Overview

Understanding ZIP code 40935

ZIP code 40935 is assigned to Flat Lick, KY, and falls within Knox 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 1,979 people live inside it.

At 32 residents per square mile spread over 61.857 square miles, 40935 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 are well below the national median. At $21,707, 40935 ranks among the lower-income postal codes, ahead of 0% 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.

Living here

What life in Flat Lick looks like

Housing in 40935 costs well below the national median. A typical home is valued at $50,900 against a US median of $207,500, and median gross rent runs $681 a month. The split between owning and renting is fairly even at 65.9% owner-occupied, which tends to indicate a mix of housing types rather than one dominant form.

The building stock is dominated by larger apartment buildings of twenty units or more, which account for 48.4% of housing units here. The median construction year is 1985, making the housing here from the later twentieth century. The vacancy rate of 29.6% is high, which in many places reflects seasonal or second-home use rather than abandonment.

The population skews younger than the country as a whole, with a median age of 35.5 against 42 nationally. The average household holds 2.48 people, and 78.9% are family households.

Getting to work takes 29.2 minutes on average one way. The dominant mode is drove alone at 85.9% of workers.

Where to stay

Where to stay in Flat Lick, KY

40935 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.

Local costs are modest — median rent here is $681 a month — and accommodation prices in the area tend to be correspondingly reasonable. For reference, Atlanta, GA is about 224.6 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.

Availability and pricing change constantly, so the live search below will give you a more accurate picture than any figure we could publish here. It opens results for this area on Booking.com.

Practical uses

What ZIP code 40935 is used for

Beyond addressing mail, 40935 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, 40935 offers a compact profile of Flat Lick: 1,979 residents, a median household income of $21,707, 13.3% of adults holding a bachelor's degree or higher, and an unemployment rate of 29.3%. 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. 40935 may cover parts of several distinct areas, and a single neighbourhood in Flat Lick 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 40935 cover more than one city or county?
This page lists Flat Lick as the primary place and Knox County as the county. ZIP codes follow mail delivery routes rather than municipal or county lines, so a single code can straddle boundaries, and USPS also recognises alternate acceptable city names for many codes. If you need the definitive answer for a specific street address, the USPS ZIP Code Lookup is the authority.
Can ZIP code 40935 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. The Census Bureau's ZCTA definitions, which underpin the demographic figures on this page, are redrawn only once a decade, so the two can drift apart between censuses.

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.
