JavaScript Number preserve leading 0

in Education by
I have a problem, I build a very simple javascript search for postal codes. I am using JS Numbers because I want to check if the passed number (search term) is less||equal or more||equal to the max and min. value >= splitZips[0] && value <= splitZips[1] But the Javascript Number var type deletes leading 0, which is a problem because I have postal codes like 01075 and also postal codes like 8430. So it can not find the small 4 digit codes. Any idea how to fix this?

Represent them as a String. Outside of strict mode, a leading zero denotes an octal number otherwise. Also, why would a leading zero have any significance when calculating numbers? Just use parseInt(num, 10) if you need to.
