To find out which region your Datadog account is set up in, you can use several quick methods.
1️⃣ Check the URL (Fastest Method)
Look at the URL when you're logged into Datadog.
Different regions use different domains:
| Region | URL Pattern |
| ---------------------- | --------------------------- |
| US1 (Default US) | https://app.datadoghq.com |
| US3 | https://us3.datadoghq.com |
| US5 | https://us5.datadoghq.com |
| EU | https://app.datadoghq.eu |
| AP1 (Asia Pacific) | https://ap1.datadoghq.com |
| US1-FED (Gov) | https://app.ddog-gov.com |
👉 Example:
If you're logged in at:
https://us5.datadoghq.com/dashboard/abc
Your region = US5
2️⃣ Check in Datadog UI (Organization Settings)
Click your profile icon (bottom left)
Go to Organization Settings
Look for:
Site
API endpoint
Datadog site URL
It will show the regional site.
3️⃣ Check Agent Configuration (On Server)
On your server where Datadog agent is installed:
Linux:
cat /etc/datadog-agent/datadog.yaml | grep site
You may see:
site: datadoghq.eu
That means → EU region
Common values:
| site value | Region |
| ----------------- | ------ |
| datadoghq.com | US1 |
| us3.datadoghq.com | US3 |
| us5.datadoghq.com | US5 |
| datadoghq.eu | EU |
| ap1.datadoghq.com | AP1 |
4️⃣ Check API Key Creation Page
Go to:
👉 Organization Settings → API Keys
The URL there also reflects your region.
5️⃣ If Using Environment Variable
Check if DD_SITE is set:
echo $DD_SITE
Example:
DD_SITE=datadoghq.eu
⚠ Why Region Matters
It affects:
- Agent configuration
- API endpoint
- Logs/metrics ingestion endpoint
- Cross-region data transfer
- Compliance (EU vs US data residency)
🎯 Quick Summary
Most common cases:
- If URL ends with
.com → US
- If URL ends with
.eu → Europe
- If it has
ap1 → Asia Pacific
If you share the login URL (remove org info), I can confirm the exact region for you.
