    You’re comparing characters with integers, so currently you’re comparing them with the control characters U+0003 and U+0004 – you want to compare them with characters representing the digits:

    if (zipCode.charAt(0) <= '3')
...
if (zipCode.charAt(0) >= '4')
    if (zipCode.charAt(0) <= '6')

    (You might consider using a switch statement too…)

    I’ve no idea whether this is correct in terms of what zip codes mean, but that’s the immediate problem with your code.
