A Field Mask requires the user to input text data in a specific format.
Adding a Field Mask
Field Masks come in handy if you have a zip code field that needs to be a five digit number, or a customer ID that is always two letters followed by a four-digit number. This is a tool admins and designers can use to guide their users to provide correct responses when a drop down or multi-choice field type is not appropriate.
Field Masks can be applied to Text fields in the Style of Single Line or Barcode fields.
- Find an existing Barcode or Single Line Text field or add one to the workspace.
- Select the field's gear icon to open the Field Settings modal.
- Toggle to the More tab.
- Enter the desired field mask.
Types of Field Masks
There eight different types of field masks. Each character requires a different response. Below is a list of the different characters that can be part of a valid field mask and their meanings.
| Required | Optional |
| 0: Digit | 9: Digit |
| L: Letter | l: Letter |
| A: Digit or Letter | a: Digit or letter |
| ?: Digit, letter, space, symbol, etc. |
Wildcard: * is used to signify an undetermined number of characters.
Note
Asterisk is used for "Starts with" (e. g. 000*) or "Ends with" (e.g. *AAA) but only one wildcard character is allowed per mask and it MUST be the first or last character.
Examples of Field Mask in Use
If we setup a field mask on a field of AAA* this means that when responding, the user must enter text that meets the following criteria:
- The response MUST be at least three characters, but can be longer.
- The first three characters in the response must be either numbers or letters, they cannot be left blank or contain any symbols.

| 123456 | &78 4 |
| ABCDE | ...567 |

If we setup a Field Mask with 09a? this means that when responding, the user must enter text that meets the following:
- The response MUST be at four characters.
- The first character MUST be a number.
- The second character can be a number or a space.
- The third character can be a number, a letter, or a space.
