[Display(Name="Credit card number:")]
[RegularExpression(@"\d{4}")]
public int BookingCardNumberFirstFour { get; set; }

<%: Html.TextBoxFor(model => model.BookingCardNumberFirstFour, new {style="width:40px;"}) %>

    You can use the range attribute.

    [Range(0,9999)]
public int myInt { get; set;}

    if you want them to enter exactly 4 digits use the regular expression attribute.

    [RegularExpression(@"\d{4}")]
public int myInt {get; set;}

<%: Html.EditorFor(model => model.BookingCardNumberFirstFour, new {style="width:40px;"}) %>
<%: Html.ValidationMessageFor(model => model.BookingCardNumberFirstFour) %>
