Add a USPS Ship Wallet Account from the Dashboard

Overview

This guide describes how to create and authorize a USPS Ship Wallet account using the EasyPost Dashboard.

USPS Ship Wallet accounts are enabled in the Dashboard using different URLs depending on the account type. The setup flow is the same after the account is enabled.

• USPS Business Customer Gateway (BCG) login
• Enterprise Payment Account (EPA)
• Customer Registration ID (CRID)
• Mailer ID (MID)
• Manifest MID
• Returns MID 
• NSA Contract Number

Update the Carrier Account

14. Enter the EPS (EPA), CRID, Mailer ID, and Manifest (Master) ID values. Note: the Mailer ID and Manifest ID are often the same number.
    • USPS Ship Account number = EPS/EPA Account Number
    • USPS Ship Account Customer Registration ID = CRID
    • USPS Mailer ID = Mailer ID/MID
    • USPS Manifest ID (Optional) = “Master” MID
    • USPS Ship Returns ID (Optional) = Returns MID
    • USPS Ship Secondary Account Number (Optional) = Platform EPA; not applicable to all users
      Optional Fields
    • USPS Ship Manifest ID (Master MID): Used when manifesting shipments. If not provided, the Mailer ID is used by default.
    • USPS Ship Returns Mailer ID: Used to generate return labels with a different MID than outbound shipments. If not provided, the Mailer ID is used by default.
    • USPS Ship Secondary Account Number: Optional EPA used for additional rate visibility during rating. This does not affect pricing. For example, platforms using both an EPA and an MRC EPA can expose both rates in the same response. When provided, the associated EPA rate is mapped to rate.list_rate. If not provided, rate.list_rate defaults to the commercial rate.
      Note: The Mailer ID and Manifest ID are often the same value.
15. Click Save.
