You can use data anotations on the model property of this phonenumber. But remember to test it thoroughly for the country/region you are developing for as different countries may have different possible phone numbers. (This is business requirement though) code in model: [Required(ErrorMessage = Phone Number is needed. )] [Display(Name = Phone)] [DataType(DataType.PhoneNumber)] [RegularExpression(@ ^$?([0-9]{3})$?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$  ErrorMessage = Invalid Phone number )] public string PhoneNumber { get ; set ; } code in view: @Html.LabelFor( model = > model.PhoneNumber) @Html.EditorFor( model = > model.PhoneNumber) @Html.ValidationMessageFor( model = > model.PhoneNumber)
