Troubleshooting an Amazon Bedrock OptInRequired 403 Error


Question

How Do I Fix an Amazon Bedrock OptInRequired 403 Error?

Clarifying the Issue

The OptInRequired error occurs when you attempt to access Amazon Bedrock but your AWS account has not yet been granted the necessary permissions. Specifically, this error message states:

OptInRequired: The AWS access key ID needs a subscription for the service. HTTP Status Code: 403

This means that while your AWS credentials may be correct, your account has not been opted into Amazon Bedrock or lacks the necessary service subscription.

Why It Matters

Amazon Bedrock provides foundational AI models for developing AI-powered applications. If you encounter this error, you won't be able to use the service until your account is properly configured. This can delay development and prevent access to key AI features.

Understanding how to resolve the OptInRequired error ensures smooth integration with Amazon Bedrock and prevents disruptions in your AI projects.

Key Terms

  • OptInRequired: An AWS error indicating that the user must manually subscribe to a service before using it.
  • Amazon Bedrock: An AWS service providing foundation models (FMs) for AI applications.
  • AWS IAM (Identity and Access Management): A service that manages access permissions for AWS resources.
  • Service Quotas: AWS limits on resource usage that may require account approval or adjustment.

Steps at a Glance

  1. Check Amazon Bedrock Availability – Ensure that the service is available in your AWS region.
  2. Subscribe to Amazon Bedrock – Opt in to the service through the AWS console.
  3. Verify IAM Permissions – Ensure that your AWS credentials have the correct policies attached.
  4. Check Service Quotas – Confirm that your AWS account has access to the necessary quotas.
  5. Retry the Request – After opting in and configuring permissions, test your access again.

Detailed Steps

1.  Check Amazon Bedrock Availability in Your Region
Amazon Bedrock is not yet available in all AWS regions. To check:

  • Go to the AWS Regional Services List: AWS Regional Services
  • Confirm that Amazon Bedrock is available in your selected AWS region.

If Bedrock is unavailable in your region, switch to a supported region (e.g., us-east-1 or us-west-2).

2.  Subscribe to Amazon Bedrock

To manually opt-in to Amazon Bedrock:

  • Sign in to your AWS account.
  • Open the Amazon Bedrock console: Amazon Bedrock
  • Click Get started or follow the prompt to request access.
  • If Amazon Bedrock requires approval from AWS, wait for confirmation before proceeding.

3. Verify IAM Permissions

Ensure your AWS credentials have the correct permissions:

  • Open the AWS IAM console: AWS IAM
  • Navigate to Users > Your User > Permissions
  • Ensure your user has the following policies attached:
    - BedrockFullAccess
    - AmazonBedrockServiceRolePolicy
    - AmazonBedrockFoundationModelPolicy (if applicable)
  • If missing, attach the required policies using the Attach policies button.

4. Check Service Quotas

Amazon Bedrock may require quota approvals before use:

  • Open the AWS Service Quotas console: AWS Service Quotas
  • Search for Amazon Bedrock quotas.
  • If any limits are too low, click Request increase and submit the request.

5. Retry the Request

After subscribing and updating permissions, wait a few minutes and try accessing Bedrock again using the AWS CLI or SDK:

Bash
aws bedrock list-foundation-models --region us-east-1

If the command runs successfully, your access is now working. If the error persists, verify that your AWS subscription has been processed.

Conclusion

The OptInRequired 403 error in Amazon Bedrock is a common issue for new users who have not yet opted into the service. By following these steps—checking availability, subscribing, updating IAM permissions, and reviewing service quotas—you can quickly resolve the issue and start using Amazon Bedrock for AI development.

If the error persists after these steps, contact AWS Support for assistance. 🚀
