Registered agent vs virtual mailbox: what each address is for

Updated October 27, 2026 · State statutes, Secretary of State pages, USPS DMM 508.1.8, IRS SS-4 instructions, and provider pricing pages checked on that date unless a row shows its own date · Affiliate disclosure

A registered agent and a virtual mailbox both give your business an address that isn't your home, so people mix them up. They do different jobs under different rules. A registered agent is the person or company that state law says must be available at a physical in-state address to accept lawsuits and official notices for your entity. A virtual mailbox is a USPS-registered mail-receiving business (a CMRA) that receives, scans, and forwards your everyday mail. Most LLCs end up with both. This page shows which address goes in which field, quoting the statutes and the institutions' own pages.

Short answer (checked October 27, 2026)

⚖️ Registered agent: required by state law for LLCs and corporations. It needs a physical street address in the state where someone can accept service of process. Delaware and Texas say in so many words that a mail-forwarding or mailbox service alone doesn't count.

📬 Virtual mailbox: optional. It's built for your mailing address: IRS letters, vendor invoices, bank statements. It can't be your registered agent address.

🔁 The overlap: some mailbox companies also sell a registered agent service, but it's a separate address and a separate fee. A registered agent address is also not a substitute for an operating address at banks and Stripe's money-management products.

Registered agent vs virtual mailbox, side by side

How the two address types differ. Each row is based on the statutes and USPS rules listed under Sources, checked October 27, 2026.
	Registered agent	Virtual mailbox (CMRA)
What it's for	Accepting service of process and official notices for your entity, then forwarding them to you (for example 6 Del. C. § 18-104(e), Fla. Stat. § 605.0113(3))	Receiving all your ordinary mail "as a business service" and holding, scanning, or remailing it (USPS DMM 508.1.8)
Required?	Yes, for LLCs in every state we checked (DE, WY, FL, TX, WA, CO)	No. It's a convenience and privacy choice
Who regulates it	The state of formation (and each state where you register to do business)	The U.S. Postal Service
Address rules	A physical street address in that state, where the agent can be served in person	The CMRA's street address plus your box, written as "PMB 234" or "#234"
Paperwork	The agent is named in your formation filing, and in Florida and Texas the agent must accept or consent to the appointment	USPS PS Form 1583 with two IDs, signed in front of the CMRA or a notary
Where it shows up	State filings (the registered office/agent fields)	Mailing-address fields: IRS, vendors, customers, and banks where they allow it
Can one replace the other?	No. A registered agent isn't set up to handle all your mail, and the agent's terms decide what it forwards	No. DE and TX bar a mail-only service from acting as the registered office or agent, and WA and CO bar PMB or commercial addresses there

For the USPS side in detail (the PMB format, USPS Form 1583 ID rules, and what happens when you close a box), see What is a CMRA address?

Which address fields each one fits

An LLC gets asked for several different addresses. Here's where each address type belongs. The virtual mailbox for LLC guide goes field by field with every institution we've sourced.

Registered agent / registered office

Registered agent address only. This is a state-law field. A virtual mailbox doesn't qualify (see the state table below).

Principal office (state filings)

Depends on the state form. Florida's instructions ask for "the street address of the LLC's principal office." Check your Secretary of State's instructions before using either address type here.

Mailing address

Virtual mailbox is the natural fit. Florida's instructions say the LLC's mailing address can even be a P.O. box. The IRS SS-4 line 4 mailing address has no stated type restriction.

Bank / Stripe operating address

Neither, usually. Relay, Mercury and Stripe's money-management products list registered agent addresses, and CMRA or virtual mailbox addresses, as not accepted for the operating or physical address.

What state law says (sourced table)

We quote the statute or the Secretary of State's own instructions for each state. Wording varies, but the test is the same everywhere we checked: a real place in the state where the agent can be handed papers.

Registered agent address rules in six states, from primary sources checked October 27, 2026.
State	Who can be the agent	Address rule (quoted)	Mailbox named?	Source
Delaware	The LLC itself, a Delaware resident, or a domestic or authorized foreign entity. Agents for more than 50 entities must meet commercial-agent rules.	The agent must keep an office "generally open" (or, for an individual, be "generally present") to accept service of process, and "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."	Yes: virtual office and mail forwarding service	6 Del. C. § 18-104
Wyoming	A resident individual 18+, or an entity with a written agency agreement with an individual. Agents for more than 10 entities must register as commercial registered agents.	The registered office must be "a street address in Wyoming which shall be a physical location where the business entity's registered agent… can accept service of process… and is physically present at that location."	Not by name. Requires physical presence	W.S. 17-28-101
Florida	A Florida resident, or an authorized entity, with a business address identical to the registered office. The LLC can't be its own agent, but a member or manager can.	"The registered agent must have a physical street address in Florida. (Do not list a P.O. Box address.)"	Not by name. P.O. boxes excluded	Sunbiz instructions; Fla. Stat. § 605.0113
Texas	A Texas resident, or an organization other than the entity itself, that has consented to serve. An organization must have an employee at the office during normal business hours.	The registered office "must be located at a street address where process may be personally served" and "may not be solely a mailbox service or a telephone answering service."	Yes: mailbox service	Tex. Bus. Orgs. Code § 5.201; SOS Form 401 instructions
Washington	An agent with a physical Washington address. If your business has none, the SOS says you can hire a Commercial Registered Agent listed in its filing system.	"The Registered Agent must maintain a physical address in Washington State (PO Boxes or PMBs are prohibited)."	Yes: PMBs (private mailboxes)	WA Secretary of State
Colorado	An individual 18+ who lives or has a usual place of business in Colorado and holds a valid Colorado driver's license or ID (or verifies residency), or an entity in good standing with a usual place of business in Colorado	"Commercial or P.O. Box addresses cannot be used as a registered agent's physical street address." They're allowed only as the agent's separate mailing address.	Yes: commercial addresses	Colorado SOS FAQ

These six states are a sample, not all 50. For a quick state-by-state view, open the interactive LLC & virtual mailbox map. If your state isn't listed, read its Secretary of State's registered agent page before you file.

How banks, Stripe and the IRS treat each address

Outside state filings, the question flips: will an institution accept a registered agent address, or a virtual mailbox address, in the field it's asking about? Every row quotes and links the institution's own page or the statute.

Institution	Address field	Verdict	What the source says	Source (checked)
Stripe — Issuing, Treasury for platforms, Opal, Corporate Card Payments / fintech	Business address and account representative address	Rejects CMRA / virtual mailbox	Stripe's docs say these products enforce validations that the address is not a PO box, private mailbox, Commercial Mail Receiving Agency (CMRA) or registered agent address. New businesses are blocked from onboarding until they provide a valid physical address; existing accounts get a 30-day grace period before capabilities are disabled. “Stripe can no longer allow addresses for registered agents, mailbox services, or virtual address services.”	Stripe Docs: Address validation (Issuing) October 27, 2026
Stripe — Connect Accounts API (v1/v2) error codes Payments / fintech	Account address	Rejects CMRA / virtual mailbox	A Stripe changelog entry dated 2026-09-30 adds the error code invalid_address_cmra_address, returned when an account's address is identified as a CMRA or virtual mailbox address; the account holder must update the address. A separate code covers registered agent addresses (resolvable with proof of address). The entry does not list which capabilities trigger the check, so treat it as 'may be rejected' for ordinary card payments. “Returned when an account's address is identified as a Commercial Mail Receiving Agency (CMRA) or virtual mailbox address.”	Stripe changelog: address validation errors for CMRAs and registered agents October 27, 2026
Stripe Atlas — Delaware incorporation & EIN application Incorporation / fintech	Company address on Atlas application (vs. founder home address & registered agent)	Accepted in some fields only	Stripe Atlas explicitly allows a virtual address as your company address during incorporation (used on IRS Form SS-4 and formation filings, and where the IRS mails the physical EIN confirmation letter). However, each founder must still provide a residential home address for identity verification and 83(b) elections, and Atlas’s Delaware registered agent address cannot be used as a general company or mail-forwarding address. “If you don’t have an official company address yet, you can use your home address or get a virtual address through one of our partners. We include this address in your EIN application to the IRS and in incorporation documents.”	Stripe Docs: How to incorporate your company (Stripe Atlas) October 26, 2026
Mercury Bank / fintech	Legal address, physical (day-to-day) address, beneficial owner home address (mailing/card address is separate)	Accepted in some fields only	Mercury's Company address requirements article says the physical address (where you and your team work day-to-day) cannot be a P.O. box, virtual address, commercial mail receiving agency, mail center or registered agent address. Its legal-address article says P.O. boxes and virtual offices/workspaces are not accepted as the legal address, and its eligibility article says registered agent addresses, P.O. boxes and UPS Store addresses are not accepted for the principal place of business. Each beneficial owner's home address cannot be a PO box, mail drop, or commercial mail-receiving or virtual address service. The mailing address (where physical cards are sent) must be a physical, USPS-deliverable address; Mercury's help pages do not name CMRAs for that field. “We don't accept a P.O. box, virtual address, commercial mail receiving agency, mail center, or registered agent address.”	Mercury Help: Company address requirements Mercury Help: Updating your company's legal address Mercury Help: Eligibility and requirements Mercury Help: Fixing undeliverable addresses October 26, 2026
Relay Bank / fintech	Legal address (registered agent OK) vs. operating address and owner personal address (registered agent, PO box, virtual mailbox not OK)	Accepted in some fields only	Relay's help article (updated August 11, 2026) says a registered agent address may serve as the business's legal address, including for non-U.S. residents, but it cannot be the operating address or an owner's personal residential address. Registered agent addresses, PO boxes, and virtual mailboxes or mailbox rental services are listed as not acceptable operating addresses. “Yes, a registered agent address may serve as your business's legal address on Relay, including for non-U.S. residents establishing a U.S. business. It cannot be used as your operating address or your personal residential address.”	Relay Help: Using a Registered Agent Address and Operating Address Relay Help: Required Documents to Open a Relay Account by Entity Type Relay Help: Updating your business and billing address on Relay October 27, 2026
IRS — Form SS-4 (EIN application) Government agency	Line 4 mailing address / Line 5 street address	No restriction stated	The SS-4 instructions describe line 4 as the mailing address for the entity's correspondence (generally used on all tax returns) with no stated restriction on type. Line 5 is the physical street address, needed only if different from the mailing address, and must not be a P.O. box. The instructions do not mention CMRAs. “Provide the entity's physical address only if different from its mailing address shown on lines 4a–4b. Don't enter a P.O. box number here.”	IRS: Instructions for Form SS-4 October 27, 2026
Delaware — LLC registered agent (6 Del. C. § 18-104) State law	Registered office / registered agent	Rejects CMRA / virtual mailbox	Every Delaware LLC must keep a registered office and agent in Delaware. The agent must keep an office that is generally open (or be generally present) to accept service of process, and may not perform its duties solely through a virtual office or a mail forwarding service. Filed addresses must include street, number, city and postal code. “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.”	Delaware Code Title 6, Chapter 18, Subchapter I (§ 18-104) October 27, 2026
Washington Secretary of State — registered agent State agency	Registered agent address	Rejects CMRA / virtual mailbox	The registered agent must keep a physical address in Washington; PO boxes and PMBs (private mailboxes) are prohibited. A PO box can be added only as a separate mailing address. Without a WA physical address you can hire a Commercial Registered Agent. “The Registered Agent must maintain a physical address in Washington State (PO Boxes or PMBs are prohibited).”	WA Secretary of State: Registered Agents October 27, 2026
Colorado Secretary of State — registered agent State agency	Registered agent street address (separate mailing address allowed)	Accepted in some fields only	The registered agent needs a physical Colorado street address that is customarily open during normal business hours. Commercial or P.O. box addresses cannot be used as that street address, but they can be entered as the agent's mailing address if located in Colorado. “Commercial or P.O. Box addresses cannot be used as a registered agent's physical street address.”	Colorado SOS: Registered agent FAQs October 27, 2026
Wyoming — registered office & agent (W.S. 17-28-101) State law	Registered office / registered agent	Physical address required (CMRA not named)	Every business entity must keep a Wyoming registered office at a street address that is a physical location where the registered agent (or a natural person with an agency relationship with the agent) can accept service of process and is physically present. The agent's business office must be identical with the registered office, and agents serving more than ten entities must register as commercial registered agents. The statute does not name CMRAs, but a mail-only box can't meet the 'physically present' test. “A registered office that may be the same as any of its places of business but shall be located at a street address in Wyoming which shall be a physical location where the business entity's registered agent, or a natural person who has an agency relationship with the registered agent, can accept service of process as provided in W.S. 17-28-104 and is physically present at that location”	Wyoming Statutes Title 17, Chapter 28 (W.S. 17-28-101) October 27, 2026
Florida — LLC registered agent (s. 605.0113, F.S.; Sunbiz instructions) State agency	Registered agent / registered office (mailing address is a separate field)	Physical address required (CMRA not named)	Florida law requires each LLC to keep a registered office and a registered agent whose business address is identical to the registered office. The Division of Corporations' filing instructions say the agent must have a physical Florida street address and not a P.O. box. The same instructions say the LLC's separate mailing address may be a P.O. box. CMRAs are not named. “The registered agent must have a physical street address in Florida. (Do not list a P.O. Box address.)”	Florida Division of Corporations: Instructions for Articles of Organization (FL LLC) Florida Statutes s. 605.0113, Registered agent October 27, 2026
Texas — registered agent & office (BOC § 5.201) State law	Registered office / registered agent	Rejects CMRA / virtual mailbox	Texas entities must keep a registered agent and a registered office in Texas. The registered office must be a street address where process may be personally served on the agent and may not be solely a mailbox service or telephone answering service. An organization acting as agent must have an employee there during normal business hours. The Secretary of State's Form 401 instructions repeat the rule. “The registered office: (1) must be located at a street address where process may be personally served on the entity's registered agent; (2) is not required to be a place of business of the filing entity or foreign filing entity; and (3) may not be solely a mailbox service or a telephone answering service.”	Texas Business Organizations Code, Chapter 5 (§ 5.201) Texas SOS: Form 401 instructions (registered agent/office) October 27, 2026

Not listed means we haven't found a primary source yet, not that the institution accepts either address. The full list is in the acceptance database, and bank-by-bank detail is in the bank account guide and Stripe guide.

Key takeaway: a registered agent address is a legal-notice address. Relay accepts it as your legal address but not as your operating address. Bluevine rejects registered agent addresses outright, and Mercury doesn't accept it as your physical address. Stripe's Issuing, Treasury for platforms, Opal and Corporate Card products reject registered agent, mailbox, and virtual addresses for both the business and the account representative. Your operating address is still where you actually work.

Providers that sell both, compared

A few virtual mailbox companies also sell registered agent service as an add-on. Read the "Registered agent add-on" column: it's a separate address and a separate fee, not a second use of your mailbox address. Stable's pricing FAQ says its registered agent addresses "are separate addresses and services from your primary Stable address." Prices come from each provider's own pricing page on the date shown.

Entry plans as published on each provider's pricing page. Prices exclude tax. “Varies” means the price depends on the address/location you pick.

What we verified on October 27, 2026:

iPostal1: registered agent service is an "add-on available in your Digital Mailbox for $99/year with any business plan." It's listed in AK, AL, AZ, CA, CO, DC, DE, FL, GA, IL, MA, MN, MO, MS, NC, NJ, NM, NV, NY, SC, TX, UT, VA, WA and WY. Business plans start at $14.99/month, and the price varies by location.
Stable: registered agent add-on at $25/month per state, in any U.S. state, D.C. or Puerto Rico. Stable says "a Stable plan is required to purchase a registered agent." Plans start at $59/month ($49/month billed yearly).
LegalZoom (Earth Class Mail / LZ Virtual Mail): LegalZoom sells Registered Agent Services as a separate product at $249/year. It auto-renews, and LegalZoom says that purchase price is "only available for first time registered agent customers." Its virtual mail pricing page doesn't list a bundle.
Traveling Mailbox, Anytime Mailbox, PostScan Mail: we found no registered agent price on the pricing pages we checked. PostScan Mail links to a registered agent page, but we didn't find a price there, so the table shows "not stated."

How to choose

Start with the registered agent, because it isn't optional. If you have a physical address in the state where you form, and someone is there during business hours, you may be able to serve yourself (check who's eligible in the table above). If not, hire a commercial registered agent in that state.
Add a virtual mailbox if you want your everyday mail handled remotely, or kept off your home address. It goes in mailing-address fields, not the registered agent field.
Compare the total cost. A bundled add-on (iPostal1 $99/year, Stable $25/month per state) is convenient. It's still two services, so compare it with a standalone agent in your state.
Check where the agent forwards mail. State law says the agent forwards process and notices to the company (Delaware and Florida spell this out). Ask how quickly they scan or forward, and to which address.
Keep a real operating address for banks and Stripe. Neither a registered agent address nor a virtual mailbox address works as an operating address at the institutions in the table above.
Think about more states. Each state you register in needs its own registered agent. That's why some add-ons are priced per state.

Checklist

Pick your state of formation and read its registered agent rule (Secretary of State page or statute).
Choose a registered agent with a physical in-state street address: yourself if eligible, or a commercial agent. Get their consent where the state requires it (Florida and Texas do).
Optional: open a virtual mailbox and complete USPS PS Form 1583 with a primary and a secondary ID.
On your formation filing, put the agent's address in the registered agent/office field, and the mailbox (if the form allows) in the mailing-address field.
On IRS Form SS-4, use your chosen mailing address on line 4. Line 5 is only for a different physical street address, and it can't be a P.O. box.
At the bank and Stripe, give your real operating address and owner home address. Add the mailbox as a mailing address only where allowed.
Write down the agent's and mailbox's renewal dates. If either lapses, you'll need to file a change with the state or update your mailing address everywhere (IRS Form 8822-B for the IRS).

Frequently asked questions

What is the difference between a registered agent and a virtual mailbox?

A registered agent is the person or company that state law requires your LLC or corporation to keep at a physical in-state address to accept service of process and official notices, then forward them to you. A virtual mailbox is a Commercial Mail Receiving Agency (CMRA) under USPS rules that receives, scans and forwards your everyday mail. The first is a legal requirement, the second is an optional mailing address.

Can I use a virtual mailbox as my registered agent address?

No, not in any state we checked. Delaware (6 Del. C. § 18-104) says an agent may not perform its duties solely through a virtual office or a mail forwarding service, and Texas (BOC § 5.201) says the registered office may not be solely a mailbox service. Washington prohibits PO boxes and PMBs, Colorado bars commercial or P.O. box addresses as the agent's street address, and Florida and Wyoming require a physical street address where the agent can be served.

Can I use my registered agent's address as my business mailing address?

Only if your agent's terms allow it, and many institutions limit it. Relay accepts a registered agent address as your legal address but not as your operating or personal address. Mercury doesn't accept it as your physical address, and Stripe's Issuing, Treasury for platforms, Opal and Corporate Card products reject registered agent addresses. A virtual mailbox is the address built for everyday mail.

Do I need both a registered agent and a virtual mailbox?

You need a registered agent in your state of formation and in each state where you register to do business. A virtual mailbox is optional. It's useful if you want mail scanned and forwarded, or want to keep your home address off your mailing-address fields.

Can a virtual mailbox company also be my registered agent?

Some sell it as a separate service. As of October 27, 2026, iPostal1 listed a $99/year registered agent add-on with any business plan in 25 listed jurisdictions, and Stable listed $25/month per state (a Stable plan is required). LegalZoom sells Registered Agent Services separately at $249/year for first-time customers. The registered agent address is a separate address from your mailbox.

Can I be my own registered agent?

It depends on the state. Delaware lets the LLC itself or a Delaware resident serve. Florida says the LLC can't be its own agent, but a member or manager can. Texas allows a resident individual who consents, or an organization other than the entity. Wyoming allows a resident individual 18 or older. In each case you need a qualifying in-state street address and must be available there to accept service.

Which address goes on IRS Form SS-4?

The SS-4 instructions call line 4 the mailing address for the entity's correspondence, generally used on all tax returns, with no stated type restriction, so many owners use a virtual mailbox there. Line 5 is the physical street address only if different, and the IRS says not to enter a P.O. box. The instructions don't mention registered agent addresses. Report later mailing-address changes on Form 8822-B.
