imply a physical location, team or stock you do not have.

What MyUSAService offers

Frequently asked questions

Do I need a U.S. address for my U.S. LLC?

The company needs a registered agent with a physical address in its state, and banks expect a physical address for the company. Many non-resident owners use a U.S. address service.

Can I use a P.O. box as my business address?

Banks generally do not accept it as the company’s physical address. For email marketing, the FTC accepts a post office box registered with the U.S. Postal Service, or a registered private mailbox.
