Input Mask options are available under the General Settings panel, and only for the Single Line Text field and the Post Custom Field. They can provide more granular control over the permitted entry formats than the standard fields such as Phone Number or Address Postal Code.

Custom Input Masks
Input masks provide a visual guide allowing users to more easily enter data in a specific format such as dates and phone numbers. The input mask in the image above allows the user to add two digits for the month, two digits for the day, and four digits for the year. No letters or any other characters will work, only numbers.
Accepted Input Mask Characters
The following symbols are accepted as placeholders in input masks and provide some basic pattern matching.

Notes
A customer will only see underscores when they enter the field, which identifies the quantity of characters the field expects, but not their type. We recommend you provide additional visual help for complicated masks, such as a field description or a placeholder example. If the 「Enable password input」 advanced property is checked, it will override the input mask functionality.
