Find the AWS account number

The AWS account number uniquely identifies the AWs account you are working with. All AWS “arn” identifiers contain it, and you need to know it when you want to share AMIs with other accounts.

If there are no resources created yet in the account, you can find the account number in the “arn” of your user account.

1. Log into the AWS Console
2. In the upper right corner click your username and select My Security Credentials
   
3. On the left side select Users, and click any of the usernames in the list
   
4. The account number is part of the “User ARN”
