I think you need something like /\A[0-9]*\z/ or /\A\d*\z/ or possibly even better you could use something like validates_numericality_of :phone_code, :only_integer => true, :greater_than => 0 Though I think this would allow a leading + character.

I think > you need something like > /\A[0-9]*\z/ > or > /\A\d*\z/if you are going to use a regexp you might as well use validates_format_of rather than doing it yourself Fred
A Simple Example using RegExp:
<html>
<head>
<script language=''javascript''>
function CheckThis(obj) {
var strRegExp = /^[0-9]*$/;
if(!strRegExp.test(obj.value))
obj.value = '''';
}
</script>
</head>
<body>
<p>Insert your data number here:</p>
<input type=''text'' id=''test''
size=''10'' value=''''
onkeyup=''CheckThis(this);''/>
</body>
</html>
I don''t know if this can help you, i hope.
