USPS Zone Map Lookup

Shipping zones are used by the carriers for mapping the distance traveled by a package. Therefore, a zone is measured in zip codes instead of miles, starting from the inception point to the ultimate destination.

Primarily, shipping zones are geographical domains to where the carriers ship. These zones span from Zone number 1 to 8 in domestic shipments, specifically in the US. In addition, shipping zones are used by the carriers for mapping the distance traveled by a package. Therefore, a zone is measured in zip codes instead of miles, starting from the inception point to the ultimate destination.  

The origin point is the one from where the order is shipped, which is also Zone 1. Similarly, the address to which it is sent is called the destination zone. However, the number for the destination zone relies upon its distance from the origin. Zone number 8 is the most distant of all.

What is the USPS Shipping Zone

Many small businesses go for USPS due to its cost-effective characteristics as well as its reliability. However, most sellers do not use the distribution centers; instead, they strategize about the mode of their shipping of goods for customers across more than 2500 miles of coasts.   As USPS shipping zones do cover the distance starting from the origin, one may use the shipping zone to estimate the duration it will take to make the product reach the customer.  

How to Calculate Shipping Zones

In general, the calculation of zones is done dynamically by the point from where the package is shipped. This could indicate that products that are being shipped from two distinct origin points to the same address or destination can be sent to entirely different zones.  
For example, shipping from Los Angeles to Missouri is done to Zone number 7. However, if shipped from Dallas to Missouri, the shipping is done to Zone number 4.

Shipping Zones Effect on Cost

In general, the shipping carriers do make use of the zones for the calculation of rates associated with specific services. Certain services make use of flat rates, and those allow you to pay an equal price, irrespective of the destination, provided that it must be inside the US.  

USPS does segmentation of the services being zoned and that are not zoned. So, if the services are zoned, the bigger the zone, the bigger the expense on most occasions.

Shipping Zones Effect On Delivery Speed

Upon a package being delivered to a nearby zone, no matter whether it is Zone 1 or 2, it can reach a minimum number of days, compared to the packages being delivered to greater zones. Cutting down the transition time is undoubtedly crucial, considering that the slowness of shipping can make things costly for the concerned customer. Noteworthy here is that around 73 percent of shoppers want cost-effective and swifter deliveries. On the other hand, 24 percent do cancel the orders for slow shipping.

Modern-day customers believe that the highest number of days that are acceptable to wait is just 4.1 days. However, in 2012 it was 5.5 days instead.

If the entire inventory gets accomplished from a single point, like, exterior to New Jersey, the process may take more than six days to deliver orders to someone in Oregon.  

What Is The Most Suitable Destination To Fulfill Orders To Lower Shipping Zones?

The shipping destination should essentially be close to that of the customers, which one can determine upon analyzing the history of the past orders.

If customers' geographical distribution occurs, fulfillment of an order that is outsourced in big cities can help reach more people at a much faster rate. Compared to that of shipping from a place with comparatively lesser population density, which can't effectively reach many people.

How Do eCommerce Stores Manage To Deliver Shipping For Free?

Most people inquire about the way eCommerce companies manage to ship absolutely for free. It might look confusing to think of free shipping of products; specifically, on those occasions when delivering the orders to the higher zones can be very costly. eCommerce companies, while providing free shipping as part of their pricing model, should be strategic enough to make decisions for ensuring that the same doesn't affect their margin. In general, this can be done upon taking any of the below options into account.  

All in all, by having clarity about the shipping zone, one can certainly manage to satisfy customers better by optimizing the strategy of fulfillment. Furthermore, this helps in understanding the expectation of the customers better and how to make deliveries cost-effective.
