Austin's Communications & Technology Management Department is pleased to provide this zip code dataset for general use, designed to support a variety of research and analysis needs. Please note that while we facilitate access to this data, the dataset is owned and produced by the United States Postal Service (USPS). Users are encouraged to acknowledge USPS as the source when utilizing this dataset in their work.

U.S. ZIP Code Areas (Five-Digit) represents five-digit ZIP Code areas used by the U.S. Postal Service to deliver mail more effectively. The first digit of a five-digit ZIP Code divides the United States into 10 large groups of states numbered from 0 in the Northeast to 9 in the far West. Within these areas, each state is divided into an average of 10 smaller geographical areas, identified by the second and third digits. These digits, in conjunction with the first digit, represent a sectional center facility or a mail processing facility area. The fourth and fifth digits identify a post office, station, branch or local delivery area.

The 2019 cartographic boundary shapefiles are simplified representations of selected geographic areas from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). These boundary files are specifically designed for small-scale thematic mapping. When possible, generalization is performed with the intent to maintain the hierarchical relationships among geographies and to maintain the alignment of geographies within a file set for a given year. Geographic areas may not align with the same areas from another year. Some geographies are available as nation-based files while others are available only as state-based files. ZIP Code Tabulation Areas (ZCTAs) are approximate area representations of U.S. Postal Service (USPS) ZIP Code service areas that the Census Bureau creates to present statistical data for each decennial census. The Census Bureau delineates ZCTA boundaries for the United States, Puerto Rico, American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the U.S. Virgin Islands once each decade following the decennial census. Data users should not use ZCTAs to identify the official USPS ZIP Code for mail delivery. The USPS makes periodic changes to ZIP Codes to support more efficient mail delivery. The Census Bureau uses tabulation blocks as the basis for defining each ZCTA. Tabulation blocks are assigned to a ZCTA based on the most frequently occurring ZIP Code for the addresses contained within that block. The most frequently occurring ZIP Code also becomes the five-digit numeric code of the ZCTA. These codes may contain leading zeros. Blocks that do not contain addresses but are surrounded by a single ZCTA (enclaves) are assigned to the surrounding ZCTA. Because the Census Bureau only uses the most frequently occurring ZIP Code to assign blocks, a ZCTA may not exist for every USPS ZIP Code. Some ZIP Codes may not have a matching ZCTA because too few addresses were associated with the specific ZIP Code or the ZIP Code was not the most frequently occurring ZIP Code within any of the blocks where it exists. The generalized ZCTA boundaries in this file are based on those delineated following the 2010 Census.

The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation.

This layer shows the boundaries for the Zip Codes in and around the City of Pearland.

Only the five postal zip codes contained in Laredo, TX are included in this dataset. The zip code boundaries are updated annually to reflect current corporate limit boundaries.

A number that identifies each postal delivery area in the city.

Vector polygon map data of city limits from Houston, Texas containing 731 features.

City limits GIS (Geographic Information System) data provides valuable information about the boundaries of a city, which is crucial for various planning and decision-making processes. Urban planners and government officials use this data to understand the extent of their jurisdiction and to make informed decisions regarding zoning, land use, and infrastructure development within the city limits.

By overlaying city limits GIS data with other layers such as population density, land parcels, and environmental features, planners can analyze spatial patterns and identify areas for growth, conservation, or redevelopment. This data also aids in emergency management by defining the areas of responsibility for different emergency services, helping to streamline response efforts during crises..

This city limits data is available for viewing and sharing as a map in a Koordinates map viewer. This data is also available for export to DWG for CAD, PDF, KML, CSV, and GIS data formats, including Shapefile, MapInfo, and Geodatabase.

78744 Zip Code Feature Layer This feature layer represents the 78744 zip code boundary within Travis County and is used in this StoryMap to provide geographic context for Austin Public Health (APH) Community Health Worker (CHW) outreach efforts. On June 8, 2024, APH CHW Strike Teams conducted a targeted West Nile Virus (WNV) education campaign in the 78744 zip code, an area with high social vulnerability and environmental factors that may contribute to increased mosquito activity and disease transmission. This outreach aimed to:

Assess community awareness of WNV transmission and prevention strategies Distribute educational materials on mosquito control and personal protection Engage with residents to encourage proactive public health behaviors

Why the 78744 Zip Code? The 78744 zip code was identified as a priority area for WNV education due to:

Social Vulnerability Index (SVI) Considerations – Populations with higher vulnerability may have limited access to health resources or face greater risks from vector-borne diseases. Environmental Risk Factors – Standing water, dense vegetation, and urban drainage patterns that may support higher mosquito populations. Historical Public Health Needs – Previous outreach efforts have highlighted the importance of continued engagement in this area.

Feature Layer Use This feature layer helps visualize the geographic scope of the CHW outreach efforts and supports public health decision-making by aligning intervention strategies with spatial data and community needs. Future applications of this layer may include:

Mapping mosquito surveillance data and environmental risk factors Overlaying additional public health data for targeted outreach Informing response strategies for future vector-borne disease outbreaks

By incorporating geographic data into public health initiatives, Austin Public Health can ensure a more data-driven, equitable, and effective approach to disease prevention and community engagement.
