UPS, FEDEX, USPS Shipping Zone Charts
        
            Shipping zones are used to 
                calculate shipping costs. For any two zip codes in the country there is
            a corresponding zone
                number. There are seven different zone numbers, 2-7. The farther two zip
            codes are from each other, the higher the zone number and shipping costs.
        
        
            For your convenience, this tool generates a zone chart for any zip code. This chart
            will contain all the zone numbers for the given zip code. Just enter the first 3-5
            digits of your zip code and click “Get Chart”
