Postal Code Polygons

Postal Code Polygons


Coverage: Worldwide


Postal Code Polygons are shapes that represent the geographical extent of postal codes. By overlaying these polygons on a map, it is possible to analyze and understand patterns and relationships in data that have a geographical component and then analyze data such as population density, demographics, and consumer behavior within those areas.

Our Postal Code Polygons service is a versatile solution that caters to various industry segments. We provide regularly updated and accurate polygon data for postal codes, ensuring that you have access to the most current information available. Postal Code Polygons are essential for businesses that rely on location-based data for their operations. With our regularly updated data, you can stay up to date with changes in postal code boundaries. This ensures that your business remains efficient and compliant, avoiding errors and inaccuracies that can arise from outdated information.

6-digit postal code polygons for Canada are also known as FSALDU Polygons and Points.

Canadian Postal Code Boundary files also have alternate names. We’ve outlined the most common ones below. These terms are often interchangeable and typically refer to the same thing, so no matter the name, we can offer it to you.
Our postal code boundaries are available internationally, and we can supply any number of files whether it’s a Canadian postal code or a postal/zip code from another country.

FSALDU Polygons and Points (Canada) – Canada Postal Codes Polyons


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.


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 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.


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.
