Overview

Understanding ZIP code 21790

ZIP code 21790 is assigned to Tuscarora, MD, and falls within Frederick 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 38 people live inside it.

At 8 residents per square mile spread over 4.788 square miles, 21790 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 Tuscarora looks like

The building stock is dominated by larger apartment buildings of twenty units or more, which account for 100.0% of housing units here. At 0.0%, vacancy is low — housing here is tightly held.

The population skews notably young, with a median age of 2.9 against 42 nationally. Households are relatively large at 4.75 people on average, with 100.0% classified as family households.

Getting to work takes 37.0 minutes on average one way. The dominant mode is drove alone at 100.0% of workers.

Where to stay

Where to stay in Tuscarora, MD

21790 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.

For reference, Philadelphia, PA is about 133.2 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 21790 is used for

Beyond addressing mail, 21790 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, 21790 offers a compact profile of Tuscarora: 38 residents, 0.0% 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. 21790 may cover parts of several distinct areas, and a single neighbourhood in Tuscarora 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 21790 cover more than one city or county?
This page lists Tuscarora as the primary place and Frederick 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 21790 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.
