The Doc said a minimum of three separate availability zones are present in all available zone-enabled regions.
But the Azure portal only can select "Zone1, Zone2, Zone3" of all available zone-enabled regions.

  1. Are there definite three availability zones for each available zone-enabled region?
  2. How could I get the availability zones of one available zone-enabled region by API if the availability zone size is not three?

    If a region supports Availability Zones, there will be a minimum of 3 Availability Zones. Refer the below link to see the regions with availability Zones.

    https://learn.microsoft.com/en-us/azure/reliability/availability-zones-service-support#azure-regions-with-availability-zone-support

    If you want to explore all the regions and corresponding availability Zones use the following link.

    https://azure.microsoft.com/en-gb/explore/global-infrastructure/geographies/#geographies

    To retrieve the number of availability zones for a specific region, you can make a GET request to the following endpoint:

    https://management.azure.com/subscriptions/{subscriptionId}/providers/Microsoft.Compute/locations/{location}?api-version=2021-03-01

    Hope this helps
