Maryland ZIP Codes



Timezone(s): All Time Zones found within this State. In the United States, there are 7 standard time zones which are, from west to east: Hawaii-Aleutian, Alaska, Pacific, Mountain, Central, Eastern, Atlantic. Also included in U.S. Territories are Samoa, Guam and Palau. The alignment between ZIP codes and time zones is not perfect. A single time zone can cover multiple ZIP codes, and, conversely, a single ZIP code could theoretically span across multiple time zones, although this is quite rare.Eastern (GMT -05:00)
 
Population: The total Population for Maryland, taken from the 2020 U.S. Census DP1. This population total includes all people residing in Maryland and counts them regardless of citizenship or immigration status. Included are U.S. Citizens, permanent residents, temporary migrants, and undocumented workers. The total population represents people who live in the state, not just those present on the day of the census. State Population is critical in determining political representation, funding allocation, planning and policy-making, and demographic analysis.6,177,224 (More Details)
Male Population: The sum of all males for Maryland from the 2020 U.S. Census DP1. Each respondent self-identified their gender on the survey, as they were asked to indicate their gender assigned at birth. The male population information is important for healthcare planning, policy making, social research, and economic planning and development.2,975,416
Female Population: The sum of all females for Maryland from the 2020 U.S. Census DP1. Each respondent self-identified their gender on the survey, as they were asked to indicate their gender assigned at birth. The female population information is important for healthcare planning, policy making, social research, and economic planning and development.3,201,808
Median Age: The median age of the total population of this state. Median age is not a future prediction, it is the actual number from the 2020 Census. Median age is the middle age of the population. Half the population is older than the average age and half is younger.39
 
ZIP Codes: The total number of ZIP Codes which at least partially fall inside the state of Maryland. Did you know that approximately 23% of ZIP Codes cross county lines? Several even cross State lines. ZIP Codes do not follow other geographic boundaries because they were created exclusively for the expedient delivery of mail.601
Cities: The total number of City names which are associated with ZIP Codes that partially or wholly cross into Maryland. Alongside the official city name, USPS also recognizes certain alternate names for cities or towns that can be used in mailing addresses. These may include towns, villages, abbreviations, names in other languages, or names that have been commonly used historically.429
Counties: The total number of counties associated with ZIP Codes that are at least partially part of Maryland.24
Area Codes: The total number of Area Codes associated with ZIP Codes in Maryland. Area codes are used in the North American Numbering Plan (NANP) to facilitate phone routing. Each area code identifies a specific geographic area (usually part of a state or territory) and allows calls to be routed to the correct area. There are approximately 350 area codes in use in the United States.2
 
Total Area: The approximate amount of area covered by Maryland in square miles. This includes all land and water areas within the legal state boundaries.12,406 square miles
Land Area: Approximate area of land covered by Maryland in square miles. Land area data provided by the Census Bureau are based on geographic boundaries that include the mainland, islands, inland, coastal, Great Lakes, and territorial waters associated with each state. Land area is important in many types of statistical analysis. For example, population density, the number of people per unit of land area, is a commonly used statistic based on this data. Land area measurements are also important for urban planning, environmental studies, and economic analysis. 9,710 square miles
Water Area: The approximate amount of water area covered by Maryland in square miles. Calculations for water area take into account inland bodies of water, coastal regions, Great Lakes, and territorial sea waters. This encompasses features such as lakes, reservoirs, rivers, and coastal water bodies. Water surface data are especially important for environmental and conservation planning, water resource management, transportation, and recreational planning.2,696 square miles
