US Address Options at a Glance
PO Box (Prohibited)

Rejected by state Secretaries of State and US banks. Cannot be used for LLC registration.

Registered Agent Address

Accepted by Secretary of State for legal service of process, but rejected by banks as a primary business location.

Virtual Office Address (Best)

Real physical street address with unique suite number. Accepted by Mercury/Relay banks & forwards physical mail.

1. Why USPS PO Boxes Are Prohibited for US LLCs

State corporation laws across Wyoming, Delaware, and all 50 US states explicitly require an LLC to maintain a physical street address.

A Post Office Box (PO Box) is legally rejected because process servers cannot hand-deliver legal court summons or lawsuit notices to a PO box container.

2. Using Your Registered Agent Address: Pros and Limits

Your Registered Agent provides a physical street address to satisfy Secretary of State statutory rules.

However, Registered Agents only handle official state legal mail. They will not accept customer returns, supplier packages, or bank debit cards.

3. Commercial Virtual Offices with Mail Forwarding

A Virtual Office Address gives your foreign LLC a real commercial building address with a unique suite number (e.g., "1209 North Orange St, Suite 400").

Digital mail forwarding services scan incoming letters into high-resolution PDFs and forward physical bank cards directly to your foreign home address.

5. Understanding USPS Form 1583 Notarization

Under US postal regulations, setting up a virtual mailbox requires completing USPS Form 1583 (Application for Delivery of Mail Through Agent) and providing two forms of ID. Online notarization services allow foreign founders to complete Form 1583 remotely via video call.
