Route53 "Domain registration wasn't charged"

It's important to note that while you may have successfully registered domains through Route 53, there are a few factors to consider regarding the charges:

1. Delayed billing: AWS billing for domain registrations may not be immediate. It can take some time for the charges to appear on your account and be reflected in your invoices.

2. Credits don't apply: If you have AWS credits on your account, it's crucial to understand that these credits cannot be used for domain registration fees. Domain registration costs are always charged separately and are not eligible for credit coverage.

3. Billing cycle: AWS typically bills on a monthly cycle. Depending on when you registered the domains, the charges might appear on your next billing statement.

4. Checking the right place: Ensure you're looking at the correct billing section in your AWS account. Domain registration fees should appear under the Route 53 section of your bill.

5. Pending status: In some cases, there might be a delay between successful registration and the finalization of the billing process.

If you continue to not see any charges after a reasonable period (e.g., after your next billing cycle), it would be advisable to contact AWS Support directly. They can provide specific information about your account and the status of your domain registration charges. Remember, even if you don't see the charges immediately, you are still responsible for the domain registration fees.
