Area Code for Miami
Miami uses three area codes: 305 (1947), 786 (1998 overlay), and 645 (2023 overlay). Full guide covering history, neighborhoods, scams, and business numbers.
Miami runs on three area codes at once. 305 has been the city’s identity since 1947 — so embedded in local culture that rapper Pitbull built a nickname and a record label around it. 786 arrived in 1998 as an overlay when Miami’s explosive growth exhausted available 305 numbers. 645 launched in August 2023 as the newest overlay, approved by the Florida Public Service Commission as South Florida’s population kept climbing.
All three cover the same territory: Miami-Dade County and the Florida Keys. None carries more prestige than the other for routing or pricing, but 305 carries a weight no other area code in the US quite matches.
What’s the area code for Miami?
Miami-Dade County and the Florida Keys are served by three overlapping area codes:
| Code | Established | Coverage | Notes |
|---|---|---|---|
| 305 | 1947 | Miami-Dade + Florida Keys | Original code; all of Florida until 1953 splits |
| 786 | March 1, 1998 | Miami-Dade + Florida Keys | First overlay; triggered by cell/pager boom |
| 645 | August 4, 2023 | Miami-Dade + Florida Keys | Second overlay; FL PSC-approved Feb 2023 |
An overlay means a new area code is added to the same geographic footprint as the existing codes. No existing customer changes their number. Only lines provisioned after the overlay launch date may receive numbers from the new code.
10-digit dialing (area code + 7-digit number) has been standard in the 305/786 region since the 786 overlay launched in 1998. The addition of 645 required no further change.
Miami area codes by neighborhood
All three Miami codes cover Miami-Dade County in full. You cannot identify a caller’s neighborhood from the area code alone. That said, the density of each code shifts by era — older businesses and landlines skew toward 305, while mobile lines and newer businesses from 1998 onward are often 786.
| Neighborhood | Character | Area code you’ll encounter |
|---|---|---|
| Downtown Miami | Financial district, government offices, older commercial stock | 305 dominant; 786 common |
| Brickell | Miami’s banking and finance hub, high-rise condos, newer build | 305/786 mix; some 645 for newest lines |
| Wynwood | Arts district, creative agencies, galleries, newer hospitality | 786 frequent; 305 for legacy tenants |
| Coral Gables | University of Miami, Mediterranean architecture, established law and finance firms | 305 dominant due to older institutional base |
| Miami Beach | Tourism, hospitality, Art Deco, international clientele | 305/786 split; heavy tourist traffic from outside |
| Florida Keys | Monroe County resort towns: Key Largo to Key West | 305/786 (Monroe added to 786 overlay Sep 2001) |
For businesses targeting a specific Miami neighborhood, any of the three codes signals a Miami presence equally well to inbound callers.
History of Miami area codes
The story of Miami’s area codes is really the story of Florida’s growth.
1947. AT&T launched the North American Numbering Plan (NANP) with 86 original area codes. Florida received a single code — 305 — covering the entire state.
1953–1965. Florida’s population expanded fast enough to require splits. Area code 813 was carved out for western Florida (Tampa), and 904 for the northern region (Jacksonville). The 305 footprint shrank to central and south Florida.
1988. 407 was added for the east coast and the Orlando region as theme-park tourism drove demand for lines.
September 1995. Broward County — Fort Lauderdale and its suburbs — split off from 305 and became 954. The split caused technical disruptions and frustration; some businesses filed complaints over the forced renumbering.
March 1, 1998. Rather than split Miami-Dade away from the 305 code (which would force millions of existing customers to change numbers), regulators chose an overlay: 786 was added to the exact same geography. New lines got 786; existing 305 numbers stayed put. Mobile phones and pagers were the primary driver — wireless lines were consuming number blocks far faster than legacy landlines.
September 1, 2001. Monroe County (the Florida Keys) was formally added to the 786 overlay, completing the current geographic boundary of both codes.
February 1, 2023. The Florida Public Service Commission approved a third overlay. PSC Chairman Andrew Fay stated: “While minimizing the impact to current customers, the commission must plan for the continuing influx of new residents and businesses to the region — a testament to South Florida’s growing economy.”
August 4, 2023. Area code 645 went live. New subscribers in Miami-Dade and the Florida Keys may now receive 645 numbers. All existing 305 and 786 holders kept their numbers unchanged.
The regulatory authority for US area code assignments is the North American Numbering Plan Administration (NANPA). Overlay decisions in Florida are approved by the Florida Public Service Commission.
305 as cultural identifier
No area code in the United States carries a cultural identity like 305.
Armando Pérez — known globally as Pitbull — was born and raised in Miami and built his artist identity around the code. He calls himself “Mr. 305,” named his record label Mr. 305 Inc., signed a vodka brand (Voli 305), and references the code across his catalog. His 2004 debut album, M.I.A.M.I., stands for “Money Is A Major Issue” — a Miami anthem that made the 305 area code recognizable in markets far outside Florida.
Singer Enrique Iglesias ran his social accounts as @enrique305 for years, another signal of how the code functions as Miami identity.
305 Magazine is a regional lifestyle publication that literally named itself after the code. The Miami Heat and Miami Marlins both invoke “305” in fan campaigns and merchandise — the code reads as team and city in a single syllable.
The cultural resonance runs deeper in Miami’s bilingual market context. More than 70% of Miami-Dade residents are Hispanic, and a significant portion conduct business primarily in Spanish. A 305 number on a business card carries trust signals in both English and Spanish-speaking contexts. “El 305” is shorthand for Miami across Latin America in a way that “Miami area code” simply isn’t.
This cultural weight is why businesses that have no physical Miami presence still seek 305 numbers, and why inventory in desirable 305 blocks stays tighter than in equivalent overlay codes.
Miami area code spam and scams
The 305 and 786 codes appear in a disproportionate share of reported spam calls. Florida recorded 159,307 fraud cases in 2024, with total losses of $866 million.
The top reported spam call types from 305/786 numbers include auto warranty scams (10%), Medicare and Medicaid impersonation (8.4%), health insurance offers (8%), and mortgage loan solicitations (6.4%).
Miami’s bilingual market creates a specific scam pattern: IRS impersonation calls in Spanish and English. Callers claim your Social Security number has been suspended or that federal agents are en route. The FCC notes that spoofed caller ID makes it trivial to fake a 305 or 786 number even when the call originates overseas.
A few firm rules for evaluating 305/786 calls:
- The IRS, Social Security Administration, and Customs and Border Protection do not initiate contact by phone. They mail first.
- No government agency demands immediate payment by gift card, wire transfer, or cryptocurrency.
- “Your Social Security number has been suspended” is a scripted scam line — Social Security numbers cannot be suspended.
For legitimate businesses, the solution is STIR/SHAKEN (learn more in our glossary) — a caller-ID authentication framework that lets carriers verify your calls carry an A-level attestation, meaning the call genuinely originates from the number shown on caller ID. DialPhone applies STIR/SHAKEN A-attestation to 305 and 786 numbers, which significantly reduces the chance your legitimate Miami business calls get flagged as “Spam Risk” or rejected outright.

Famous companies and brands in Miami area codes
The 305 area code anchors some of the most recognizable corporate names in the country:
Carnival Corporation — the world’s largest cruise operator, headquartered in Miami with a 305 number, runs Carnival Cruise Line, Princess Cruises, and Holland America Line from its Doral campus.
Royal Caribbean Group — headquarters on Biscayne Bay, 305. The group runs Royal Caribbean International, Celebrity Cruises, and Silversea from Miami.
Burger King — the fast-food chain’s global headquarters sits in Miami’s Brickell area. The company that invented the Whopper is a 305 company.
Lennar Corporation — a Fortune 500 homebuilder headquartered in Miami. One of the largest residential construction companies in the US, dialing from 305.
Telemundo — the Spanish-language broadcast network has its headquarters in Miami, reflecting the city’s status as the media capital of Latin America.
Univision — another Spanish-language media giant with major Miami operations, serving the same bilingual market.
The concentration of hospitality (cruise lines), real estate (Lennar), and Spanish-language media (Telemundo, Univision) in a single area code reflects exactly the industry mix that defines Miami-Dade’s economy.
How to get a Miami business phone number
A Miami 305 or 786 number signals local presence to customers and carries the city’s cultural credibility. You do not need a physical Miami office to get one.
Step 1: Choose a cloud VoIP provider. Look for one that offers 305 and 786 inventory, STIR/SHAKEN A-attestation, and bilingual features if you serve Spanish-speaking customers.
Step 2: Sign up and search available numbers. Filter by area code (305 or 786) and pick from live inventory. 305 blocks run tighter than 786 due to demand — if 305 availability is low, a 786 number carries equal validity.
Step 3: Assign the number. Route it to your mobile, desktop app, or team queue. Set business hours, an auto-attendant, and after-hours handling.
Step 4: Configure bilingual coverage. For a Miami market, Spanish-language call handling is not optional — it is expected. DialPhone’s AI receptionist handles EN/ES calls with mid-call language switching, which matters for a county where 70%+ of residents are Hispanic.
Step 5: Enable STIR/SHAKEN attestation. This is the single most important step for ensuring your Miami calls are not labeled as spam, particularly in a market where 305/786 spam rates are elevated.

South Florida area codes: the full picture
Miami’s three codes sit within a broader South Florida numbering landscape. Businesses that serve the tri-county metro — Miami-Dade, Broward, and Palm Beach — will encounter all six codes:
| County | Cities | Area codes |
|---|---|---|
| Miami-Dade | Miami, Coral Gables, Hialeah, Homestead | 305, 786, 645 |
| Broward | Fort Lauderdale, Hollywood, Coral Springs | 954, 754 (overlay) |
| Palm Beach | West Palm Beach, Boca Raton, Delray Beach | 561, 728 (overlay) |
A 305 number does not reach callers in Fort Lauderdale or Boca Raton for free under a Miami-local plan — those are separate area codes in different counties. For Florida businesses serving the full tri-county corridor, running dedicated numbers in 305 (Miami), 954 (Fort Lauderdale), and 561 (Palm Beach) is the standard multi-market setup.
Miami area code FAQ
Miami area code FAQ
What is the area code for Miami?
Miami uses three area codes: 305, 786, and 645. All three are overlays that cover the same geography — Miami-Dade County and the Florida Keys.
305 is the original code, assigned in 1947. 786 was added in 1998 to handle rapid number exhaustion driven by cell phones and pagers. 645 launched on August 4, 2023, as a third overlay when 305 and 786 again ran low on available numbers.
Is Miami 305 or 786?
Miami is both. 305 and 786 (and now 645) are all valid Miami area codes that cover the exact same territory: Miami-Dade County and the Florida Keys.
305 is the original code and carries more cultural cachet — rapper Pitbull adopted 'Mr. 305' as his nickname. 786 is equally valid and far more common for newer numbers issued since 1998. Neither code tells you anything about which neighborhood the caller is in.
What is the 645 area code?
645 is Miami-Dade County's newest area code, activated on August 4, 2023. The Florida Public Service Commission approved it after 305 and 786 were nearing exhaustion due to South Florida's population growth and the surge in mobile devices.
Existing customers kept their 305 or 786 numbers. Only new lines assigned after August 2023 may receive 645 numbers. Local calls in the region still use standard 10-digit dialing.
What area code is Coral Gables, Miami Beach, or Brickell?
All of Miami-Dade County shares the same three overlapping area codes: 305, 786, and 645. That means Coral Gables, Miami Beach, Brickell, Wynwood, Downtown Miami, and every other Miami-Dade neighborhood can have numbers in any of the three codes.
You cannot identify a caller's neighborhood from their area code alone. The three codes overlap completely across the county.
What are the area codes near Miami in South Florida?
South Florida uses six area codes across three counties. Miami-Dade County: 305, 786, and 645 (all overlapping). Broward County (Fort Lauderdale): 954 and 754 overlay. Palm Beach County (West Palm Beach, Boca Raton): 561 and 728 overlay.
The region does not share a single area code — each county has its own set, so a Fort Lauderdale 954 number and a Miami 305 number are distinct even though the cities are 30 miles apart.
How do I get a Miami 305 or 786 business phone number?
Sign up with a cloud VoIP provider, search available inventory by area code (305 or 786), and pick an available number. Setup takes under 10 minutes. No Miami office address is required — virtual numbers route to your mobile, desktop, or team wherever you work.
If you want to port an existing Miami number to a new provider, submit a Letter of Authorization and a recent phone bill. US local ports typically complete in 2 to 5 business days. Keep the old account active until the port confirms.
Are 305 and 786 area code calls safe to answer?
Most calls from 305 and 786 are legitimate. Florida's top reported scam types from these codes include auto warranty calls, Medicare/Medicaid impersonation, health insurance offers, and IRS impersonation — often in both English and Spanish given Miami's bilingual market.
If you receive an unsolicited 305 or 786 call claiming to be from the IRS, Social Security Administration, or a government agency demanding immediate payment, it is almost certainly a scam. Real government agencies contact you by mail first. Report suspicious calls to the FTC at reportfraud.ftc.gov.
