390390Claude in Amazon Bedrock is available in the following AWS regions. Amazon Bedrock offers two endpoint types:
391391
392392* **Global:** dynamic routing across all available regions for maximum availability. No pricing premium.
393* **Regional:** the endpoint resolves to the single AWS region you specify, for data-residency requirements. Regional endpoints carry a 10% pricing premium over global endpoints. To route across multiple regions within a geography, use an [inference profile](https://docs.aws.amazon.com/bedrock/latest/userguide/cross-region-inference.html) (US, EU, JP, or AU). Regions marked **In-region only** in the table support direct single-region routing without an inference profile.
