Overview
Understanding ZIP code 21543
ZIP code 21543 is assigned to Midlothian, MD, and falls within Allegany 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 325 people live inside it.
At 132 residents per square mile spread over 2.465 square miles, 21543 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.
Living here
What life in Midlothian looks like
Housing in 21543 costs close to the national median. A typical home is valued at $186,000 against a US median of $207,500, and median gross rent runs $775 a month. Ownership dominates: 90.3% 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 97.3% of housing units here. The median construction year is 1971, making the housing here from the later twentieth century.
The population skews broadly in line with the national age profile, with a median age of 42.8 against 42 nationally. Households average just 1.66 people, and 44.4% consist of one person living alone — a signature of areas with a lot of studio and one-bedroom stock.
Getting to work takes 34.7 minutes on average one way. The dominant mode is drove alone at 90.4% of workers.
Where to stay
Where to stay in Midlothian, MD
21543 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 $775 a month — and accommodation prices in the area tend to be correspondingly reasonable. For reference, Philadelphia, PA is about 202.6 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.

Practical uses
What ZIP code 21543 is used for
Beyond addressing mail, 21543 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, 21543 offers a compact profile of Midlothian: 325 residents, 8.0% of adults holding a bachelor's degree or higher, and an unemployment rate of 23.6%. 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. 21543 may cover parts of several distinct areas, and a single neighbourhood in Midlothian 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.
