Can I put a limit on the amount that can be charged on my card?

While AWS doesn't offer a direct way to set a spending limit on your credit card, there are several methods you can use to control and monitor your AWS spending:

1. Set up a budget: You can create a custom budget in the AWS Billing Dashboard to set spending limits and receive notifications when you're approaching or exceeding those limits.

2. Enable billing alerts: In the AWS Billing Dashboard, you can enable "Receive Free Tier Usage Alerts" to get notified about your usage of free tier services.

3. Use AWS Cost Explorer: This tool helps you visualize and manage your AWS costs and usage over time.

4. Implement IAM policies: You can use AWS Identity and Access Management (IAM) to restrict access to certain services or actions, indirectly limiting potential charges.

5. Regularly review your bill: Check your AWS Billing Dashboard frequently to monitor your usage and charges.

While these methods don't directly limit charges on your card, they provide ways to closely monitor and control your AWS spending. If you're concerned about unexpected charges, it's best to implement a combination of these strategies and regularly review your account activity.

If you have specific concerns about billing or need to discuss your account, you can open a support case with AWS Billing Support for personalized assistance.

Like the GenAI Answer gave, there are no direct ways to set a spending limit on the card via AWS. You can use AWS Budget Actions to react to hitting budget thresholds to restrict users from using creating resources on your account via IAM and SCPs or Stopping EC2 or RDS instance in that particular account. You would need to create a budget and budget alert first to set up budget actions.
