Aeroview’s Postal Code Polygons provide accurate, up-to-date spatial boundaries for postal codes across Canada, the United States, and international markets. Our data is built for enterprise-scale mapping, location analytics, and system integration – making it ideal for platforms that demand both precision and performance.
Access complete postal code boundaries for Canada, the United States, and key international regions — all in one unified, ready-to-integrate dataset.
Each boundary is meticulously constructed and validated using official postal data, municipal inputs, and parcel-level overlays for industry-leading accuracy.
Available via API, WMTS tile service, or as downloadable GeoJSON, Shapefile, and CSV — ensuring easy compatibility with your GIS or analytics environment.
Keep your systems aligned with the latest changes. Our regular update cycle reflects new postal codes, reassignments, urban expansions, and boundary modifications.
Transparent, scalable licensing designed for internal use, commercial applications, and SaaS platforms — with no restrictive terms or hidden fees.
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:
Aeroview’s Postal Code Polygons are designed to meet the needs of enterprise-grade platforms. We offer:
With our data, you avoid the risks of outdated boundaries and ensure accurate reporting, compliance, and operational efficiency.
While our postal code polygon data began with nationwide Canadian coverage, we now support postal and ZIP code boundaries in multiple countries. Whether you need Canadian FSALDUs, U.S. ZIP code boundaries, or datasets from Europe, Asia, or South America — Aeroview provides reliable global postal boundary data at scale.
In Canada, our polygons include 6-digit postal codes known as FSA-LDU (Forward Sortation Area – Local Delivery Unit). These are also commonly referred to as:
No matter the terminology, we deliver precise, up-to-date boundaries tailored to your business or analytics needs.
Our data products are available in various formats including Postal Code Shapefiles, Zip Code Shapefiles, Zip Code KML, and Postal Code KML.
Note: Statistics Canada does not offer Canadian Postal Code data to the 6-digit (FSALDU) level.

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.
Licensing terms vary depending on the specific agreement. Commercial use rights, redistribution permissions, and data deployment scope depend on your license type. Common restrictions may include limitations on sublicensing to third parties and repackaging of raw data, though specific terms vary by provider.
