I received a bill for AWS, but I don't have an account.
Resolution
First, make sure that the charges were from AWS. If your payment method is billed, then the payment method is associated with an account that has running resources.
The following are reasons why you might be billed for an account.
Someone used your payment method without your permission
If you own the payment method and don't have an account, then someone might be using your payment information without permission. If you're not associated with the account, then AWS Support can't resolve the charges.
Contact your credit card issuer to dispute the charges or report a stolen credit card.
A test account's Free Tier promotion expired
You can use the AWS Free Tier on new accounts for 1 year. If your resources continue to run after the Free Tier expires, then you're billed at the On-Demand rates. For more information, see How do I avoid future charges when I use the AWS Free Tier?
Someone in your organization created the account
Check whether other authorized users of your credit card used the credit card to open an account. If you use a corporate credit card, then check with the technical department within your organization. Common users of AWS include application or service developers, website designers, and systems administrators.
A contractor or third party used AWS to provide you a service
A contractor or third party that you hired might be using AWS to build your website or app. Contact the third party for more details about the charges.
To contact AWS Support when you don't have an account or can't sign in, use the I'm an AWS customer and I'm looking for billing or account support form. If you still can't resolve the issue, then respond to the original email that you received from AWS Support.
Important: If the account isn't verified, then AWS Support can't discuss any account-related information.
