What Is It

What Are Postal Code Polygons?

Geospatial Boundaries for Accurate Regional Analysis

Postal Code Polygons are geographic shapes that define the real-world extent of postal or ZIP codes. When overlaid on a map, these polygons allow you to visualize, analyze, and extract insights tied to specific postal areas — enabling smarter decisions in everything from customer targeting to network planning.

By linking location-based data (like addresses, sales, or infrastructure) to postal regions, organizations can:

  • Analyze population density and demographics
  • Visualize customer distribution and service areas
  • Perform territory planning, route optimization, and market segmentation
  • Built for Real-World Business Needs

Aeroview’s Postal Code Polygons are designed to meet the needs of enterprise-grade platforms. We offer:

  • Regular updates to reflect postal code splits, reassignments, and new development areas
  • Multiple formats and delivery options (API, GeoJSON, Shapefile, CSV, WMTS)
  • National and international coverage — including Canada, the U.S., and other global regions

With our data, you avoid the risks of outdated boundaries and ensure accurate reporting, compliance, and operational efficiency.

🇨🇦 FSALDU Polygons and Points – Canada Postal Codes Polygons

The FSALDU database contains polygon and point representations showing the locations of Canadian Postal Codes.

There are over 890,000 unique postal codes in this file that represent both Forward Sortation Areas (FSA) and Local Delivery Units (LDU). The first character in the Forward Sortation Areas are defined geographic areas and are also known as “postal districts”.

These districts often cover an entire province, except for Ontario and Quebec where there are multiple districts due to population. The second character (which is a digit) within the Forward Sortation Area indicates whether the geographic area is urban or rural.

Any FSA with a “0” in the middle of the 3-digit code indicates a rural location. The third character in an FSA represents an urban area, an entire town or city, or a portion of a major metropolitan area.

🇨🇦 FSA Polygons and Points (Canada)

The FSA (or Forward Sortation Area) database contains all postal districts within Canada. There are over 1,600 Forward Sortation Areas in this database within Canada and represent the geographic area of all 6-digit (FSALDU) postal codes within that FSA.
WORLDWIDE POSTAL CODES POLYGONS

🇨🇦 FSALD Polygons and Points (Canada)

The 5-digit FSALD location represents a more general view of postal codes than the FSALDU polygons do. This database is ideal for generating sales and service territories among other forms of analysis.

🇺🇸 Zip Code Polygons and Points (United States)

Zip codes, or Zone Improvement Areas, are created by the United States Postal Service and contain over 41,000 active zip codes in this database for the United States.

The first digit in the Zip Code represents the State or group of States within the US. The second and third digit represents a larger geographic region (including part of a city or town) while the fourth and fifth digit represents a more specific area or location inside that region.

🇬🇧 Postcode Polygons and Points (UK)

Postcodes in the UK are alphanumeric in nature and represent a delivery area containing a grouping of addresses or a single delivery unit.

They can range from six to eight characters and are made up of an outward code and an inward code. The outward code contains the postcode area and the postcode district while the inward code includes the postcode sector and postcode unit. This file contains over 1.7M postcodes for the UK.

Frequently Asked Questions

What do Postal Code Polygons represent?

Postal Code Polygons are geographic boundaries that define the spatial extent of postal delivery areas. They represent the geographical limits assigned to each postal code by postal authorities, allowing you to visualize and analyze data within specific postal code regions rather than using simple point coordinates.

Postal Code Polygons provide notional representations of postal delivery areas with varying accuracy depending on the postal system. The boundaries are derived from postal authority source data and are typically accurate to within 50-100 meters in urban areas. In Canada, 6-digit FSALDU polygons represent the most precise level of postal code boundaries available, more granular than FSA (3-digit) or FSAL (4-digit) boundaries.

No. High-quality postal code polygon datasets are designed without gaps or overlaps to ensure continuous geographic coverage, even in areas where gaps may exist in reality such as remote mountainous regions. This design approach ensures seamless spatial analysis without unmapped territories.

Postal Code Polygons define entire geographic areas for postal delivery zones, while centroid points represent a single coordinate location (typically the center) within each postal code area. For mapping and spatial analysis of regional patterns, polygons are superior; for geocoding and point-based analysis, centroids are more appropriate.

Aeroview provides worldwide coverage of postal code polygons, including complete datasets for many countries of the world, such as Canada (890,000+ unique postal codes), the United States (41,000+ ZIP codes), Mexico (67,000+ postal codes), the United Kingdom (1.7M+ postcodes), and others.

Yes. The dataset includes both urban and rural postal code areas. For example, in Canada’s postal code system, the second digit being “0” in the FSA code indicates a rural region, while all other digits indicate urban areas. Rural addresses are essential for complete geographic coverage and emergency services.

Aeroview provides regularly updated postal code polygon data to ensure currency. Postal code changes occur continuously due to urban expansion, new developments, and administrative reorganization – on average approximately 2,085 ZIP codes change annually in the US alone. Quality postal code providers update weekly, drawing from multiple official sources.

Postal code boundaries change for several reasons: urban development and new residential/commercial construction, population density shifts requiring new postal codes, administrative boundary reorganization, improved logistics efficiency, and corrections to outdated codes. For example, rapid population growth in regions like Arizona and Florida has led to creation of new ZIP codes and division of existing ones.

Aeroview offers multiple GIS-compatible formats including Shapefile, File Geodatabase, CSV, GeoJSON, KML, and REST services. These formats ensure compatibility with major GIS platforms like ArcGIS and QGIS, as well as web mapping applications and business intelligence tools.

Each polygon record includes the postal code identifier, geographic boundaries (coordinates), centroid location (latitude/longitude), polygon area and perimeter measurements, municipality and province/territory, administrative hierarchy levels (for Canada these would be FSA, FSAL, FSALD, or FSALDU), and metadata such as urban/rural designation.

Postal Code Polygons are designed for seamless integration with standard GIS software and mapping platforms. The data is provided in industry-standard formats with WGS84 datum (SRID 4326) coordinates, compatible with web mapping libraries (Leaflet, Mapbox), ArcGIS, QGIS, and enterprise GIS workflows.

Postal Code Polygons are widely used for territory planning and management, sales and delivery zone definition, market analysis and consumer behavior mapping, site location analysis for retail and real estate, risk aggregation and environmental assessment, logistics optimization and route planning, demographic profiling, and targeted marketing campaigns. Accurate boundaries improve territory accuracy five-fold compared to point-based methods.
