在任一商城创建销售账户
要在其他地区进行销售，首先需要在该地区的商城中创建销售账户。完成注册后，您的北美销售账户将与新地区的销售账户关联在一起。
每个地区可以关联一个销售账户。如果您在一个地区的多个商城内均拥有账户，请选择一个账户进行关联。
以下是操作方法：
1. 访问卖家平台中的【全球销售】页面。您可以在【库存】选项卡下选择此选项。
2. 选择您希望关联的地区。
3. 选择用于创建新销售账户的选项。
4. 点击【立即注册】。对于欧盟地区，系统会将您引导至 Amazon.co.uk 商城进行销售账户注册。对于日本，系统会将您引导至 Amazon.co.jp 商城进行销售账户注册。请注意：系统可能会根据您之前输入的信息自动将您的业务和联系信息填入各注册字段。您也可以在这些字段中输入新信息。
5.完成注册后，您的账户将实现自动关联。
返回【全球销售】页面后，您将看到一条消息，指出您的账户已关联。
账户关联后，使用“扩展国际销售”工具跨地区创建商品信息就会变得更为轻松。
单点登录
如果您拥有跨区域的账户，请通过单点登录和浏览器使用单点登录 (SSO) 访问您的所有商城。SSO 允许您使用任意一组账户凭证访问您的任何账户。然后您可以使用商城切换器在您的商城之间来回切换。
如果您已经关联账户，则说明单点登录已生效。如果尚未关联请访问联合账户然后按照此处说明操作。
注意： 如果您在“全球开店”页面上没有看到区域或商城，则说明该 SSO 还不可用。

Create a Selling Account in any Markeplace
The first step to selling in another region is to create a selling account in a marketplace in that region. After you complete registration, your North America selling account will be linked to your selling account in the new region.
You can link one selling account per region. If you have accounts in multiple marketplaces in a region, choose one account to link.
Here's how to start:
1. Visit the Sell Globally page in Seller Central.
You can select this under the Inventory tab.
2. Select the region to which you would like to link.
3. Select the option to create a new selling account.
4. Click Register now. For the European Union, you will be redirected to register for a selling account on the Amazon.co.uk marketplace. For Japan, you will be redirected to register for a selling account on the Amazon.co.jp marketplace. Please note: Your business and contact information may be populated automatically in registration fields based on your previously entered information. You can enter new information in these fields, as well.
5. After you have completed registration, your accounts will be automatically linked.
When you return to the Sell Globally page, you will see a message stating that your accounts are linked.
After your accounts are linked, the Expand Offers Internationally tool makes it easier to create listings across regions.
ingle sign-on
If you have cross-regional accounts, use single sign-on (SSO) to reach all of your marketplaces from a single sign-in and browser. SSO lets you access any of your accounts with any set of account credentials. Then you can use the marketplace switcher to alternate between your marketplaces.
Single sign-on is already in effect if you have linked your accounts. If they are not yet linked, visit Linking accounts and follow the instructions there.
Note: If you don’t see a region or marketplace on the Sell Globally page, SSO is not yet available for it.
