Get AWS root account email address

get-display-name.py

import boto3

session = boto3.Session(profile_name='ariancho')
s3_client = session.client('s3')

display_name = s3_client.list_buckets()['Owner']['DisplayName']
print(display_name)

for bucket in s3_client.list_buckets()['Buckets']:
    print(s3_client.get_bucket_acl(Bucket=bucket['Name'])['Owner']['DisplayName'])

From Ben Bridts:

# Works if the AWS account has support cases
aws support describe-cases --region us-east-1 --include-resolved-cases --query cases[0].submittedBy --output text

# Works if the AWS credentials have privileges for AWS organizations and the credentials are associated with the AWS organization master account
aws organizations --profile root describe-account --account-id $(aws sts get-caller-identity --query Account --output text) --query Account.Email --output text

Another potential location for the AWS account root email address is SNS subscriptions.

aws sns list-subscriptions

If your AWS accounts are attached to an AWS Organisation, you can also see the aws root email address in the OU screen in the tree view:

https://us-east-1.console.aws.amazon.com/organizations/v2/home/accounts

This should list the root email of all of your Organisations associated accounts.

@andresriancho Good call on the support cases!
