Key takeaways
- Two LLCs can share one address, and so can ten as far as the published state rules go. We looked where a cap would live, in the state registered office and registered agent rules, and did not find one. The published rules govern what kind of address it is, not how many businesses use it.
- The question lands in a different place depending on the business. For an LLC it lands on the Secretary of State, for a DBA it usually lands on a county clerk, and for an unregistered sole proprietor there is no state layer to answer it at all.
- Register each business as its own named recipient and keep separate bank accounts and records. A shared address by itself does not set aside liability protection, but Associated Vendors, Inc. v. Oakland Meat Co., 210 Cal. App. 2d 825 (1962), the California decision that courts continue to cite for the alter ego factor list, includes the use of the same office or business location on that list. Factor lists vary by state.
- A shared address and a Google Business Profile are different questions. Google's published test for two profiles at one address is different names plus clearly visible differences in signage, not different categories, and a rented mailing address you do not operate from is ruled out on eligibility before that test even applies.
Before you start
- Have each business's exact legal name ready, since you register every one as its own recipient at the shared address.
- Know which filing layer each business sits in, because a DBA and an LLC ask for the address in different places and on different forms.
- Plan separate bank accounts and bookkeeping for each entity before mail starts arriving for several businesses at once.
Who this is for
- Serial founders and small business owners running more than one LLC.
- Anyone running several DBAs or trade names, whether under one LLC or as a sole proprietor.
- Real estate investors or brand owners who want several entities at one professional address.
- Owners with businesses registered in more than one state.
How many LLCs can you have at one address? As many as you register, as far as the published state rules go, and two is no different from ten. We went looking for a state that caps it and did not find one. The catch is separation. Each business has to be set up and run as its own thing, and registered separately wherever its type requires a filing, or a shared address becomes a liability instead of a convenience.
The other half of the answer is that the question usually gets asked about LLCs, and "business" is doing a lot of work in it. An LLC, a DBA, and an unregistered sole proprietorship do not even ask about the address in the same place, which is why the same question gets different answers depending on who is answering.
This guide covers where the limit question lands for each business type, how a shared address differs from a holding company, how to keep each business's mail and records distinct, the two places a shared address genuinely shows up for an entity, what Google's published rule says about two listings at one address, and what changes when your businesses are spread across different states.

How Many LLCs Can Share One Address? We Went Looking for the Limit
If a state capped the number of businesses at one address, the cap would live in the registered office and registered agent rules. That is where we looked, and what we found instead was that states regulate what kind of address it is, not how many businesses use it.
- Delaware and Wyoming both publish entity counts, and both point the other way. In Wyoming the threshold is more than ten (W.S. 17-28-101(a)(ii)(D)). In Delaware a registered agent serving more than 50 entities becomes a "commercial registered agent" and picks up extra obligations of its own, including a Delaware business office generally open during normal business hours (8 Del. C. 132(c)). That is a threshold that loads duties onto the agent. It is not a ceiling on you, and crossing it stops nobody.
- Texas publishes what the address cannot be, not how many can use it. A registered office must be a physical address in Texas where the agent can be personally served during business hours, and it "cannot solely be the address of a mailbox service or telephone answering service" (Texas Secretary of State, formation FAQs).
- California sets no number at all, and goes the other way on location: an LLC designates an office that "need not be a place of its activity in this state" (Corporations Code 17701.13(a)).
What we checked, and what we did not
We read the Delaware registered office and registered agent subchapter, the Texas Secretary of State formation FAQs, and the California LLC statute, and none of them counts entities. We did not read all fifty state codes, and we did not read county or municipal ordinances, where home-occupation and local business-license rules are a separate layer we have not surveyed. So the honest scope is this: at the state level, in the place a cap would live, we did not find one.
Plenty of serial founders, real estate investors, and people running a few brands operate every business from a single professional address. What matters is that each one is genuinely its own business.
- Each LLC is formed separately, with its own articles of organization, its own state registration, and its own EIN (Employer Identification Number) where one is required.
- The shared address goes on each entity's filings, but the entities themselves stay distinct.
- Sharing an address is an operational convenience, not a merger of the businesses.
"Two Businesses" Is Three Different Questions
Most answers to this question assume both businesses are LLCs. Often they are not, and the layer the question lands in changes completely depending on what you are actually running.
| Business type | Who you file the address with | What the form asks for |
|---|---|---|
| LLC | Secretary of State | A designated or registered office, which in California "need not be a place of its activity in this state" |
| DBA / fictitious business name | Usually a county clerk, though it varies: New York sends corporations, LPs, and LLCs to the Department of State while individuals and partnerships go to the county clerk, and Florida files at the state level through Sunbiz | In California, "the street address, and county, of the registrant's principal place of business in this state" |
| Unregistered sole proprietorship | Nobody, at the state level | Nothing. Texas, for example, confirms a sole proprietorship files no formation document with the Secretary of State, which leaves a DBA filing or local licensing as the places the address comes up |
Where the address question lands, by business type. Filing layers and fees are state specific, so confirm with your state and county before filing.
That middle row is the part that catches people. An LLC's office slot is explicitly allowed to be somewhere the company does not operate. A California DBA asks a different question: it wants the street address of the registrant's principal place of business in the state (Business and Professions Code 17913(b)(2)). That is a factual assertion about where the business is principally located, not a mailing slot, and answering it with an address you do not operate from is a different act than putting that address on an LLC filing.
A few more differences matter once several trade names sit at one address.
- A DBA can come with obligations tied to the premises. New York requires a certified copy of the certificate to be "conspicuously displayed on the premises at each place in which the business for which the same was filed is conducted" (General Business Law 130(4)), which is awkward if the address is one you do not staff.
- A shared address does not anonymize a sole proprietor the way it can an entity. New York's certificate requires the full name and residence address of each person conducting the business, and county clerks maintain an alphabetical index of the certificates.
- California adds a publication step LLCs do not have: a fictitious business name statement has to be published in a newspaper of general circulation within 45 days of filing, with an affidavit filed back with the county clerk (Business and Professions Code 17917).
- The closest thing to a published limit anywhere in this topic is per application, not per address. Florida instructs filers not to enter more than one fictitious name on an application, so each brand is its own filing and its own fee.
The per-entity cost stack does not transfer to DBAs
Everything below about EINs, mail authorization, and state fees is a per-entity story. A sole proprietor needs only one EIN no matter how many trade names they operate under (Instructions for Form SS-4, Rev. 12/2025). If your "two businesses" are two DBAs rather than two LLCs, most of that stack collapses to one. Whether to split them into separate LLCs at all is a liability question rather than an address question, and it is covered in multiple businesses under one LLC.

Shared Address vs Holding Company: Not the Same Thing
Sharing an address is often confused with a holding company structure, but they answer different questions. A holding company is about ownership, where one parent LLC owns other LLCs. Sharing an address is about location, where separate LLCs that may have nothing to do with each other simply receive mail at the same place.
- Holding company: a parent entity owns subsidiary LLCs, and the structure is about how the businesses relate to each other.
- Shared address: independent LLCs use one address for mail and filings, with no ownership link required.
- You can have either, both, or neither. Two unrelated LLCs can share an address, and a holding company's subsidiaries can each use different addresses.
If your question is really about ownership and structure rather than a shared mailing location, see the holding company LLC and business address. And if you have not split the businesses into separate LLCs yet and are weighing whether to, that decision comes first: see multiple businesses under one LLC.
Register Each Business as a Separate Recipient
When several businesses use one professional address, the practical work is keeping their mail apart. At a virtual office or mailbox, you register each one as its own recipient at the address, so mail addressed to each name is sorted and handled under that name rather than piling into one stream.
- Each business is added as a named recipient, so a bank statement for one is not mixed with another.
- Some providers assign a suite or unit number, which keeps the address consistent while still distinguishing the entities. At a CMRA address the USPS rule is narrower: the customer designator has to be written as PMB or #, and it cannot be merged into the building's own suite number.
- Mail scanning then routes each one's documents to the right place, which matters once you are tracking filings for several businesses.
Name each business precisely
Use each business's exact legal or registered name when you add it as a recipient. Mismatched or informal names are a common reason mail gets misrouted or a bank flags an account, especially when several similar businesses share one address.
Keep the Entities Genuinely Separate
Sharing the address is allowed, and it is also one of the things a court can weigh if someone later argues your LLCs were never really separate companies. The protection an LLC offers depends on treating each company as a distinct business, in its money, its records, and its paperwork.
- Separate bank accounts: each LLC needs its own account, and money should not move casually between them without documentation.
- Separate records: keep books, contracts, and filings for each entity on their own rather than in one combined set.
- Separate contracts: sign agreements in the correct entity's name so obligations land with the right company.
A shared address is a factor, not a non-factor
Associated Vendors, Inc. v. Oakland Meat Co., 210 Cal. App. 2d 825 (1962), is the California decision that courts continue to cite for the alter ego factor list, and "the use of the same office or business location" is on it, directly beside the employment of the same employees and the same attorney, on the same list as commingling of funds. The same opinion notes that in all the cases it surveyed, several of those factors were present together, and that the factors were not conclusive on the trier of fact, which is why a shared address by itself does not set aside liability protection. It is not a free pass either. It counts, in combination. California applies this common law alter ego analysis to LLC members under Corporations Code 17703.04(b). Factor lists vary by state. This is general information, not legal advice.
What Stays Per Entity, Every Time
Here is the part the one-line answer skips. Sharing an address consolidates the address. It consolidates nothing else, and the work behind each entity does not get cheaper because the mail lands in the same building.
- The EIN is per entity, and there is a rate limit on getting them. The IRS instructions for Form SS-4 (Rev. 12/2025) state that EIN issuances are limited to one per responsible party, per day, across online, phone, fax, and mail. Five LLCs under one responsible party is a five-day floor, not an afternoon.
- Mail authorization is per entity at a CMRA address. USPS rules require the agency to have a current PS Form 1583 on file for every addressee, and mail for an addressee with no form on file gets returned to the Post Office as undeliverable. The form has one business or organization name field, so a second entity means a second form, not an extra line.
- State fees are per entity. California charges every LLC registered or doing business in the state an $800 annual tax, due, in the FTB's words, "even if you are not conducting business," until you cancel the LLC. The first-year exemption applied only to tax years beginning on or after January 1, 2021 and before January 1, 2024, so it has lapsed, and the first-year relief still on the FTB's page is short form cancellation within a year of organizing. Five California LLCs at one address is $4,000 a year before anything happens.
- The registered agent is per entity and per state, covered below.
None of this makes a shared address wrong. It just means the address was never the expensive part, so consolidating it does not save what people expect it to save.
The Two Costs the Short Answer Leaves Out
Search this question and the results answer yes, as long as each company is a separate entity. That is the premise, not the answer. There are two places a shared address shows up in the rules that govern the entities themselves, and neither one is a rule that stops you. A third place, Google Business Profiles, comes further down and works differently.
The first is the alter ego factor list covered above: it is one of the things a court can weigh, and it never decides anything by itself.
The second is in the bank's regulator rather than the bank. We read the published address rules at two business banks that put them in writing. Mercury names PO boxes, virtual addresses, commercial mail receiving agencies, mail centers, and registered agent addresses. Relay names PO boxes, virtual mailboxes, mailbox rental services, and registered agent addresses. Both rule on what kind of address you use. Neither one, on the pages we read, says anything about how many businesses share one. That is two banks and their public help pages, not every bank and not anyone's internal underwriting, which we cannot see. What we can see is the examiner's side, and there the pattern is named outright.
The examiner's manual names it, the bank's policy does not
The FFIEC BSA/AML Examination Manual, the manual federal examiners grade banks against, lists under Shell Company Activity: "Transacting businesses share the same address, provide only a registered agent's address, or have other address inconsistencies." It sits in a funds-transfer and shell-company monitoring context rather than in an account-opening rule, so the manual is an instruction to examiners rather than a signup test. What a given bank does with it at onboarding is on the side we cannot see. What it does tell you is that the pattern is visible, and that the separation work matters more than the location does.
Two Google Business Profiles at One Address
A large share of the search results for this question are forum threads asking about Google listings rather than state filings. Google does publish a rule for it. It is just not on the page most answers cite: the main guidelines page does not use the phrase "same address" anywhere. The rule lives on the duplicate-profiles page instead.
Google's test is that multiple businesses at one address can each have a profile if they are "distinct businesses with different names and clearly visible differences in signage" and each one is independently eligible for a profile. Note what is not in that test: category. The common advice that two listings work as long as you pick different categories is not the published standard. Names and signage are.
Eligibility comes before the same-address test, and this is where a mail address stops
Google's guidelines say that if a business rents a physical mailing address but does not operate out of that location, that location is not eligible for a Business Profile at all, and that any business showing an address on Google should maintain permanent fixed signage of its name at that address. So for a mail or virtual office address the same-address question never really arrives. It fails the eligibility gate first. save office gives you an address for filings, banking, and mail. It is not a staffed, signed storefront, and it is not a route to a Business Profile.
If both businesses genuinely operate at the location and Google still flags the profiles as duplicates, the appeal is evidentiary rather than technical: Google asks for evidence of permanent signage that clearly shows both businesses. That is the same standard as the original test, applied with photos.
Registered Agents Across Multiple States
A shared business address is one layer. The registered agent is another, and it applies to registered entities rather than to an unregistered sole proprietor. For entities it is per entity and per state: every LLC needs a registered agent in each state where it is registered, which is where running several LLCs in different states gets more involved.
- Each LLC needs a registered agent with a physical address in its state of registration.
- One provider can often serve as registered agent for several of your LLCs, which consolidates the legal mail layer.
- If an LLC operates in more than one state, it usually needs registered agent coverage in each of those states.
For how the registered agent address differs from the business address you share across entities, see registered agent address vs business address, and for the three address roles every single LLC has, the three business addresses every LLC needs.
When Your Businesses Are in Different Cities
Many serial founders end up with businesses in more than one state. Once they are spread across cities, a single provider that operates in several of them lets you give related businesses a consistent, professional address rather than juggling a different mailbox vendor in each market.
- One dashboard can hold mail for several businesses across different cities, instead of a separate login per location.
- Adding a new business or a new city is faster when your addresses are not tied to individual leases.
- Before you put any address on a filing, you can confirm how it is classified so a registration is not rejected.
Run any address through our free Address Checker before you file, and set up addresses for your businesses through save office onboarding. save office operates in several US cities, so a portfolio of businesses can share one consistent business address across markets.
As many LLCs as you register can share one address, two businesses included, and the honest version of that answer is that the address is the only thing that gets shared. Where the question lands depends on what you are running: the Secretary of State for an LLC, usually a county clerk for a DBA, nowhere at the state level for an unregistered sole proprietor. If they are separate entities, each still needs its own EIN, its own mail authorization, its own state fees, and its own registered agent designation. Register each one wherever its type requires it, add each as a named recipient so the mail stays sorted, keep separate bank accounts and records, and the shared address stays what it should be: a location, not an argument that your companies were never separate. The one place it is not just a location is Google, where a mailing address you do not operate from is ruled out on eligibility before the same-address question is even reached.
If the businesses actually own one another rather than just sharing a location, that is a different structure, so read the holding company LLC and business address before you decide how to organize them.
