407 Area Code: Orlando, Kissimmee and the 321 and 689 Overlays

Where does 407 cover?

The Florida Public Service Commission's description is short: "Orange, Osceola, Seminole and parts of Lake and Volusia Counties in Central Florida". NANPA's exhaust report is more precise, listing the rate centres — the local calling zones numbers are assigned to — that make up the 321/407/689 area: Apopka, Celebration, East Orange, Geneva, Kenansville, Kissimmee, Lake Buena Vista, Montverde, Orlando, Oviedo, Reedy Creek, Sanford, Saint Cloud, Windermere, Winter Garden, Winter Park and West Kissimmee.

Three of those names will be familiar to anyone who has visited: Lake Buena Vista, Reedy Creek and Celebration are the rate centres covering the theme-park district, so the resorts' numbers come from the same pool as downtown Orlando's.

The Brevard point matters because several directories and number-vendor pages list Titusville or Melbourne under 407. They have never been 407 since the 2000 split, and a 407 number cannot be issued there.

Because the Commission names the three core counties whole, any city inside them is a 407 city. Reading the county lines rather than the rate-centre names:

407, 321 and 689: three codes, two different relationships

689 is a conventional overlay: a third code for the same territory, issued once 407 ran short. 321 is stranger. In 1999 it was introduced in two phases at once — as an overlay on Orange, Osceola, Seminole and parts of Volusia and Lake, and as a split that took Brevard County out of 407 altogether. So Orlando has 321 numbers alongside its 407 ones, while in Brevard 321 is the only code.

Why 321 stopped being issued in Orlando is in the Commission's own file. In 2002 it reserved every unassigned 321 prefix for Brevard County; the 2018 staff memo notes that NANPA had nonetheless assigned 56 of them outside Brevard over the years, and that none had been since 2015. NANPA's database now carries the rule as a note on the code: 321 prefixes are assigned only in Brevard's five rate centres — Cocoa, Cocoa Beach, Eau Gallie, Melbourne and Titusville. An Orlando 321 number is therefore one from a prefix assigned before 2015 — numbers can be reassigned or ported, so the code does not date any one subscriber's line — and new Orlando prefixes are 407 or 689.

How do you dial a 407 number?

Ten digits for every local call — area code plus number, no leading 1. That rule is older than most people realise: NANPA's planning letter set mandatory ten-digit dialing for all calls "both within and between the 407 and 321 NPAs" from 1 December 1999, after a permissive period that started on 1 April 1999. When 689 arrived in 2019 nothing changed; the Commission's fact sheet simply told people to "continue to dial 10 digits".

The one part of this complex touched by the FCC's 2021 ten-digit order for the 988 crisis line was Brevard. The FCC's list names "321 (Brevard County only)", because Brevard still allowed seven-digit calls; Orlando had been ten-digit for twenty-two years by then.

All of central Florida is Eastern. The state's Central-time counties lie west of the Apalachicola River, where the federal zone boundary runs. Daylight saving runs from the second Sunday in March to the first Sunday in November, as everywhere else in the state.

A history of area code 407

407 started large and has been giving territory away ever since — first to 561 on the Atlantic coast, then to 321 on the Space Coast — before finally gaining a code in 2019 instead of losing one.

1. 1988

   407 splits from 305

   Assigned on 20 March 1987 and in service from 16 April 1988, 407 takes central Florida and the Atlantic coast north of Broward County out of 305, Florida's original code.

2. 1996

   561 takes the coast

   Palm Beach and the Treasure Coast leave 407 for 561, in service from 13 May 1996.

3. 1998

   The Commission approves 321

   Order PSC-98-1761-FOF-TL approves what the Commission later calls "a limited area code overlay (321)".

4. 1999

   Ten-digit dialing, and a split

   Permissive ten-digit dialing from 1 April; mandatory from 1 December. From 1 November, Brevard County begins its move to 321 — Planning Letter 168 sets both schedules.

5. 2000

   321 numbers in Orlando; Brevard leaves 407

   The first 321 prefixes in the Orlando overlay take effect on 15 January. On 1 October, dialing 407 for a Brevard number stops working.

6. 2002

   689 approved — and shelved

   On 25 March the Commission approves a 689 overlay for July. On 31 May it suspends it indefinitely: with about 200 prefixes still unused, 407 was judged to have close to nine more years in it. It had seventeen.

7. 2018

   Nineteen prefixes left

   NANPA writes to the Commission on 16 May: 19 prefixes remain and 407 will exhaust within a year. The Commission takes up the suspended overlay at its 10 July agenda.

8. 2019

   689 goes live

   From 4 June 2019 new lines in the Orlando area may receive 689 numbers. No dialing change is needed.

Can you still get a 407 number?

Yes, while a carrier has 407 prefixes to issue from. The Commission's fact sheet was candid when 689 launched: customers requesting "new service, an additional line, or in some cases, moving their service" may receive a 689 number. Which code you get is decided by the carrier's inventory, not by your address.

The overlay settled the supply question for a generation. NANPA's April 2026 exhaust analysis projects the combined 321/407/689 area to run out of prefixes in the first quarter of 2051, and Brevard's 321 on its own in the second quarter of 2045. The combined forecast has wandered — Q3 2040, Q1 2041, Q3 2059, Q4 2044, Q2 2049, now Q1 2051 across the last six rounds — which is a reminder to read these as planning estimates. NANPA's record lists the area as not in jeopardy and with no relief planning in progress.

Is 407 a country code?

No. In the ITU's list of country codes, 40 is Romania, and Romania's numbering plan uses 7 as the first digit of mobile numbers — so "+40 7…" is a Romanian mobile, which is what a number written "+407…" will be read as. Orlando is in country code +1, shared by the United States and Canada: from abroad, dial +1 407 and the seven-digit number.

Area codes around 407

Central Florida's codes were cut from four different parents over three decades, which is why the map around Orlando looks the way it does:

Tampa Bay, to the south-west, is covered in our 727 guide — a code that, unlike 407, has never been overlaid. The full list of guides is on the area codes page.

What a 407 number tells you about a caller

That the number was issued in the Orlando area — and, if it is a 321 number, possibly in Brevard instead. It says nothing about where the caller is now: a 407 mobile stays 407 when its owner moves to Jacksonville, and caller ID can be set to a number the caller does not own, which the FCC calls spoofing.

For a business calling out from 407, whether the far end sees the number intact or sees a warning label is a question of route and reputation, not digits. The mechanics are in our guides to CLI vs NCLI routes and area codes and call routing.
