## Validation

When phone validation is enabled, the input is checked against the selected country's phone number format. Invalid numbers show a validation error.

## Data Format

```json theme={null}
{ "field_name": "+1 (555) 123-4567" }
```

<Tip>Phone numbers are stored as entered by the user. If you need a standardized format for Klaviyo, consider using the E.164 format validation.</Tip>
