Issue: Phone Number Field Accepts Letters, and Any Number of Digits

    It's true that some people use letters instead of numbers in their phone number. 

    Also, it accepts one single digit as a phone number. 

    Example, I can enter:

    Area Code: "X"  Phone Number: "X"

    Your phone number widget accepts this as a valid phone number. In no country is "X" a valid phone number. 

    This makes it impossible to validate phone numbers. 


    Please add the following properties:

    -"Accept Letters" Yes/No

    -Country: the widget should automatically adjust number of digits required based on the country.

    It is not a bug actually. But there is no validation on the phone field. It can only check if the user has entered something when you enable the required option.

    The workaround is to use the regular textbox field and put Numeric validation on it.


    I will forward your suggestion to our next level support since it do have merit on it.

    We will update you via this thread about its progress.

    We have added a new feature into the Phone Question, we called it the Phone masking, the validation of phonenumber input is now depends on how the form owner put the masking.

    For example. the default masking is ####-#####, the # symbols represent the numbers to be entered. Try it and let me know your comments. Please try to clean your browser cache to get the latest updates.

    Thank you,

    Does not work. 

    I created the following mask:


    Then i tested the form.

    I was able to enter:


    in the phone number fields. It was accepted. 

    Then i cleared my browser cache, and tried again. 

    Same result. 

    Your phone number validation does not seem to work.

    Are you refering to this form of yours ?

    I checked this form, and see that the phone field does not have its input mask property  set to ON

    You have to set ON the input mask for it to work.

    I tested it on a cloned form of yours. I enabled the input mask ON


    The effect is immediate on this form

    Please check and try again. Inform us if the issue persist.
