# Supported Regions for cross-Region guardrail inference
<a name="guardrails-cross-region-support"></a>

Cross-Region inference with Amazon Bedrock Guardrails lets you seamlessly manage unplanned traffic bursts by utilizing compute across different AWS Regions for your guardrail policy evaluations.

When [creating](https://docs.aws.amazon.com/bedrock/latest/userguide/guardrails-components.html) or [modifying](https://docs.aws.amazon.com/bedrock/latest/userguide/guardrails-edit.html) a guardrail, you specify a guardrail profile that supports a set of source and destination Regions:
+ **Source Region** – A Region where you make the guardrail inference request.
+ **Destination Region** – A Region where the Amazon Bedrock service can route the guardrail inference request.

The guardrail profiles that you can use depend on the source Region where your guardrail resides.

## Available guardrail profiles

Expand one of the following sections to see information about a guardrail profile, the source Regions from which it can be used, and the destination Regions to which it can route requests.

### US Guardrail v1:0
<a name="guardrail-profiles-us-guardrail"></a>

To use a guardrail profile in the US geographic boundary, specify the following guardrail profile ID or Amazon Resource Name (ARN) in one of the source Regions:
