Our Downtown Miami Building — 150 SE 2nd Ave

• Real commercial address in Downtown Miami's central business district
• Steps from Metromover stations and Bayfront Park
• Bilingual support, no long-term contract

This is the actual building. 150 SE 2nd Avenue, Miami FL 33131. You can drive by it, you can verify it on Street View, and during business hours you can take the elevator up and meet the team that handles your mail. We are not a reseller operating space from somebody else's lobby — we hold the lease, we staff the office, and the address that goes on your LLC formation, your bank application, and your Google Business Profile is the same address printed on the lobby directory downstairs. The rest of this page describes the building, how to reach it, how mail moves through it.

The address (verifiable on Street View)

150 SE 2nd Avenue is in Downtown Miami's central business district, just north of the Miami River. We hold a dedicated office — our name on the building directory and the lease in The X Office's name. What you get is your own PMB, the format USPS expects for a commercial mail address (USPS DMM §508) — not a floating mailbox identifier inside someone else's space. If your address is ever questioned in a Florida Sunbiz inquiry (Sunbiz) or a Form 1583 audit (USPS Form 1583), the chain of evidence starts with a building you can point a camera at.

Inside our office — what's on-site and how mail moves

Our office has a secured mailroom where your inbound mail is logged and scanned, and the operations team that handles everything in between. Every inbound piece is logged at intake with sender, postmark date, and a photograph of the unopened envelope, then routed to your dashboard within one business day. Standard scans (envelope front, plus contents on request) post the same day for items received before noon and the next business day for anything later. The Form 1583 on file for your account is what authorizes us to receive and open mail in your name (USPS Form 1583); it lives in our compliance binder and on file with USPS, and a copy is available to you on demand.

How to get here

The fastest way into the building from anywhere in the area is the Metromover, which is free to ride and runs every couple of minutes during business hours (Miami-Dade Metromover — free fare downtown circulator). The Knight Center and First Street Metromover stations are both within a few minutes walk of our entrance. If you drive, there is paid garage parking in the building and additional street and surface options nearby; we will tell you in advance which entry to use. From Miami International Airport the ride is roughly fifteen to twenty minutes by car outside rush hour, and the Metrorail-to-Metromover combination is the rail option if you would rather not drive.

A secure, verifiable building

The office is locked, the mailroom is locked, and the building lobby is card-access controlled. Inside the mailroom, each client's mail is kept secured and separated per client, then logged, scanned, and routed to you digitally — nothing about the service requires you to be here. Cameras cover the lobby, the elevator bank, and the main office entrance. It's a real building you can verify on Google Street View, so a regulator, a vendor, or an institution checking your address sees a working office — and you never need to come in, because everything reaches you online.

Why Downtown Miami — and the compliance details that ride along

Downtown Miami's central business district is home to a dense concentration of finance, law, and professional-services tenants — the district is recognizable on a bank's KYC screen, and the ZIP code 33131 is shared by major South Florida banks and institutions. For a non-resident founder forming a Florida LLC, that context is not decorative: it is the signal that helps a reviewer at an online bank classify your address as a working business location rather than a virtual mailbox. The neighborhood is walkable, served by the free Metromover, and close to Bayfront Park and the Miami River waterfront. The underlying compliance is straightforward: TXO operates its own office as a USPS-authorized commercial mail operator with a lease in our LLC's name, the suite-and-floor format that USPS expects for commercial mail addressing (USPS DMM §508), and registration on the Florida Division of Corporations public registry (Sunbiz).
