Create a subdomain zone using Terraform

Last updated Apr 21, 2026 A subdomain zone lets you manage a subdomain in a separate Cloudflare zone from the parent domain. This is useful for access control and team management. This guide shows how to automate the setup using the Cloudflare Terraform provider ↗︎. It is only available for Enterprise accounts

NOTE: subdomain setup is only available for Enterprise accounts

Prerequisites

Create the zone

Create a cloudflare_zone resource for the subdomain zone. The following example creates a zone for subdomain.example.com:

resource "cloudflare_zone" "subdomain_example_com" {
  account = {
    id = var.cloudflare_account_id
  }
  name = "subdomain.example.com"
  type = "full"
}

Terraform creates the zone in a Pending state. You must add NS delegation records to the parent zone before Cloudflare activates it.

Note

Refer to the cloudflare_zone docs ↗︎ in the Terraform provider documentation when you need to reference other zone properties.
