# List Supported Countries

Each Sudo Platform environment is configured to support Secure ID Verification of identities from a specific set of countries. To get a list of supported countries, use the `listSupportedCountries()` method. The results are ISO 3166-1 alpha-2 codes, e.g. `US` for the United States.

```swift
do {
    let countries = try await identityVerificationClient.listSupportedCountries()
} catch {
    // Handle error. An error may be thrown if the backend is unable to perform
    // requested operation due to availability or security issues.
    // An error might be also be thrown for unrecoverable circumstances arising
    // from programmatic error or configuration error. For example, if the keychain
    // access entitlement is not set up correctly or basic system resources are
    // unavailable.
}
```

```kotlin
CoroutineScope(Dispatchers.IO).launch {
    try {
        // countries: list of strings containing the country codes
        val countries = identityVerificationClient.listSupportedCountries()
    } catch (e: SudoIdentityVerificationException) {
        // Handle errors.
    }
}
```
