# Regions

> Context Router base URLs per region, and how caching is scoped to the region you call.

Each region has its own Context Router base URL. Call the region closest to your
callers, or the one SLNG gave you. Requests are not routed between regions.

For the same regions alongside the speech and agent endpoints, see
[Region availability](/guides/regions/regions-map).

| Region                                                                                                                                                                                                                                                                                                                                        | Context Router endpoint                      |

## Caching regions

Caching is region aware and scoped to your organization. Your requests are never
processed or cached in another region.
