Florida area codes
Florida uses 23 area codes. The oldest is 305, in service since 1947; the newest is 324, from 2024. Across them 11,207 of 18,078 possible number blocks are allocated, 62.0% of capacity. 407, 561, 786, 850, 305, 904, 813 and 954 are at or past 95%, which is why new numbers there come from overlays rather than the original code. AT&T holds 27.3% of the 11,207 assigned blocks across the state, ahead of T-Mobile at 15.5%; a further 11.2% sits with CLEC and VoIP holders outside the national carriers. In the 33 days to 30 October 2026, FTC complaints named a Florida caller ID 17,638 times – 7.7% of all complaints in the window, most often 813 with 1,926 (3rd of 422 nationally). The state spans 2 time zones (Eastern and Central); 448 and 850 cross a zone boundary alone. NANPA records 380 rate centers across the state's codes.

Block share is share of allocated number blocks, not of subscribers. Complaint counts cover 28 Sep – 30 Oct 2026 and reflect spoofed caller IDs as much as real calls.
How full Florida’s codes are
A code holds at most 786 blocks of 10,000 numbers each. When a code fills up, the administrator does not reclaim numbers – it adds an overlay, and from then on new numbers in the same area come from the new code.
Full or nearly full
Who holds the number blocks
Counted from every assigned block in the state: 11,207 blocks, each with the holder NANPA recorded for it. Percentages are measured, not estimated.
| Holder | Blocks | Share of Florida | Largest in |
|---|---|---|---|
| AT&T | 3,064 | 27.3% | 9 codes |
| T-Mobile | 1,733 | 15.5% | 2 codes |
| Other CLEC / VoIP | 1,259 | 11.2% | 7 codes |
| Verizon | 1,115 | 9.9% | – |

“Other CLEC / VoIP” is not one company: it is every holder outside the national carriers counted together, which is what resellers and app-based numbers look like in the records. This is allocation, not subscribers.
Spam complaints naming Florida codes
FTC Do Not Call complaints where the caller ID shown was a Florida number, 28 Sep – 30 Oct 2026 (33 days). Caller IDs on spam calls are routinely faked, so these are complaints about the code, not calls proven to come from it.
| Code | Complaints | National rank |
|---|---|---|
| 813 | 1,926 | #3 of 422 |
| 321 | 1,360 | #11 of 422 |
| 904 | 1,231 | #19 of 422 |
| 561 | 1,120 | #27 of 422 |

Frequently asked about Florida area codes
How many area codes does Florida have?
23 in service. They are 239, 305, 321, 324, 352, 386, 407, 448, 561, 645, 656, 689, 727, 728, 754, 772, 786, 813, 850, 863, 904, 941 and 954.
What is the oldest area code in Florida?
305, in service since 1947. Every later code in the state was split off from or overlaid on an existing one.
What is the newest area code in Florida?
324, from 2024, overlaying 904.
Is Florida running out of numbers?
407, 561, 786, 850, 305, 904, 813 and 954 are at or past 95% of capacity, but NANPA has not opened relief planning for them, so no new code is announced.
What time zone is Florida in?
It spans 2: Eastern and Central. 448 and 850 cover more than one zone within a single area code, so the code alone does not tell you the time.
Which Florida area code gets the most spam complaints?
813 – 1,926 FTC complaints in the 33 days to 30 October 2026, 3rd of 422 codes nationally. Those are complaints about the caller ID shown, and spam callers routinely fake a local-looking number, so this says the code is imitated often, not that the calls come from there.
Which carrier holds the most Florida numbers?
AT&T, with 27.3% of the 11,207 blocks assigned across Florida, ahead of T-Mobile at 15.5%. This is allocation of blocks by the numbering administrator, not a count of subscribers – people keep their numbers when they switch carriers.
