The USPS splits pricing across nine ‘zones’. Zone 1 covers areas beyond your zip code but within a 50 mile radius, while Zone 8 covers distances of 1801 miles and over (coast-to-coast shipping, essentially). Zone 9 is for Freely Associated States.Zones aren’t fixed, are defined by the distance between the sender’s and receiver’s locations. So, if you live in Washington, you’ll pay Zone 1/2 prices to ship to customers in neighboring Oregon, whereas a business based in New York would pay Zone 7/8 prices to ship to the same customers.USPS postage and shipping zonesZoneDistance1Non-local zones within a 50 mile radius251 to 150 mile radius3151 to 300 mile radius4301 to 600 mile radius5601 to 1000 mile radius61001 to 1400 mile radius71401 to 1800 mile radius81801 miles and overBox/Envelope TypeThe USPS is happy to ship letters and boxes with both standard and non-standard dimensions, charging a premium on heavier packages.But if all your mail tends to be of a similar size, you could save a ton of money if you use USPS’s Flat Rate boxes and envelopes. For a fixed fee, you can ship as much weight as you like (up to 70 lbs) for no extra cost. The trade-off is that your mail has to be small enough to fit inside USPS’s special Flat Rate boxes and envelopes, but it’s usually more than enough for most companies’ mailing needs.WeightThe maximum weight allowed for letters and packages sent by Priority Mail is 70 lb. If you’re using Flat Rate packaging (discussed above), you’ll pay the same whether you’re sending 1 lb or 70 lb. But if you’re using your own packaging, or if your packages exceed the maximum dimensions for Flat Rate shipping, then you’ll pay an additional amount for every extra pound of weight you send.Next StepsIf speedy shipping is a priority for you, you can’t go far wrong with Priority Mail. The USPS even throws in free Flat Rate packaging as an extra incentive to use their mailing services.A good way to cut down time spent sorting and weighing your mail is by leasing a postage meter. Postage meters automatically calculate mailing costs, and save your staff valuable time.To find out more, you can request quotes from top postage meter suppliers.
