Hi Ravi,
You can customize regular expression for your length. Either may be any plugin or any attribute for min and max length for telephone field shortcode. You can look into it.Please let me know if you have any other queries.Thanks
And how do I customise the error message that comes if filed does not fulfill the condition?
