Which address goes where on an LLC filing, and what a virtual office is accepted for, by state

The registered agent address

Wyoming is the worked example. W.S. 17-28-101 requires each business entity to keep a registered office at a street address in Wyoming. That office must be a physical location where the registered agent, or a person with an agency relationship to the agent, can accept service of process and is physically present. Every Wyoming LLC must maintain that office and an agent, and its articles of organization must state the initial office's street address and the initial agent's name. The statute lets the registered office be the same as any of the entity's places of business, and the agent must maintain a physical address.

The Private Pierce table has not yet researched what the registered-agent address means for service of process in any of the 51 jurisdictions it covers. What it does record is how each state treats the address in that field. As of 2026-09-30, Oregon says the registered agent's publicly available address may not be a PO box, a CMRA, a mail-forwarding business or a virtual office. Washington says a PMB or CMRA address cannot be the registered office, and a PO box may be given for notice in addition to the required physical address. Texas requires a street address where process may be personally served, and says the registered office may not be solely a mailbox service. Wyoming's row says a PO box is acceptable only when listed in addition to the required physical address, and that CMRA treatment is not addressed in the reviewed formation sources. These four states do not all give the same answer, and Wyoming's row has a gap.

The principal office

The principal office is a separate field with a separate rule. Wyoming's annual report asks for the address of the LLC's principal office. The Wyoming articles carry a principal office address field, and the reviewed sources do not say how that field treats a PO box, a CMRA or a street address. The table's rule is that a gap stays visible and is not read as a yes or a no.

Other states say more. California's principal office street-address field rejects PO boxes, and the principal office may use a legitimate street-address CMRA or PMB that otherwise meets California's filing requirements. Washington requires a physical street address and does not accept PO boxes or PMB or CMRA addresses there; the address need not be in Washington. Oregon says the principal office may not be a PO box, a CMRA, a mail-forwarding business or a virtual office. Georgia's field accepts a post office box.

The mailing address

The mailing address is the field the filing labels as the mailing address, and nothing more. The table warns that the label is easy to overread: it is not a finding about where the LLC operates, where records are kept, where the registered agent is located, or which address appears publicly. California's LLC-12 permits a PO box or an in-care-of address. Georgia's mailing field accepts a post office box as well. Wyoming's articles include a mailing address field, and the reviewed sources do not address its PO box, CMRA or street-address treatment.

Some forms add a fourth question: the address of an organizer or member. Acceptance there does not carry over to the principal office, the mailing address or the registered agent. Texas Form 205, for example, permits a street or mailing address for governing persons and the organizer rather than requiring a street-only address.

What a CMRA is, and what a label is not

The postal side is narrow. USPS defines a CMRA as a business accepting U.S. Mail for another person or entity as a business service. Delivery requires PS Form 1583 for each PMB addressee, with acceptable primary and secondary identification. The address must be designated with PMB or # and the mailbox number. The operator must keep a digital copy of the completed form at its business location for Postal Service examination.

Terms such as virtual mailbox, business address or mail service are marketing labels, and a label is not the evidence; the question is whether the service sits inside the CMRA framework. A CMRA label does not by itself promise anonymity, filing acceptance or removal from public records.

How much the table knows

On 2026-11-03 the page stated that the table covers 51 jurisdictions and 663 cells. By the page's own count, 374 are confirmed facts, 283 are dated typed unknowns and 6 are withheld pending confirmation. A typed unknown is not a yes or a no. Every cell cited in this guide is dated 2026-09-30, and the page notes that registry fields and acceptance rules change with statutes, forms and agency practice.

What stays visible afterwards

Acceptance and visibility are separate questions. On the registered agent's address, the table reported on 2026-11-03 that 46 of 51 jurisdictions' live Secretary of State portals confirm it is displayed; the rest are not yet independently observable, which is not a confirmed no. For the principal office, the mailing address and the organizer or member address, it says public display is not yet covered by reviewed evidence. Three companion pages cover who prints where: Registered Agent Visibility by State, Organizer Name Visibility by State and Member Name Visibility by State. The organizer page keeps a filing requirement and present public access as separate fields, and the member page tracks whether a state requires member names at formation separately from whether they are publicly visible.

Questions to ask before an address goes into a field

These are questions for the state's filing office or a filing service.

• Which field is this, and what does the form call it?
• Does this field accept a PO box, a CMRA or PMB address, or only a street address?
• Does the state describe the registered office as a physical location where someone is present to accept papers?
• Which of these addresses prints on the public record, and where?
• What is the source for the answer: a statute, a form or an instruction page?

To read your own state, open its row in each of the table's four sections and follow the row's source.
