# US phone

## What it does

This component represents a US phone number. It:

* *validates* the stored format to make sure it contains exactly 10 digits.
* *removes* all `()*-[].#/'':` characters from the input string before storing the value.
* *formats* the value as `(123) 456-7890` when displaying the value, but only if the stored value is only made of digits.
