Florida Address Generator

Florida's ZIP codes run from 320 to 349, and the natural validator to write is a range check. It fails on one specific prefix, and it fails in an interesting direction: 340 sits squarely inside Florida's block and is not Florida at all. It is APO AA — Armed Forces Americas — military mail routed through the state without belonging to it. A range rule files a soldier's mailing address in Florida; a prefix-set rule built from the actual data does not, because Florida's 26 prefixes have four gaps (340, 343, 345 and 348), and 340 is the gap with an owner.

The rest of the state is big-league by volume: 1,473 codes, fifth in the country behind Texas, California, Pennsylvania and New York, spread over 67 counties at about 22 codes each. Miami-Dade is the largest county block at 126 codes, ahead of Hillsborough's 94 and Broward's 89 — and the largest single prefix is Miami's 331, just ahead of West Palm Beach's 334, which makes Florida one of the minority of states where the biggest sorting block really is the biggest metro.

Tax logic is the other reason a Florida fixture earns its place. Florida levies no personal income tax — the state constitution prohibits one — but it does levy sales tax, which is the exact inverse of Oregon and the diagonal opposite of New Hampshire (no sales tax, and no wage income tax either). A payroll test keyed on Florida exercises the zero-income-tax branch while the checkout still computes sales tax, and code that conflates the two taxes gets caught by precisely this pair.

One caution the search traffic makes necessary: a generated Florida address is a format teaching tool, not a residence. The codes here are real prefixes with invented street-level detail, which is what form validation and shipping-rate tests need — and none of it establishes Florida residency for tax, insurance, tuition or any other purpose. Residency is a legal status; an address string is not.

Random Florida phone numbers here use the state's real area codes — 305, 407, 813 and 904 — with the 555-01XX line range the North American Numbering Plan reserves for fiction, so a number such as (305) 555-0106 passes format and area-code checks yet can never ring anyone. Every profile this page generates carries one that agrees with its Florida address; for a batch of numbers on their own, the random Florida phone number generator draws from the same range with any US area code.

Three examples in the reserved range: (305) 555-0106, (407) 555-0176, (813) 555-0172. Area codes are geographic, so a Florida address paired with a non-FL area code fails the consistency check that fraud systems and good validators run — which is why this page pins both to Florida. How area codes are assigned, and why the 555 block exists, are covered in how US area codes work and why fake phone numbers start with 555.
