# LocaleIdentifier

> Identifies a locale by its culture code, for example "en" or "fr-CA".

## Definition

* **Type:** Struct
* **Namespace:** [Unity.Localization](/engine/6000.7/script-reference/unity/localization.md)
* **Assembly:** UnityEngine.LocalizationRuntimeModule
* **Implements:** [IEquatable\<LocaleIdentifier>](https://learn.microsoft.com/dotnet/api/system.iequatable-1)

```csharp
public struct LocaleIdentifier : IEquatable<LocaleIdentifier>
```

## Remarks

This is the minimal identifier used to scope cached assets per locale. The full locale model (display name, fallbacks, formatting culture) lives on [Locale](/engine/6000.7/script-reference/unity/localization/locale.md). Two identifiers compare equal when their codes match, ignoring case. The default value is the undefined locale, whose [LocaleIdentifier.Code](/engine/6000.7/script-reference/unity/localization/localeidentifier/code.md) is the empty string.

Additional Resources: [Locale](/engine/6000.7/script-reference/unity/localization/locale.md), [ResourceTable](/engine/6000.7/script-reference/unity/localization/resourcetable.md), [SharedTableData](/engine/6000.7/script-reference/unity/localization/sharedtabledata.md)

Create an identifier from a code, then compare it against another case-insensitively.

## Examples

```csharp
using Unity.Localization;
using UnityEngine;

namespace Unity.Localization.Samples
{
    public class LocaleIdentifierOverviewExample
    {
        public void Run()
        {
            LocaleIdentifier identifier = "en";                     // implicit conversion from string

            Debug.Log(identifier.Code);                            // en
            Debug.Log(identifier == new LocaleIdentifier("EN"));   // True (case-insensitive)
        }
    }
}
```
