What is USPS Commercial Pricing?

Up until Jan. 22, 2023 USPS has two commercial pricing categories: Commercial Base Pricing (CBP) and Commercial Plus Pricing (CPP). On Jan. 22, 2023 USPS will be collapsing these into one Commercial pricing category. There are several other types of USPS pricing and the rate you're getting is important: USPS Retail Pricing is the starting tier for pricing. This is the USPS rate you'll pay at your local Post Office or other retail locations. Commercial Pricing offers savings over USPS Retail. Commercial Pricing is offered with all EasyPost accounts by default which offers you postage savings over the Retail rate. Sign up now and get started.
