Enforcing data residency with single-Region Claude Code on Amazon Bedrock
AWS Zaid Barkat
Anthropic published a technical guide for running Claude Code on Amazon Bedrock with data residency enforcement to a single AWS Region. For London (eu-west-2), users must create application inference profiles and apply IAM Region conditions; for other supported regions like Ireland or Tokyo, users can leverage Mantle's native single-Region routing with environment variables. The setup requires IAM policies with aws:RequestedRegion conditions and verification through AWS CloudTrail to ensure all model inference stays within the specified region.
Why it matters
A regulated customer needed all Claude Code inference processed in a single AWS Region (London), not just in-geography. This post shows two ways to pin Claude Code on Amazon Bedrock to one Region: an application inference profile or the Mantle endpoint, paired with an IAM Region condition, plus how to verify compliance in AWS CloudTrail.
