Using an alias for your Amazon Web Services account ID - Amazon Identity and Access Management
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Using an alias for your Amazon Web Services account ID

Your account ID is a 12-digit number that uniquely identifies your account. By default, IAM users in the account sign in using a web URL that includes the account ID. If they don't have the URL, they can provide the account ID on the Amazon sign-in page when they sign-in.

Your sign-in page URL has the following format, by default.

https://Your_Account_ID.signin.amazonaws.cn/console/

Many people find words to be easier to remember than numbers, so creating an alias for your account ID can help your IAM users sign-in easier.

If you create an Amazon Web Services account alias for your Amazon Web Services account ID, your sign-in page URL looks like the following example.

https://Your_Account_Alias.signin.amazonaws.cn/console/
Considerations before creating an account alias

  • Your Amazon Web Services account can have only one alias. If you create a new alias for your Amazon account, the new alias overwrites the previous alias, and the URL containing the previous alias stops working.

  • The account alias must contain only digits, lowercase letters, and hyphens. For more information on limitations on Amazon account entities, see IAM and Amazon STS quotas.

  • The account alias must be unique across all Amazon Web Services products within a given network partition.

    A partition is a group of Amazon Regions. Each Amazon account is scoped to one partition.

    The following are the supported partitions:

    • aws - Amazon Regions

    • aws-cn - China Regions

    • aws-us-gov - Amazon GovCloud (US) Regions

Note

Account aliases are not secrets, and they will appear in your public-facing sign-in page URL. Do not include any sensitive information in your account alias.

The original URL containing your Amazon Web Services account ID remains active and can be used after you create your Amazon Web Services account alias.
