Phone Numbers should be stored as strings rather than numbers

Because:

  1. Some numbers start with 0 or + which cannot be stored in any numeric value (e.g. "002121132434" or "+9772323212"
  2. You will need to search for phone numbers as string (e.g. numbers starting with specific substrings represent specific regions or specific service providers)
  3. You will need to do some string formatting (e.g. "+977-232-3212")
  4. You will never need to do mathematical operation (e.g. you will never add or subtract 2 phone numbers)

Your range validator is not working because numeric do not support leading zero .. and range validator works on numeric type

It will be working using RegularExpression validator... something like this ...

[Required(ErrorMessageResourceType = typeof(App_Globaliz.Resource1), ErrorMessageResourceName = "Number")]
[Display(Name = "Number")]
[DataType(DataType.PhoneNumber)]
[RegularExpression(@"^\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$", ErrorMessage = "Not a valid number")]
public string PhoneNumber { get; set; }

Integers do not support leading zeros. You should not see this error if you try to set the value 9124573957. EDIT: this will only work if you use long instead of int to store the value, because 9124573957 is bigger than int.MaxValue.

If you have to support leading zeros, you have to store the value as string.

Number data types (int, double, etc.) are for doing Math! Just ask yourself: could it be useful to add two of those numbers, e.g. what's the meaning of the sum of your telephone number and your friend's? If that does not make sense at all, it is not a number.

Telephone numbers are strings, though they are commonly called numbers.
