This approach would actually work without the need for subsequent validation, if implemented properly. Not only as you noted does it let "259" through, but also it doesn't cover 2-digit numbers starting with 2. Assuming excess leading zeroes are illegal, the components required are: \d [1-9]\d 1\d\d 2[0-4]\d 25[0-5] > > This is of course only for one number.
