305 numbers for Downtown Miami businesses

Downtown Miami is the county's legal center. The federal courthouses are here, and in November 2025 the new Osvaldo N. Soto Miami-Dade Justice Center opened across Flagler Street from the 1928 courthouse tower, which the civil courts then left. Law firms and the services around the courts fill the towers nearby.

On Biscayne Boulevard stand the Kaseya Center, home of the Miami Heat, and the Adrienne Arsht Center for the Performing Arts. Brightline trains have run from MiamiCentral station since 2018, and PortMiami, which calls itself the Cruise Capital of the World, sits just across the water.

Numbers that fit

A round-hundred main line (2100, 4500) reads as settled on letterhead and in a court filing, and leaves the numbers next to it for direct lines. Visitor businesses do well with a repeat that is easy to read off a sign.

A 305 number isn't tied to one town or one part of Miami. Each listing shows the city the number is listed under, and on a mobile phone or an internet phone service it works wherever you are.
