Hello. Your serial number is on the bottom of your camera. If your product was made for use outside of the United States, it may not be allowed to be registered in our system. This is called Gray Market. If you try registering using the number from the bottom of your camera and have issues, we recommend reaching out to our customer support agents for help. They're at 800-385-2155.

One word of caution here. Amazon itself is a Canon USA authorized dealer. If it was from Amazon itself and not one of Amazon's marketplace retailers you are golden. The problem is some of the marketplace retailers are not Canon USA dealers. If it was from a non-Canon USA retailer I would return it if possible. Today!

Usually you can spot these because some offer huge packages of pure junk along with the camera. And, a somewhat lower price is a dead give away, too. Usually it is difficult to tell unless you read all the 'fine' print. Most but not all of these sources have an "in-house" warranty shop. Not a Canon service center for sure.

EOS 1DX and 1D Mk IV and less lenses then before!
