Hi Johny try this... 123-456-7890 => \d{3}-\d{3}-\d{4} 1234567890 = > ^([1-9]{1})([0-9]{9})$ 123-456-7890 => ^(1?(-?\d{3})-?)?(\d{3})(-?\d{4})$ more info: http://msdn.microsoft.com/en-us/library/ff650303.aspx http://www.zparacha.com/phone_number_regex/#.T4a4llH9PdM

In the same order the expressions needed are: @^\d{10}$ @^\d{3} \d{3} \d{4}$ @^\d{3}-\d{3}-\d{4}$
