Request to enable Anthropic (Claude) model access in Amazon Bedrock

Question

Hello AWS Team,

I am the root user of AWS account in region us-east-1.
I’m trying to use Anthropic (Claude) models via Amazon Bedrock, but the models show `"modelAccessStatus": null` when listing foundation models, and invoking them returns the following error:

> ValidationException: Operation not allowed

Additionally, the “Submit use-case” option no longer appears in the Bedrock console.

**Intended use:**
- Learning and experimentation with AWS Bedrock APIs for educational and development testing (non-commercial)
- No sensitive or private data will be used
- Audience: personal/internal learning only

How to enable access to the Anthropic Claude models (such as `anthropic.claude-3-5-sonnet-20241022-v2:0`) for my account.

Thank you very much for your help.

This issue typically occurs when AWS Marketplace permissions have not been enabled for the account. Please ensure that Marketplace access is turned on under Billing → Marketplace settings, and that your IAM or root user has permission to subscribe to third-party models.

Once Marketplace permissions are enabled, Anthropic (Claude) models in Bedrock should display a valid modelAccessStatus and allow invocation.
