Statutory Agent, Registered Agent, Resident Agent: What Is the Difference?

Statutory agent, registered agent, and resident agent are the same role under different names. Each one is the party your business names to receive service of process, meaning lawsuits, subpoenas, and official notices, plus mail from the state. Which word you use is decided entirely by the state where you form or register, not by any difference in duties.

The core job is the same wherever you file: a named party at a real in-state address who accepts service of process. The legal standard around it is not identical. Most states require a physical street address (no PO box) and availability during normal business hours. Some, such as Arizona, require an agent who can reliably receive and forward process rather than one physically present all day. Pennsylvania requires a registered office address instead of a named agent. New York and West Virginia name the Secretary of State as your agent automatically and treat a private appointment as optional. So when a form asks for a statutory agent and a competitor tells you to hire a registered agent, they are usually describing one job — but check your state’s page before you assume it. For the full duties and rules, see our registered agent overview.

Two states use statutory agent. Arizona says it in the statute itself — A.R.S. § 29-3115 is headed “Statutory agent”. Ohio says it on every form: the LLC statute, ORC 1706.09, calls it an “agent for service of process”, but the Secretary of State’s forms are titled Statutory Agent Update (Form 521) and the Articles of Organization (Form 610) ask for a statutory agent — so statutory agent is the word you will actually type.

Note that the document you type it on is not the same everywhere either. Arizona and Ohio LLCs file Articles of Organization, but Delaware, Texas, Alabama, New Jersey, Washington, Mississippi, New Hampshire, Maine and Puerto Rico file a Certificate of Formation, and Pennsylvania, Massachusetts, Iowa, Utah, Idaho, Connecticut, Arkansas and Nebraska file a Certificate of Organization. An Arizona statutory agent does the same work a registered agent does in Texas; only the paperwork’s vocabulary moves.

Several jurisdictions use resident agent: Kansas, Maryland, Michigan, Rhode Island and Puerto Rico, plus Massachusetts for LLCs. Their statutes and filing forms use resident agent to describe the same position most states call a registered agent.

Two details are worth knowing. Massachusetts splits by entity type — M.G.L. c. 156C § 5 requires an LLC to maintain a resident agent, while c. 156D § 5.01 requires a corporation to maintain a registered agent and registered office — so a Massachusetts corporation looking for a “resident agent” field will not find one. And Nevada is no longer on this list: NRS Chapter 78’s old resident-agent scheme was superseded in 2013 by NRS Chapter 77, the Model Registered Agents Act, and the Secretary of State’s forms have said registered agent ever since. If you have older Nevada paperwork that says resident agent, it is describing the same role under the old name. Everywhere here, match whichever term the form in front of you prints.

Pennsylvania is the outlier. Instead of naming a person or company as your agent, Pennsylvania asks for a registered office, which is an address in the state where process can be served. You can list your own Pennsylvania street address, or you can use a Commercial Registered Office Provider, which supplies the address on your behalf.

The function is the same as everywhere else, receiving legal documents and state mail at a reliable in-state location. Pennsylvania just frames the requirement around the address rather than around the agent. If you are filing in Pennsylvania and looking for a registered agent field, look for registered office instead.

California does not use registered agent on its forms. Corporations Code § 17701.13 requires every LLC to designate and continuously maintain an agent for service of process, and that is the wording on Form LLC-1 when you form and on Form LLC-12, the Statement of Information you file every two years after that. The duties are the same as a registered agent’s — a real California street address and availability to be served — so if a service quotes you for a California registered agent, they mean this.

New York uses the phrase differently again: there the Secretary of State is your agent for service of process by law (NY LLC Law § 301), and any private agent you name is an addition on top (§ 302). Elsewhere, “agent for service of process” is usually just a description of what every registered, statutory and resident agent does, rather than a separate appointment you make.

Behind all the naming, there is one distinction that genuinely changes something: commercial versus noncommercial. A commercial registered agent is a company that has filed a listing statement with the state and formally registered as a professional agent, often under the Model Registered Agents Act adopted by states like Wyoming, Montana, and others.

A noncommercial agent is anyone else who serves, such as you, an employee, a friend, or an attorney. The practical difference is administrative. When a commercial agent changes its own address, it updates one filing and every business it represents moves automatically, instead of each entity filing a separate change. Some state databases let you select a listed commercial agent by name or number rather than typing a full address. This is the only difference that carries real weight, and it has nothing to do with whether your state says statutory, resident, or registered.

The rule is simple: use the exact term printed on your state’s form. Do not translate it. If Arizona or Ohio asks for a statutory agent, write statutory agent. If Kansas, Maryland, Massachusetts, Michigan, Rhode Island or Puerto Rico asks for a resident agent, write resident agent. If California asks for an agent for service of process, write that. If Pennsylvania asks for a registered office, provide the office address. If West Virginia asks for an agent of process, write that — and only if you are naming one, since the field there is optional. Everywhere else, the form will say registered agent.

Matching the state’s wording prevents rejected filings and keeps your records consistent. The underlying appointment is the same in most places regardless of the label, so you are rarely choosing between different services — only using the right word in the right box.
