How can I check which region my Neon project is running in?

Quick answer

There are three quick ways to see your project's region: check the Settings widget on the Project Dashboard in the Console, run neon projects get <project_id> in the CLI, or read the region segment of your connection string hostname.

Console

Open the Neon Console and select the project.
On the Project Dashboard, find the Settings widget.
The region is listed there alongside the cloud provider.

See Project settings.

CLI

The projects get and projects list commands include the region ID in their output.

neon projects list

┌────────────────────────┬──────────┬───────────────┬──────────────────────┐
│ Id                     │ Name     │ Region Id     │ Created At           │
├────────────────────────┼──────────┼───────────────┼──────────────────────┤
│ crimson-voice-12345678 │ frontend │ aws-us-east-2 │ 2024-04-15T11:17:30Z │
└────────────────────────┴──────────┴───────────────┴──────────────────────┘

Or for a specific project:

neon projects get crimson-voice-12345678

See neon projects get.

Connection string

The region is embedded in the hostname segment of your connection string. Take this example:

postgresql://alex:AbC123dEf@ep-cool-darkness-a1b2c3d4-pooler.us-east-2.aws.neon.tech/dbname?sslmode=require&channel_binding=require

Read backwards from .aws.neon.tech (or .azure.neon.tech). The segment immediately before is the region:

us-east-2.aws.neon.tech → AWS US East (Ohio)
eu-central-1.aws.neon.tech → AWS EU Central (Frankfurt)
ap-southeast-1.aws.neon.tech → AWS Asia Pacific (Singapore)
eastus2.azure.neon.tech → Azure East US 2

The ep-cool-darkness-a1b2c3d4 portion is the compute ID, not the region.

All branches share the project's region

You can't run different branches in different regions. If you need to confirm where any specific branch's data lives, look up the parent project's region.

API

If you need the region programmatically:

curl "https://console.neon.tech/api/v2/projects/$PROJECT_ID" \
  -H "Authorization: Bearer $NEON_API_KEY" \
  -H "Accept: application/json" | jq '.project.region_id'

The region_id field uses the same identifiers as the CLI (aws-us-east-2, azure-eastus2, etc.).
