There’s a lot of confusion out there when it comes to the different USPS zones. In fact, one of the most common questions people ask us is, “What USPS zone am I in?” In reality, the distance a package has to travel from its origin point (in miles) determines the different USPS zones—not an area’s physical location. For example, the distance between Los Angeles, CA and Portland, OR is roughly 960 miles. Therefore, sending a parcel from Los Angeles to Portland will be classified as Zone 5. This will determine the price of postage, along with the USPS mail class the package is sent in. Below is a chart of all the different USPS zones and their distances, for your reference.
Breakdown of the Different USPS Zones
- Zone 1: 1-50 miles
- Zone 2: 51-150 miles
- Zone 3: 151-300 miles
- Zone 4: 301-600 miles
- Zone 5: 601-1000 miles
- Zone 6: 1001-1400 miles
- Zone 7: 1401-1800 miles
- Zone 8: 1801 miles or greater
- Zone 9: Designated for Freely Associated States, for example when you ship to Guam, Palau and other US Territories
