Send any Canadian address and get back its FSA and full postal code, along with the city, province, neighbourhood and coordinates. Then use the FSA to pull its boundary, demographics and building permits, all from one API.
Neighbourly treats the postal code as part of a connected address record, so finding the code is the start of the lookup, not the end.
Send a raw address, abbreviations and all, to /v1/address. The response returns the FSA and full postal code as separate fields, along with the normalized address and coordinates.
Retrieve Forward Sortation Area polygons from /v1/fsa/{{fsa}} for postal area maps, demographic choropleths and FSA-level market analysis.
Use the FSA as a key to query census-derived demographics and building permits, so a postal area connects to the rest of the Neighbourly platform without a second vendor.
Every Canadian postal code follows the pattern A1A 1A1. The first three characters are the Forward Sortation Area, which covers a geographic delivery area. The last three are the Local Delivery Unit, which narrows it to something as small as a city block or a single building.
In Neighbourly responses, fsa holds the first three characters and ldu holds the full six-character code. The letters D, F, I, O, Q and U are never used, and W and Z never appear first.
The first letter of a Canadian postal code identifies its postal district. Most match a province or territory, while Quebec and Ontario are split into several.
Messy input goes in and clean, separate fields come back, ready to store, filter or join with the rest of your data.

From a single form field to an entire customer file, postal codes connect records to places.
Pair the typeahead endpoint with address lookup so customers pick an address and the postal code, city and province come with it, cutting typing errors at the source.
Resolve each listing address to its FSA, then attach census-derived demographics and nearby permit activity to the property page.
Assign policies or loans to Forward Sortation Areas, then compare portfolios and markets using one consistent set of FSA boundaries and demographics.
Run existing addresses through the API to add missing postal codes and normalized fields, so customer and property records join cleanly.
Common questions about this data and how to use it.
Send the address to the /v1/address endpoint. The response returns the FSA and full postal code as separate fields, along with the normalized address, city, province, neighbourhood and coordinates.
The FSA, or Forward Sortation Area, is the first three characters of a postal code and covers a geographic delivery area. The LDU, or Local Delivery Unit, is the last three characters and narrows it to something as small as a city block or building. In Neighbourly responses, the ldu field holds the full six-character code.
At the FSA level you can retrieve the boundary polygon, census-derived demographics and building permits. FSA boundaries come from /v1/fsa/{fsa}, and demographics from /v1/demographics/find?fsa=.
Not on its own. The tool checks the format and region, then shows area data for the code's FSA. A correctly formed full postal code may still not be in use.
Six characters in the pattern A1A 1A1, alternating letters and digits. The letters D, F, I, O, Q and U are never used, and W and Z never appear as the first letter.
It identifies the postal district. Most letters match a province or territory, while Quebec and Ontario are split across several: G, H and J for Quebec, and K, L, M, N and P for Ontario.
Address and postal code resolution covers all Canadian provinces and territories, and every FSA in Canada has a census-derived demographic profile.
