Regular Expression To Validate Phone Number In MVC

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)
