make sure that your text box takes maximum input of 4 characters that also only numbers and no special characters alphabets and space or a dot
i will suggest you to do the first level of test by using a regularexpression validator then only verify again at the server side - why do you want to do a round trip for this kind of verification which can be easily done on the client side by regularexpression validator and the expression will be whats defined by TimCottee in the previous comment
