Hello there and thank you for your first post here in the New Seller Community.

The above link provides you with all of the information you are looking for. Shoutout to @Seller_AXC06kcsKI1qGfor the support!

I wanted to just share a few additional resources below:

Here is a 2 minute overview of the North America Unified Account for your review.

Additionally, this page has a lot of great resources including FAQ's on the account. Two of which are the below:

How do I create listings on Amazon.com, Amazon.ca, and Amazon.com.mx stores?

If you register on either Amazon.com, Amazon.ca, or Amazon.com.mx, you have the option to list eligible products across all three stores. To switch stores, select www.amazon.com, www.amazon.ca, or www.amazon.com.mx in the store drop-down list at the top right of your seller account.

What fees will I pay if I sell something using my Unified Account?

For all per-item transaction fees, you will pay the fees applicable to the store in which the item was sold. Your monthly Professional selling plan subscription fee will be allocated to each North American store in which you have active listings on your monthly billing day, and will be limited to USD 39.99 or its equivalent in total. For more information about Professional selling plan fees, go to Selling on Amazon Fee Schedule.

Hope these help!
