The USPS offers a number of high-volume special rates for their different service levels:

  • Commercial Base Pricing (CBP): This pricing tier, which is the standard for online postage, offers significant savings compared to the retail rates you'll pay at the post office.
  • Commercial Plus Pricing (CPP): This pricing tier, which offers more cost savings than CBP, requires the following volumes in order to qualify:
    • First Class - 5,000 pieces in prior year
    • Priority - 50,000 pieces in prior year
    • Express - 5,000 pieces in prior year

We offer Commercial Plus Pricing on all EasyPost accounts. Sign Up and get started.
