Overview

Understanding ZIP code 23356

ZIP code 23356 is assigned to Greenbackville, VA, and falls within Accomack 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 1,738 people live inside it.

At 489 residents per square mile spread over 3.553 square miles, 23356 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.

Household earnings run above the national median. At $98,934, 23356 sits comfortably in the upper half, ahead of 82% 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 Greenbackville looks like

Housing in 23356 costs close to the national median. A typical home is valued at $227,400 against a US median of $207,500. Ownership dominates: 94.5% 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 99.2% of housing units here. The median construction year is 2004, making the housing here relatively modern. The vacancy rate of 44.2% is high, which in many places reflects seasonal or second-home use rather than abandonment.

The population skews considerably older than the national median, with a median age of 60.8 against 42 nationally. The average household holds 2.19 people, and 78.1% are family households.

Getting to work takes 29.6 minutes on average one way. The dominant mode is drove alone at 71.5% of workers, while 22.8% 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 Greenbackville, VA

Greenbackville is a smaller community, so options inside 23356 may be limited to a handful of independent inns, motels or bed-and-breakfast properties. Travellers often widen the search to the surrounding area, where the choice is greater and prices are usually competitive.

For reference, Philadelphia, PA is about 134.7 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 23356 is used for

Beyond addressing mail, 23356 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, 23356 offers a compact profile of Greenbackville: 1,738 residents, a median household income of $98,934, 38.6% of adults holding a bachelor's degree or higher, and an unemployment rate of 9.7%. 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. 23356 may cover parts of several distinct areas, and a single neighbourhood in Greenbackville 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.

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.
