A registered agent is the official point of contact that receives legal and state documents on behalf of your business. Every LLC and corporation in the U.S. is legally required to maintain one in each state where it operates. Start below with what the law actually requires and how to look up any company's agent of record for free — provider comparisons come after that.
A registered agent is a person or service with a physical address in the state, available during normal business hours, designated to accept official correspondence for your business. States require this so there is always a reliable way to deliver legal and government notices. Using a professional service protects your privacy and ensures nothing important is missed. Here's what a registered agent does:
You never need to pay to find out who a company's registered agent is. Every state's Secretary of State business entity search publishes the agent's name and registered office address alongside entity status, formation date, and annual report history, at no cost. If you are checking a vendor, a landlord, or a counterparty before signing, that free lookup is the authoritative record — a paid service is only repackaging it.
You can also act as your own registered agent in nearly every state, provided you have a physical street address there (not a P.O. box) and are available during business hours to accept service. The real costs of doing that are privacy — your address becomes a public filing — and risk: if a process server cannot find you, a default judgment can be entered without you knowing. Owners who work from home, travel, or operate in more than one state are the ones who most often pay for a service instead.

Yes. You must maintain a registered agent in your formation state and in every state where you foreign-qualify to do business — that is, where you register to legally operate outside your home state. If you expand into new states, each one requires its own agent with a physical in-state address. Rather than managing separate agents everywhere, most multi-state businesses use a single national provider that covers all 50 states from one account, keeping compliance and annual reports centralized as they grow.

Every LLC and corporation in the U.S. is required to have a registered agent. Here is what a registered agent does, who qualifies, and what happens if you do not have one.
Read the guideForming an LLC is the easy part. Staying compliant — registered agent, annual reports, and licenses — is where most small businesses slip up. Here's what business compliance actually means and how to spot the gaps.
Read the guideBefore you wire money, sign a contract, or extend credit, a 5-minute public records check can tell you whether the business on the other side of the deal actually exists — and whether it's in good standing.
Read the guideIf you have decided to hire an agent rather than serve as your own, these are the providers we see used most often. Pricing changes often — always confirm current rates on the provider's site. Only Harbor Compliance is a partner we can link to today; the others are listed for comparison without a link.
Harbor Compliance sits at the compliance-management end of the market rather than the cheap-agent end. Beyond acting as agent of record, it tracks annual report deadlines, franchise tax filings, foreign qualification, and industry licensing across every state a company is registered in, which is the part most owners actually get wrong. That makes it a fit for businesses operating in several states or in regulated fields — construction, healthcare, insurance, nonprofit fundraising — where a missed license renewal costs far more than the agent fee. The trade-off is that pricing is quoted rather than a flat headline rate, and a single-state solo LLC will pay for capability it may not need. Ask specifically what is bundled versus billed per filing before you sign, and confirm which states are included in the quote.
Best for: Multi-state or regulated businesses that need licensing and annual-report tracking, not just an address.

Northwest built its reputation on two things: not using your home address on public filings, and not upselling. Documents served on the agent are scanned and posted to your account the same day, and support is handled by staff rather than a call queue. For a single-state LLC that mainly needs a reliable in-state address and prompt forwarding of service of process, this is usually the simplest arrangement. What it does not do is manage your licensing calendar for you across many states, so growing companies sometimes outgrow it. Note that whichever provider you choose, the agent's name and registered office become part of your public filing — that is exactly what you will see when you look a company up on a Secretary of State portal.
Best for: Single-state LLCs and privacy-conscious owners who want an address and clean forwarding.
ZenBusiness bundles registered agent service with entity formation, operating agreements, EIN help, and a compliance dashboard, which appeals to first-time founders who want one account for everything. If you have not formed the company yet, that packaging can be cheaper than buying formation and agent service separately in year one. Read the renewal terms carefully, though: introductory formation pricing and the ongoing agent fee are separate lines, and the second-year cost is what matters. Remember that you never have to pay anyone to check a filing — entity status, registered agent of record, and annual report history are free to look up on your state's business search, and only the filing itself carries a state fee.
Best for: New owners forming an entity who want agent service bundled with the filing.
LegalZoom is the most established name in the category and the one most likely to be useful when your question is legal rather than administrative — it pairs registered agent service with attorney consultations, trademark filings, and contract templates through its network. That breadth costs more per year than a bare-bones agent, and the agent product itself is not meaningfully different from cheaper competitors. Consider it when you expect to need counsel alongside compliance work, and skip it if all you need is a statutory address. Either way, changing agents later is routine: you file a statement of change with the Secretary of State, pay a small state fee, and the new agent typically prepares the form for you.
Best for: Owners who want legal services and compliance from the same vendor.
