Azure Resource Name Validator
Validate resource names against Azure's official naming rules and constraints.
Why Validate Azure Resource Names?
Every Azure resource type has specific naming rules — character restrictions, length limits, and scope requirements. A name that works for a Virtual Machine won't necessarily work for a Storage Account. Getting it wrong means failed deployments, broken Terraform plans, and wasted time debugging cryptic ARM errors.
This tool checks your proposed resource name against Microsoft's official naming rules in real time. Select a resource type, type a name, and get instant validation with clear error messages explaining exactly what needs to change.
Whether you're building naming conventions for an enterprise landing zone, validating names before writing IaC templates, or just checking a one-off deployment — this tool covers 60+ Azure resource types with up-to-date rules from Microsoft's documentation.
Frequently Asked Questions
What Azure resource types does this tool support?
The validator supports over 60 Azure resource types across compute, storage, networking, databases, app services, containers, integration, analytics, AI, security, management, monitoring, backup, and automation categories. Each resource type has its own character rules, length limits, and scope requirements sourced from Microsoft's official documentation.
Does this tool check real-time name availability in Azure?
No, this tool validates names against Azure's naming rules and constraints (character restrictions, length limits, disallowed prefixes/suffixes). It does not check whether a name is already in use. For globally unique resources like Storage Accounts or Key Vaults, you should also verify availability through the Azure Portal or CLI after passing validation here.
Can I use this tool to validate names for Terraform or Bicep templates?
Yes. The naming rules validated here are the same rules enforced by Azure Resource Manager, regardless of how you deploy. Validating names before writing your IaC templates saves you from deployment failures caused by invalid resource names.
How often are the naming rules updated?
The naming rules are sourced from Microsoft's official Azure resource naming documentation and updated regularly. The last update date is shown at the bottom of the tool. If you notice a discrepancy with the latest Azure docs, please reach out via the contact page.
What does 'Globally Unique' mean for a resource name?
Resources marked as 'Globally Unique' must have a name that is unique across all of Azure, not just within your subscription or resource group. This applies to resources with public-facing DNS names like Storage Accounts, Key Vaults, App Services, and SQL Servers.
