+title: EU region and data residency
+subtitle: Build and run your voice agents in Vapi's EU region.
+description: "Build in Vapi's EU region: the EU dashboard, API, and SIP endpoints, the outbound IP addresses to allowlist, and keeping your organization in-region."
+slug: security-and-privacy/eu-region
+---
+
+Vapi's EU region lets you build and run voice agents hosted in the European Union. If your organization is in the EU region, use the EU endpoints below for everything: the dashboard, API calls, and SIP.
+
+## EU region endpoints
+
+Each Vapi organization belongs to a single region, and every resource (assistants, tools, phone numbers, SIP trunk credentials) lives with it. Use the endpoints that match your organization's region.
+
+| | United States | European Union |
+| --- | --- | --- |
+| Dashboard | `dashboard.vapi.ai` | `dashboard.eu.vapi.ai` |
+| API base URL | `https://api.vapi.ai` | `https://api.eu.vapi.ai` |
+| SIP host | `sip.vapi.ai` | `sip.eu.vapi.ai` |
+
+## Build in the EU region
+
+If your organization is in the EU region, keep every request and resource on the EU endpoints:
+
+- Make API calls to `https://api.eu.vapi.ai` using a key from your EU dashboard.
+- Create SIP phone numbers and trunks with a `sipUri` on `sip.eu.vapi.ai`.
+- For SIP firewall allowlisting, use the EU addresses in the [SIP networking reference](/advanced/sip/sip-networking).
+
+Each region is a separate, isolated environment, so keep your API key, endpoints, and SIP host all in the same region.
+
+## EU outbound IP addresses
+
+Vapi's outbound HTTP requests from the EU region (webhooks, tool calls, and other requests to your server) originate from a fixed set of EU addresses. Allowlist these if your server restricts inbound traffic by IP:
+
+- `3.74.75.238/32`
+- `3.77.231.137/32`
+- `3.120.216.209/32`
+- `3.127.10.26/32`
+- `63.182.246.187/32`
+- `63.184.196.2/32`
