You formed the LLC at the kitchen table, typed in the only address you had, and hit submit. A few weeks later the letters start. Offers to file your annual report for a fee. Loan offers. Insurance quotes. Then you search your company name and there it is, your apartment number, on a public record anyone can pull up for free.
That record is Sunbiz, the Florida state website where every LLC is registered and where anyone can look one up. What you put there is public, and it stays public. A business address gives your company a place to live that isn't your living room.
What you get
- A Miami street address in an office building: "2125 Biscayne Blvd, Suite 300 #" plus your mailbox number, Miami, FL 33137. It's a real building on Biscayne Boulevard, not a P.O. box at the post office. Here's what the "#" in your address means.
- Mail handled by people, in the building: our team receives every letter on site and you see a photo of each envelope in the app. Ask for a scan, have it forwarded, or pick it up in person.
- Form 1583 done online: USPS, the US Postal Service, requires a short form called PS Form 1583 before anyone can receive mail for you. You sign it on a quick video call with an online notary, and that's included in every plan.
- More on the Business plan: a Miami phone number that rings your own phone, a service agreement you can show as proof of your business address, and room for packages.
- A desk or a room when you need one: meeting rooms by the hour and day offices in the same building, for the client meeting you'd rather not hold at a coffee shop.
Where it fits on your Sunbiz record
Florida asks for several addresses, and they don't all follow the same rules. Here's the honest version.
- Mailing address: yes. This is where the state sends your LLC's mail. It can even be a P.O. box, so a commercial street address is well within the rules.
- Manager or authorized member address: yes. The annual report lists at least one person who runs the company, with an address. Sunbiz's own help pages accept a P.O. box there, so it doesn't have to be your home.
- Principal office: it depends. This line has to be a street address, and it means the place the business is actually run from. Whether a mailbox-style address counts is a gray area, and we explain it in our guide on using a virtual office as your LLC's address.
- Registered agent: no. The registered agent is the person or company that accepts lawsuits for your LLC, and Florida wants someone physically there during business hours to do it. We don't offer that service, so you'll need a separate registered agent.

Where else you'll use it
The Sunbiz record is just the start. Most owners put the address on their website footer, invoices, contracts and email signature. It's also a good mailing address for the IRS, the US tax agency, which still writes to companies on paper.
One honest caveat. Banks and payment companies set their own address rules, and some don't accept virtual office addresses as the company address. Mercury, an online business bank, says so plainly. So ask yours before you change anything there.
How it works
- Pick a plan. Plans start at $39 a month. Pay yearly and you get 2 months free.
- Verify and sign. You get a link, show your ID on a short video call with an online notary and sign Form 1583. It usually takes minutes.
- Get your mailbox number. Your address is ready to use, and mail starts showing up in the app.
- Update Sunbiz. Change your mailing address online on Sunbiz whenever you like, or do it when you file your annual report between January 1 and May 1. Our Florida LLC annual report guide covers that step.
Why Biscayne Boulevard
2125 Biscayne Blvd sits in Edgewater, on the main boulevard between Downtown and Midtown Miami. It's an address people in Miami recognize, and clients abroad tend to know the name too. And because our team works in the building, a real person handles your mail and opens the door when you come by. Read more about the building and the neighborhood.
