Do I need a separate address for my LLC?

Not by law, in the jurisdictions we read. A home address is accepted in the principal office and mailing fields wherever the form has them. The reason many owners use a separate address is that the registries we read publish those fields. If you use your home address, it becomes a public record in each of the seven jurisdictions whose form asks for a principal office or mailing address, and scrubbing it later is difficult.

Can I use my residential address for LLC?

Yes, in whichever of the principal office and mailing fields your state's form has. You can also use it in the registered office field if you act as your own registered agent, which requires you to be at that address to accept service; Wyoming's statute says the agent must be 'physically present'. Delaware's 2025 rule bars an agent from operating solely through a virtual office or mail forwarding, and Wyoming's Secretary of State lists mail forwarding locations and virtual addresses as unacceptable for a registered office.

What if I don't have a physical address for my business?

Fill the slots separately. A commercial registered agent covers the registered office field in your formation state. A commercial business address covers the principal office and mailing fields where the form accepts a street address you do not occupy. Where the form allows a PO Box, as Texas and Florida do for the mailing address, a PO Box covers that field. Read your state's row in the table before choosing, because Delaware and Texas do not ask for a principal office at formation and California does.

Does my registered agent's address count as my business address?

It counts as the registered office, which is what the field asks for. Whether it can also go in the principal office or mailing field depends on the agent's terms and, in some states, on the form. Texas and Delaware say the registered office need not be a place of business, but neither statute says the reverse, that the agent's address may serve as the principal office. Ask the agent before filing, and expect the IRS and the bank to want an address where the company can receive correspondence.

Is a virtual address a physical address?

For formation forms, the question is whether the address is a street address as opposed to a PO Box, and a commercial business address at a real building is a street address. Whether the state also requires that someone from the company be present there is a different question, and for the principal office field none of the statutes we read requires it. For the registered office field, Wyoming and Texas do require a person present to accept service, and Delaware bars an agent from working solely through a virtual office.

Does an LLC Need a Physical Address? Only One Slot Needs a Street Address With Someone There

Q: Can I start an LLC without a physical address?

Yes, if 'physical address' means a place where you or your staff are present. The formation filing needs a street address in the registered office slot, and a commercial registered agent supplies that address. The principal office and mailing fields, where the form has them, accept a commercial street address in all seven jurisdictions we read, and California additionally requires its designated office to be inside the state. Texas and Florida accept a PO Box for the mailing address.

Short answer

An LLC needs an address on its formation filing, but only the registered office has to be a street address where someone is present to accept legal papers. That address belongs to the registered agent, and in New York the Secretary of State fills the role, so naming an agent is optional. The principal office field asks for a street address in California, Florida, and the District of Columbia, and does not appear on the Delaware, Texas, or New York forms. New York asks instead for a post office address where the Secretary of State mails process, and Wyoming's form asks for the principal office as item 5 even though the statute's list for the articles does not. The mailing address field is the one most often allowed to be a PO Box. The table below shows what each form asks for, with the statute or form behind each cell.

Key takeaways

The street address that must have someone present lives in the registered agent slot. In each jurisdiction we read that requires a registered office, five states and the District of Columbia, that office must be a street address where the agent can be served in person. That address belongs to the agent, and a commercial registered agent supplies it. California, Florida, and the District of Columbia also ask for a street address for the principal office, without requiring anyone to be there.
New York drops the requirement. LLC Law section 301(b) makes the Secretary of State the agent for every LLC, and section 302(a) says an LLC 'may' add a registered agent. The articles ask for a county and a 'post office address within or without this state' where the Secretary of State will mail process.
Delaware's certificate of formation has one address field, the registered office (6 Del. C. section 18-201). The state's own form has no principal office line and no mailing address line.
Where a principal office field exists, the rules vary. The last paper Form LLC-1 in California labeled the field 'Designated Office in California' and said 'Do not enter a P.O. Box'. Florida asks for 'the street and mailing addresses of the company's principal office'. Texas collects a mailing address that 'may be a post office box or street address' and takes the principal office later, on the Comptroller's Public Information Report.
The IRS asks for a mailing address on Form SS-4 and a street address 'only if different'. The bank identification rule, 31 CFR 1020.220, requires 'a principal place of business, local office, or other physical location' for a company. The rule never uses the words 'P.O. box' or 'physical address'.
A commercial business address fills the principal office and mailing fields where the form accepts a street address you do not occupy. It does not fill the registered agent slot, and save office does not sell registered agent service.

Before you start

Every quoted phrase in this guide comes from a statute, a uniform act, a state form, or an agency page we read on August 25, 2026, or from an archived copy where the agency's site refused the request. Section numbers are inline, and the sources list at the end links to the primary statutes, forms, and agency pages for the seven jurisdictions.
We cover Delaware, New York, California, Texas, Florida, Wyoming, and the District of Columbia. If you are forming elsewhere, the three-slot structure still applies, but read your state's form before relying on any row of the table.
save office sells business addresses and does not sell registered agent service or LLC formations. Where the product is relevant, we say so in one section and keep it out of the rest.

Who this is for

First-time filers who have read that an LLC needs a physical address and want to know which field on the form that sentence is about.
Home-based owners deciding whether the address on the formation document has to be the place where they work.
Non-resident founders with no US address at all, working out which slots a registered agent covers and which ones a business address covers.

Search for whether an LLC needs a physical address and the first page answers in one voice. On August 25, 2026, the results we opened said that a physical street address is required in all fifty states, or in most of them. One said you must have a street address to register.

A five-year-old Reddit thread sat above all of them. The statutes say something narrower, and the difference matters if you work from home, travel, or live outside the United States. A formation filing has up to three address slots, and the strict rule, a street address where someone is present to accept legal papers, applies to one of them. That slot belongs to the registered agent, and the address in it does not have to be yours. This guide walks through the three slots, reads what seven formation forms ask for, and follows the address into the IRS and bank paperwork that comes next.

The three address slots on an LLC filing

Formation documents collect addresses for different jobs, and the rules attach to the job, so it helps to name the slots before reading any form.

The registered office is where the state and the courts can hand legal papers to your company. Where a state requires one, it has to be inside the formation state, it has to be a street address, and someone, the registered agent, has to be there to accept service of process. The Uniform Limited Liability Company Act, in its 2013 version, a model statute that some states have adopted in whole or in part, describes this in section 201(b)(3) as 'the name and street and mailing addresses in this state of the company's registered agent', and section 115(b) requires the agent to have 'a place of business in this state'. New York is the exception, covered below.

The principal office is the company's main executive office. The same uniform act defines it in section 102(16) as 'the principal executive office of a limited liability company or foreign limited liability company, whether or not the office is located in this state'. Whether the formation form asks for it, and whether it has to be a street address, varies by state.

The mailing address is where the state sends correspondence. It is the slot most often allowed to be a PO Box, and on some forms it is the only address the state wants from you apart from the agent's.

Our guide to the three business addresses every LLC needs maps these slots across the forms you fill out after formation. This article stays on the formation document and on the question of which slot has to be physical.

What 'physical address' means on a form

The phrase does three jobs in the pages that rank for this question, and keeping them apart clears up most of the confusion.

The first meaning is a street address as opposed to a PO Box. This is the meaning the formation forms use. When California's last paper form said 'Do not enter a P.O. Box' and Florida's filing instructions say a PO Box 'is not acceptable' for the registered agent, they are drawing this line.

The second meaning is a place where someone is present. For the company itself, none of the formation statutes we read requires that. Delaware's registered office 'may but need not be a place of its business in the State of Delaware' (6 Del. C. section 18-104(a)(1)). Texas says the registered office 'is not required to be a place of business of the filing entity' (Business Organizations Code section 5.201(c)(2)). California's designated office 'need not be a place of its activity in this state' (Corporations Code section 17701.13(a)(1)). Where a presence rule exists, it applies to the registered agent: Texas adds that the registered office 'may not be solely a mailbox service or a telephone answering service' (section 5.201(c)(3)), and Wyoming requires the agent to be 'physically present'. Those are rules about who is there, and they say nothing about the address format.

The third meaning comes from USPS data, where an address carries a commercial or residential delivery type and may carry a Commercial Mail Receiving Agency registration. Formation forms do not read that data. Some banks and platforms do, and our guide to what a virtual business address is covers how those records work.

One wrinkle is worth knowing. USPS offers Street Addressing for PO Boxes, which lets a box holder write the Post Office's street address plus the box number as their mailing address. That produces something that looks like a street address. It still fails the registered office test in Wyoming and Texas, because no agent is physically present at the Post Office counter to accept service.

What each of the seven formation documents asks for

We read the formation statute and, where the state still publishes one, the formation form for seven jurisdictions. Each row shows the address fields on the formation filing itself, before any annual or biennial report.

Jurisdiction	Registered agent slot	Principal office field	Mailing address field	Where the rule lives
Delaware	Required. Street address of the registered office in Delaware, which 'may but need not be a place of its business'	None. The certificate lists the name, the registered office and agent, and anything else the members choose to add	None on the certificate	6 Del. C. sections 18-201 and 18-104, including subsection (k) on the street address format; Division of Corporations LLC formation form
New York	Optional. The Secretary of State is the agent for every LLC; an LLC 'may' also name a registered agent with an address in the state	None on the articles. A county must be named	Required as the 'post office address within or without this state' where the Secretary of State mails process	LLC Law sections 301(b), 302(a), and 203(e)
California	Required for an individual agent. Street address of the agent for service of process; the last paper form said 'Do not enter a P.O. Box'. A corporate agent lists its name only	Required. The statute asks for 'the street address of the initial principal office'; the last paper form labeled the field 'Initial Street Address of Designated Office in California' and banned PO Boxes	Optional, 'if different' from the office address	Corporations Code sections 17702.01(b) and 17701.13(a); Form LLC-1 (formation is now online only)
Texas	Required. Street address of the registered office where the agent can be personally served; 'may not be solely a mailbox service or a telephone answering service'	None on the certificate. The principal office is reported later to the Comptroller on the Public Information Report	Required. The 'initial mailing address', which 'may be a post office box or street address'	Business Organizations Code sections 3.005(a) and 5.201(c); Tax Code section 171.203; Form 205 instructions
Florida	Required. Name, 'street address in this state', and written acceptance of the agent; the filing instructions say a PO Box 'is not acceptable' here	Required. 'The street and mailing addresses of the company's principal office'	Required, and the filing instructions say 'a PO Box is acceptable for the mailing address'	Fla. Stat. sections 605.0201(2) and 605.0113; Sunbiz filing instructions
Wyoming	Required. Street address of the registered office, 'a physical location where the business entity's registered agent ... is physically present at that location'	Asked for on the form as item 5, and again on the annual report. The statute's list for the articles names only the registered office	Asked for on the form as item 4	W.S. sections 17-29-201(b), 17-28-101(a)(i), and 17-29-209; Secretary of State articles form and FAQ

'The street and mailing addresses of the initial principal office', which may be outside the District	Required alongside the principal office street address	D.C. Code sections 29-802.01(b), 29-101.02(35), and 29-104.03

Address fields on the LLC formation filing in seven jurisdictions, from statutes, published forms, and agency instructions read on August 25, 2026. Annual and biennial reports add fields of their own and are covered separately.

Where the unanimous answer comes from

Six of the seven rows have a street address in the registered agent column. That is the fact behind the page-one consensus, and for those six it holds. What the consensus leaves out is two things. The address in that column is the agent's business address, which a commercial registered agent provides as part of the service, and New York has no such requirement because the Secretary of State is the agent. The statutes in Delaware and Texas say in as many words that the registered office does not need to be a place where the company does business. California says the same about the in-state office it requires every LLC to designate.

Delaware is the clearest case. Section 18-201 of the LLC Act says the certificate of formation 'shall' set forth the company name, 'the address of the registered office and the name and address of the registered agent', and 'any other matters the members determine to include'. The Division of Corporations' own form has one address line, for the registered office. There is no principal office field and no mailing address field to fill with anything, physical or otherwise.

New York goes further and makes the agent optional. Section 301(b) says no LLC may be formed unless its articles designate the Secretary of State as agent for service of process, and section 302(a) says the company 'may', in addition, designate a registered agent. The articles then ask for 'the post office address within or without this state to which the secretary of state shall mail a copy of any process'. The statute says post office address. We could not confirm from the Department of State's own pages whether it accepts a PO Box in practice, so we report the statute's words and stop there.

California is the state that comes closest to requiring an in-state office. Section 17701.13(a) says every LLC 'shall designate and continuously maintain in this state' an office 'which need not be a place of its activity in this state', plus an agent. The formation statute, section 17702.01(b)(3), asks for 'the street address of the initial principal office and the mailing address of the limited liability company if different'. The last published paper Form LLC-1 printed that field as 'Initial Street Address of Designated Office in California' with the note 'Do not enter a P.O. Box'. California now takes formations online only, for $70, and we could not check the on-screen label behind the login, so we quote the statute and the last paper form.

Texas splits the addresses across two agencies. The certificate of formation collects the registered office and, since January 1, 2022, an 'initial mailing address', which the Secretary of State's instructions say 'may be a post office box or street address'. The principal office does not appear on Form 205 at all. It is reported to the Comptroller on the Public Information Report, where Tax Code section 171.203(a)(5) asks for 'the address of the ... principal office and principal place of business'.

Wyoming shows why it pays to read the form and the statute together. Section 17-29-201(b) lists only the registered office and agent for the articles. The Secretary of State's form adds item 4, 'Mailing address of the limited liability company', and item 5, 'Principal office address', and the annual report under section 17-29-209 asks for the principal office again. The statute's hard rule sits on the registered office, which must be 'a physical location where the business entity's registered agent ... is physically present at that location'. The list of what does not qualify, 'Post office boxes, drop boxes, virtual addresses, mail forwarding locations, UPS or FedEx stores', comes from the Secretary of State's FAQ, so cite it as agency guidance rather than as statute.

California is not the only state with an in-state office slot

Massachusetts asks for 'the address of the office in the commonwealth' that its LLC statute requires (General Laws chapter 156C, section 12(a)(2)), an in-state office requirement that sits beside the agent requirement much as California's designated office does. We read the Massachusetts statute but did not verify filing practice there, so treat that sentence as a pointer to check rather than a settled answer.

Can you start an LLC with no physical address at all?

Yes, in the sense the question is usually asked. A founder with no US address, or a US founder who does not want a home address on any form, can fill every slot on the filings above without renting an office.

The registered agent slot is filled by a commercial registered agent. The agent's business address goes in the registered office field, which is what the field was designed for. The agent has to be a real presence in the state. Delaware made that explicit in 2025: a bill that took effect on August 1, 2025, added section 18-104(e)(2), under which a registered agent 'may not perform its duties or functions solely through the use of a virtual office, the retention by the agent of a mail forwarding service, or both'. That rule governs how the agent operates. It says nothing about the addresses an LLC uses elsewhere, on IRS and bank forms or in the principal office and mailing fields of states whose forms have them.

The principal office and mailing fields, where the form has them, take a street address the company uses for business, or in the mailing field a PO Box where the state allows one. Delaware, Texas, and New York do not ask for a principal office on the formation document; New York asks instead for a post office address where the Secretary of State mails process. Florida, Wyoming, and the District of Columbia ask for a principal office address and, in DC's case, define it as an office that may be outside the District. California asks for a designated office inside the state. Arizona, which is outside our seven, says outright what the Texas and Delaware statutes leave unsaid: the principal address may 'be the same as the mailing address of the company's statutory agent' (A.R.S. section 29-3201(B)(2)).

The practical sequence for a founder with no address is to pick the state, engage a registered agent there, and then decide what goes in the principal office and mailing fields based on that state's row in the table. Our registration guide for non-residents covers the order of the other decisions, and the registered agent versus business address guide explains why the two addresses are usually different.

If you use your home address, here is what becomes public

A home address is a street address, and each form in the table that has principal office or mailing fields accepts one there. Delaware's form has neither field, and Texas has no principal office field. What you give up is privacy. The seven registries in this guide publish formation filings, and the address fields on them are searchable.

Delaware's certificate does not carry your address unless you are your own registered agent. New York publishes the address where the Secretary of State mails process. Florida, Wyoming, and the District publish the principal office address, and Texas publishes the mailing address on the certificate and the principal office on the Public Information Report. Our guide to using your home address for an LLC covers what each registry shows, and our count of how often a registered agent hides a home address measured the gap with real filings.

If the plan is to change the address later, know that the change touches more than one record. The state filing, the IRS, the bank, and your vendors each hold a copy, and our address change guide lists the order to update them in.

How to get a physical address for your LLC without renting an office

Four options cover the slots above, and each one fits some fields and fails others.

Option	Registered agent slot	Principal office field	Mailing address field
Commercial registered agent	Yes. This is the service	Sometimes. Some agents allow their address here and some do not; ask before filing	Sometimes, on the same terms
Commercial business address (what save office sells)	No	Yes, where the form accepts a street address the company does not occupy	Yes, on every form in this guide that has the field
PO Box	No, in all six rows of the state table that require an agent	No on forms that ask for a street address	Yes in Texas and Florida; check the form elsewhere
Coworking membership or shared office	No, unless the operator also acts as agent	Yes, if the operator allows the address on state filings	Yes, if mail service is included

Which option fills which slot, based on the statutes and forms in this guide. 'Sometimes' rows depend on the provider's own terms, which vary.

Where save office fits

save office provides a commercial street address in US cities including New York, San Francisco, Tampa, Washington DC, Wilmington in Delaware, and Cheyenne in Wyoming. The address is built for the principal office and mailing fields, and it is active within 24 hours of sign-up. save office is not a registered agent service, so the registered office slot still needs an agent in your formation state. Before you put any address on a filing, the address checker shows how USPS classifies it.

The IRS and the bank ask their own address questions

The application for an EIN, the federal tax ID, is the next form most founders touch, and its instructions draw the same street-versus-mailing line. Lines 4a and 4b of Form SS-4 take 'the mailing address for the entity's correspondence'. Lines 5a and 5b take the street address 'only if different from its mailing address', and the instructions add 'Don't enter a P.O. box number here'. Line 6 asks for the county and state of the entity's primary physical location. So the IRS does not require a separate street address, but it does ask where the business is.

The bank works under a different rule. Under 31 CFR 1020.220(a)(2)(i)(A)(3), a bank's customer identification program must collect an address that, for a company, is 'a principal place of business, local office, or other physical location'. The rule never uses the words 'P.O. box' or 'physical address'. The contrast with a PO Box comes from the 2004 guidance that FinCEN and the federal banking regulators issued on the rule, which explains that a rural route number, 'unlike a post office box number, is a description of the approximate area where the customer can be located'.

Beyond that federal floor, banks set their own rules about which address types they accept. Some publish them, and some of the published rules exclude commercial mail addresses by category. Our guide to business bank account address requirements reads the published rules bank by bank.

The address you gave at formation is the one the state will write to, and the principal office comes up again on the periodic report in most of the seven. Florida, Wyoming, and the District ask for it on the annual or biennial report, Texas takes it on the Public Information Report, and California takes it on the Statement of Information. New York's biennial statement asks for the address where the Secretary of State mails process, and a Delaware LLC files no annual report at all. Our 50-state annual report guide covers those deadlines.

Can you change the LLC address later?

Yes. Each state in this guide has a filing for it, and the fee and the form differ. California charges nothing for a Statement of Information filed between the regular filing periods to report a change, and Texas records a new principal office on the next Public Information Report or through an address update with the Comptroller. Keeping the registered office and the principal office as separate entries from the start makes the later change smaller: if your own office moves, the registered office entry stays as it is.

The 7-channel address change guide walks through the state, IRS, bank, and vendor updates in the order they have to happen.
