            try {
                long phoneNumber = Long.parseLong(mvrUserPhone);
                System.out.println(phoneNumber);
            } catch (Exception ex) {
                errorMessage = errorMessage + "<br />- Invalid phone number.<br /> 
(Please enter phone number in xxx-xxx-xxxx format)";

You can do it like this using javascript for phone number as a example (taken from http://saikiran78.wordpress.com/2011/04/20/phone-number-validation-using-jquery/):

function ValidatePhone() {
    var phoneRegExp = 
        /^((\+)?[1-9]{1,2})?([-\s\.])?((\(\d{1,4}\))|\d{1,4})(([-\s\.])?[0-9]{1,12}){1,2}$/;
    var phoneVal = $("#txtPhone").val();
    var numbers = phoneVal.split("").length;
    if (10 <= numbers && numbers <= 20 && phoneRegExp.test(phoneVal)) {
        alert("SUCCESS");
    }
}
