Overview

Understanding ZIP code 12457

ZIP code 12457 is assigned to Mount Tremper, NY, and falls within Ulster 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 1,171 people live inside it.

At 102 residents per square mile spread over 11.442 square miles, 12457 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 $73,949 puts 12457 near the middle of the pack, ahead of 57% 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 Mount Tremper looks like

Housing in 12457 costs well above the national median. A typical home is valued at $386,100 against a US median of $207,500, and median gross rent runs $1,500 a month. Ownership dominates: 70.1% of occupied homes are owner-occupied, which usually signals an established residential area with relatively low turnover.

The building stock is dominated by detached single-family houses, which account for 83.9% of housing units here. The median construction year is 1960, making the housing here mid-century.

The population skews broadly in line with the national age profile, with a median age of 39.6 against 42 nationally. The average household holds 2.3 people, and 55.0% are family households.

Getting to work takes 23.6 minutes on average one way. The dominant mode is drove alone at 63.4% of workers, while 20.0% work from home. Commute patterns are one of the better proxies for how a place actually functions day to day.

Where to stay

Where to stay in Mount Tremper, NY

12457 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.

Median rent in 12457 is $1,500 a month, which sits in the middle of the national range; accommodation pricing locally tends to be similarly mid-market. For reference, New York, NY is about 92.5 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 12457 is used for

Beyond addressing mail, 12457 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, 12457 offers a compact profile of Mount Tremper: 1,171 residents, a median household income of $73,949, 45.7% of adults holding a bachelor's degree or higher, and an unemployment rate of 2.4%. 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. 12457 may cover parts of several distinct areas, and a single neighbourhood in Mount Tremper 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.

Median gross rent in 12457 is $1,500 a month, according to the American Community Survey. Gross rent includes contract rent plus the estimated cost of utilities and fuels, so it is closer to what a tenant actually pays than a headline rent figure. Of 509 occupied homes here, 152 are rented.

Does 12457 cover more than one city or county?
This page lists Mount Tremper as the primary place and Ulster 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 12457 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.
