Parcel Data Exchange (PDX) API
Parcel Data Exchange (PDX) is accessed via the web and Application Programming Interface (API) to allow customers to send manifest files and receive outbound files from the United States Postal Service® (USPS®).
Who should use the PDX API?
All Web Service calls require a USPS® Business Customer Gateway (BCG) username and password. If you do not already have a BCG account, go to https://gateway.usps.com and click the ‘Register for free’ button to create a username and password.
The Parcel Data Exchange (PDX) provides parcel shippers an additional option to transmit Shipping Service Files and retrieve data extracts and error-warning reports through a secure web service interface rather than through the conventional FTP/SFTP method. This application bypasses the Data Transfer Services (DTS) account configuration process, allowing a USPS Shipping customer to enroll online and begin shipping packages within the same day. Users can access the application through the Business Customer Gateway or through an Application Programming Interface (API) connection. The PDX application is available free of charge for business customers and third-party vendors.

The Intelligent Mail Package Barcode (IMpb) provides the best commercial prices with the largest discount available, piece-level tracking information at no additional charge for most products, and access to new products, services, and enhanced features. The addition of two (2) supplemental IMmb’s to the existing IMpb on a USPS shipping label results in enhanced package visibility with less mail rework.
The Mailer Identifier (MID) is a field within the Intelligent Mail barcode that is used to identify mailers. MIDs are assigned by the USPS® to a Mail Owner, Mailing Agent or other service providers who request them.
The USPS® Customer Registration ID (CRID) is a unique number that identifies a specific business location involved in a mailing. In order to submit electronic documentation (and receive Full-Service benefits), customers must have a customer registration ID assigned to their business location.
The Intelligent Mail barcode (IMb) is used to identify mailpiece movement through the postal system and support any additional services requested for that mailpiece. The STID defines the mailpiece as full-service or basic (non-automation) and is also used to determine the disposition of undeliverable-as-addressed (UAA) mail and the form of address correction that a mailer desires if any.
