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With our data, you avoid the risks of outdated boundaries and ensure accurate reporting, compliance, and operational efficiency.

International Availability

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.

Canadian Postal Code Details

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:

Postal Code Boundary Files (Canada/General)
ZIP Code Polygons (United States)
FSALDU Shapes or Points (Canada – 6-digit level)
Postal Regions / Zones (General/Enterprise)
Postcode Boundaries (United Kingdom, Australia, New Zealand)
PLZ-Gebiete / PLZ-Polygone (Germany – Postleitzahl, e.g., PLZ 10115)
Codes Postaux Polygones (France – Code Postal)
Codici di Avviamento Postale (CAP) Poligoni (Italy)
Código Postal Polígonos (Spain, Mexico, Argentina, Latin America)
CEP Polígonos (Brazil – Código de Endereçamento Postal)
邮政编码边界 (China – Youzheng Bianma Bianjie)
Pin Code Boundaries (India)
Postnummeromriss (Norway – Postnummer)
Postnummergränser (Sweden)
Postcodegrenzen (Netherlands – Postcode)
Postnumregrænser (Denmark)
Código Postal por Área (Portugal)

No matter the terminology, we deliver precise, up-to-date boundaries tailored to your business or analytics needs.

🇨🇦 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.

Call to Discuss

🇨🇦 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.

🇨🇦 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.

🇨🇦 FSAL Polygons and Points (Canada)

The 4-digit FSAL file represents the first four characters of the Canadian Postal Codes. This database is useful for more of a granular analysis than the FSA boundaries do. This database is ideal for generating customer territories and more generalized sales/service territories.

🇺🇸 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.

🇲🇽 Postal Codes Polygons and Points (Mexico)

Postal codes in Mexico are issued by the Correos de México. There are over 67,000 5-digit postal codes in this database which are identified by the first 2 digits which represent the state, and the last 3 digits represent the local area.

🇬🇧 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.

Note: Postal code polygons are different than latitude-longitude data points. For latitude and longitude coordinates and adding X/Y (GPS) location, please visit our Geocoding page.

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.
