Overview

Understanding ZIP code 95604

ZIP code 95604 is assigned to Auburn, CA, and falls within Placer 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 24 people live inside it.

At 480 residents per square mile spread over 0.05 square miles, 95604 reads as a small-town 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.

Where to stay

Where to stay in Auburn, CA

For reference, San Francisco, CA is about 162.3 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 95604 is used for

Beyond addressing mail, 95604 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, 95604 offers a compact profile of Auburn: 24 residents, 100.0% of adults holding a bachelor's degree or higher, and an unemployment rate of 0.0%. 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. 95604 may cover parts of several distinct areas, and a single neighbourhood in Auburn 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.

Does 95604 cover more than one city or county?
This page lists Auburn as the primary place and Placer County as the county.

Can ZIP code 95604 change?
Yes. USPS adjusts ZIP codes as delivery volumes shift — codes are occasionally split, merged, retired or newly created, and boundaries move more often than most people assume.

On accuracy. ACS figures are survey estimates, not counts. The margin of error shown alongside the population figure means the true value has a 90% chance of falling in that range. For small ZIP codes the error can be large relative to the estimate — treat the direction as more reliable than the exact number.
