[ZipCode]
public string ZipCode { get; set; }

I know this doesn't work, but this is what I am looking for.

Answer 1

You need to use a Regex. Try something like this.

[Required(ErrorMessage = "Zip is Required")]
[RegularExpression(@"^\d{5}(-\d{4})?$", ErrorMessage = "Invalid Zip")]
public string Zip { get; set; }

Answer 2

[Display(Name = "Zip Code")]
[StringLength(10, MinimumLength = 5)]
[RegularExpression("(^\\d{5}(-\\d{4})?$)|(^[ABCEGHJKLMNPRSTVXY]{1}\\d{1}[A-Z]{1} *\\d{1}[A-Z]{1}\\d{1}$)", ErrorMessage = "Zip code is invalid.")] // US or Canada
[Required(ErrorMessage = "Zip Code is Required.")]
public String ZipCode { set; get; }
