Amazon.com vs Amazon.ca Affiliate Links: What Creators Need to Know
Two separate programs, two separate signups, two separate tags — here's what that actually means if your audience spans both countries.
They're genuinely separate programs
Amazon.com Associates and Amazon.ca Associates are not the same program with a regional setting — they're two entirely separate programs, each with their own signup portal, their own approval process, and their own tracking ID. A US tag earns nothing on an amazon.ca sale, and the reverse is equally true.
Registering for both
Amazon.ca Associates has its own dedicated signup (separate from the US Associates Central), and approval is independent — being approved in the US program doesn't automatically approve you in Canada, or vice versa.
Tracking ID format
Both programs commonly use a similar ID format (a -20 style suffix is standard convention in both), but the IDs themselves are entirely distinct per marketplace — matching formats doesn't mean matching accounts or interchangeable tags.
What this means for a mixed US/Canadian audience
If your content reaches both US and Canadian viewers in meaningful numbers, a single .com-only link leaves Canadian sales either uncredited (if the visitor buys through amazon.ca independently) or facing a mismatched checkout experience. The fix is the same pattern covered throughout this cluster: register in both programs, then route each visitor to the matching marketplace and tag automatically, rather than picking one country to serve well at the expense of the other.
Beyond just these two
The same exact logic extends to every other marketplace — amazon.co.uk, amazon.de, and the rest are all equally separate programs. US vs. Canada is simply the most common pairing for North American creators to hit first. See creating Amazon affiliate links for multiple countries for the broader version of this.
