Area code 561 vs 728
561 and 728 are overlay codes: they cover the same ground in Florida, and a number in one is a local call to the other. 561 is the original, in service since 1996. 728 was added in 2023 because the first was filling up – that is what an overlay is for. Today 561 has 786 of 786 blocks assigned (100.0%) and 728 has 69 of 786 (8.8%), so a new number in the area now almost always comes from 728. In the 33 days to 30 October 2026, 561 drew 1,120 FTC complaints against 59 for 728 – 27th and 383rd of 422 ranked codes. Older codes are spoofed more because they look more established. Neither code is better or safer than the other. They are the same geography, the same carriers and the same dialing rules; the difference is only how long each has existed and how full it is.

Frequently asked
What is the difference between area codes 561 and 728?
None geographically – they overlay the same area, so the difference is age and how many numbers are left.
Do I need to dial the area code between 561 and 728?
Yes. Overlay areas use ten-digit dialing for local calls, including between the two codes. Seven digits reaches a recording.
Will a new number be 561 or 728?
Whichever has blocks left – currently 728, at 8.8% allocated against 100.0% for the other. Carriers draw from the code with free blocks, which is why the newer code spreads over time.
Is 561 or 728 more likely to be a spam call?
On the complaint data, 561 appears more often. But spoofing drives those counts, so this is about which code gets imitated, not which numbers are real.
