This guide will teach you what makes USPS different from other carriers.
The goal of this guide is to detail the best and cheapest ways to use USPS. We will walk you through the United States Postal Service's competitive pricing, predefined parcels, service levels, labels structures, and pick-up guidelines.
USPS has multiple service levels to support your business' every need. Naturally, the price of shipping parcels increases as the delivery time decreases. EasyPost supports all of USPS' functionality, along with the full functionality of 124 other carriers.
If you haven't shipped your first label with EasyPost, we recommend you check out our Getting Started Guide.
