Key Takeaways
- Service of process is the core duty. Under Federal Rule of Civil Procedure 4(h), a company can be served by delivering the summons and complaint to an agent authorized by appointment or by law.
- The address has to be a real street address with someone there. Washington and Ohio both reject PO boxes and private mailbox services.
- A registered agent handles official mail, not everyday business mail. Customer letters, vendor invoices, and packages belong at a separate business address.
- Your registered agent address is public record and separate from your business address. The two can match only if the location meets the agent requirements.
See what a registered agent does: the four duties set by state law, how service of process arrives, and which mail they handle.
When you form an LLC or corporation, appointing a registered agent is one of the key legal requirements. But what does a registered agent actually do, and why does your business need one?
A registered agent receives legal documents, government notices, and other official correspondence on your company's behalf. Missing these documents can lead to legal complications, missed deadlines, and potential penalties.
This guide explains what a registered agent does, which documents they handle, what happens if important notices are missed, and whether hiring a professional registered agent service is the right choice for your business.
What Does a Registered Agent Do?
A registered agent has four duties. Each one is written into state law rather than left to the agent to define.
1. Accept Service of Process
When someone sues your business, a process server or sheriff hand-delivers the summons and complaint to your registered agent. Washington's statute, RCW 23.95.105(35), describes the agent as authorized to receive service of any process, notice, or demand that law allows to be served on the entity.
2. Receive Official State and Tax Mail
State agencies send annual report reminders, franchise tax notices, delinquency notices, and compliance correspondence to the agent on file.
3. Stay Available at the Listed Address
Ohio defines a qualifying agent address as a place customarily open during normal business hours with an authorized person present. Delaware and Virginia use the same standard.
4. Forward What Arrives
Receiving the documents is only half the job. The agent has to get them to you quickly enough that you can respond inside the deadline the papers start.
What Is Service of Process, and How Does It Reach Your Agent?
Service of process is the formal delivery of court papers that brings your company into a lawsuit. The documents are usually a summons and a complaint. Delivery is what starts your response deadline, so the date it happens matters more than the date you read it.
Rule 4(h)(1)(B) of the Federal Rules of Civil Procedure allows a corporation, partnership, or association to be served by handing the summons and complaint to an agent authorized by appointment or by law. State courts have parallel rules. This is why the role exists in the first place: courts need one reliable place to deliver papers for every registered business.
In-person delivery is also why mailbox addresses are not accepted. Washington excludes PO boxes, private mailboxes, and virtual addresses from the registered agent field. Ohio excludes PO boxes and commercial mail receiving agencies. If you want the detail on which address types work where, see our guide on using a PO box for an LLC address.
What Happens if Service of Process is Missed?
The case moves ahead whether or not the papers reached you. That is worth understanding plainly, because the sequence is written into the rules.
If your agent cannot be found at the listed address, the state provides a backup route. Colorado allows the entity to be served by registered or certified mail at its principal address under section 7-90-704(2), C.R.S. Ohio lets a party file an affidavit and serve the Secretary of State as the company's agent instead. California permits court-ordered substituted service on the Secretary of State once direct attempts have been shown to be reasonably diligent.
Once service is complete by any of those routes, Rule 55(a) directs the clerk to enter a default when a party fails to plead or otherwise defend. New York's Department of State makes the same point in its own filing instructions for business corporations: keeping the service of process address current is how a company avoids a default judgment.
The fix is straightforward. Keep a working agent on file, and update the record the same week anything changes. Our walkthrough on how to change a registered agent covers the filing itself.
What Mail Does a Registered Agent Handle?
Registered agent service covers official documents. Here is what typically arrives and who sends it.
Document | Who Sends It | Handled by Your Registered Agent |
Summons and complaint | Process server, sheriff, or plaintiff's attorney | Yes |
Subpoenas | Courts and attorneys | Yes |
Wage garnishment and charging orders | Courts | Yes |
Annual or biennial report reminders | Secretary of State | Yes |
Franchise and state tax notices | State revenue agency | Yes |
Delinquency and compliance notices | Secretary of State | Yes |
Customer and vendor mail | Businesses and individuals | No |
Packages and deliveries | Carriers | No |
Marketing mail | Mailing lists | No |
Important: A registered agent service is not a replacement for your regular business mailing address. Customer correspondence, vendor invoices, packages, and other routine deliveries generally require a separate mailing address.
Document forwarding times also vary by provider. With Swyft Filings' registered agent service, service-of-process documents are typically uploaded to your account within two to three hours, while other scanned notices may take longer depending on volume.
What a Registered Agent Does Not Do
Although a registered agent receives important legal and government correspondence, the role has clear limits.
A registered agent does not automatically have ownership or management authority over your business.
Their responsibilities generally do not include:
- Signing contracts on behalf of your company
- Making business or financial decisions
- Managing business accounts
- Providing legal representation
- Responding to lawsuits on your behalf
- Handling routine customer mail or packages
The distinction is simple: Your registered agent receives and forwards official documents. You and your authorized representatives remain responsible for reviewing those documents and deciding what action to take.
Is Your Registered Agent Address the Same as Your Business Address?
Is Your Registered Agent Address the Same as Your Business Address?
Not necessarily. Your registered agent address and business address serve different purposes, although they can sometimes be the same location.
A registered agent address identifies where legal documents and official notices can be delivered. It generally must be a qualifying physical street address within the state and is included in public business records.
Your principal business address identifies where your company operates or maintains its main office. The requirements for this address may differ depending on the state and business structure.
You can use the same address for both purposes if it meets the applicable registered agent requirements and an eligible agent agrees to serve there.
For example, if you operate your LLC from home and appoint yourself as the registered agent, your home address may become publicly available through state business records.
A professional registered agent service can provide a qualifying registered office address, helping business owners avoid listing their home address as the registered agent address.

What Is a Registered Agent Called in Your State?
The job is the same across the country. The label on the form is not.
Term | Used in | What the Term Emphasizes |
Registered agent | Most states | The name and address are registered with the state |
Statutory agent | Ohio, Arizona | A statute creates the requirement |
Resident agent | Maryland, and others | The agent has to be a state resident |
Agent for service of process | California | The central duty is accepting court papers |
Registered office | Pennsylvania | The requirement attaches to the address |
New York works differently. Under the state's own LLC formation instructions, the company designates the Secretary of State as its agent for service of process and supplies an address for the state to mail process to. A separate registered agent can be named as well, and many companies do name one so that papers reach them directly.
Because the terminology shifts, it is worth reading your own state's page before you file. Our state guides for California, Ohio, and Washington each cover the local rules.
What Does a Registered Agent Cost?
Naming an agent when you form your company is usually free. Ohio charges no fee for the original appointment of a statutory agent.
Costs appear later. Changing your agent carries a state filing fee that varies, and letting the requirement lapse can cost more. Ohio charges $25 to reinstate an entity and appoint an agent after a failure to maintain one, and the Secretary of State notes that skipping an agent update can lead to entity cancellation.
A professional service is the other line item. Swyft Filings' registered agent service runs around $149 per quarter and covers the address, same-business-day document upload for service of process, and a dashboard holding everything received. There are practical reasons to hire a dedicated registered agent beyond the address itself, including keeping your home address off the public record.
Conclusion
A registered agent does one job well defined by statute: accept service of process and official state mail at a staffed in-state address, then get it to you in time to act. The duties are narrow, but the deadline that attaches to them is real, which is why states treat a current agent record as a condition of good standing.
Two things keep this simple. Make sure the address on file is one where someone reliably accepts documents during business hours, and update the record promptly whenever your agent or their address changes.
If you would rather not carry that on your own calendar, Swyft Filings can serve as your registered agent in any state, or handle a change of registered agent from your current provider. You can also see how the role fits into the wider process of forming an LLC.
FAQs
In most states, yes, as long as you are 18 or older, have a physical street address in the state, and can be there during business hours. Your company itself usually cannot serve as its own agent, though you as an individual can. The tradeoff is privacy and scheduling. Your address goes on the public record, and someone has to be present at it on any given business day to accept hand-delivered papers.
You appoint a replacement and file the change with your Secretary of State. Ohio uses Form 521 for statutory agent updates, and most states have an equivalent statement of change. Do not leave a gap. States require a company to maintain an agent continuously, and an outdated record is what triggers the substitute service routes described above.
A professional service records what arrives, scans it, and forwards it to you. The agent does not advise you on the contents, respond on your behalf, or make decisions about the matter. Reviewing the documents and deciding how to respond stays with you and your attorney.
Registered agent service is for official notices and service of process, not general deliveries. Packages and routine correspondence need a business mailing address instead.
Yes. The requirement attaches to the entity, not its size. Washington's statute applies it to every domestic entity and every registered foreign entity, and other states follow the same approach.
Yes. If you register to do business in another state, that state requires an agent with a qualifying address inside its borders. A company operating in four states maintains four agents, which is one reason multi-state owners tend to consolidate with a single provider.
A registered agent can be a business owner, employee, business partner, family member, attorney, or a professional registered agent service. You can also serve as your own agent in most states if you meet the legal requirements. Generally, registered agents must have a physical address in the state, be available during regular business hours, and agree to receive legal documents. Some states have additional eligibility and residency requirements.
