Your AWS Account ID and Its Alias

About Account Aliases
If you want the URL for your sign-in page to contain your company name (or other friendly identifier) instead of your AWS account ID, you can create an alias for your AWS account ID. This section provides information about AWS account aliases and lists the API actions you use to create an alias.
Your sign-in page URL has the following format, by default.
If you create an AWS account alias for your AWS account ID, your sign-in page URL will look like the following example.
The original URL containing your AWS account ID remains active and can be used after you create your AWS account alias.
To create a bookmark for your account sign-in page in your web browser, you should manually type the sign-in URL in the bookmark entry. Don't use your web browser's "bookmark this page" feature.
Creating, Deleting, and Listing an AWS Account Alias
You can use the AWS Management Console, the IAM API, or the command line interface to create or delete your AWS account alias.
Your AWS account can have only one alias. If you create a new alias for your AWS account, the new alias overwrites the old alias, and the URL containing the old alias stops working.
