Louisiana Address Generator

Louisiana's county-level divisions are parishes — the Census Bureau's reference manual lists it as one of the two standing exceptions, alongside Alaska's boroughs. There are 64 of them, and our own postal dataset agrees: the county field across Louisiana's postal codes resolves to exactly 64 distinct names. The term is not a nickname or a historical curiosity; it is the legal name of the jurisdiction, and state agencies, courts and tax authorities all use it.

For software the fix is smaller than people expect, because a mailing address never carries a county line in the first place. The Postal Service's standards end an address with city, state and ZIP. Where the parish shows up is everywhere else: the label on a form, a dropdown of jurisdictions, a sales-tax table, a report grouped by county. A Louisiana user who is asked for their "county" will usually work out what you mean and still register that you did not know.

The tax case is the one that has teeth. Louisiana's local sales taxes are administered parish by parish, so a jurisdiction table keyed on county names has to hold parish names for this state, and code that derives a jurisdiction by appending the word "County" to a name produces something that does not exist. That is a good fixture: it fails loudly in Louisiana and silently almost everywhere else.

Two more Louisiana specifics are worth having in a fixture. The state's 719 postal codes sit under only 13 three-digit prefixes, so its postal geography is far more concentrated than its land area suggests — 700 and 701 alone cover the New Orleans region. And Orleans Parish and the City of New Orleans are the same territory: a record can name the city and the parish and still describe one boundary, which is the opposite of the Virginia case, where a city and a county with the same name are seventy miles apart. Any deduplication that assumes city and county are always distinct levels gets both states wrong, in opposite directions.

Random Louisiana phone numbers here use the state's real area codes — 504, 225, 318 and 337 — with the 555-01XX line range the North American Numbering Plan reserves for fiction, so a number such as (504) 555-0154 passes format and area-code checks yet can never ring anyone. Every profile this page generates carries one that agrees with its Louisiana address; for a batch of numbers on their own, the random Louisiana phone number generator draws from the same range with any US area code.

Three examples in the reserved range: (504) 555-0154, (225) 555-0185, (318) 555-0173. Area codes are geographic, so a Louisiana address paired with a non-LA area code fails the consistency check that fraud systems and good validators run — which is why this page pins both to Louisiana. 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.
