Region code names
When the location parameter is used in a command or request, you need to provide the region code name as the location value. To get the code name of the region that your private mobile network is in, run the following command in the Azure CLI.
az account list-locations -o table
The output of this command is a table of the names and locations for all the Azure regions that your subscription supports. Navigate to the Azure region that has the DisplayName you are looking for and use its Name value for the location parameter.
For example, if you're deploying in the East US region, use eastus for the location parameter.
DisplayName Name RegionalDisplayName
------------------------ ------------------- -------------------------------------
East US eastus (US) East US
West Europe westeurope (Europe) West Europe
