What are the formatting options for phone numbers and can I validate them?
### Field Types
        ![(iframe)](https://www.loom.com/embed/4332011493fc4dda9f5364a933adf651?hide_owner=true&hide_share=true&hide_title=true&hideEmbedTopBar=true)

You can select between U.S., Australian, or custom format phone numbers.

The Custom format phone number option allows you to specify the format you want. You can include a country code, parentheses, spaces, or dashes.

Phone number questions allow various formatting options, including:

 - No format (equivalent to not choosing a format)
 - US Phone Number
 - AU Phone number
 - Custom format

For all formats except "no format" the form will automatically enforce that the input matches the specified format. That is, forms perform validation – if the format is not met, respondents may not proceed to the next page and may not submit the form.

## Gotchas

*Validation* here does not mean that the phone number is checked and determined to be an active phone number. It only means that it adheres to the specified format.
