What is FedEx One Rate?

FedEx One Rate is also known as Flat Rate which refers to regular or uniform shipping rates applicable for all types of packages, irrespective of the product’s weight, size, or dimensions.

This Flat Rate is calculated based on the store’s location and delivery zone of the item. In a specific region all customers can pay a uniform rate, which is ideal for customers who live near your store’s location. This shipping service is efficient if you have regular customers, but it’s important to consider that the delivery is predetermined and cannot be changed. 

Currently FedEx One Rate shipping is only available for items that weigh 50 pounds or less and the delivery location is based in the domestic regions of the United States.

FedEx has 12 free packaging options such as envelopes, tubes, flat rate boxes, etc. You can check the detailed table below.
