Three codes serve the same numbering region
Florida’s Public Service Commission identifies 305, 786 and 645 as overlays covering Miami-Dade County and the Florida Keys. New 645 assignments began in August 2023. An overlay adds numbers to the same geographic region; it does not require existing customers to change their numbers.
Miami is not the whole of South Florida
A Miami contact number can fit a Miami-Dade or Keys-focused business. If your service territory also includes Broward or Palm Beach, describe those locations directly and compare their local area codes through the Florida directory. Do not assume every South Florida customer associates the same code with their neighborhood.
Test spoken digits with your actual callers
If your team serves customers in more than one language, test the full number in the languages staff use. Compare a repeating pattern with a vanity spelling before committing. Keep the numeric version visible on menus, signs and mobile pages so callers do not have to decode a word.
Plan separate paths for reservations and business inquiries
A hotel service, charter business or event supplier may receive both visitor bookings and supplier calls. Decide whether those should reach one team or separate destinations. Your carrier or phone platform provides routing; the number purchase supplies the number and transfer credentials.
Use the market report as context
The 305 report describes current ED catalog asking prices and patterns. Compare that context with the specific 305, 786 or 645 listing you want. Confirm the receiving carrier can take it, then test the completed line before changing booking confirmations or property materials.
