(305) Area Code Business Phone Numbers
The 305 is Miami's original phone code, established in 1947 as one of the first area codes in the country. Locals treat it like a badge, so having a 305 number tells customers you're part of the city, not calling in from somewhere else.

When 305 launched in 1947, it covered the entire state of Florida. Growth chipped away at that footprint over the decades, and by 1998 Miami-Dade needed the 786 overlay just to keep up with demand from cell phones and fax lines[1]. A third overlay, 645, has since been added on top of that.
Miami-Dade sits at number one nationally for small business growth, with roughly 4,900 new businesses opening in 2024 alone[2]. The mix is wide: cafes in Little Havana, logistics firms out by the port, real estate brokers in Brickell, and a huge Spanish-speaking customer base that expects you to answer the phone.
Down here, a 305 number reads as authentic. Buyers see an out-of-state caller ID and let it ring, but a 305 gets picked up. It's the difference between being treated like a neighbor and being treated like a telemarketer.
Cities Served by the 305 Area Code
The 305 covers Miami-Dade County and the Florida Keys, from Aventura in the north down to Key West. Below are 26 of the cities included in the coverage area.
Features Built for Miami Businesses
A 305 number is the starting point. What you do with it is what actually moves the needle for a small business in a market this crowded.
Auto Attendant
Route callers in English or Spanish, send sales to one line and service to another, and never miss a lead because someone hit voicemail during lunch.
Call Recording
Pull up any past call for training, dispute resolution, or just confirming what a customer actually agreed to. Handy when a booking gets contested.
AI Transcription
Every voicemail and recorded call comes back as searchable text, so you can scan a busy morning's messages in about a minute.

Take calls from the shop, the food truck, or a boat off Key West. Your business line goes wherever the workday takes you.

Tonet bills by the day instead of a monthly lump sum, so if you add or drop a user mid-month you only pay for what you used.
Frequently Asked Questions
Can I still get a 305 number, or only 786?
Yes, 305 numbers are still available, though they're tighter than 786 or the newer 645 overlay. Grab one while inventory lasts if you specifically want the original Miami code.
Do I need to be in Miami to have a 305 number?
No. You can run a 305 line from anywhere in the country. It just needs to ring on a device you actually answer, whether that's a desk phone in Doral or a mobile app in Denver.
Can I port my existing 305 number to Tonet?
Yes. If you already own a 305 number with another carrier, you can port it over at no extra charge. Bring your existing number and keep everything you've built.
How much does a 305 business line cost?
Plans start at $10 per user per month, billed daily so you're not locked into a full month if things change. Extra numbers are $2.50 each per month, and there are no contracts.
Does the 305 area code cover the Florida Keys?
Yes, all the way down to Key West. Same code across Miami-Dade and the Keys, so a local number works whether you're on Biscayne Boulevard or Duval Street.
