Canadian Postal Code Database

Canadian Postal Code Database (v1.0)

Data Records: 765,344

Database Fields:

Notes: This database is a few years old and I've had reports of a missing postal code now and then. If you find any, let me know.


We were recently contacted by a representative from Canada Post and asked to take our crowd sourced database offline. It seems that Canada Post believes they own the copyright to all Canadian postal codes. You can read a copy of the letter they sent here.

They also followed up with a phone call and didn't seem to care that the database was crowd sourced. The gentleman I spoke with was very clear that he felt Canada Post owns the copyright on all postal codes.

Personally I feel like never using a postal code when I send mail ever again.

If you have any questions or concerns please feel free to contact him:

I guess we'll let someone else (hopefully with deeper pockets) fight this in court. But for now the database is offline.

Sorry people. If any of you hear about Canada Post losing their case please contact us.
