Yes, you can. In your Form Editor, go to Specific Fields and add a Phone field. Then, select from the Number format dropdown list the format that suits your needs.
If you need a phone format that’s not on the list, use a Short text field instead. This will not limit users to a specific format and you can also enable the Prefix option. In the prefix input box, you can type in your country code.
Pro Tip: Use a Short Text field and set the Field validation to regular expression. This way, you can add a regex code to define your desired phone format.
