Overview
Understanding ZIP code 70083
ZIP code 70083 is assigned to Port Sulphur, LA, and falls within Plaquemines Parish. Like every US postal code, it began as a mail-routing device rather than a geographic boundary — the US Postal Service groups delivery routes under a single code so carriers and sorting equipment can process mail efficiently. Today it also serves as a practical shorthand for the area itself: roughly 2,456 people live inside it.
At 19 residents per square mile spread over 129.185 square miles, 70083 reads as a rural area. It is a sparsely populated postal code, and density shapes almost everything else on this page — how people get to work, whether they own or rent, and what housing costs.
Household earnings track close to the national picture. The median of $66,250 puts 70083 near the middle of the pack, ahead of 44% of them. The US median for comparison is $70,109. Bear in mind that median income describes the midpoint household, not the average — it is not pulled upward by a handful of very high earners the way a mean would be.

Where to stay
Where to stay in Port Sulphur, LA
70083 covers a rural area, and accommodation within the postal code itself is likely to be sparse — perhaps a country inn, a lodge or a vacation rental rather than a conventional hotel. Widening the search radius is usually the practical approach, and it also opens up more availability at short notice.
For reference, Houston, TX is about 332.3 miles away in a straight line, which is worth factoring in if you are comparing a stay here against one closer to the city centre.

Practical uses
What ZIP code 70083 is used for
Beyond addressing mail, 70083 does a lot of quiet administrative work. Retailers use it to calculate shipping and sales tax at checkout. Insurers use it to set premiums, since risk profiles vary geographically. Employers and marketers use it to define service areas. Government agencies use it to route benefits and organise reporting. If you have ever been asked for a postal code by a form that clearly does not intend to send you anything, this is why.
For anyone weighing a move, 70083 offers a compact profile of Port Sulphur: 2,456 residents, a median household income of $66,250, 9.8% of adults holding a bachelor's degree or higher, and an unemployment rate of 7.4%. A handful of figures like these answer more relocation questions than most neighbourhood guides do.
One caution worth repeating: a postal code is not a neighbourhood. 70083 may cover parts of several distinct areas, and a single neighbourhood in Port Sulphur may be split across more than one code. Boundaries also shift as USPS adjusts delivery routes. Treat the figures here as describing a delivery area, which is what they actually measure.
