If your S3 bucket is already set up in your AWS account, it is easy to collect the S3 bucket name.
- Log into the AWS console (https://console.aws.amazon.com). Navigate to Services, then select the S3 service.
- This opens the Amazon S3 bucket page. Your existing S3 bucket name is displayed in the Bucket Name list.
When you find the name of your S3 bucket, enter it into the AWS Add New Account form. See Fill In the AWS Add New Account Form.
