InvalidResourceLocation - Invalid Resource Location: Region Not Available
The region/location value is wrong—format might be invalid (must be lowercase with no spaces like "eastus", not "East US"), the resource type isn't available there, or your subscription lacks access to a restricted region. This 400 client-side error occurs after ARM validates the location format but finds the provider doesn't support that resource type in that region, or you need approval for restricted regions (government clouds, some commercial regions). Resource availability varies by provider and region. Common in VM deployments, AKS cluster creation, Azure SQL database provisioning, and App Service deployments when using unsupported or restricted regions.
#Common Causes
- →Invalid Location Format: The location value doesn't match the canonical region identifier format. It must be lowercase with no spaces (e.g., "eastus" not "East US" or "EastUS"). ARM rejects locations that violate format rules before checking availability.
- →Resource Type Not Available in Region: The resource provider doesn't support this resource type in the specified region. Resource availability varies by provider and region. Some resource types are only available in specific regions.
- →Subscription Region Access Denied: Your subscription doesn't have access to a restricted region. Some regions (e.g., government clouds, restricted commercial regions) require support ticket approval before you can create resources there.
✓Solutions
- 1Step 1: Diagnose - List all available regions: az account list-locations --query "[].{name:name, displayName:displayName}" --output table
- 2Step 2: Diagnose - Check resource type locations: az provider show --namespace <provider-namespace> --query "resourceTypes[?resourceType=='<type>'].locations" --output table
- 3Step 3: Diagnose - Verify location format is correct—lowercase with no spaces (e.g., "eastus" not "East US").
- 4Step 4: Fix - Use a supported region from provider capabilities. Select a region from the locations array returned by the provider show command.
- 5Step 5: Fix - Request access to restricted regions through Azure Portal support ticket. Approval time varies.
- 6Step 6: Verify - Retry your resource creation operation with the supported region. It should succeed with HTTP 201 instead of 400 InvalidResourceLocation.

Location Validation and Region Availability
1# This script helps diagnose InvalidResourceLocation errors by validating regions
2
3# Step 1: List all available regions
4echo "Listing all available regions..."
5az account list-locations --query "[].{name:name, displayName:displayName, regionalDisplayName:regionalDisplayName}" --output table
6
7# Step 2: Example location (replace with your target location)
8LOCATION="eastus"

15 exit 1
16fi
17echo "Location format is valid"

19# Step 4: Check if location exists in available regions
