RegEx: How to limit a string to be either x characters OR y characters

Been trying to set a field's behavior limitation to allow users to only enter 11 or 14 digits. the best I came up so far is to limit the range to be between 11 and 14, but I need it to be either or.

^([0-9]{11,14})+$

Can anyone help?

Another way to do the job:

^[0-9]{11}(?:[0-9]{3})?$

You can use | for alternation

^([0-9]{11}|[0-9]{14})$

The above regex match either 11 or 14 digit string

Use or (|):

^([0-9]{11}|[0-9]{14})$
