Overview
Understanding ZIP code 70663
ZIP code 70663 is assigned to Sulphur, LA, and falls within Calcasieu County. 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 29,511 people live inside it.
At 302 residents per square mile spread over 97.776 square miles, 70663 reads as a small-town area. It is a populous 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 run below the national median. At $59,444, 70663 sits in the lower half, ahead of 31% 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.

Practical uses
What ZIP code 70663 is used for
Beyond addressing mail, 70663 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, 70663 offers a compact profile of Sulphur: 29,511 residents, a median household income of $59,444, 17.1% of adults holding a bachelor's degree or higher, and an unemployment rate of 4.5%.

One caution worth repeating: a postal code is not a neighbourhood. 70663 may cover parts of several distinct areas, and a single neighbourhood in 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.
